Excessive high speeds may cause the log splitter
to "fishtail" or otherwise become unstable.
Check the tire pressure on the log splitter tires. It
must be 30 p.s.i, maximum for highway travel.
When parking, storing or using your log splitter,
keep the coupler off the ground so dirt will not
build up in the ball socket.
• Do not allow anyone to sit or ride on your log
splitter. They can easily fall off and be seriously
injured.
Training
• Before operating this log splitter, read and
understand this operator's 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 log splitter who has not
read this manual. Keep this manual in a safe
place for future and regular reference and for
orderingreplacement parts.
Never use your splitter for any other purpose than
splitting wood. Itis designed for this use and any
other use may cause an injury. Your log splitter is
a precision piece of power equipment, not a toy.
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.
••Only the operator isto be near your log spSitter
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
3

helperisassistinginloadinglogs,neveractivate
thecontroluntilthehelperisclear of the area.
More accidents occur when more than one
person operates the log splitter than at any other
time.
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 log splitter.
Preparation
• 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.
• Wear proper head gear to keep hair away from
moving parts. Always wear protective hearing
devices as needed.
• Always wear safety shoes. A dropped log can
seriously injure your foot.
•Always wear safety glasses or goggles while
operating your splitter. A piece of splitting log
could fly off and hit your eyes.
Wear leather work gloves. Be sure they are tight
fitting without loose cuffs or draw strings.
• Use your logsplitter in daylight, or under good
artificial light.
•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. Itcould 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.
• Never attempt to move the log splitter over hilly
or uneven terrain without a tow vehicle or
adequate help.
Always block the wheels to prevent movement
of log splitter while in operation.
• 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 isstill hot. Replace
gasoline cap securely and wipe off any spilled
gasoline before starting the engine as it may
cause afire or explosion.
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
Vertical Operating Position: Stand in front of
the log splitter.
Horizontal Operating Position: Stand behind
the reservoir tank. See illustrations,
Know how to stop the unit and disengage the
controls.
Never place hands or feet between log and
splitting wedge or between logand 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.
Do not straddle the splitter when using it. A slip
in any position could result in a serious injury.
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.
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 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.
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.
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.

Customer Responsibilities
• Do not operate your splitter in poor mechanical
condition or when in need of repair.
Periodically check that all nuts, bolts, screws,
hose clamps and hydraulic fittings are tight to be
sure equipment is in safe 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 protective features removed.
These safety devices are for your protection.
Replace all damaged or worn parts such as
hydraulic hoses and fittings immediately with
manufacturer approved replacement parts.
Do net change the engine governor settings or
overspeed the engine. This increases the
hazard of personal injury. The maximum engine
speed is preset by the manufacturer and is
within safety limits.
Do not alter your log 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.
Perform all recommended maintenance
procedures before you use your splitter.
Do not service or repair your log splitter without
disconnecting the spark plug wire and moving it
away from the spark plug.
• 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.
•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.
• To reduce fire hazard, keep engine free of grass,
leaves, wood chips, and excessive grease and
oil.
The hydraulic system of your leg splitter requires
careful inspection, along with the mechanical
parts. Be sure to replace frayed, kinked, or
otherwise damaged hydraulic components.
• 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.
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.
• Do not remove the cap from the hydraulic tank or
reservoir while your log splitter is running. Hot oil
under pressure could cause injury.
• 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.
• Completely drain fuel tank prior to storage. This
guards against accumulation of fuel fumes
which could result in a fire hazard.
• Never store log splitter outside without a
waterproof cover. Rain will cause rust on the
inside of the cylinder.
Important Information
Always:
Use clean fluid and check fluid level regularly.
Use Dexron Ill Automatic Transmission Fluid or
lOW non-foaming hydraulic fluid.
Use a filter (clean or replace regularly).
Use a breather cap on fluid reservoir.
5

• Make certain pump is mounted and aligned
properly.
•Use a flexible "spider" type coupling between
engine and pump drive shafts.
Keep hoses clear and unblocked.
Bleed air out of hoses before operating.
Flush and clean hydraulic system before start-
up after any malfunction or servicing.
• Use "pipe dope" on all hydraulic fittings.
Allow time for warm-up before splitting wood.
• Prime the pump before initial start-up by turning
over the engine with spark plug disconnected.
• Split wood with the grain (lengthwise) only.
Never:
Use when fluid is below 20° F, or above 150° F.
Use a solid engine/pump coupling.
Force pump when mounting.
Operate through relief valve.
Attempt to adjust unloading or relief valve
settings without pressure gauges.
Operate with air in hydraulic system.
Use Teflon tape on hydraulic fittings.
Attempt to cut wood across the grain.

Check the hose clamps on the return hose at
least once a season.
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 check the bolts on the side of the
wedge plate to eliminate excess space between
the wedge plate and the beam.
The wedge plate on the log splitter is designed
so the gib blocks on the side of the wedge plate
can be easily removed and rotated or turned
over for even wear. You can locate these two gib
blocks behind the gib plate shown in the figure
below. Make certain to readjust the adjustment
bolts so wedge moves freely, but no excess
space exists between the wedge plate and
beam. See Figure 12.

Tires
•See sidewall oftire for recommended pressure.
Maximum tire pressure under any
circumstances is 30 p.s.i. Equal tire pressure
should be maintained on all tires.
WARNING; Excessive pressure (over 30
p.s.i.) when seating beads may cause tire/
rim assembly to burst with force sufficient to
cause serious injury.
Flexible Pump Coupler
The flexible pump coupler is a nylon "spider" insert,
located between the pump and engine shaft, Over a
period of time, the coupler will harden and
deteriorate. Replace the coupler ifyou detect
vibration or noise in the area between the engine and
the pump. If the coupler fails completely, you will
experience a loss of power.
,_ WARNING: Never hit the engine shaft in
any manner, as a blow will cause permanent
damage to the engine.
IMPORTANT: Ifyou do not have the right tools or are
otherwise uncomfortable with the procedure, contact
Sears service center.
When replacing the flexible pump coupler, proceed
as follows. Follow the instructions carefully as the
alignmentis critical.
•Disconnect the spark plug wire, and secure it
away from the spark plug.
•Drain gasoline from fuel tank or place a piece of
plastic film underneath the gas cap to prevent
gasoline from _eaking.
• Using a 1/2 inch socket with an extension,
remove the three bolts securing the engine to
the engine mounting bracket. The three bolts
can be found under the engine mounting
bracket.
Carefully lift engine off mounting bracket and set
aside on a sturdy, level surface.
• Remove the nylon spider insert from the pump
shaft. You may need a pair of needle nose
pliers to grasp the insert.
Place a new "spider" insert intothe pump coupling
half. See Figure 16,1. Make sure the key ison the
pump shaft. The key way in the lower coupling
half has to fit over the key on the pump shaft.
Re-seat the engine making sure to align the
pump and engine coupling halves. There must 16
be space between end oftheengine and the
coupling haft. See Figure 16,2.

Reattach spark plug wire to spark plug. Be sure
to remove plastic film from under gas cap if
necessary.
Beam & Splitting Wedge
The wedge plate is subject to normal wear.
Periodically adjust the bolts on the wedge plate
making sure that the wedge moves freely. Also make
sure that no excess space exists between the wedge
plate and the beam,

To adjust:
•Loosen three hex bolts on top ofthe wedge plate
(beneath the splittingwedge). See Figure 17.
• Loosen the lock nuts on the two adjustment
bolts on the side of the gib plate, located
beneath the splitting wedge. See Figure 17.
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 adjustment bolts in this position.
Retighten the three hex bolts on top of the
wedge plate.

Adjusting Carburetor
AWARNING: Ifyou make any adjustments to
the engine while it isrunning, keep clear of all
moving parts to avoidinjury. Be careful of
heated surfaces and muffler.
If the engine carburetor needs adjustment, contact
your nearest Sears service center.
Engine performance may be affected in altitudes
above 4,000 feet. To improve engine performance,
install a high altitude adjustment kit. This kit is
available at Sears service centers.
Engine Speed
The engine speed on your log splitter has been set by
the engine manufacturer. 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,
contact Sears service center for repair and
adjustment.
,_ IMPORTANT: Changing of engine governed
speed by the customer will void engine
warranty.

Prepare your log splitter for storage at the end of the
season or if the log splitter will not be used for 30 days
or more.
WARNING: Never store machine with fuel
in the fuel tank inside of building where
fumes may reach an open flame or spark, or
where ignition sources are present such as
hot water and space heaters, furnaces,
clothes dryers, stoves, electric motors, etc.
NOTE: A yearly check-up by your local Sears Service
Center is a good way to make certain your log spfitter
willprovide maximum performance for the next
season.
LOG SPLITTER
Clean the log splitter thoroughly.
Wipe unit with an oiled rag to prevent rust,
especially wedge and beam.
ENGINE
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
separation and formation of acids during storage.
Acidic gas can damage the fuel system 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.
• Drain carburetor by pressing upward on bowl
drain which is located below the carburetor.
•Never use engine or carburetor 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 storage
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 carburetor if using
fuel stabilizer. Drain all the oil from the
crankcase (this should be clone after the engine
has been operated and is still warm) and refill
the crankcase with fresh oil.
Ifyou have drained the fuel tank, protect the
inside of the engine as follows.
• Remove spark plug, pour approximately 1/2
ounce (approximately one tablespoon) 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 itstarts to rust.
Rust and/or dirt in the gasoline will cause
problems. Store unit in a clean, dry area. Do not
store next to corrosive materials, such as
fertilizer.
NOTE: If storing in an unventilated or metal storage
shed, be certain to rustproof the equipment by coating
with a light oil or silicone.
