Hydraulic Fluid
Always wear safety gog-
gles when servicing the
hydraulic system.
Figure 24. Draining hydraulic fluid.
Inspect for burnt-smelling or tan-colored water
contaminated hydraulic fluid. If contaminated,
replace tank breather, clean tank filter/strainer,
flush system, and replace fluid.
4. When the tank is empty, remove the bolts
the rest of the way and then remove the tank
screen.
5. Pull the tank vent off.
6. Clean the tank vent with mineral spirits and
let air dry.
7. Clean the tank screen with mineral spirits and
blow dry with compressed air.
8. Inspect the screen and tank vent for any
holes and replace if any damage exists.
9. Reach into the tank and wipe out as much
residual fluid and contaminants as possible.
We highly recommend that the tank be
cleaned out with a pressure washer or steam
cleaner and fully dried with compressed air
for best results.
10. Reinstall the tank screen, rubber gasket, and
hose.
11. Fill the tank with 2.5 gallons of hydraulic fluid
and reinstall the tank vent cap.
To change the hydraulic fluid:
1. Chock the log splitter wheels to prevent it
from rolling.
2. Place a 3-gallon or larger drain pan under the
tank filter screen cover.
3. Loosen the screen cover hex bolts and care-
fully dislodge the cover slightly so the hydrau-
lic fluid fills the drain pan (
Figure 24).
Note: Do not lose the rubber gaasket in the
drain pan.
