WARNING
ÂÜ
This unit is equipped with an internal combustion engine and should not be used on or near any unimproved
forest-covered, brush-covered or grass-covered land unless the engine's exhaust system is equipped with
a spark arrester meeting applicable local or state laws (if any). If a spark arrester is used, it should be
maintained in effective working order by the o aerator.
In the State of California the above is required by law (Section 4442 of the California Public Resources Code).
Other states may have similar laws. Federal lavfs apply on federal lands. A spark arrester for the muffler

A
I WARNING (
To reduce the potential for any injury, comply with the following safety instructions. Failure to
comply with the instructions may result in personal injury.
SAFE OPERATION PRACTICES FOR LOG SPLITTERS
TRAINING
1. Before operating this splitter, read and under
stand 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.
3. 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.
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.
7. Never operate your splitter on slippery, wet,
muddy or icy surfaces. Safe footing is essen
tial in preventing accidents. Never operate your
splitter while attached to a towing vehicle.
8.
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.
11.
Check the fuel before starting the engine.
Gasoline is an 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
1. Stand behind the ram when operating. See
illustrations.
T
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.
o. If you wear gloves, be sure they are tight fitting
without loose cuffs or draw strings.

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 ram.
12. Keep your work area clean. Immediately remo/e
split wood around your splitter so that you do

MAINTENANCE AND STORAGE
1. Do not operate your splitter in poor mechani :al
condition or when in need of repair.
2. Periodically check that all nuts, bolts, screvt/s,
hose clamps and hydraulic fittings are tight to
be sure equipment is in safe working condition.
Where appropriate, check all safety guards e nd
shields, to be sure they are in the proper
position. Never operate your splitter with sefety guards, shields or other protective featu 'es
removed. These safety devices are for your
protection.
3. Replace all damaged or worn parts such as
hydraulic hoses and fittings immediately with
manufacturer approved replacement parts.
4. Do not change the engine governor settingj or
overspeed the engine. This increases the hazard
of personal injury. The maximum engine speied
is preset by the manufacturer and is within s£ fe-
ty 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 split
ter to be unsafe.
6. Perform all recommended maintenance pro
cedures 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 wood over the
suspected leak and looking for discoloration.
13. Should it become necessary to loosen or remove
any hydraulic fitting or line, be sure to relieve a
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 pre
set 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 water
proof cover. Rain will cause rust on the inside
of the cylinder.
TOWING
1. This unit should not be towed on any street,
highway or public road. Any licensing 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 safety chains (if so equipped
or where required by state law) are in place.
Leave slack in chains for turning allowance.
3. Do not allow anyone to sit or ride on you
splitter. They can easily fall off and be serious
ly injured.
