As normal wear occurs and there is excessive “play” 
between the wedge and beam, adjust the bolts on the 
side of the wedge assembly to eliminate excess space 
between the wedge and the beam. See Figure 15.

•

Loosen the jam nuts on the two adjustment bolts on 
the side of the wedge. 

•

Turn the adjustment bolts in until snug and then 
back them off slowly until the wedge assembly will 
slide on the beam.

•

Tighten the jam nuts securely against the side of 
the wedge to hold the adjustment bolts in this 
position.

Periodically remove and replace the “gibs” (spacers) 
between the wedge assembly and the back plate.
See Figure 15.

NOTE: The gibs may be rotated and/or turned over for
even wear.

•

Loosen the lock nuts under each back plate and 
slide the gibs out.

•

Turn or replace the gibs.

•

Reassemble the back plate and secure with the 
lock washers and lock nuts.

•

Readjust the bolts on the side of the wedge 
assembly. 

1.

Failure to maintain proper fluid level in reservoir 

2.

Changing the relief valve setting or pressure 
adjustment of control valve without proper 
knowledge and instruction from the factory 

3.

Disassembling the pump 

4.

Use of incorrect hydraulic fluid 

5.

Allowing the flexible pump coupler to deteriorate 
without proper and regular inspection

6.

Lack of lubrication or improper lubrication of the 
beam or unit

7.

Improper adjustment of splitting wedge

8.

Excessive heating of the hydraulic system

9.

Attempting to start unit in temperatures under 20°F 
without pre-heating fluid in reservoir

10. Unattended leaks in hydraulic system 

•

Check the hydraulic fluid level in the log splitter 
reservoir tank before each use. 

•

Maintain fluid level within the range specified on the 
dipstick at all times. 

•

Change the hydraulic fluid in the reservoir every 
100 hours of operation. 

•

Disconnect the suction hose from the bottom of the 
reservoir tank and drain the fluid into a suitable 
container. Refill using only Dexron III automatic 
transmission fluid or 10W AW hydraulic fluid.

NOTE:  Please dispose of used hydraulic fluid and
engine oil at approved recycling centers only.

•

Since contaminants in fluid may damage the 
hydraulic components, you will have to drain the 
fluid and flush the reservoir tank and hoses with 

Do not at any time make any 

adjustments without first stopping engine, 
disconnecting spark plug wire, and grounding it 
against the engine.

Before cleaning, lubricating, 

repairing, or inspecting, disengage the control 
lever and stop engine. Disconnect the spark 
plug wire and ground it against the engine to 
prevent unintended starting.

Higher pressure could cause 

the hoses to burst, cylinder to rupture, and 
intense fluid to be released, which could result 
in serious personal injury.
