Split wood with the grain (iengthwise) only
NEVER:
Use fluid below 0° F,, or above 150° F.
Use a solid engine/pump coupling
Force pump when mounting
Operate through relief valve for more than several
seconds
Attempt to adjust unloading or relief valve settings
without pressure gauges
Operate with air in hydraulic system
Use Teflon tape on hydraulic fittings
Warm up engine apart from pump in cold weather
Attempt to cut wood across the grain
CONDITIONS WHICH WILL VOID YOUR WARRANTY
1. Failure to maintain proper fluid level in reservoir will void your warranty, causing permanent damage to pump
by allowing air to be drawn into pump. Fluid will become foamy. Refer to “Initial Preparation” in the Operation
section of this manual.
2. Changing the relief valve setting or pressure adjustment of control valve without proper knowledge and
instruction from the factory wili void your warranty. A very minor adjustment could destroy the structural and
safety limits for which the unit was designed. The system will produce more power than the structure will with
stand. Higher pressure could cause the hoses to burst, cylinder to rupture and intense fluid releases, which
could result in serious personal injury.
3. Disassembling the pump wiil void your warranty. If replacement is necessary, merely disconnect and replace.
Do not attempt to adjust pump settings, as they are adjusted by the manufacturer at the factory.
4. Use of incorrect hydraulic fluid will void your warranty. Use only Dexron II automatic transmission fluid or 10W
non-foaming hydraulic fluid.
5. The flexible pump coupler must be inspected regularly. Allowing the coupler to deteriorate will void your war
ranty. Deterioration of spider insert and prolonged use after deterioration will destroy pump bearings and
engine bearings, along with total destruction of coupler hubs.
6. Improper beam lubrication will cause premature wear and looseness. Lubricate the beam regularly. Lack of
lubrication will void your warranty.
7. Improper adjustment of splitting wedge will void your warranty. Become familiar with the proper tolerance
required for adjustment of the splitting wedge as instructed in the Adjustment section of this manual.
a. If wedge is too loose, cylinder beam and wedge wear will result. Allowing the wedge to loosen and be
used under operating stress will cause damage which will not be covered under warranty.
b. If wedge is too tight, severe beam damage will result which will not be covered under warranty.
8. Warranty card must be mailed or delivered directly to factory. Proper information must be completed and
mailed as per instructions. No warranty records on file may result in delay.
9. Do not overheat the hydraulic system. Excessive heat will destroy the hydraulic system with hardened Orings and excessive friction.
10. Do not attempt to start in temperatures under 20° F. without pre-heating fluid in reservoir. Excessively cold
fluid cannot circulate and draw into pump. Warranty will be void.
11. Repair any leaks in hydraulic system immediately. Unattended leaks will cause air to enter system and/or
decrease fluid level in reservoir, causing damage to the hydraulic system which will not be covered by war
ranty.

RULES FOR SAFE OPERATION
THIS SYMBOL POINTS OUT IMPORTANT SAFETY INSTRUCTIONS WHICH, IF NOT FOLLOWED, COULD ENDANGER THE PERSON
AL SAFETY AND/OR PROPERTY OF YOURSELF AND OTHERS. READ AND FOLLOW ALL INSTRUCTIONS IN THIS MANUAL BEFORE
AHEMPTING TO OPERATE YOUR LOG SPLIHER. FAILURE TO COMPLY WITH THESE INSTRUCTIONS MAY RESULT IN PERSON
AL INJURY. WHEN YOU SEE THIS SYMBOL— A HEED ITS WARNING.
A
A
A
Your log splitter was built to be operated according to the ruies 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.
TRAINING
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 equip
ment, not a toy. 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.
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 con
trol 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 whiie tak
ing 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.
DANGER
A
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 pre
vents the spillage of gasoline from the fuel tank.
9. Never attempt to move the log splitter over hilly or uneven ter
rain 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 spilled 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 oper
ation.
OPERATION
1. Stand behind the reservoir tank when operating. See illustra
tions.
A
PREPARATfON
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.
5. 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.
7. Never operate your splitter on slippery, wet, muddy or icy sur
faces. Safe footing is essential in preventing accidents. Never
operate your splitter while attached to a towing vehicle.
2. Know how to stop the unit and disengage the controls.
3. Never place hands or feet between log and splitting wedge or
between log and end plate 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.
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 engine is running.
You may trip or accidentally activate the splitting wedge if you
step over. If you need to get to the other side, walk around.
6. Never try to split two logs on top of each other. One may fly
out and injure you.
7. When loading the log splitter, place your hands on the side of
the log, not at the ends. Never attempt to load your splitter
while the splitting wedge is in motion. You may get caught by
the wedge and injured.
8. Only use your hand to operate the splitting wedge or control
lever. Never use your foot or a rope or any other extension
device. This could result in your inability to stop your splitter
quickly enough to avoid 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 woods 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 remove split wood
around your splitter so that you do not stumble over it. Clean
chips and dirt off end plate (wood platform) after each log is
split, or whenever necessary to maintain flat contact between
wood and end plate (platform).
13. Never move the log splitter while the engine is running.
14. Never leave your log splitter unattended with the engine run
ning. Shut off the engine if you are leaving your splitter, even
for a short period of time. Someone could accidentally activate
the splitting wedge and be injured.
15. Do not run engine in an enclosed area. Exhaust gases contain
carbon monoxide. This odorless gas can be deadly when
inhaled.
16. Be careful not to touch the muffler after the engine has been
running. It will be HOT!
17. If the equipment should start to vibrate abnormally, stop the
engine and check immediately for the cause. Vibration is gen
erally a warning of trouble.
18. When cleaning, repairing or inspecting, make certain all mov
ing parts have stopped. Disconnect the spark plug wire and
keep the wire away from the plug to prevent accidental start
ing.
3. Replace all damaged or worn parts such as hydraulic hoses
and fittings immediately with manufacturer approved replace
ment parts.
4. Do not change the engine governor settings or overspeed the
engine. This increases the hazard of personal injury. The maxi
mum engine speed is preset by the manufacturer 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 and moving it away from the spark plug.
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 build
ing 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 iocated by passing a
piece of cardboard or wood over the suspected leak and look
ing for discoloration.
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 facto
ry. 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.
A
CUSTOMER RESPONSIBILITIES
