IMPORTANT
RULES FOR SAFE OPERATION
THIS SYMBOL POINTS OUT IMPORTANT SAFETY INSTRUCTIONS WHICH, IF NOT FOLLOWED, COULD ENDANGER THE PERSONAL
SAFETY AND/OR PROPERTY OF YOURSELF AND OTHERS. READ AND FOLLOW ALL INSTRUCTIONS IN THIS MANUAL BEFORE AT
TEMPTING TO OPERATE YOUR LOG SPLIHER. FAILURE TO COMPLY WITH THESE INSTRUCTIONS MAY RESULT IN PERSONAL IN
k
JURY. WHEN YOU SEE THIS SYMBOL-A HEED ITS WARNING.
A
AC
Your log splitter was built to be operated according to tbe rules 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
Before operating this splitter, read and understand this manual com
pletely. 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.
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, excercise 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 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 per
son 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 splitter.
DANGER
Only operate your splitter on level ground and not on the side of
a hill. It could tip, or roiling 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 mo\re 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 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.
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.
A
OPERATION
• Stand behind the reservoir tank when operating. See illustration.
PREPARATION
ik
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 split
ter. A piece of splitting log could fly off and hit your eyes.
If you wear gloves, be sure they are tight fitting without loose cuffs
or draw strings.
Use your log splitter 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.
Page 4
• Know how to stop the unit and disengage the controls.
• Never place hands or feet between log and splitting wedge or be
tween 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.
• 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 ability to stop your splitter quickly enough and
cause injury.
• Always keep fingers away from any cracks that open in the log dur
ing splitting operation. They can quickly close and pinch or amputate
your fingers.
• 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.
• 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 split
ting wedge.
• 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).
• Never move the log splitter while the engine is running.
• Never leave your log splitter unattended with the engine running.
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.
• Do not run engine in an enclosed area. Exhaust gases contain car
bon monoxide. This odorless gas can be deadly when inhaled.
• Be careful not to touch the muffler after the engine has been run
ning as it is HOT.
• If the equipment should start to vibrate abnormally, stop the engine
and check immediately for the cause. Vibration is generally a warn
ing of trouble.
• 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.
A
MAINTENANCE
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 split
ter 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 fit
tings immediately with manufacturer approved replacement parts.
• Do not 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 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.
• 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 log splitter requires careful inspec
tion, 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 fit
ting 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 ac
cumulation 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.
A
TOWING
• This unit should not be towed on any street, highway or public road
without checking the existing federal, local or state vehicle re
quirements. 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 purchaser.
• Before towing, be certain the log splitter is correctly and securely
attached to the towing vehicle, and the safety chains are in place.
Leave slack in chains for turning allowance.
• Do not allow anyone to sit or ride on your splitter. They can easily
fall off and be seriously injured.
NOTE: 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 operator.
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 laws apply on federal lands. A spark arrester for the muffler is available at your Sears Authorized Service Center.

start the engine and let it run until the fuel lines and
INITIAL PREPARATION
• Place log splitter on a firm, level surface. For ver
tical operation, remove the quick release pin from
the latch bracket. Place the beam in the vertical posi
tion. Place the quick release pin through the holes
in the beam mounting plates and the brackets on the
reservoir tank. See figure 14.
FIGURE 14.
• Lubricate the beam area where beam will slide with
engine oil (DO NOT USE GREASE). Make certain
to oil both front and back of the beam face.
Page 10
• Fill the reservoir tank as follows.
a. Remove reservoir vent plug. See figure 14. Using
Dexron II automatic transmission fluid, fill reser
voir to the top. Replace vent plug securely.
b. Disconnect the spark plug wire. Prime the pump
by pulling the recoil starter, to turn the engine
over, approximately 10 times. Reconnect the
spark plug wire.
c. Start engine. Use the control handle to extend the
wedge to the far extended position. Leave the
wedge in this position (do not retract).
d. Refill tank to within 1 ¥2" to 2" from the top of the
tank. Total capacity of system is approximately
7.6 gallons.
e. 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
bleeding”).
f. Refill the reservoir to within 1V
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
2
" to 2" from the
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.
TO START ENGINE
• Place throttle control lever on the engine in FAST
position. See figure 15.
• Place choke lever in CHOKE position.
NOTE: A warm engine may not require choking.
• Grasp starter handle and pull rope out slowly until
engine reaches start of compression cycle (rope will
pull slightly harder at this point). Let the rope rewind
slowly.
• Pull rope with a rapid, continuous, full arm stroke.
Keep a firm grip on the starter handle. Let the rope
rewind slowly. Do not let starter handle snap back
against starter.
• Repeat preceding instructions 3 and 4 until engine
fires. When engine starts, move choke lever halfway
between CHOKE and RUN.
• Move throttle control lever to IDLE position for a few
minutes warm-up. Gradually move choke lever to
RUN position as engine warms up.
NOTE: In order to idle smoothly, a new engine may re
quire 3 to 5 minutes running above slow idle speed.
Idle speed has been adjusted to be correct after this
break-in period.
• If weather is cold, run wedge up and down beam 6
to 8 times to circulate the hydraulic fluid, which will
warm and thin the fluid.
WARNING: DO NOT OPERATE THE LOG
SPLITTER WITHOUT THE PROPER

• Move the control handle to reverse position to return
the splitting wedge.
WARNING: IIF THE FLUID BECOMES EX
CESSIVELY HOT AT ANY TIME DURING
A
OPERATION, STOP THE UNIT AND
ALLOW THE FLUID TO COOL DOWN.
MAXIMUM PERFORMANCE WILL NOT BE
OBTAINED FROM OUR LOG SPLITTER IF
THE FLUID IS TOO HOT. USE EXTREME
CAUTION AS CONTACTING HOT FLUID
COULD RESULT IN SERIOUS PERSONAL
INJURY.
TO OPERATE LOG SPLITTER:
• Set throttle at maximum speed (3450-3600 RPM).
• Place the log upright, on top of end plate for vertical
operation, and on top of beam for horizontal
operation.
• Push the control handle to forward position until the
splitting wedge just contacts the log. Release the
control handle.
• Step behind the reservoir tank (see figures 16 or
17) and push the control handle in forward position
until the log is split.
TO TRANSPORT LOG SPLIHER
• Lower the beam to its horizontal position. Make cer
tain the latch bracket is latched securely around the
tongue and secured with the quick release pin.
• Remove the quick release pin which secures the jack
stand. Pivot it up against the tongue, and secure with
the quick release pin.
• Attach the hitch to a towing vehicle, making certain
to latch securely. Attach the safety chains to the tow
ing vehicle.
ADJUSTMENT
SPLITTING WEDGE
As normal wear occurs, periodically adjust the bolts on
the slide plate (beneath the splitting wedge) as follows
to eliminate the excess; space between the wedge plate
and the beam. See figure 18.

Page 12
Hex Bolts
Bolts
FIGURE 18.
• Loosen the three hex bolts on top of the slide plate
(beneath the splitting wedge).
• Back the two adjustment bolts on the side of the slide
plate out slowly until the wedge assembly will slide
on the beam. Tighten the lock nuts securely against
the base of the slide plate to hold the bolts in this
position.
• Retighten the three hex bolts on top of the slide plate.
Start engine and allow to warm for five minutes.
With throttle in FAST position, close needle valve
clockwise (). until engine Starts to lose speed
(lean mixture). Then slowly open needle valve
counterclockwise () until engine JUST BEGINS
to run unevenly. This mixture should be rich enough
for best performance under load.
Place throttle control in IDLE position:
a.
If engine idles, no further adjustment is
necessary.
b.
If engine idles too fast, turn idle speed adjusting
screw counterclockwise ( ) until slower speed
is obtained.
c. If engine dies, turn idle speed adjusting screw 'A
turn clockwise (/^ ). Place throttle control in
FAST position and restart engine.
d. Move throttle control to IDLE position. If engine
does not idle, repeat step c.
• Test the engine by splitting. If engine tends to stall
or die out, it usually indicates that the mixture is
slightly lean and it may be necessary to open ( f~\ )
the needle valve slightly to provide a richer mixture.
This richer mixture may cause a slight unevenness
in idling.
CARBURETOR ADJUSTMENT
WARNING: IF ANY ADJUSTMENTS ARE
MADE TO THE ENGINE WHILE THE
A
Minor carburetor adjustment may be required to com
pensate for differences in fuel, temperature, altitude or
load.
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 AP
PLICATIONS AND CONDITIONS.
Never attempt to change maximum engine speed. It
is pre-set at the factory and shouid 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 needle valve (see figure 19) clockwise
() finger tight only. Forcing may cause damage.
Then open 1V2 turns counterclockwise ( ).
ENGINE IS RUNNING (e.g. CAR
BURETOR), KEEP CLEAR OF ALL MOV
ING PARTS. BE CAREFUL OF HEATED
SURFACES AND MUFFLER.

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 fluid in-
WIRE BEFORE PERFORMING ANY
MAINTENANCE OR ADJUSTMENTS.

to a suitable container. Refill using only Dexron II
automatic transmission fluid, as instructed in the “In
itial Preparation” section of this manual, page 9. Also,
make certain to change the hydraulic filter.
Capacity is VA pints. Refer to “Gas and Oil Fill-Up”
on page 9.
• Replace oil fill plug.
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. Con
taminants in the fluid will damage the hydraulic
components. (Should be performed by your SEARS
Service Center.
WARNING: USE EXTREME CAUTION
WHEN WORKING WITH KEROSENE, AS
A
IT IS AN EXTREMELY FLAMMABLE
FLUID.
HYDRAULIC FILTER
Change the hydraulic filter every 50 hours of operation.
Use only a 10 micron hydraulic filter. Order part number
723-0405.
BEAM AND SPLiniNG WEDGE
Lubricate both sides of the beam where it contacts the
splitting wedge with engine oil before each use to ob
tain years of service. However, normal wear will occur.
The wedge plate on the log splitter is designed so the
gibs on the side of the wedge plate can be easily re
moved and rotated and/or turned over for even wear.
Make certain to readjust the adjustment bolts so wedge
moves freely, but no excess space exists between the
wedge plate and beam.
HOSE CLAMPS
Check the hose clamps on the suction hose (attached
to bottom of the pump) for proper tightness before each
use. Check the hose clamps on the return hose at least
once a season.
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 performance.
Never run your engine without air cleaner complete
ly assembled.
TO SERVICE AIR CLEANER:
Clean cartridge at three month intervals or every 25
hours, whichever occurs first. See figure 20. Service
more often under dusty conditions.
• Loosen screws and tilt cover as illustrated.
• Carfeully remove pre-cleaner and cartridge.
• Clean cartridge by tapping gently on a flat surface.
If very dirty, replace cartridge and pre-cleaner or
clean as follows;
a. Wash in a low or non-sudsing detergent and
warm water solution. CAUTION: Do not use
petroleum solvents such as kerosene to clean
cartridge.
b. Rinse thoroughly with flowing water from inside
out until water is clear.
c. Allow cartridge to stand and air dry thoroughly
before using. DO NOT OIL CARTRIDGE OR
PRE-CLEANER. DO NOT USE PRESSURIZED
AIR TO CLEAN OR DRY CARTRIDGE.
• Install cartridge and pre-cleaner. Then close cover
and fasten screws securely.

ENGINE LUBRICATION
Your four-cycle engine will normally consume some oil;
therefore, check engine oil level regularly—approxi
mately 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
even with the oil fill (refer to figure 12). Change engine
oil after the first five hours of operation, and every
twenty-five hours thereafter.
• Drain oil while engine is warm.
a. Remove oil drain plug. Refer to figure 12. Catch
oil in a suitable container.
b. When engine is drained of all oil, replace drain
plug securely.
• Refill with fresh oil. Above 32°, use oil labeled SAE
30W or 10W30. Below 32°, use oil labeled 5W20.

SPARK PLUG
The spark plug should be cleaned and the gap reset
to .030" at least once a season or every 50 hours of
operation. See figure 22. Spark plug replacement is
recommended at the start of each season. Refer to
engine parts list for correct spark plug type.
NOTE: Do not blast clean spark plug. Spark plug
should be cleaned by scraping or wire brushing and
washing with a commercial solvent.
When replacing the flexible pump coupling, proceed
as follows.
• Place the coupling half onto the engine shaft. Make
certain there is clearance between the coupling half
and the engine. Tighten the set screw.
• Mount the pump onto the coupling support bracket.
Tighten securely.
• Carefully slide coupling half onto pump shaft (make
certain set screw is loose). Slide the key into place
on the shaft.
• Install the nylon “spider” insert into coupling half on
the engine shaft.
• Place the coupling shield in position on the hex bolts.
Rotate the keyway on the pump shaft so it is toward
the bottom.
• Attach the coupling support bracket to the hex bolts,
carefully sliding the coupling half over the “spider”
insert. Secure coupling shield and coupling support
bracket with lock washers and hex nuts. Tighten
securely.
• Adjust the two coupling halves (steel) so there is be
tween .010" and .060" clearance between the two
halves (at least the thickness of a matchbook cover,
up to 1/16" maximum). See figure 23. Tighten the
set screw in the coupling half on the pump shaft.
MUFFLER
Do not operate the log splitter without a muffler or
tamper with the exhaust system. Damaged mufflers or
spark arresters could create a fire hazard. Inspect
periodically, and replace if necessary. If your engine
is equipped with a spark arrester screen assembly,
remove every 50 hours for cleaning and inspection.
Replace if damaged.
FLEXIBLE PUMP COUPLER
The flexible pump coupler is a nylon “spider” insert,
located between the pump and engine shaft. The align
ment is very critical. Over a period of time, the coupler
will harden and deteriorate. For a replacement flexible
pump coupler, order part number 717-0891.
NOTE: Make certain proper clearance is obtained
before tightening set screw.
PUMP
TIRE PRESSURE
Check sidewall of tire for manufacturer’s recommended
maximum tire pressure. If this information does not ap
pear on your tire, maximum tire pressure under any cir
cumstances is 30 p.s.i. Equal pressure should be
maintained on both tires.

INSTALLATION OF TIRE TO RIM
WARNING: THE FOLLOWING PRO
CEDURE MUST BE FOLLOWED WHEN
A
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. Ex
cessive pressure when seating beads may cause
tire/rim assembly to burst with force sufficient to
cause serious injury.
It is important to prevent gum deposits from forming
in essential fuel system parts such as the carburetor,
fuel hose or fuel 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.
To avoid engine problems, the fuel system should be
emptied before storage of 30 days or longer. Follow
these instructions.
• Drain the fuel tank. Start the engine, and let it run
until the fuel lines and carburetor are empty.

IMPORTANT INFORMATION FOR LOG SPLITTER USERS
ALWAYS:
Use clean fluid and check fluid level regularly
Use Dexron II Automatic Transmission Fluid
Use a filter (clean or replace regularly)
Use a breather cap on fluid reservoir
Keep end of reservoir return tube below fluid level
Make certain pump is mounted and aligned properly
Use a flexible “spider” type coupling between engine
and pump driveshafts
Keep hoses clear and unblocked
Bleed air out of hoses before operating
Flush and clean hydraulic system before startup after
any malfunction or servicing
Use “pipe dope” on all hydraulic fittings
Allow time for warmup before splitting wood
Prime the pump before initial startup by turning over
the engine with spark plug disconnected
Split wood with the grain (lengthwise) 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 will 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
withstand. 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 will void your warranty. If replacment 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.
Any other type of fluid must be approved by a direct factory representative.
5. The flexible pump coupler must be inspected regularly. Allowing the coupler to deteriorate will void your
warranty. 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. Do not overheat the hydraulic system. Excessive heat will destroy the hydraulic system with hardened 0-rings
and excessive friction.
9. 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.
10. Repair any leaks in hydaulic 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 warranty.

HOW YOUR LOG SPLITTER OPERATES
Cylinder Rod
r"
Reservoir
THE PUMP
A two-stage log splitter pump has one large and one
small gear section, using common inlet and outlet ports.
Below a preset pressure (called unloading pressure)
a check valve between the two gear sections allows
both flows to combine. Together, the two gear sections
create a large volume flow which produces rapid
cylinder movement under low load conditions.
Above unloading pressure, a pilot pressure line(which
simulates actual pressure at the cylinder) activates the
unloading valve, which causes the flow to bypass the
large gear section and return to the pump inlet area.
The small gear section is now operating alone, and will
generate the higher pressure necessary for the actual
log splitting operation.
The original factory setting for the unloading valve is
designed to provide maximum flow while remaining
below engine stalling load. Note: Splitting capability
is not affected by the setting of the unioading valve.
Do not attempt to adjust or reset it without a
pressure gauge (should be performed by an
authorized SEARS Serve Center only).
THE DIRECTIONAL VALVE AND CYLINDER
From the pump, oil flows to a four way, three position
directional valve. At the neutral position this valve
directs the flow back to the oil reservoir, bypassing the
cylinder. When the directional valve is directing the flow
to the back of the cylinder, the cylinder rod extends
quickly until it meets significant resistance. Upon
reaching unloading pressure, movement of the shaft

Low Pressure

will slow but will continue forward. If the pressure
reaches a preset maximum (called relief valve pressure)
the relief valve, located within the directional valve, will
allow the flow to bypass the cylinder and return to the
reservoir. This can happen when the cylinder rod meets
excessive resistance, or when it reaches the end of its
stroke and can move no farther.
Note: Never operate at relief valve pressure for more
than a few seconds.
When the directional valve is directing the flow to the
front of the cylinder, the rod will retract quickly since
it is encountering no resistance. The relief valve will
momentarily bypass the flow at the end of the return
stroke but the directional valve should then automatical
ly return to the neutral position, directing the flow direct
ly into the reservoir. This serves to protect the pump
from possible damage due to prolonged operation at
relief valve pressure.
Because of the potential for system damage, the relief
valve is carefully and precisely preset by the
manufacturer.
Note: The user should not attempt to adjust or
change the setting of the relief valve.
OPERATIONAL PROBLEMS
If you have trouble with your log splitter, please refer
to the Hydraulic Trouble Shooting Guide on page 19.
Note: Readjustment of valves or disassembly of
pump should be performed by your SEARS Service
Center only.
