adjustments or repairs.

Maintenance

Engine

Refer to the separate 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 and 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. 

Disconnect the suction hose from the bottom of the 

reservoir tank, and allow the fluid to drain into container.

3. 

Carefully unthread the inlet filter and clean it with 

penetrating oil. See Figure 6-1.

4. 

Allow the fluid to drain into a suitable container.

5. 

Reinsert the filter and reconnect the hose. Fill the reservoir 

as instructed in the Assembly & Set-Up section. 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. Check the engine oil level. Refill if necessary.

6. 

Maintain the fluid level within the range specified on the 

dipstick at all times.

NOTE: 

Always dispose of used hydraulic fluid and engine 

oil at approved recycling centers only.

7. 

Contaminants in 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.

Hydraulic Filter

Change the hydraulic filter every 50 hours of operation. Use only 

a 10 micron hydraulic filter. Order part number 723-0405.

Beam and Splitting Wedge

Lubricate both sides of the beam (where it comes into contact 

with the splitting wedge), before each use, with engine oil.

Hose Clamps

Before each use, check if the hose clamps on the suction hose 

(attached to the side of the pump) are tight. Check the hose 

clamps on the return hose at least once a season.

Flexible Pump Coupler

The flexible pump coupler is a nylon “spider” insert, located 

between the pump and the engine shaft. Over time, the coupler 

will harden and deteriorate. If you detect vibration or noise 

coming from the area between the engine and the pump contact 

an authorized service dealer. If the coupler fails completely, you 

will experience a loss of power.
