Fuel Safety
DANGER
GASOLINE, GASOLINE VAPORS, AND PROPANE ARE HIGHLY
FLAMMABLE AND EXPLOSIVE
Fire or explosion can cause severe burns or death.
Gasoline and gasoline vapors:
– Gasoline vapors are highly flammable and explosive.
– Gasoline vapors can cause a fire or explosion if ignited.
– Gasoline is a liquid fuel and the resulting gasoline vapors can
ignite and cause a fire or explosion.
– Gasoline is a skin irritant and needs to be cleaned up
immediately if spilled on skin or clothes.
– Gasoline has a distinctive odor, this will help detect potential
leaks quickly.
– In any petroleum gas fire, flames should not be extinguished
unless by doing so the fuel supply valve can be turned OFF.
This is because if a fire is extinguished and a supply of fuel is
not turned OFF, then an explosion hazard could be created.
– Gasoline vapors expand and contract with ambient
temperatures. Never fill the gasoline tank past the red FULL
indicator on the fuel filter, as gasoline vapors needs room to
expand if temperatures rise.
WARNING
Propane/LPG (liquified petroleum gas) and LPG Vapors:
– LPG is a hydrocarbon gas that exists in a liquified form and
it’s vapors are highly flammable and explosive.
– LPG and it’s vapors are under pressure and can cause a
fire or explosion if ignited.
– LPG vapors are heavier than air and will settle in low
places while dissipating.
– LPG itself is odorless and tasteless. For safety, a chemical
is added to give it an odor to help detect leaks quickly.
– If a leak is detected, IMMEDIATELY turn OFF the gas
supply.
– In the event of an LPG fire and only when safe to do so,
first close the regulator valve OFF and then use a dry
powder extinguisher to put out the fire. This is because if
a fire is extinguished before the regulator valve is closed
OFF, then an explosion hazard condition could be created.
– Always keep the LPG cylinder in an upright position.
– LPG is a skin irritant and can cause severe cold burns
similar to frostbite.
– Always wear proper protective gloves when connecting to
and disconnecting from a propane bottle.
– Always keep LPG away from sparks, open flames, pilot
lights, heat and other sources of ignition.
WARNING
When adding or removing gasoline:
DO NOT light or smoke cigarettes.
Always stop the engine and allow to cool for a minimum of two
minutes before refueling.
Always loosen gasoline cap slowly to release vapor pressure
and to keep fuel from escaping around the gasoline cap.
Always replace and tighten the gasoline cap securely after
fueling.
Never remove the gasoline cap or add gasoline while the
engine is running or when the engine is hot.
Only fill or drain gasoline outdoors in a well-ventilated area.
DO NOT pump gasoline directly into the generator at the gas
station.
Always store gasoline in an EPA/CARB compliant container or
to transfer the gasoline to the generator.
DO NOT overfill the gasoline tank.
Always keep gasoline, propane and natural gas vapors away
from sparks, open flames, pilot lights, heat and other sources
of ignition.

Always check that the gasoline cap, air filter, spark plug, fuel
lines and exhaust system are properly in place.
Always allow spilled gasoline to evaporate fully before
attempting to start the engine.
Always check the connections of the supply hose for leaks
before using LPG fuel.
Always be certain that the generator is resting firmly on level
ground.
WARNING
When operating the generator:
DO NOT move or tip the generator during operation.
WARNING
When transporting or servicing the generator:
Always check that the fuel valve is in the OFF position and the
gasoline tank is empty.
Always check that the LPG supply hose is disconnected and
stored securely away from the generator after use.
Disconnect the spark plug wire.
WARNING
When storing the generator:
Always store away from sparks, open flames, pilot lights, heat
and other sources of ignition.
Never store generator, gasoline or LPG cylinders near
furnaces, water heaters, or any other appliances that produce
heat or have automatic ignitions.
DANGER
NEVER place a gasoline container, gasoline tank, LPG cylinder
or any combustible material in the path of the exhaust stream
during operation of the engine.
WARNING
Never use a gasoline container, gasoline tank, LPG connector
hose, LPG cylinder or any other fuel item that is broken, cut,
torn or damaged.

NOTICE
Once oil has been added, a visual check should show oil about
1-2 threads from running out of the fill hole.
When using the dipstick to check oil level, DO NOT screw in
the dipstick while checking.
NOTICE
Check oil level often during the break-in period. Refer to the
Maintenance section for recommended service intervals.
CAUTION
This engine is equipped with a low oil shut-off and will stop
when the oil level in the crankcase falls below the threshold
level.
NOTICE
The first 5 hours of run time are the break-in period for the
unit. During the break in period stay at or below 50% of the
running watt rating and vary the load occasionally to allow
stator windings to heat and cool. Adjusting the load will also
cause engine speed to vary slightly and help seat piston rings.
After the 5 hour break-in period, change the oil.
NOTICE
Synthetic oil may be used after the 5 hour initial break-in
period. Using synthetic oil does not decrease the recommended
oil change interval. Full synthetic 5W-30 oil will aid in starting
in cold ambient < 41º F (5º C) temperatures.
Add Fuel: Gasoline
DANGER
Gasoline vapors are highly flammable and extremely explosive.
DO NOT light or smoke cigarettes. Fire or explosion can cause
severe burns or death.
Only fill or drain fuel outdoors in a well-ventilated area.
DO NOT pump gasoline directly into the generator. Use an
approved container to transfer the fuel to the generator.
Never use a gasoline container, gasoline tank, or any
other fuel item that is broken, cut, torn or damaged.
DO NOT overfill the gasoline tank. Always keep fuel away from
sparks, open flames, pilot lights, heat and other sources of
ignition.
Use clean, fresh, regular unleaded gasoline with a minimum
octane rating of 87 and an ethanol content of 10% or less by
volume. ybc
DO NOT mix oil with gasoline.
1. Remove the gasoline cap.
2. Slowly add gasoline to the tank. Tank is full when gasoline
reaches red circle on screen. DO NOT OVERFILL. Gasoline can
expand after filling. A minimum of ¼ in. (6.4 mm) of space left
in the tank is required for gasoline expansion, although more
than ¼ in. (6.4 mm) is recommended. Gasoline can be forced
out of the tank as a result of expansion if overfilled, and can
affect the stable running condition of the generator.
3. The approximate fuel level is shown on the fuel gauge on top
of the fuel tank.

4. Screw on the gasoline cap and wipe away any spilled fuel.
CAUTION
Use unleaded gasoline with a minimum octane rating of 87
and an ethanol content of 10% or less by volume.
DO NOT light cigarettes or smoke when filling the tank.
DO NOT mix oil and gasoline.
DO NOT overfill the tank. Fill tank to approximately ¼ in.
(6.4 mm) below the top of the tank to allow for gasoline
expansion.
DO NOT pump gasoline directly into the generator at the pump.
Use an approved fuel container to transfer the gasoline to the
generator.
DO NOT fill tank indoors.
DO NOT fill tank when the engine is running or hot.
WARNING
Pouring gasoline too fast through the fuel screen may result
in gasoline splashing over the generator and operator while
filling.
NOTICE
The generator engine works well with 10% or less ethanol
blended gasoline. When using ethanol-gasoline blends there
are some issues worth noting:
– Ethanol-gasoline blends can absorb more water than
gasoline alone.
– These ethanol blends can eventually separate, leaving
water or a watery goo in the tank, fuel valve and
carburetor. The compromised gasoline can be drawn into
the carburetor and cause damage to the engine and/or
create potential hazards.
– If a fuel stabilizer is used, confirm that it is formulated to
work with ethanol-gasoline blends.
– Any damages or hazards caused by using ethanol blended
gasoline higher than 10% by volume, improperly stored
gasoline, and/or improperly formulated stabilizers, are not
covered by manufacturer’s warranty.
It is advisable to always shut off the gasoline supply and
run the engine to starvation after each use. See Storage
instructions for extended non-use.
Add Fuel: Propane (LPG)
DANGER
NEVER place the LPG (liquefied petroleum gas) connector hose
OR LPG cylinder tank in the path of the muffler exhaust gas
stream of the generator during engine operation.
Connecting an LPG cylinder
1. Confirm the dial is in the OFF position.
2. If using a new propane cylinder, remove the plastic cap from
the cylinder valve.
3. Attach the LPG hose assembly (included) to the propane
cylinder valve and hand tighten until snug. DO NOT OVER
TIGHTEN.
4. Remove the rubber boot covering the propane connection port
on the inverter.
5. Align the plastic finger on the male hose fitting on the LPG
hose assembly with the slot next to the female quick connect
coupling on the inverter.
6. Insert the hose fitting into the quick connect coupling and
push in until you hear a “click” and the outside collar of the
quick connect coupling moves forward.
7. Check all connections for leaks by wetting the fittings with a
solution of soap and water. Bubbles which appear or bubbles
which grow indicate that a leak exists. If a leak exists at a
fitting then turn off the valve on the cylinder and tighten the
fitting. Turn the valve back on and recheck the fitting with the
soap and water solution. If the leak continues or if the leak
is not at a fitting then do not use the generator and contact
customer service.
NOTICE
– The LPG hose included with this unit works with standard
20, 30, and 40 pound LPG tanks.
– Verify the requalification date on the cylinder has not
expired.
– Always position the cylinder so the connection between the
cylinder valve and generator inlet won’t cause sharp bends
or kinks in the LPG hose.

201177 - 8500W DUAL FUEL ELECTRIC START INVERTER GENERATOR
OPERATION
21
CAUTION
Do not allow children to tamper or play with the LPG cylinder
or hose connections.
CAUTION
Use approved LPG cylinders equipped with an OPD (overfilling
prevention device) valve. Always keep the cylinder in a vertical
position with the valve on top and installed at ground level
on a flat surface. Cylinders must not be installed near any
heat source and should not be exposed to sun, rain, and dust.
When transporting and storing, turn off the cylinder valve and
generator LPG valve, and disconnect the cylinder. Plug the
outlet, usually by a plastic protective cap, if one is available.
Keep cylinders away from heat and ventilated when in a
vehicle.
WARNING
If there is a strong smell of LPG: Close valve on the cylinder.
Check all connections for leaks by wetting the fittings with a
solution of soap and water. Bubbles which appear or bubbles
which grow indicate that a leak exists. Do not smoke or light a
cigarette, or check for leaks using a match, open flame source
or lighter. Contact a qualified technician to inspect and repair
an LPG system if a leak is found, before using the generator.
Grounding
Your generator must be properly connected to an appropriate
ground to help prevent electric shock.
WARNING
Failure to properly ground the generator can result in electric
shock.
A ground terminal connected to the panel of the generator has
been provided (see Controls and Features for terminal location).
For remote grounding, connect a length of heavy gauge
(12 AWG minimum) copper wire between the generator ground
terminal and a copper rod driven into the ground. We strongly
recommend that you consult with a qualified electrician to ensure
compliance with local electrical codes.
Neutral Floating*
– Neutral circuit IS NOT electrically connected to the frame/
ground of the generator.
– The generator (stator winding) is isolated from the frame and

including a generator compartment of a recreational vehicle.
NEVER operate or start the generator in the back of an
SUV, camper, trailer, truck bed (regular sides, flat or other
configuration), under staircases, stairwells, next to walls
or buildings or in any other location that will not allow for
adequate cooling of the generator or for the proper exit of the
exhaust flow from the muffler system.
DO NOT operate or store the generator in wet weather
conditions such as rain or snow. Using a generator in wet
conditions could result in serious injury or death due to
electrocution.
In some state’s generators may be required to be registered
with the local utility company when used at construction sites
and may be subject to additional rules and regulations, consult
your local municipal authority.
Generators should always be operated on a flat, level surface
at all times (even when not in operation).
Generators must have a minimum of 5 feet (1.5 m) of
clearance from all combustible material.
Generators must also have a minimum of 3 feet (91.4 cm)
of air flow clearance on all sides to allow for adequate
performance cooling, maintenance and servicing.
Always place the generator in a well-ventilated area. NEVER
place the generator near air intake vents or where exhaust
fumes could be drawn into occupied or confined spaces.
Always carefully consider wind and air currents when
positioning generator.
Always allow generators to properly cool before transport or
for storage purposes.
Failure to follow proper safety precautions may result in
personal injury, damage to the generator and void the
manufacturer’s warranty.
WARNING
During operation the muffler and exhaust fumes will become
hot. If adequate cooling and breathing space are not supplied,
or if the generator is blocked or enclosed, temperatures can
become extremely heated and may lead to fire.
WARNING
Do not expose to rain or use in damp locations.
Keep all objects a minimum of 5 feet (1.5m) away from the
generator at all times. Heat from the muffler surface and
exhaust gas stream can ignite combustible materials.
WARNING
If you must operate in rain or damp locations, DO NOT operate

NOTICE
Accumulation of frost on LPG cylinder and regulators is
common during operation and normally is not an indication
of a problem. As LPG vaporizes and travels from the cylinder
to the generator engine it expands. The amount of frost that
forms can be affected by the size of the cylinder, the amount
of LPG being used, the humidity of the air and other operating
conditions.
In unusual situations this frost may eventually restrict the flow
of LPG to the generator resulting in deteriorating performance.
For example, if the cylinder temperature is reduced to a very
low level then the rate at which the LPG vaporizes is also
reduced and may not provide sufficient flow to the engine. This
is not an indication of a problem with the generator but only
a problem with the flow of LPG from the cylinder. If generator
performance seems to be deteriorating at the same time that
ice formation is observed on tank valve, hose or regulator then
some actions may be taken to eliminate this symptom.
In these rare situations it can be helpful to reduce or eliminate
the cold fuel system effects by doing one of the following:
– Exchanging fuel cylinders to allow the first cylinder to
warm up, repeating as necessary.
– Placing the cylinder at the end of the generator near the
handle, where engine fan air flows out from the generator.
This air is slightly heated by flowing over the engine. The
cylinder should not be placed in the path of the muffler
outlet.
– The cylinder can be temporarily warmed by pouring warm
water over the top of the cylinder.
Battery
NOTICE
The supplied 12V battery will re-charge while the engine is
running. When the generator is not in use for extended periods
of time, it is recommended that the battery be fully charged at
least once per month with a trickle charger and disconnected
when fully charged or charged using a battery maintainer for
long term storage (not included).

201177 - 8500W DUAL FUEL ELECTRIC START INVERTER GENERATOR

Connecting Electrical Loads
Let the engine stabilize and warm up for a few minutes after
starting.
Plug in and turn on the desired 120 or 240 (if applicable) Volt AC
single phase, 60 Hz electrical loads.
– DO NOT connect 3-phase loads to the generator.
– DO NOT overload the generator.
– Use only a high quality, insulated, compatible (3-wire or
4-wire) grounded cord set rated equal to or greater (volts and
amps) than the receptacle plugging into.
WARNING
Always remember to plug your appliances directly into the
generator and do not plug the generator power cord into any
electrical outlet or connect to the circuit breaker panel in your
home. Connecting a generator to your home’s electric utility
company’s power lines, or to another power source, called
‘backfeeding’ is a dangerous practice that is illegal in many
states and municipalities.
This action if done incorrectly could damage your generator,
appliances and could cause serious injury or death to you
or a utility worker when attempting to restore power during
an outage occurrence in the neighborhood who may then
unexpectedly encounter high voltage on the utility line and
suffer a fatal shock.
Whether injuries occur or not, if installed incorrectly and not to
applicable laws and codes, you may be subject to fines or the
utility company may disconnect your home power should this
practice be found in your home.
If the generator will be connected to a building electrical
system, those connections must isolate the generator power
from the utility power. You are responsible for ensuring your
generator’s electricity does not backfeed into the electric
utility power lines. These connections must comply with all
applicable laws and codes – Consult your local utility company
or a qualified electrician to properly install this connection.
Do Not Overload Generator
Capacity
Follow these simple steps to calculate the running and starting
watts necessary for your purposes:
1. Select the electrical devices you plan on running at the same
time.
2. Total the running watts of these items. This is the amount of
power you need to keep your items running.
3. Identify the highest starting wattage of all devices identified
in step 1. Add this number to the number calculated in step 2.

GFCI
Your generator is equipped with ground fault circuit interrupter
(GFCI) receptacles. In the event of a ground fault, a GFCI trips
automatically to stop the flow of electricity and prevent serious
injury. The green indicator light (A) on the receptacle will also
turn off. Press the “RESET” (B) button located on the front of the
receptacle to restore flow of electricity. The indicator light will also
turn back on. GFCI does not protect against circuit overloads.
To ensure proper operation of the GFCI duplex, perform this test
monthly:
1. With the generator running, plug a lamp into the GFCI
receptacle. Turn the lamp on.
2. Press the “TEST” (C) button located on the front of the
receptacle to trip the device. This should immediately stop
the flow of electricity and shut off the lamp. If the electricity
is not stopped, do not use this receptacle until it has been
serviced or replaced.
3. Press the “RESET” button located on the front of the
receptacle to restore the flow of electricity. If the indicator
light does not come back on or if the GFCI cannot be reset
then it must be replaced.

NOTICE
In any electrical application, some current will flow through
the protective ground conductor to the ground, this is called
leakage current. It takes 4 mA (0.004 A) and higher of leakage
current from the hot wire to the ground to cause a GFCI to trip.
On circuits protected by GFCI’s, leakage current can cause
unnecessary and intermittent tripping.
Some stationary motors, such as a bathroom vent fan,
fluorescent lighting fixtures or some refrigerators, may produce
enough leakage to cause nuisance tripping. To avoid nuisance
tripping, a GFCI should not supply:
– Fluorescent or other types of electric-discharge lighting
fixtures.
– Permanently installed electric motors, like air conditioners,
furnaces or refrigerators.
Eco (Economy) Mode
The Eco Mode button can be activated to turn on economy control
in order to minimize fuel consumption and noise while operating
the unit during times of reduced electrical output. Eco Mode
allows the engine speed to idle during periods of non-use.
The engine speed returns to normal when an electrical load is
connected. When the economy switch is off, the engine runs at
normal speed continuously.
CAUTION
For periods of high electrical load or momentary fluctuations,
the Eco Mode should be off.

Operation at High Altitude
The density of air at high altitudes is lower than at sea level.
Engine power is reduced as the air mass and air-fuel ratio
decrease. Engine power and generator output will be reduced
approximately 3½% for every 1000 ft. of elevation above sea level.
At high altitudes increased exhaust emissions can also result due
to the increased enrichment of the air fuel ratio. Other high altitude
issues can include hard starting, increased fuel consumption and
spark plug fouling.
To alleviate high altitude issues other than the natural power
loss, CPE can provide a high altitude carburetor main jet. The
alternative main jet and installation instructions can be obtained
by contacting our Technical Support Team. Installation instructions
are also available in the Technical Bulletin area of the CPE website.
The part number and recommended altitude range for the
application of the high altitude carburetor main jet is listed in the
following table.
In order to select the correct high altitude main jet it is necessary
to identify the carburetor model. For this purpose, a code is
stamped on the side of the carburetor. Select the correct high
altitude jet part number corresponding to the carburetor code
found on your particular carburetor.
Carb. Code High Alt. Jet Part Number Altitude Range
16100-
000068
16161-000078 3000ft. (914m)
16161-000045 6000ft. (1829 m)
WARNING
Operation using the alternative main jet at elevations lower
than the recommended minimum altitude can damage the
engine. For operation at lower elevations, the originally
supplied standard main jet must be used. Operating the
engine with the wrong engine configuration at a given altitude
may increase its emissions and decrease fuel efficiency and
performance.

CHAMPION POWER EQUIPMENT, INC. (CPE)
AND THE UNITED STATES ENVIRONMENTAL PROTECTION AGENCY (U.S. EPA)
EMISSION CONTROL SYSTEM WARRANTY
Your Champion Power Equipment (CPE) engine complies with U.S. EPA emissions regulations.
YOUR WARRANTY RIGHTS AND OBLIGATIONS:
The US EPA and CPE are pleased to explain the Federal Emission Control Systems Warranty on your 2024 small off-road engine (SORE)
and engine powered equipment. New engines and equipment must be designed, built and equipped, at the time of sale, to meet U.S.
EPA regulations for small off-road engines (SORE). CPE warrants the emission control system on your small off-road engine (SORE)
and equipment for the period of time listed below, provided there has been no abuse, neglect, unapproved modification, or improper
maintenance of your equipment.
Your emission control system may include parts such as the carburetor, fuel-injection system, the ignition system, catalytic converter and
fuel lines. Also included may be hoses, belts, connectors and other emission related assemblies. Where a warrantable condition exits, CPE
will repair your small off-road engine (SORE) at no cost to you including diagnosis, parts and labor.
MANUFACTURER’S EMISSION CONTROL SYSTEM WARRANTY COVERAGE:
This emission control system is warranted for two years, subject to provisions set forth below. If, during the warranty period, an emission
related part on your engine is defective in materials or workmanship, the part will be repaired or replaced by CPE.
OWNER WARRANTY RESPONSIBILITIES:
As the small off-road engine (SORE) owner, you are responsible for the performance of the required maintenance listed in your Owner’s
Manual. CPE recommends that you retain all your receipts covering maintenance on your small off-road engine, but CPE cannot deny
warranty solely for the lack of receipts or for your failure to ensure the performance of all scheduled maintenance.
As the small off-road engine (SORE) owner, you should however be aware that CPE may deny you warranty coverage if your small, off-road
engine (SORE) or a part has failed due to abuse, neglect, improper maintenance or unapproved modifications.
You are responsible for presenting your small off-road engine (SORE) to an Authorized CPE service outlet or alternate service outlet as
described in (3)(f.) below, CPE dealer or CPE, Las Vegas, NV. as soon as a problem exists. The warranty repairs should be completed in a
reasonable amount of time, not to exceed 30 days.
If you have any questions regarding your warranty rights and responsibilities, you should contact:

EMISSION CONTROL SYSTEM WARRANTY
The following are specific provisions relative to your Emission Control System (ECS) Warranty Coverage.
1. APPLICABILITY: This warranty shall apply to 1997 and later model year small off-road engines (SORE). The ECS Warranty Period shall
begin on the date the new engine or equipment is delivered to its original, end-use purchaser, and shall continue for 24 consecutive
months thereafter.
2. GENERAL EMISSIONS WARRANTY COVERAGE
CPE warrants to the original, end-use purchaser of the new engine or equipment and to each subsequent purchaser that each of its
small off-road engines (SORE) is:
2a. Designed, built and equipped so as to conform to U.S. EPA emissions standards for spark-ignited engines at or below 19 kilowatts.
2b. Free from defects in materials and workmanship that cause the failure of a warranted part to be identical in all material respects
to the part as described in the engine manufacturer’s application for certification for a period of two years.
3. THE WARRANTY ON EMISSION-RELATED PARTS WILL BE INTERPRETED AS FOLLOWS:
3a. Any warranted part that is not scheduled for replacement as required maintenance in the Owners Manual shall be warranted for
the ECS Warranty Period. If any such part fails during the ECS Warranty Period, it shall be repaired or replaced by CPE according
to Subsection “d” below. Any such part repaired or replaced under the ECS Warranty shall be warranted for any remainder of the
ECS Warranty Period.
3b. Any warranted, emissions-related part which is scheduled only for regular inspection as specified in the Owners Manual shall be
warranted for the ECS Warranty Period. A statement in such written instructions to the effect of “repair or replace as necessary”,
shall not reduce the ECS Warranty Period. Any such part repaired or replaced under the ECS Warranty shall be warranted for the
remainder of the ECS Warranty Period.
3c. Any warranted, emissions-related part which is scheduled for replacement as required maintenance in the Owner’s Manual shall
be warranted for the period of time prior to the first scheduled replacement point for that part. If the part fails prior to the first
scheduled replacement, the part shall be repaired or replaced by CPE according to Subsection “d” below. Any such emissions-
related part repaired or replaced under the ECS Warranty, shall be warranted for the remainder of the ECS Warranty Period prior to
the first scheduled replacement point for such emissions-related part.
3d. Repair or replacement of any warranted, emissions-related part under this ECS Warranty shall be performed at no charge to the
owner at a CPE Authorized Service Outlet.
3e. The owner shall not be charged for diagnostic labor which leads to the determination that a part covered by the ECS Warranty is in
fact defective, provided that such diagnostic work is performed at a CPE Authorized Service Outlet.
3f. CPE shall pay for covered emissions warranty repairs at non-authorized service outlets under the following circumstances:
i. The service is required in a population center with a population over 100,000 according to U.S. Census 2000 without a CPE
Authorized Service Outlet AND
ii. The service is required more than 100 miles from a CPE Authorized Service Outlet. The 100 mile limitation does not apply in the
following states: Alaska, Arizona, Colorado, Hawaii, Idaho, Montana, Nebraska, Nevada, New Mexico, Oregon, Texas, Utah and
Wyoming.
3g. CPE shall be liable for damages to other original engine components or approved modifications proximately caused by a failure
under warranty of an emission-related part covered by the ECS Warranty.
3h. Throughout the ECS Warranty Period, CPE shall maintain a supply of warranted emission-related parts sufficient to meet the
expected demand for such emission-related parts.
3i. Any CPE Authorized and approved emission-related replacement part may be used in the performance of any ECS Warranty
maintenance or repair and will be provided without charge to the owner. Such use shall not reduce CPE’s warranty obligation.
3j. Unapproved add-on or modified parts may not be used to modify or repair a CPE engine. Such use voids this ECS Warranty and
shall be sufficient grounds for disallowing an ECS Warranty claim. CPE shall not be liable hereunder for failures of any warranted
parts of a CPE engine caused by the use of such an unapproved add-on or modified part.

sell and service that CPE product during his normal business hours. Alternate service locations defined in Section (3)(f.) above must be
