IMPORTANT
It is suggested that this manual be read in its entirety before attemtping to assemble or operate. Keep this manual
a safe place for future reference and for ordering replacement parts.
nis unit is shipped WITHOUT GASOLINE or 01L. After assembly, see separate engine manual for proper fuel and
engine oil recommendations.
Your log splitter is a precision piece of power equipment, not a plaything. Therefore exercise extreme caution at all
times.
▲
TRAINING
1. Know the controls and how to stop quicklyREAD THIS OWNER'S MANUAL.
2. Do not allow children to operate. 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.
3. No one should operate this unit while intoxicated
or while taking medication that impairs the senses
or reactions.
4. Never use your splitter for any other purpose
than splitting wood. It is designed for this use
only and any other use may cause an injury.
5. Only the operator is to be near your log splitter
during use. Keep all others, including pets, a
minimum of 20 feet away from your work zone.
Flying wood can be hazardous.
6. Don't step over your splitter when engine is
running. You may trip or accidentally activate
ram if you step over. If you need to get to the
other side, walk around.
PREPARATION
1. Do not wear loose fitting clothing that could get
caught on the moving parts.
2. Do not operate equipment when barefoot or
wearing open sandals. Always wear safety shoes or
heavy boots. A dropped log can seriously injure
your foot.
3. Check the fuel before starting the engine. Do not
fill the gasoline tank indoors, when the engine is
running, or while the engine is still hot. Wipe off
any spilled gasoline before starting the engine.
4. Use only in daylight or in good artificial light.
5. 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.
6. Always wear safety glasses or goggles while operating your log splitter. A piece of splitting log
could fly off and hit your eyes.
7. Both ends of each log must be cut square. This
will prevent the log from flying out of the splitter
while under pressure.
SAFE OPERATION PRACTICES FOR LOG SPLITTERS
OPERATION
1. Do not change the engine governor settings or
overspeed the engine. Excessive engine speeds are
dangerous.
2. Never place hands or feet between log and split
ting wedge or between log and ram during forward
or reverse stroke. To do so may result in crushed
or amputated fingers or toes, or worse, you may
lose an arm or foot.
3. If the equipment should start to vibrate abnor
mally, stop the engine and check immediately for
the cause. Vibration is generally a warning of
trouble.
4. 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.
5. Handle gasoline with care. It is highly flammable.
A. Use approved gasoline container.
B. Never remove cap or add gasoline to a running
or hot engine or fill fuel tank indoors. Wipe
up spilled gasoline.
C. Don't run engine in an enclosed area. Ex
haust gases contain carbon monoxide. This
odorless gas can be deadly when inhaled.
6. Stand behind the ram when operating. See draw
ings.
7.
Be careful not to touch the muffler after the
engine has been running. It is HOT.
8
Never try to split two logs on top of each other.
One may fly out and injure you.
When loading the log splitter, place your hands on
9.
the sides of the log, not at the ends.
10. 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 ram.
Page 4
11. Never attempt to split wood across the jrain.
Some types of wood may burst or fly ojt of
your splitter and result in injury to you or a
bystander.
12. Never leave your log splitter unattended wilh the
engine running. Shut off the engine if yoj are
leaving your splitter, even for a short period of
time. Someone could accidentally activât; the
ram and be injured.
13. Only use your hand to operate the ram or cc ntrol
lever. Never use your foot or a rope or any ather
extension device. This could result in your i labil
ity to stop your splitter quickly enough and
cause an injury.
14. Only operate your splitter on the level ground and
not on the side of a hill. It could tip, or railing
logs or poor footing could cause an acc dent.
This also prevents the spillage of gas from the
tank.
MAINTENANCE and STORAGE
1. Don't operate your splitter in poor mechmical
condition or when in need of repair.
2. Keep ail nuts, bolts, screws, hose clamp ; and
hydraulic fittings tight to be sure equipm;nt is
in safe working condition.
3. Replace all damaged or worn parts such cs hy
draulic hoses and fittings immediately with manu
facturer approved replacement parts.
4. Never store the equipment with gasoline in the
tank inside of a building where fumes may reach
an open flame or spark. Allow the engine to cool
before storing in any enclosure. _
5. To reduce fire hazard keep engine free of grai
leaves, wood chips, excessive grease and oil.
6. The hydraulic system of your log splitter re
quires the careful inspection along with the
mechanical parts. Be sure to replace frayed,
kinked, cracked or otherwise damaged hydraulic
components.
7. Fluid escaping from a very small hole can almost
be 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 wood over the suspected
leak and looking for discoloration.
8. 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.
9. Don't remove the cap from the hydraulic tank or
reservoir while your log splitter is running. Hot
oil under pressure could cause injury.
10. Never store outside without a waterproof cover—
Rain will cause rust on the inside of the cylinder
