Maintenance
WARNING! Do not make any adjustments
without stopping the engine,
disconnecting the spark plug wire,
grounding it against the engine and
relieving the hydraulic system pressure.
Always wear safety glasses during
operation or while performing any
adjustments or repairs.
Engine
Refer to the Engine Operator’s Manual packed with
your log splitter for all engine maintenance.
Tire Pressure
The max recommended operating pressure is 30
psi. Do not, under any circumstances, exceed the
manufacturer’s recommended psi. Maintain equal
pressure on all tires.
WARNING! Excessive pressure when
seating beads may cause the tire/rim
assembly to burst with force sufficient to
cause serious injury. Refer to the sidewall
of the tire for recommended pressure.
Hydraulic Fluid
Check the hydraulic fluid level in the log splitter
reservoir tank before each use. Maintain the fluid level
within the range specified on the dipstick at all times.
Change the hydraulic fluid in the reservoir every 100
hours of operation. The filter should also be changed
with each hydraulic fluid change. Follow the steps
below:
1. Place a suitable oil collection container under
the tank.
2. If your engine has a horizontal engine set-up
shown in Figure 5-1, refer to Figure 5-1 for
changing the hydraulic fluid.

3. If your engine has a vertical set-up shown in
Figure 5-2, refer to Figure 5-2 for changing the
hydraulic fluid.

4. Disconnect the suction hose from the bottom
of the reservoir tank. See Figure 5-1 for
horizontal engines or Figure 5-2 for vertical
engines.
5. Carefully un-thread the inlet filter and clean it
with penetrating oil. See Figure 5-3.

6. Allow the fluid to drain into a suitable
container.
NOTE: The reservoir tank has a capacity of 3
gallons and the entire hydraulic system has a
capacity of approximately 4.7 gallons.
7. Reinstall the cylinder, hoses, pumps, filter
and suction hose. Tighten the hose clamps to
50-60 in-lbs.
8. Check the fluid level using the dipstick. Do not
overfill.
NOTE: Approved fluids include Shell Tellus®
S2 M 32 Hydraulic Fluid, Dexron® III / Mercon®
automatic transmission fluid, Pro-Select™ AW-32
Hydraulic Oil or 10WAW-ISO viscosity grade 32
hydraulic oil. It is recommended that fluids not
be mixed.
9. Replace the vented dipstick securely,
tightening it until the top of the threads are
flush with top of the pipe.
10. Disconnect the spark plug and prime the pump
by pulling the recoil starter as far as it will go.
Repeat approximately 10 times.
11. Reconnect the spark plug wire and start the
engine following the instructions in the Engine
Operator’s manual.
12. Use the control handle to engage the wedge
to the farthest extended position. Then retract
the wedge.
13. If necessary, refill the reservoir within range
marked on the dipstick. See Figure 5-4.

14. Extend and retract the wedge 12 complete
cycles to remove trapped air in the system (the
system is “self-bleeding”).
WARNING! Much of the original fluid has
been drawn into the cylinder and hoses.
Make certain to refill the reservoir to
prevent damage to the hydraulic pump.
Failure to refill the tank will void the log
splitter’s warranty.
NOTE: Some fluid may overflow from the vent
plug as the system builds heat and the fluid
expands and seeks a balanced level. Do not
operate the log splitter without the proper
amount of fluid in the reservoir tank.
15. Maintain the fluid level within the range
specified on the dipstick at all times. When
checking the fluid, always make sure to tighten
the dipstick until the top of the threads are flush
with the top of the pipe.
NOTE: Always dispose of any used hydraulic
fluid and engine oil at approved recycling
centers only.
16. Contaminants in the fluid may damage the
hydraulic components. Flushing the reservoir
tank and hoses with kerosene whenever
service is performed on the tank, hydraulic
pump or valve is recommended. Contact an
authorized service dealer.
