Hydraulic Fluid Change
Tools needed:
• Screwdriver
• 10" crescent wrench
• Spark plug socket and Ratchet
1. Drain the head end of the cylinder.
a. Remove the spark plug wire and spark plug to help
reduce the back pressure on the engine and to prevent
it from starting.
NOTE: The total amount of hydraulic fluid in the system is
9.5 gallons.
b. Disconnect the return hose from the hydraulic fluid
filter housing and place it in a waste fluid container
(Figure 53). (Please properly dispose of the waste
hydraulic fluid per local regulations.)
c. Extend the cylinder by holding the hydraulic control
valve handle forward and have someone pull on the
engine’s pull start cord until fluid from the return line
stops flowing. This step drains the head end of the
cylinder.
2. Drain the hydraulic tank.
a. Place a waste fluid container under inlet hose (Figure
53).
b. Remove the inlet hose from the pump.
c. Slightly lower the front of the WOOD SPLITTER by
folding the leg assembly to completely drain the tank.
3 . Remove and replace the hydraulic fluid filter.
a. Remove the existing hydraulic fluid filter and properly
dispose of it (Figure 54).
b. Apply a thin coat of hydraulic fluid to the rubber seal of
the new hydraulic fluid filter.
c.
Screw the filter onto the filter head. Once the filter seal
makes contact with the filter head, turn it an additional
¾ turn. Hand-tighten only.
