IMPORTANT
SAFETY RULES
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
ATTEMPTING TO OPERATE YOUR LOG SPLITTER. FAILURE TO COMPLY WITH THESE INSTRUCTIONS MAY RESULT IN PERSON
AL INJURY. WHEN YOU SEE THIS SYMBOL— ^ HEED ITS WARNING.
A
Your log splitter was built to be operated according to the rules tor 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
A
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 haz
ardous. 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 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.
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.
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.
A
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 tire 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 illus
trations.
Page 3
2. Know how to stop the unit and disengage the controls.
3. Never place hands or teet 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 it 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 located 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 wilt cause rust on the inside of the cylinder.
A
CUSTOMER RESPONSIBILITIES
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 clamps and

working condition. Where appropriate, check all safety guards
and shields to be sure they are in the proper position. Never
operate your splitter with safety guards, shields or other pro
tective features removed. These safety devices are for your
protection.
A
TOWING
1. This unit should not be towed on any street, highway or public
road without checking the existing federal, local or state vehi
cle requirements. Any licensing or modifications such as taillights, etc., needed to comply with the existing federal, local or
state vehicle requirements is the sole responsibility of the pur
chaser.
2. Before towing, be certain the log splitter is correctly and
securely attached to the towing vehicle, and the safety chains

over, approximately 10 times. Reconnect the
spark plug wire.
• Start engine. Use the control handle to extend the
wedge to the far extended position. Leave the
wedge in this position (do not retract).
• Refill tank to within 1-1/2" to 2" from the top of the
tank.
• Now retract the wedge. Extend and retract the
wedge fully 10 to 12 complete cycles to remove
trapped air in the system (system is “self-bleed
ing").
• Refill the reservoir to within 1-1/2" to 2" from the
top of the tank. Much of the original fluid has been
drawn into the cylinder and hoses. Make certain to
refill the reservoir, to prevent extreme damage
to the hydraulic pump. Failure to refill the tank
will void your warranty.
NOTE: Some fluid may overflow from the vent plug as
the system builds heat and the fluid expands and
seeks its own level.
WARNING: DO NOT OPERATE THE LOG
SPLITTER WITHOUT THE PROPER
A
AMOUNT OF TRANSMISSION FLUID IN
THE RESERVOIR TANK.
TO START ENGINE
• Open cover (on top of fuel tank) and attach spark
plug wire and rubber boot to spark plug if neces
sary. See figure 11.
• Open fuel shut-off valve by turning in direction of
arrow. See figure 13.

NOTE: If the throttle control lever fails to stay in the
desired position or if it is hard to move, refer to the
service and adjustment section.
• Move choke lever down to CHOKE position.
• Place the engine shut-off switch in ON position.
See figure 13.
• Grasp starter handle (see figure 11) and pull rope
out slowly until engine reaches start of compres
sion cycle (rope will puli slightly harder at this
point). Let the rope rewind slowly.
• Pull rope with a rapid, continuous, full arm stroke.
Keep a firm grip on starter handle. Let rope rewind
slowly. Do not let starter handle snap back against
starter.
• Repeat preceding two instructions until engine
fires. When engine starts, move choke lever on
engine halfway between CHOKE and RUN.
NOTE: If engine does not fire after three attempts,
move choke lever halfway between CHOKE and RUN
position and try again. See figure 13.
• Run wedge up and down beam 6 to 8 times to cir
culate the hydraulic fluid, which will warm and thin
the fluid.

TENANCE OR ADJUSTMENTS.
LOG SPLIHER
RESERVOIR FLUID
Check the hydraulic fluid level in the log splitter reser
voir tank before each use. Fluid level should be 1-1/2“
to 2" from the top of the tank.
Change the hydraulic fluid in the reservoir every 100
hours of operation. Disconnect the suction hose from
the bottom of the reservoir tank, and drain the fiuid
into a suitable container. Refill using only Dexron II
automatic transmission fluid, as instructed in the
BEFORE INITIAL USE section of this manual. Also,
make certain to change the hydraulic filter.
NOTE: Drain the fluid and flush the reservoir tank and
hoses with kerosene whenever any repair work is per
formed on the tank, hydraulic pump or valve.
Contaminants in the fluid wilt damage the hydraulic
components (should be performed by your SEARS
Service Center).
WARNING: USE EXTREME CAUTION
WHEN WORKING WITH KEROSENE, AS

BEAM AND SPLITTING WEDGE
Lubricate both sides of the beam where it contacts the
splitting wedge with engine oil before each use to
obtain years of service. However, normal wear will
occur. Periodically adjust the bolts on the side of the
wedge plate as follows to eliminate the excess space
between the wedge plate and the beam. See figure
14.
• Loosen the three hex bolts on top of the wedge
plate (beneath the splitting wedge).
• Loosen the lock nuts on the two adjustment bolts
on the side of the gib plate, located beneath the
splitting wedge. Turn the adjustment bolts in until
snug, then back them off slowly until the wedge
assembly will slide on the beam.
• Tighten the lock nuts securely against the gib plate
to hold the adjustment bolts in this position.
• Retighten the three hex bolts on top of the wedge
plate.

ENGINE OIL
Only use high quality detergent oil rated with API ser
vice classification SG. Select the oil’s viscosity grade
according to your expected operating temperature.
Colder
5W30
NOTE: Although multi-viscosity oil (5E30, 10W30,
etc.) improves starting in cold weather, these multi
viscosity oils will result in increased oil consumption
when used above 32° F. Check your oil level more
frequently to avoid possible engine damage from run
ning low on oil.

Page 14
Your four-cycle engine will normally consume some
oil; therefore, check engine oil level regularly—
approximately every five hours of operation and
before each usage. Stop engine and wait several
minutes before checking oil level. With engine level,
the oil must be to the FULL mark on dipstick (refer to
figure 11). Change engine oil after the first five hours
of operation, and every twenty-five hours thereafter.
To Drain Oil:
• Drain oil while engine is warm.
a. Remove oil drain plug. Catch oil in a suitable
container.
b. When engine is drained of all oil, replace drain
plug securely.
• Refill with fresh oil. Refer to GAS AND OIL FILL
UP section.
• Replace dipstick.
AIR CLEANER
The air cleaner prevents damaging dirt, dust, etc.,
from entering the carburetor and being forced into the
engine and is important to engine life and per
formance.
Never run your engine without air cleaner com
pletely assembled.
To Service Air Cleaner:
Service pre-cleaner after every 25 hours of use, or at
least once a season. Service cartridge every 100 hours
of use, or at least once a season. Service pre-cleaner
and cartridge more often under dusty conditions.
• Loosen air cleaner cover screws. Remove cover
and air cleaner assembly from base. See figure 15.
• Remove air cleaner assembly from inside cover
and disassemble.
• To service foam pre-cleaner: Remove pre-cleaner.
Wash in liquid detergent and water. Squeeze dry in
a clean cloth. Saturate in engine oil. Squeeze in a
clean, absorbent cloth to remove all excess oil. If
pre-cleaner is very dirty, replace it.
• To service cartridge; Clean by tapping gently on a
flat surface. If very dirty, replace. Do not oil cartridge,
NOTE: Do not use petroleum solvents (e.g. kerosene)
or pressurized air to clean cartridge. They will cause
cartridge to deteriorate.
• Reassemble retainer on pre-cleaner and cartridge
(screen side of pre-cleaner toward cartridge
pleats). Place assembly into cover.
• Insert tabs on cover into slots in base and tighten
cover screws securely.
CLEAN ENGINE
Clean engine periodically. Remove dirt and debris
with a cloth or brush. Cleaning with a forceful spray of
water is not recommended as water could contami
nate the fuel system.
Yearly or every 25 hours, whichever occurs first,
remove the blower housing and clean the areas
shown in figure 16 to avoid overspeeding, overheating
and engine damage. Clean more often if necessary.
WARNING: PERIODICALLY CLEAN MUF

IMPORTANT: IT IS IMPORTANT TO PREVENT
GUM DEPOSITS FROM FORMING IN ESSENTIAL
FUEL SYSTEM PARTS SUCH AS CARBURETOR.
FUEL FILTER, FUEL HOSE, OR TANK DURING
STORAGE. ALSO, EXPERIENCE INDICATES THAT
ALCOHOL BLENDED FUELS (CALLED GASOHOL
OR USING ETHANOL OR METHANOL) CAN
ATTRACT MOISTURE WHICH LEADS TO SEPARA
TION AND FORMATION OF ACIDS DURING STOR
AGE. ACIDIC GAS CAN DAMAGE THE FUEL SYS
TEM OF AN ENGINE WHILE IN STORAGE.
• Drain the fuel tank.
• Start the engine and let it run until the fuel lines and
carburetor are empty.
• Never use engine or cart>uretor cleaner products in
the fuel tank or permanent damage may occur.
• Use fresh fuel next season.
NOTE: Fuel stabilizer is an acceptable alternative in
minimizing the formation of fuel gum deposits during
storage. Add stabilizer to gasoline in fuel tank or stor
age container. Always follow the mix ratio found on
stabilizer container. Run engine at least 10 minutes
after adding stabilizer to allow the stabilizer to reach
the carburetor. Do not drain the gas tank and carbure
tor if using fuel stabilizer.
• Drain all the oil from the crankcase (this should be
done after the engine has been operated and is still
warm) and refill the crankcase with fresh oil.
• If you have drained the fuel tank, protect the inside
of the engine as follows. Remove spark plug, pour
approximately 1/2 ounce (approximately one table
spoon) of engine oil into cylinder and crank slowly
to distribute oil. Replace spark plug.
OTHER
• Do not store gasoline from one season to another.
• Replace your gasoline can if your can starts to rust.
Rust and/or dirt in your gasoline will cause problems.
• Store unit in a clean, dry area.

NOTE: A dirty air cleaner will cause engine to run
rough. Be certain air cleaner is clean and attached to
the carburetor before adjusting carburetor. Do not
make unnecessary adjustments. Factory settings are
satisfactory for most applications and conditions.
Never attempt to change maximum engine speed. It is
pre-set at the factory and should be changed only by
a qualified service technician who has the necessary
equipment.
The carburetor may need re-adjusting if engine lacks
power or does not idle properly. If adjustments are
needed, proceed as follows,
• Close idle mixture valve (see figure 21) clockwise
() finger tight only. Forcing may cause damage.
Then open 1 -1/2 turns counterclockwise ().
• Start engine and allow to warm for five minutes.
• Move throttle control lever to IDLE position.
• Rotate throttle counterclockwise (^ ) and hold
against idle speed adjusting screw. Turn idle speed
adjusting screw until engine is running at 1750
RPM.
• Turn idle mixture valve clockwise ) (lean mix
ture) until engine JUST starts to slow. Then turn it
counterclockwise (^) (rich mixture) until engine
starts to run unevenly. Set at midpoint between rich
and lean mixture.
• Recheck idle RPM and readjust if necessary.
• Move throttle control lever to FAST position.
Engine should accelerate without hesitation or
sputtering. If it does not, carburetor should be read
justed, usually to a slightly richer mixture.
ENGINE SPEED
Your engine speed has been factory set. Do not
attempt to increase engine speed or it may result in
personal injury. If you believe the engine is running
too fast or too slow, take your log splitter to the
nearest SEARS Service Center for repair and adjust
ment.
TIRES
Recommended operating tire pressure is 12 to 15
p.s.i. (sidewall of tire may give tire manufacturer's rec
ommended pressure). Maximum tire pressure under
any circumstances is 30 p.s.i. Equal tire pressure
should be maintained on all tires.
When installing a tire to the rim, be certain rim is
clean and free of rust. Lubricate both the tire and rim
generously. Never Inflate to over 30 p.s.i. to seat
beads.
