NOTE: 

This Operator’s Manual covers several models. Features may vary 

by model. Not all features in this manual are applicable to all models and 

the model depicted may differ from yours.

WARNING! 

Do not — at any time — make any 

adjustments without first stopping engine, disconnecting 

spark plug and grounding it against the engine. Always 

wear safety glasses during operation or while performing 

any adjustments or repairs.

Maintenance

Engine

Refer to the Engine Operator’s Manual for all engine maintenance 

instructions.

Tire Pressure

See the sidewall of the tire for recommended pressure. Do not, under 

any circumstances, exceed manufacturer’s recommended psi. Maintain 

equal pressure on all tires.

WARNING! 

Excessive pressure when seating beads 

may cause tire/rim assembly to burst with force sufficient 

to cause serious injury. Refer to the sidewall of tire for 

recommended pressure.

Hydraulic Fluid & Inlet Filter

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. 

If your engine has a horizontal engine set-up shown in Figure 7-1, 

see Figure 7-1 for changing the hydraulic fluid. If your engine has a 

vertical set-up shown in Figure 7-2, see Figure 7-2 for changing the 

hydraulic fluid.

Carefully un-thread the inlet filter and clean it with penetrating oil. 

See Figure 6-3.

5. 

Allow the fluid to drain into a suitable container.

NOTE: 

The reservoir tank of the 27/28 ton units has a capacity 

of 3 gallons and the entire hydraulic system has a capacity of 

approximately 4.7 gallons. The reservoir tank of the 33 ton units 

has a capacity of 5 gallons and the entire hydraulic system has a 

capacity of approximately 7 gallons.
