1. Location
DANGER! Engine exhaust contains carbon monoxide, a poisonous gas that could kill
you in minutes. You CANNOT smell it, see it, or taste it. Even if you do not smell exhaust
fumes, you could still be exposed to carbon monoxide gas.
Carbon Monoxide Alarm(s)
Install carbon monoxide alarms inside your home. Without working
carbon monoxide alarms, you will not realize you are getting sick and
dying from carbon monoxide poisoning.
20 ft. (6 m) min.
OPERATION
Install battery-operated carbon monoxide alarms or plug-in carbon monoxide alarms with
battery back-up according to the manufacturer's instructions. Smoke alarms cannot detect
carbon monoxide gas.
Do not run this log splitter inside homes, garages, basements, crawlspaces, sheds, or other
partially enclosed spaces even if using fans or opening doors and windows for ventilation.
Carbon monoxide can quickly build up in these spaces and can linger for hours, even after this
product has shut off.
If you start to feel sick, dizzy, weak or your home’s carbon monoxide alarm sounds, get to fresh air
right away. Call emergency services. You may have carbon monoxide poisoning.
Prevent Carbon Monoxide (CO) Poisoning
Use outdoors and downwind at least 20 ft. (6 m) from any home.
Point exhaust away from all homes and occupied spaces.
Install CO alarms inside your home.
Operate log splitter only outdoors and downwind at least 20 ft.(6 m) from occupied spaces with
exhaust pointed away to reduce the risk of carbon monoxide accumulating.

4. Using oil funnel, slowly pour contents of provided oil bottle into oil fill opening until oil reaches
upper limit "H" mark on the dipstick. Be careful not to overfill. Overfilling could cause engine
starting problems or engine damage.
5.Replace oil fill cap/dipstick and fully tighten.
6.Oil level should be checked prior to each use or at least every 8 hours of operation. Keep oil
level maintained.
The log splitter is equipped with a low oil shutdown. If the oil level drops below the minimum
required level, a sensor will activate an internal switch stopping the engine. If the engine shuts off
and the oil level is within specifications, check to see if log splitter is sitting at an angle. Place log

Operation at High Altitude
At altitudes over 5,000 feet (1524 meters), a minimum 85 octane gasoline is acceptable. Engine power
will be reduced approximately 3.5% for every 1000 feet (305 m) of elevation above sea level. High
altitude may cause hard starting, increased fuel consumption and spark plug fouling. To operate at
high altitudes FIRMAN can provide a high altitude carburetor main jet. The alternative main jet and
installation instructions can be obtained by contacting Customer Support.
NOTICE Operation using an alternative main jet at elevations lower than the recommended
minimum altitude can damage the engine. For operation at lower elevations, the standard main
jet supplied must be used. Operating the engine with the wrong main jet may increase exhaust
emissions, fuel consumption and reduce performance.

Long Term Storage
Do not store fuel near any ignition sources.
When draining fuel move pump outdoors and use a commercially available non-conductive
vacuum siphon. Fuel must be drained into an approved container.
WARNING! Fuel and its vapors are extremely flammable which could cause burns
or fire resulting in death or serious injury.
If the log splitter will not be used for more than 30 days, prepare it for long term storage as follows:
1. Retract the wedge to protect the rod from corrosion.The rod should be retracted after every use.
2. Never store the machine with fuel in the fuel tank inside a building where ignition sources are
present.
3. Drain all fuel completely from the tank, fuel line and carburetor to prevent gum from forming.
If log splitter is stored with fuel in the fuel tank, we recommend using a gas stabilizer to prevent
sediment from gumming up the carburetor. If there is dirt or moisture in the fuel, drain the fuel
tank. Completely fill the tank with fresh, unleaded gas and add the appropriate amount of fuel
stabilizer. Run the engine for a short time to allow the stabilizer to circulate.
4. Before storing the log splitter, stop the engine, wait at least five minutes to allow all parts to cool.
5. Change the engine oil.
6. Remove the spark plug and pour about ½ ounce (14.8 ml) of oil into the cylinder. Pull the engine
recoil slowly to distribute the oil and lubricate the cylinder. Reinstall the spark plug.
NOTICE The use of a pressure washer or a garden hose to clean the log splitter is not recommended.
The use of water will result in corrosion, shortening life and reducing serviceability.
7. Check the wedge slide for nicks and wear. Sharpen if needed.
8. Apply a rust preventative (oil film or equivalent) to any bare metal areas on the wedge slide and
on top of the beam.
9. Using a soft bristle brush, clean the exterior of the unit removing all dirt, grease, or other foreign
material. Remove dirt and debris from the cylinder head cooling fins and muffler area.
10. To prevent rust, touch up painted surfaces if scratched or chipped.
11. Be sure all hoses, nuts, bolts, and screws are securely fastened.
12. Store the log splitter in a dry, protected place. If it is necessary to store outside, cover it with a
tarp of similar protective material (especially the Engine). Avoid storage near corrosive materials.

EMISSION CONTROL WARRANTY STATEMENT
MANUFACTURER'S WARRANTY COVERAGE:
OWNER'S WARRANTY RESPONSIBILITIES:
This emission Control System is warranted for two years. If any emission-related part on your
engine/equipment is defective, the part will be repaired or replaced by FIRMAN.
As the small off-road engine/equipment owner, you are responsible for the performance of the
required maintenance listed in your owner's manual. FIRMAN recommends that you retain all
receipts covering maintenance on your small off-road engine/equipment, but FIRMAN cannot
deny warranty coverage solely for the lack of receipts or for your failure to ensure the performance
of all scheduled maintenance. As the small off-road engine/equipment owner, you should
however be aware that FIRMAN may deny you warranty coverage if your small off-road
engine/equipment or a part has failed due to abuse, neglect, improper maintenance or
unapproved modifications. You are responsible for presenting your small off-road
engine/equipment to FIRMAN distribution center as soon as a problem exists. The warranty
repairs shall 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 FIRMAN at
1-844-347-6261 or www.firmanpowerequipment.com .
DEFECTS WARRANTY REQUIREMENTS:
(a) The warranty period begins on the date the engine/equipment is delivered to an ultimate
purchaser.
(b) General Emissions Warranty Coverage. FIRMAN warrants to the ultimate purchaser and each
subsequent owner that the engine/equipment is:
(1) Designed, built, and equipped so as to conform with all applicable regulations adopted by the
Environmental Protection Agency; and
(2) Free from defects in materials and workmanship that causes the failure of a warranted part for
a period of two years.
(c) The warranty on emissions-related parts will be interpreted as follows:
(1) Any warranted part that is not scheduled for replacement as required maintenance in the
written instructions required by subsection (d) must be warranted for the warranty period
defined in Subsection (b)(2). If any such part fails during the period of warranty coverage, it
must be repaired or replaced by FIRMAN according to Subsection (4) below. Any such part
repaired or replaced under the warranty must be warranted for the remaining warranty period.
(2) Any warranted part that is scheduled only for regular inspection in the written instructions
required by subsection (d) must be warranted for the warranty period defined in Subsection (b)(2).
A statement in such written instructions to the effect of “repair or replace as necessary” will
not reduce the period of warranty coverage. Any such part repaired or replaced under warranty
must be warranted for the remaining warranty period.
YOUR WARRANTY RIGHTS AND OBLIGATIONS
The United States Environmental Protection Agency (EPA) and FIRMAN POWER EQUIPMENT INC.
(FIRMAN) are pleased to explain the emission control system warranty on your [2026-2027] model
year small off-road engine/equipment. In the United States, new small off-road engine/equipment
must be designed, built and equipped to meet the State's stringent anti smog standards. FIRMAN
must warrant the emission control system on your small off-road engine/equipment for the period
listed below provided there has been no abuse, neglect or improper maintenance of your small
off-road engine/equipment leading to the failure of the emission control system. Your emissions
control system may include parts such as the carburetor or fuel-injection system, the ignition
system, catalytic converter, fuel tanks, fuel lines (for liquid fuel and fuel vapors), fuel caps, valves,
canisters, filters, clamps and other associated components. Also included may be hoses, belts,
