  followtheinstructionsbelowfollingthehydraulictank.Refertoyourengineowner’smanualforinformationonaddingoil.
The hydraulic reservoir must be lled with oil before operation. Use only clean oil and take care to prevent dirt from entering the hydraulic
reservoir. Fill the hydraulic tank with approximately 3.5 to 4.0 gallons of hydraulic uid
After the hydraulic reservoir and the engine crankcase are lled with oil, start the engine. The hydraulic pump should prime itself. With the
engine running, move the hydraulic valve lever toward the foot plate. This will cause the cylinder to extend and expel air. When the cylinder
is fully extended, retract it. Repeat this procedure several times. An erratic movement of the cylinder indicates that there is still air in the
system. Add about 2.0 to 2.5 gallons more. Continue to add uid until it registers in the “OK” range on the dipstick.The total capacity of the
hydraulic system is 6.5 gallons. NOTE: If the tank is overlled it will tend to expel oil from the breather cap when the cylinder is retracted.
Cycle the cylinder again until it has a constant speed indicating that all air has been expelled.
ENGINE OIL RECOMMENDATIONS (Honda GX270)
NOTE: Follow the instructions in Honda engine owner’s manual for lling.
For temperatures above 40 degrees F use an SAE 30W oil. Using mutigrade oil may increase oil consumption. Using SAE 30W oil below 40 degrees
F will resuilt in hard starting and possible engine bore damage.For temperatures below 40 degrees F use an SAE 10W-30 or SAE 5W-30 oil. Oil
capacity is about 1.16 quart (1.1 liter).
STARTING INSTRUCTIONS (Honda GX270)
ReferalsototheEngineOperatingandMaintenanceInstructionsmanualforyourlogsplitter.
1) Move the fuel valve lever to the ON position.
2) To start a cold engine move the choke lever to the CLOSED position. To restart a warm engine leave the choke lever in the OPEN
position.
3) Move the throttle lever away from the MIN position, about 1/3 of the way toward the MAX position.
4) Turn the engine switch to the ON position.
5) Operate the starter (recoil starter). Pull the starter grip lightly until you feel resistance, then pull briskly. Return the starter grip gently.
Do not allow the starter grip to snap back against the engine. Return it gently to prevent damage to the starter.
STOPPING THE ENGINE
To stop the engine in an emergency, simply turn the engine switch to the OFF position. Under normal consitions, use the following procedure.
1) Move the throttle lever to the MIN position.
2) Turn the engine switch to the OFF position.

STOPPING THE ENGINE
1) If possible, remove the load.
2) Move the throttle control to the “SLOW” or “LOW” idle position.
3) Turn key switch or on/off switch to “OFF.” Move throttle to “STOP” position if equipped.
4) Close the fuel shut-off valve.
ENGINE OIL RECOMMENDATIONS (Kohler CH395)
For temperatures above 32 degrees F use an 10W-30 oil. For temperatures above 50 degrees F use an SAE 30 oil. For temperatures below 32
degrees F use an SAE 5W-20 or SAE 5W-30 oil. Oil capacity is about 1.16 quart (1.1 liter).

ENGINE OIL RECOMMENDATIONS (Briggs & Stratton 1450)
NOTE: Follow the instructions in your Briggs & Stratton engine owner’s manual for lling.
For temperatures above 40 degrees F use an SAE 30W oil. Using mutigrade oil may increase oil consumption. Using SAE 30W oil below 40
degrees F will resuilt in hard starting and possible engine bore damage.For temperatures below 40 degrees F use an SAE 10W-30 or SAE 5W-30
oil. Oil capacity is about 1.16 quart (1.1 liter).

CAUTION:
NOTE: The engine maximum governed speed is preset at the factory at 3600 RPM no load speed. When splitting wood the throttle
should be set at the maximum speed to develop the horsepower required for the pump.
TURN FUEL SHUT OFF VALVE TO THE “OFF” POSITION PRIOR TO TOWING.FAILURE TO DO SO MAY RESULT IN
FLOODING THE ENGINE.
OPERATION
WARNING:Seesafetyinformationrelatedtooperationofthelogsplitterinthesafetysectionofthismanual.Makesurethatyouhavethe
 recommendedpersonalprotectiveequipmentdescribedonpage1.
1) Set up the log splitter in a clear, level area and block the wheels. Make sure that the suction port on the tank is always on the lower side
of the log splitter.
2) For horizontal operation place a log on the beam against the foot plate. Make sure the the log is securely on the foot plate and up against the
beam.To split wood in the vertical position, release the beam assembly latch located near the front end of the beam. Carefully tilt the beam
up until the foot plate is sitting squarely on the ground and the log splitter is stable. Place the log on the foot plate up against the beam. When
the beam is returned to the horizontal position make sure the beam latch is securely locked down.
3) With the engine running, depress the valve handle so that the cylinder will drive the wedge into the log. Extend the cylinder until the log splits or to
the end of its stroke. If the log has not completely split after the cylinder has reached the end of its extension, retract the cylinder.
IMPORTANT: Leaving the valve in the “actuate” position at the end of the stroke may damage the pump. Always use extra care when splitting
logs with unsquare ends.
NOTE: For operation in wooded areas, obtain a spark arrestor for the exhaust system. See the engine operating and maintenance manual and
check with your authorized Honda, Briggs & Stratton or Kohler service center. See also Fire Prevention on page 5 of this manual.
IMPORTANT: TO EXTEND THE LIFE OF THE HYDRAULIC CYLINDER, AVOID “BOTTOMING OUT” WEDGE PLATE TO THE FOOT

MAINTENANCE
1) Consult the operating and maintenance instructions of the engine manufacturer for engine care and maintenance.
2) Always check the oil level of the hydraulic reservoir before operation. Operating the log splitter without an adequate oil supply will cause
severe damage to the pump.
3) Change the oil lter after the rst 25 hours of operation. Thereafter, change the oil lter every 100 hours or seasonally, whichever comes rst.
4) To drain the hydraulic oil, loosen the clamp on the hose coming from the tting on the bottom of the tank. It is located just to the right of the oil
lter.
5) If the wedge becomes dull or nicked, it can be removed and sharpened. Remove the 1/2 in. diameter bolt that connects the wedge to the cylinder
hose from the valve. The hose from the valve may need to be removed. Carefully lift the cylinder to allow the wedge to slide forward. The wedge
can now be lifted off and sharpened.

6) Clean the breather cap after 25 hours of operation. Clean it more often when operated in dusty conditions. To clean, remove the breather cap
from the tank and ush with kerosene or liquid detergent to remove the dirt.
7) See also Repair and Maintenance Safety on page 4 of this manual.
8) All replacement parts must meet manufacturer’s specications.
