Before each use, check the following:
• Place log splitter on a firm, level surface. For verti-
cal operation, putl the locking rod out and pivot it
down to release the beam. Place the beam in the
vertical position, See figure 7.
• Remove the vent plug and check the fluid level,
See figure 12. Fluid level should be 1-1/2" to 2"
from the top of the tank.
NOTE: Before initial use or first time use after stor-
age, be certain to fill the reservoir as instructed in next
section.
IMPORTANT: Reservoir tank must be full as in-
structed. Low fluid level will damage the pump and
void your warranty.
• Lubricate the beam area where the splitting
wedge will slide with engine oil (DO NOT USE
GREASE). Make certain to oil both front and back
of the beam face.
• Fill fuel tank as instructed previously.
• Attach spark plug wire and cover to spark plug.
See figure 11.
FIGURE 12.
&
WARNING: DO NOT OPERATE THE LOG
SPLITTER WITHOUT THE PROPER
AMOUNT OF TRANSMISSION FLUID IN
THE RESERVOIR TANK.
BEFOREINITIAL USE
Fill the reservoir tank as follows.
• Remove reservoir vent plug, See figure 12. Using
Dexron II automatic transmission fluid, fill reservoir
to the top. Replace vent plug securely.
NOTE: Total capacity of system is approximately 4
gallons.
• 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.
• 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 itsown level.

TENANCE OR ADJUSTMENTS.
Check all nuts, bolts and hose clamps periodically to
make certain they are tightened securely.
LOGSPLITTER
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
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 will damage the hydraulic
components (should be performed by your SEARS
Service Center).
WARNING: USE EXTREME CAUTION
WHEN WORKING WITH KEROSENE, AS
IT IS AN EXTREMELY FLAMMABLE
FLUID.

FIGURE 14.
Periodically remove and replace the "gibs" (spacers)
between the wedge plate and the back plate as fol-
lows.
NOTE: If desired, the gibs may be rotated and/or
turned over for even wear.
• Remove the center bolt on top of the wedge plate.
Slide the gib plate out. See figure 14.
• Remove and replace the gibs. Reassemble the gib
plate, making certain flat washer is in place under the
gib plate.
• Readjust the bolts on the side of the wedge plate as
instructed previously.
HYDRAULIC FILTER
Change the hydraulic filter every 50 hours of opera-
tion. Use only a 10 micron hydraulic filter. Order part
number 723-0405.
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 wil! 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
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 < 32°F "' = Warmer
13
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.
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.
Retainer Cover ,ase

Pre-Cleaner
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, tf very dirty, replace. Do not oi! 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.

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 yearry check-up by your local Sears Service
Center isa good way to make certain your log splitter
will provide maximum performance for the next sea-
son.
LOGSPLI'R'ER
• Clean the log splitter thoroughly.
• Wipe unit with an oiled rag to prevent rust, espe-
cially wedge and beam.
• The tongue can be removed and reattached in an

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 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 fuet 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 slowry
to distribute oil. Replace spark plug.
OTHER
• Do not store gasoline from one season to another.
• Replace your gasoline can if your can startsto rust.
Rust and/or dirtin yourgasoline willcause problems.
• Store unit in a clean, dry area.
NOTE: If storing in an unventilated or metal storage
shed, be certain to rustproof the equipment by coating
with a light oil or silicone.

CARBURETORADJUSTMENT
WARNING: IF ANY ADJUSTMENTS ARE
MADE TO THE ENGINE WHILE THE
ENGINE IS RUNNING (E.G. CARBURE-
TOR), KEEP CLEAR OF ALL MOVING
PARTS. BE CAREFUL OF HEATED SUR-
FACES AND MUFFLER.
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 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 (v_) and hold
against idle speed adjusting screw. Turn idle speed
adjusting screw unlil engine is running at 1750
RPM
• Turn idle mixture valve clockwise (f'q) (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, tf it does not, carburetor should be read-
justed, usually to a slightly richer mixture.
ENGINESPEED
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.
WARNING: EXCESSIVE PRESSURE
(OVER 30 p.s.t.) WHEN SEATING BEADS
MAY CAUSE TIRE/RIM ASSEMBLY TO
BURST WITH FORCE SUFFICIENT TO
CAUSE SERIOUS INJURY.
