Replace the hydraulic oil in the log splitter after every 150 

hours of use. Take the following steps to replace the oil.

1.  Make sure all moving parts are stopped and the log split-

ter is unplugged.

2.  Remove oil drain bolt and dipstick. Make sure bleed screw 

is closed tight.  (SEE FIGURE 9)

3.  Turn the log splitter on the support leg side over using a 

one gallon or larger capacity container to drain the hy-

draulic oil.  (SEE FIGURE 10)

4.  Turn the log splitter on the motor side.  

5.  Refill with 3.75 quarts of fresh hydraulic oil.

6.  While keeping the log splitter vertical, clean the surface 

of dipstick on the oil drain bolt and put it back into the oil 

tank.

7.  Make sure the level of the refilled oil is between the two 

grooves around the dipstick.

8.  Clean the oil drain bolt before re-threading it back in. 

Make sure the bolt is tightened to avoid leakage before 

placing the log splitter horizontally.  

Periodically check oil level to ensure it is between the two 

grooves around the dipstick. If the level is below the lower 

limit, fill until level is correct.

The following hydraulic oils, or equivalent, are recommended 

for the log splitter’s hydraulic pump:

SHELL Tellus 22

MOBIL DTE 11

ARA Vitam GF 22

BP Energol HLP-HM 22 

When the log splitter wedge becomes dull and/or worn, 

sharpen the wedge using a fine-toothed file and smooth any 

burrs or crushed areas along the cutting edge.
