Keep long hair away from engine and air intake. Retain hair with cap or net.
Heavy protective clothing can increase operator fatigue, which may lead to
heat stroke. Schedule heavy work for early morning or late afternoon hours
when temperatures are cooler.
The components of this machine generate an electromagnetic
field during operation, which may interfere with some
pacemakers. To reduce the risk of serious or fatal injury,
persons with pacemakers should consult with their physician
and the pacemaker manufacturer before operating this
machine. In the absence of such information, ECHO
does not
recommend the use of this machine by anyone who has a
pacemaker.
Extended Operation / Extreme Conditions
Prolonged exposure to cold and/or vibration may result in
injury. Read and follow all safety and operation instructions to
minimize risk of injury. Failure to follow instructions may result
in painful wrist/hand/arm injuries.
It is believed that a condition called Raynaud’s Phenomenon, which affects
the fingers of certain individuals, may be brought about by exposure to
vibration and cold. Exposure to vibration and cold may cause tingling and
burning sensations, followed by loss of color and numbness in the fingers.
The following precautions are strongly recommended, because the
minimum exposure, which might trigger the ailment, is unknown.
• Keep your body warm, especially the head, neck, feet, ankles, hands, and
wrists.
• Maintain good blood circulation by performing vigorous arm exercises
during frequent work breaks, and also by not smoking.
• Limit the hours of operation. Try to fill each day with jobs where operating
the unit or other hand-held power equipment is not required.
• If you experience discomfort, redness, and swelling of the fingers followed
by whitening and loss of feeling, consult your physician before further
exposing yourself to cold and vibration.
SAFETY PB-2620
10 X7501190601

Repetitive Stress Injuries (RSI)
It is believed that overusing the
muscles and tendons of the fingers,
hands, arms, and shoulders may
cause soreness, swelling,
numbness, weakness, and extreme
pain in those areas. Certain
repetitive hand activities may put
you at a high risk for developing a
Repetitive Stress Injury (RSI). An
extreme RSI condition is Carpal
Tunnel Syndrome (CTS), which
could occur when your wrist swells
and squeezes a vital nerve that runs
through the area. Some believe that
prolonged exposure to vibration may
contribute to CTS. CTS can cause
severe pain for months or even
years.
To reduce the risk of RSI/CTS, do
the following:
• Avoid using your wrist in a bent, extended, or twisted position. Instead try
to maintain a straight wrist position. Also, when grasping, use your whole
hand, not just the thumb and index finger.
• Take periodic breaks to minimize repetition and rest your hands.
• Reduce the speed and force with which you do the repetitive movement.
• Do exercises to strengthen the hand and arm muscles.
• Immediately stop using all power equipment and consult a doctor if you
feel tingling, numbness, or pain in the fingers, hands, wrists, or arms. The
sooner RSI/CTS is diagnosed, the more likely permanent nerve and
muscle damage can be prevented.
All over head electrical conductors and communications wires
can have electricity flow with high voltages. This unit is not
insulated against electrical current. Never touch wires directly
or indirectly, otherwise serious injury or death may result.

Fuel
Diesel fuels and alternative fuels, such as E-15 (15% ethanol),
E
-85 (85% ethanol) or any fuels not meeting ECHO
requirements are NOT approved for use in ECHO 2-stroke
gasoline engines. Use of diesel or alternative fuels may cause
performance problems, loss of power, overheating, fuel vapor
lock, and unintended machine operation, including, but not
limited to, improper clutch engagement. Diesel or alternative
fuels may also cause premature deterioration of fuel lines,
gaskets, carburetors and other engine components.
PB-2620 OPERATION
X7501190601 19
© 11/2018 ECHO Inc.
Fuel Requirements
Gasoline - Use 89 Octane [R+M/2] (mid grade or higher) gasoline known to
be good quality. Gasoline may contain up to 10% Ethanol (grain alcohol) or
15% MTBE (methyl tertiary-butyl ether). Gasoline containing methanol
(wood alcohol) is NOT approved. Use of ECHO branded fuel is
recommended to extend engine life in all air-cooled 2-stroke and 2/4-stroke
hybrid engines.
Two Stroke Oil - A two-stroke engine oil, such as ECHO branded 2-stroke
oils, meeting ISO-L-EGD (ISO/CD 13738) and J.A.S.O.
FD Standards must
be used. ECHO branded 2-stroke oils meet these standards. Engine
problems due to inadequate lubrication caused by failure to use an ISO-L-
EGD (ISO/CD 13738) and J.A.S.O. M345-
FD certified oil will void the two-
stroke engine warranty.
2-Stroke engine oil contains petroleum distillates and other
additives that may be harmful if swallowed. Heated oil can
release vapors that can cause flash fire, or ignite with explosive
force. Read and follow the oil manufacturer’s instructions, and
observe all safety warnings and precautions for handling
flammable liquids. For more detailed safety and first aid
information, visit www.echo-usa.com for a copy of the Material
Safety Data Sheet.
◆ KEEP OUT OF REACH OF CHILDREN.
◆ If swallowed, do not induce vomiting. CALL PHYSICIAN OR
A POISON CONTROL CENTER IMMEDIATELY.
◆ WEAR SAFETY GLASSES when mixing or handling.
◆ AVOID repeated or prolonged skin contact
◆ AVOID inhaling oil mists or vapors.
ECHO branded 2-stroke oils may be mixed at 50:1 ratio for
application in all ECHO engines sold in the past regardless of ratio
specified in those manuals.
Handling Fuel
Fuel is VERY flammable. Use extreme care when mixing, storing
or handling, or serious personal injury may result.
OPERATION PB-2620
20 X7501190601
© 11/2018 ECHO Inc.
◆ Use an approved fuel container. Mark fuel containers as
containing 2-stroke mixture fuel.
◆ DO NOT smoke near fuel.
◆ DO NOT allow flames or sparks near fuel.
◆ Fuel tanks/cans may be under pressure. Always loosen
fuel caps slowly allowing pressure to equalize.
◆ NEVER refuel a unit when the engine is HOT or RUNNING!
◆ DO NOT fill fuel tanks indoors. ALWAYS fill fuel tanks
outdoors over bare ground.
◆ DO NOT overfill fuel tank. Wipe up spills immediately.
◆ Securely tighten fuel tank cap and close fuel container
after refueling.
◆ Inspect for fuel leakage. If fuel leakage is found, do not
start or operate unit until leakage is repaired.
◆ Move at least 3 m (10 ft.) from refueling location before
starting the engine.
Gasoline vapor is heavier than air, and can travel along the
ground to nearby sources of ignition such as electrical motors,
pilot lights, and hot or running engines. Vapors ignited by an
ignition source can flash back to the fuel container, resulting in
an explosion, fire, serious or fatal injuries, and extensive
property damage.
Mixing Instructions
1. Fill an approved fuel container
with half of the required
amount of gasoline.
2. Add the proper amount of
2-stroke oil to gasoline.
3. Close container and shake to
mix oil with gasoline.
4. Add remaining gasoline, close
fuel container, and remix.
Spilled fuel is a leading cause of hydrocarbon emissions. Some
states may require the use of automatic fuel shut-off containers to
reduce fuel spillage.

Use reduced speed only when
performing light-duty tasks or to
comply with local noise
regulations. Continuous low
speed operation may allow fuel/oil
residue to build-up on the piston
and cause rapid build-up of
carbon on the spark arrestor
screen, resulting in overheating
and engine damage. To reduce
harmful build-up, run engine at
wide open throttle for at least 5 minutes every hour, and inspect/clean
the spark arrestor screen after approximately 40 hours of operation.
Read the Safety Section carefully.
To avoid engine damage due to over-revving, do not block blower
pipe.
1. Use only during appropriate hours.

Keep hands, clothing and loose objects away from all openings.
Always stop engine, disconnect spark plug, and make sure all
moving parts have come to a complete stop before removing
obstructions, clearing debris, or servicing unit. Allow unit to
cool before performing service. Wear gloves to protect hands
from sharp edges and hot surfaces.
Operating a poorly maintained unit can result in serious injuries
to operator or bystanders. Always follow all maintenance
instructions as written, otherwise serious personal injury may
result.
Your unit is designed to provide many hours of trouble free service. Regular
scheduled maintenance will help your unit achieve that goal. If you are
unsure or are not equipped with the necessary tools, we recommend that
you take your unit to a Servicing Dealer for maintenance. To help you decide
whether you want to DO-IT-YOURSELF or have the Dealer do it, each
maintenance task has been graded. If the task is not listed, see your Dealer
for repairs.
Skill Levels
Level 1 = Easy to do. Common tools may be required.
Level 2 = Moderate difficulty. Some specialized tools may be required.
Level 3 = See your dealer.

1. Close choke (COLD START
[
] position). This prevents
dirt from entering the carburetor
throat when the air filter is
removed. Brush accumulated
dirt from air cleaner area.
2. Remove air filter cover. Brush
dirt from inside cover.
3. Remove air filter and lightly brush debris from filter. Replace filter if it is
damaged, fuel soaked, very dirty, or the rubber sealing edges are
deformed. Clean the filter with a neutral detergent. Do not use solvents
for cleaning.
4. If filter can be reused, be certain:
• The entire frame of the filter is securely seated in the housing.
• It is installed with the original side out.
5. Install air filter cover.
Fuel Filter
Level 1.
Fuel is VERY flammable. Use extreme care when mixing, storing
or handling, or serious personal injury may result.
1. Use a clean rag to remove
loose dirt from around fuel cap
and empty fuel tank.
2. Pull the fuel line and filter from
the tank.
3. Remove the filter from the line
and install the new filter.

Note: Federal EPA regulations require all model year 2012 and later
gasoline powered engines produced for sale in the United
States to be equipped with a special low permeation fuel
supply hose between the carburetor and fuel tank. When
servicing model year 2012 and later equipment, only fuel
supply hoses certified by EPA can be used to replace the
original equipment supply hose. Fines up to $37,500 may be
enforced for using an un-certified replacement part.
Spark Plug
Level 2.
Use only NGK BPMR8Y spark plug otherwise severe engine damage
may occur.
1. Remove spark plug and check
for fouling, worn and rounded
center electrode.
2. Clean the plug or replace with a
new one. DO NOT sand blast to
clean. Remaining sand will
damage engine.
3. Adjust spark plug gap by
bending outer electrode.
4. Tighten spark plug to 150-170 kgf • cm (130-150 in • lbf).
Cooling System
Level 2.
To maintain proper engine operating temperatures, cooling air must
pass freely through the cylinder fin area. This flow of air carries
combustion heat away from the engine.
Parts Required: Tune-Up Kit
0.65 mm (0.026 in.)
PB-2620 MAINTENANCE
X7501190601 31

Overheating and engine seizure can
occur when:
• Air intakes are blocked,
preventing cooling air from
reaching the cylinder.
• Dust and grass build up on the
outside of the cylinder. This build
up insulates the engine and
prevents the heat from leaving.
Removal of cooling passage
blockages or cleaning of cooling fins
is considered “Normal
Maintenance.” Any failure attributed
to lack of maintenance is not
warranted.
Cleaning Grill
1. Brush accumulated debris from
crankcase intake grill (A) and
discharge grill (B).

Exhaust System
See your dealer for maintenance.
Carburetor Adjustment
Engine Break-In
New engines must be operated a
minimum duration of two tanks of
fuel break-in before carburetor
adjustments can be made. During the break-in period your engine
performance will increase and exhaust emissions will stabilize. Idle speed
can be adjusted as required.
High Altitude Operation
This engine has been factory adjusted to maintain satisfactory starting and
durability performance up to 335 m (1100 ft.) above sea level (ASL) (96.0
kPa). To maintain proper engine operation above 335 m (1100 ft.) ASL the
carburetor
may need to be adjusted by an authorized ECHO service dealer.
If the engine is adjusted for operation above 335 m (1100 ft.) ASL, the
carburetor must be re-adjusted when operating the engine below
335
m (1100 ft.) ASL, otherwise severe engine damage may result.
Level 2.
Note: Every unit is run at the factory and the carburetor is set in
compliance with emission regulations. Carburetor
adjustments, other than idle speed, must be performed by an
authorized ECHO dealer.
Before adjustment make sure that:
• Air filter is clean and properly installed.
• Spark arrestor screen is free of carbon.
• Blower pipes are installed.
1. Start engine, run at idle for one minute.

2. Complete warm up by running at full throttle for 5 minutes, operating
choke twice to clear air from carburetor chambers.
3. Check idle speed and reset if
necessary. If a tachometer is
available, idle speed screw (A)
should be set to the
specifications found on
“Specifications” Page of this
manual. Turn idle screw (A)
clockwise to increase idle
speed; counter clockwise to
decrease idle speed.
