3. Lubricate the surface of slide rail with a general-
purpose grease (Figure 24). This will help to prevent
wear between the slide plates and the slide rail.
4. Pull the spark plug wire off the spark plug (Figure 25).
This prevents the engine from starting until the
hydraulic pump and cylinder are completely filled with
fluid. Make sure the spark plug wire is held away from
the spark plug with string or other nonconductive
material.
5. Push the control valve handle to the forward position
(towards the front of the cylinder) (Figure 26). Have
another person pull the engine starter cord (about 15
times) until the cylinder piston moves forward. (Keep
everything away from the splitting wedge during this
step.)
NOTE: Extending the cylinder draws the hydraulic fluid
through the system and expels any trapped air in the
cylinder.
6. Check the fluid level in the hydraulic tank and add fluid
as needed. Replace and tighten the fill cap.
