InspectYour Machine
Check your machine before starting it. Keep guards in place and in working order.
Make sure all nuts, bolts, etc., are securely tightened.
Never operate the machine when it is in need of repair or is in poor mechanical con-
dition. Replace damaged, missing, or failed parts before using it. Check for fuel leaks.
Keep the machine in safe working condition.
Do not use the machine if the engine’s switch does not turn it on or off. Any gasoline
powered machine that can’t be controlled with the engine switch is dangerous and
must be replaced.
Regularly check to see that keys and adjusting wrenches are removed from the ma-
chine area before starting it. A wrench or a key that is left attached to a rotating part
of the machine may result in personal injury.
Avoid accidental starting. Be sure the engine's switch is off before transporting the
machine or performing any maintenance or service on the unit.Transporting or per-
forming maintenance or service on a machine with its switch on invites accidents.
If the machine should start to vibrate abnormally, stop the engine (motor) and check
immediately for the cause. Vibration is generally a warning sign of trouble.
Engine Safety
This machine is equipped with an internal combustion engine. Do not use on or near
any unimproved, forest covered, or brush covered land unless the exhaust system is
equipped with a spark arrester meeting applicable local, state, or federal laws.
In the state of California, a spark arrester is required by law. Other states have similar
laws. A spark arrester, if used, must be maintained in effective working order by the
operator.
Never start or run the engine inside a closed area.The exhaust fumes are dangerous,
containing carbon monoxide, an odorless and deadly gas. Operate this unit only in
a well ventilated outdoor area.

8
5240-552
Do not tamper with the engine to run it at excessive speeds. The maximum engine
speed is preset by the manufacturer and is within safety limits. See engine manual.
Keep a Class B fire extinguisher on hand when operating this log splitter in dry areas
as a precautionary measure.
Fuel Safety
Fuel is highly flammable, and its vapors can explode if ignited. Take precautions
when using to reduce the chance of serious personal injury.
When refilling or draining the fuel tank, use an approved fuel storage container
while in a clean, well-ventilated outdoor area. Do not smoke, or allow sparks, open
flames, or other sources of ignition near the area while adding fuel or operating the
unit. Never fill the fuel tank indoors.
Keep grounded conductive objects, such as tools, away from exposed, live electrical
parts and connections to avoid sparking or arcing. These events could ignite fumes
or vapors.
Always stop the engine and allow it to cool before filling the fuel tank. Never remove
the cap of the fuel tank or add fuel while the engine is running or when the engine is
hot. Do not operate the machine with known leaks in the fuel system.
Loosen the fuel tank cap slowly to relieve any pressure in the tank.
Never overfill the fuel tank. Fill the tank to no more than 1/2” below the bottom of
the filler neck to provide space for expansion as the heat of the engine can cause
fuel to expand.
Replace all fuel tank and container caps securely and wipe up spilled fuel. Never
operate the unit without the fuel cap securely in place.
Avoid creating a source of ignition for spilled fuel. If fuel is spilled, do not attempt
to start the engine but move the machine away from the area of spillage and avoid
creating any source of ignition until fuel vapors have dissipated.
When fuel is spilled on yourself or your clothes, wash your skin and change clothes
immediately.
Store fuel in containers specifically designed and approved for this purpose.
Store fuel in a cool, well-ventilated area, safely away from sparks, open flames, or
other sources of ignition.
Never store fuel or a machine with fuel in the tank inside a building where fumes
may reach a spark, open flame, or any other source of ignition, such as a water
heater, furnace, or clothes dryer. Allow the engine to cool before storing in any en-
closure.

Hydraulic System Safety
The hydraulic system of the machine requires careful inspection along with the me-
chanical parts. Be sure to replace frayed, kinked, cracked, or otherwise damaged
hydraulic hoses or hydraulic components.
Hydraulic fluid can result in severe burns. Fluid in the hydraulic system can pene-
trate skin and result in serious injury or death. Be sure to stop the engine and relieve
hydraulic pressure before doing any work on hydraulic parts.
Keep body and hands away from pin holes or nozzles that expel hydraulic fluid when
under pressure. Use paper or cardboard, not hands, to search for leaks.
Ensure all hydraulic fluid connections are tight and all hydraulic hoses and lines are
in good condition before applying pressure to the system.
Do not remove the cap from the hydraulic tank or reservoir while the machine is running.
The tank could contain hot oil under pressure, which could result in serious injury.
Do not adjust the pressure setting on the hydraulic pump or valve.
If injured by escaping fluid, no matter how small the wound is, see a doctor at once.
A typical injection injury may be a small wound that does not look serious. However,
severe infection or reaction can result if proper medical treatment is not adminis-
tered immediately by a doctor who is familiar with injection injuries.
SPECIFIC SAFETY RULES
Preparation Of The Log
Both ends of the log should be cut as square as possible to prevent the log from
rotating out of the splitter during operation.
Never split logs greater than the specified log capacity.
Do not operate the log splitter on icy, wet, muddy, or slippery ground. Only operate
your log splitter on level ground.
Operating on a slope could cause the log splitter to roll over or logs to fall off the
equipment, which could result in injury.
Do not move the log splitter over hilly or uneven terrain without a tow
vehicle or adequate help.
Keep the work area free of clutter. Remove split wood from around the log splitter
immediately after each use to avoid potential tripping.

Machine Use And Care
Never operate the machine without good visibility or light.
Never attempt to split wood across the grain. The log splitter was not designed for
cross-grain splitting.
Always block the front and back of both wheels to prevent unintended movement.
Hold the bark side of the logs when loading or positioning, never the ends. Never
place your hands or any part of your body between a log and any part of the log
splitter.
Do not straddle or step over the log splitter during operation.
Do not reach or bend over the log splitter to pick up a log.
When stabilizing a log with the left hand, remove your hand when the wedge con-
tacts the log or serious injury may occur.
Never attempt to split more than one log at a time.
Do not attempt to load your log splitter when the ram or wedge is in motion.
Use your hand to operate the control lever on the valve. Do not use your foot, a rope,
or any extension device.
Do not move the log splitter while the engine is running.
Towing Safety
Check all local and state regulations regarding towing, licensing, and lights before
towing your log splitter.
Before towing the log splitter, check tires for excessive wear, cuts, or damage. Check
for proper tire inflation. Add air as required. Do not over inflate tires. Serious injury
can result if tires explode.
Check before towing to make sure the log splitter is correctly and securely attached
to the towing vehicle and the safety chains are secured to the hitch or bumper of the
vehicle with enough slack to allow turning. Always use a class I, 2" ball with this log
splitter.
Make sure the coupler is tight before towing and after towing 80 km (50 miles).
Never transport cargo on the log splitter. Never allow anyone to ride or sit on the
log splitter.
Always stop the engine, lock the beam in the horizontal position, and close the fuel
shut-off valve when transporting the unit.

12
5240-552
Use extra care when towing the log splitter. Do not exceed 70 km/h (45 mp/h). Tow-
ing the log splitter at a speed greater than 70 km/h (45 mp/h) could result in loss of
control, damage to the equipment, serious injury, or death.
Avoid sharp turns and steep angles. Avoid large holes or ditches when towing the
equipment. Always be careful when backing up with your log splitter when towing; it
could jackknife. Use caution when backing up; a spotter outside the vehicle is highly
recommended. Disconnect the log splitter from the towing vehicle before operating it.
