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.

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
splitter on an even surface to correct this. If engine fails to start, the oil level may not be high enough
to deactivate the internal low oil level switch. Make sure the sump is completely full of oil to the
upper limit (H). Do not operate engine until oil level issue is corrected. Contact FIRMAN customer
service.

3. Install fuel cap and let any spilled fuel evaporate before starting engine.
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.

High fluid pressure and temperatures are created in the hydraulic log splitter. Hydraulic fluid will
escape through a pin-size hole opening and can puncture skin and cause severe blood poisoning.
Inspect hydraulic system regularly for possible leaks. Never check for leaks with your hand while
the system is pressurized. Seek medical attention immediately if injured by escaping fluid.
Make sure all fittings are tight and secure before applying pressure. Relieve system pressure
before servicing.
Make sure the hydraulic hoses do not touch any hot surfaces or cutting areas.
Hoses need to be positioned were they are clear from the engine and cutting wedge. To avoid
death or serious injury always inspect the hoses before operating the log splitter.
WARNING! Failure to follow these instructions could result in death or serious injury.
DO NOT remove the hydraulic oil vent cap (52) when the engine is running or oil is hot. Hot oil can
escape causing severe burns. Always allow the log splitter to cool completely before removing the
hydraulic oil vent cap.

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.

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

(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).

must be warranted for the remaining warranty period.

repairs and must be provided without charge to the owner. Such use will not reduce the
warranty obligations of FIRMAN.

may not be used. The use of any non-exempted add-on or modified parts will be grounds for
disallowing a warranty claim. FIRMAN will not be liable to warrant failures of warranted parts
caused by the use of a non-exempted add-on or modified part.
