MAINTENANCE & ADJUSTMENTS
Regular maintenance is the way to ensure the best performance and long life of your machine. Please refer to this manual
and the engine manufacturer’s owner’s manual for maintenance procedures.
Engine
Refer to the Engine Operator’s manual packed in the hardware kit box of your log splitter for all engine maintenance
e.g. how to check and change the engine oil.
NOTE:
When draining oil from the engine on this log splitter, shield the hoses from any oil that may run down the frame
and drip onto the hoses. Thoroughly wipe any residual oil off the log splitter and hoses after completing service.
Tire Pressure
The tires are off-road tires. The max recommended operating pressure is 30 psi. Do not, under any circumstances,
exceed the manufacturer’s recommended psi. Maintain equal pressure on both tires.
Flexible Pump Coupler
The flexible pump coupler, located between the pump and the engine shaft, has a nylon “spider” insert. Over time, the
insert will harden and deteriorate. If you detect vibration or noise coming from the area between the engine and the pump,
contact an authorized dealer or Boss Industrial, Inc. Make sure to change a new coupler spider immediately when the
coupler spider fails completely, or you will experience a loss of hydraulic power.
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. Follow the steps below:
1. Place a suitable oil collection container under the tank.
2. Disconnect the oil drain plug from the bottom of the reservoir tank. See FIGURE 21.
3. Allow the fluid to drain into the container.
NOTE:
The reservoir tank has a capacity of 4 gallons of hydraulic fluid for 22 / 25 / 28 / 30 ton; and 5 gallons for 35
ton log splitter.
4. After draining, put the oil drain plug back in and tighten.
WARNING!
Do not make any adjustments without first stopping the engine, disconnecting the spark
plug wire and grounding it against the engine. Always wear safety glasses during operation or while
performing any adjustments or repairs.
!
WARNING!
Excessive pressure when seating beads may cause the tire/rim assembly to burst with
force sufficient to cause serious injury.
