Removal of Air
The hydraulic system, when connected for the first
time, will have air in the system. The air must be
removed for safety and proper operation. Air can
generally be removed from the system by fully
advancing and retracting the hydraulic cylinder
several times. When the trapped air is removed from
the hydraulic circuit, the cylinders will advance and
retract smoothly. Sluggish cylinder action is usually
the first sign of air in the system.
WARNING: Do not exceed cylinder
capacity or stroke.
Adjusting Relief Valve
