RULES FOR SAFE OPERATION
THIS SYMBOL POINTS OUT IMPORTANT SAFETY INSTRUCTIONS WHICH, IF NOT FOLLOWED, COULD ENDANGER THE
PERSONAL SAFETY AND/OR PROPERTY OF YOURSELF AND OTHERS. READ AND FOLLOW ALL INSTRUCTIONS IN THIS MANUAL BEFORE
ATTEMPTING TO OPERATE YOUR LOG SPLITTER. FAILURE TO COMPLY WITH THESE INSTRUCTIONS MAY RESULT IN PERSONAL INJURY.
WHEN YOU SEE THIS SYMBOL
Your log splitter was built to be operated according to the rules for safe operation in this
manual. As with any type of power equipment, carelessness or error on the part of the
operator can result in serious injury. If you violate any of these rules, you may cause
serious injury to yourself or others.
- A HEED ITS WARNING.
DANGER
A
TRAINING
A
1. Before operating this splitter, read and understand this
manual completely. Become familiar with it for your own
safety To fail to do so may cause serious injury. Do not
allow anyone to operate your splitter who has not read
this manual. Keep this manual in a safe place for future
and regular reference and for ordering replacement parts.
2. Never use your splitter for any other purpose than
splitting wood. It is designed for this use and any other
use may cause an injury. Your log splitter is a precision
piece of power equipment, not a playtoy. Therefore,
exercise extreme caution at all times.
Never allow children to operate your log splitter. Do not
^ allow adults to operate it without proper instruction.
Only persons well acquainted with these rules of safe
operation should be allowed to use your log splitter.
4. Only the operator is to be near your log splitter during use.
Keep all others, including pets and children, a minimum
of 20 feet away from your work zone. Flying wood can
be hazardous. If a helper is assisting in loading logs, never
activate the control until the helper is clear of the area.
More accidents occur when more than one person
operates the log splitter than at any other time.
5. No one should operate this unit while intoxicated or while
taking medication that impairs the senses or reactions.
A clear mind is essential for safety. Never allow a
person who is tired or otherwise not alert to use your
splitter.
Never operate your splitter on slippery, wet muddy or icy
surfaces. Safe footing is essential in preventing accidents.
Never operate your splitter while attached to a towing
vehicle.
Only operate your splitter on level ground and not on the
side of a hill. It could tip, or rolling logs or poor footing
could cause an accident. Operating the splitter on level
ground also prevents the spillage of gasoline from the
fuel tank.
9.
Never attempt to move the log splitter over hilly or uneven
terrain without a tow vehicle or adequate help.
10.
Always block the wheels to prevent movement of log
splitter while in operation.
Check the fuel before starting the engine. Gasoline is an
11.
extremely flammable fuel. Do not fill the gasoline tank
indoors, when the engine is running, or while the engine
is still hot. Replace gasoline cap securely and wipe off
any splilled gasoline before starting the engine as it may
cause a fire or explosion.
12.
Both ends of each log must be cut as square as
possible to help prevent the log from riding out of the
splitter during operation.
OPERATION
A
1. Stand behind the reservoir tank when operating. See
illustration.
A
PREPARATION
1. Never wear loose clothing or jewelry that can be caught by
moving parts of your log splitter and pull you into it. Keep
clothing away from all moving parts of your log splitter.
2. Wear proper head gear to keep hair away from moving
parts. Always wear protective hearing devices as needed.
3. Always wear safety shoes. A dropped log can seriously
injure your foot.
4. Always wear safety glasses or goggles while operating
your splitter. A piece of splitting log could fly off and hit
your eyes.
If you wear gloves, be sure they are tight fitting without
loose cuffs or draw strings.
6. Use your log splitter in daylight, or under good artificial
light.
2. Know how to stop the unit and disengage the cor trols.
3. Never place hands or feet between log and splitting v /edge
or between log and end plate during forward or reverse
stroke. To do so may result in crushed or ampi fated
fingers or toes, or worse, you may lose an arm or foot.
4. Do not straddle the splitter when using it. A slip in any
position could result in a serious injury.
5. Do not step over your log splitter when the eng ne is
running. You may trip or accidentally activate the
splitting wedge if you step over. If you need to (¡et to
the other side, walk around.
6. Never try to split two logs on top of each other. Dm! may
fly out and injure you.
7. When loading the log splitter, place your hands on th s side
of the log, not at the ends. Never attempt to loac your
splitter while the splitting wedge is in motion. Yon may
get caught by the wedge and injured.
8. Only use your hand to operate the splitting weege or
control lever. Never use your foot or a rope or any other
extension device. This could result in your ability to stop
your splitter quickly enough and cause injury.
9. Always keep fingers away from any cracks that open in
the log during splitting operation. They can quickly close
and pinch or amputate your fingers.
10. Never attempt to split wood across the grain. Some types
of wood may burst or fly out of your splitter and result
in injury to you or a bystander.
11. For logs that are not cut square, the longest portion of the
log should be rotated down and the most square end
placed against the splitting wedge.
12. Keep your work area clean. Immediately removí split
wood around your splitter so that you do not stumble
over it. Clean chips
after each log is split, or whenever necessary to main
tain flat contact between wood and end plate (platlorm).
13. Never move the log splitter while the engine is running.
14. Never leave your log splitter unattended with the e ngine
running. Shut off the engine if you are ieaving your s plittei;
even for a short period of time. Someone could ac ;identally activate the splitting wedge and be injured.
15. Do not run engine in an enclosed area. Exhaust gases
contain carbon monoxide. This odorless gas cm be
deadly when inhaled.
16. Be careful not to touch the muffler after the engir e has
been running as it is HOT.
17. If the equipment should start to vibrate abnormally, stop
the engine and check immediately for the cause. Vi! ¡ration
is generally a warning of trouble.
18. When cleaning, repairing or inspecting, make certain all
moving parts have stopped. Disconnect the spark plug
wire and keep the wire away from the plug to prevent
accidental starting.

MAINTENANCE AND STORAGE
▲
1. Do not operate your splitter in poor mechanical
condition or when in need of repair.
2. Periodically check that all nuts, bolts, screws, hose c lamps
and hydraulic fittings are tight to be sure equiprr ent is
in safe working condition. Where appropriate, chuck all
safety guards and shields to be sure they are ;n the
proper position. Never operate your splitter with safety
guards, shields or other protective features removed.
These safety devices are for your protection.
3. Replace all damaged or worn parts such as hydraulic
hoses and fittings immediately with manufacturer approv
ed replacement parts.
4. Do not change the engine governor settings or overspeed
the engine. This increases the hazard of personal injury.
The maximum engine speed is preset by the manufac-"
turer and is within safety limits.
5. Do not alter your splitter in any manner such as attaching
a rope or extension to the control lever or adding to the
width or height of the wedge. Such alterations may cause
your splitter to be unsafe.
6. Perform all recommended maintenance procedures before
you use your splitter.
7. Do not service or repair your log splitter without
disconnecting the spark plug wire.
8. Never store the equipment with gasoline in the tank
inside of a building where ignition sources are present,
such as hot water and space heaters, clothes dryers and
the like. Allow the engine to cool before storing in any
enclosure.
9. Always store gasoline in an approved, tightly sealed
container. Store the container in a cool, dry place. Do
not store in a building where ignition sources are present.
10. To reduce fire hazard, keep engine free of grass, leaves,
wood chips, and excessive grease and oil.
11. The hydraulic system of your log splitter requires careful
inspection, along with the mechanical parts. Be sure to
replace frayed, kinked, or otherwise damaged hydraulic
components.
12. Fluid escaping from a very small hole can be almost
invisible. Do not check for leaks with your hand.
Escaping fluid under pressure can have sufficient force
to penetrate skin, causing serious personal injury. Leaks
can be located by passing a piece of cardboard or wo'’'"
over the suspected leak and looking for discoloratic
13. Should it become necessary to loosen or remove any
hydraulic fitting or line, be sure to relieve all pressure
by shutting off the engine and moving the control
handle back and forth several times.
14. Do not remove the cap from the hydraulic tank or
reservoir while your log splitter is running. Hot oil under
pressure could cause injury.
15. The pressure relief valve on your splitter is preset at the
factory. Do not adjust the valve. Only a qualified service
technician should perform this adjustment.
16. Completely drain fuel tank prior to storage. This guards
against accumulation of fuel fumes which could result
in a fire hazard.
17. Never store log splitter outside without a waterproof cover.
Rain will cause rust on the inside of the cylinder
TOWING
A
1. This unit should not be towed on any street, highway or
public road without checking the existing federal, local
or state vehicle requirements. Any licensing or modifica
tions such as taillights, etc., needed to comply with the
existing federal, local or state vehicle requirements is the
sole responsibility of the purchaser.
2. Before towing, be certain the log splitter is correctly and
securely attached to the towing vehicle, and the safr ' "
chains are in place. Leave slack in chains for turnr
