If pump is to be transported after use, replace the transit plug in tank.
WARNING: DO NOT RELY ON THE PUMP VALVE FOR POSITIVE LOAD HOLDING. IF IT IS REQUIRED TO
LOCK THE LOAD IN POSITION USE A MANUAL SHUT OFF VALVE IN THE CIRCUIT. NEVER WORK UNDER
A LOAD SUPPORTED ONLY BY HYDRAULIC MEANS.
FILLING WITH OIL.
Ensure cylinder is full retracted.
HP110: Position pump vertically with pump head downwards. Remove central plug on rear of pump and check oil
level using dipstick fitted to plug.
Use only Hi-Force HF032 oil.
BLEEDING THE HYDRAULIC SYSTEM.
Connect a cylinder to the pump. Position the cylinder below the level of the pump with its pressure ports
uppermost. Ensure the bleed screw on the pump is open. Operate the cylinder 3-4 times over its full stroke and all
air should be forced back to the pump reservoir.
Warning
: when using a small cylinder with long hoses it is
possible that air can remain trapped in the hose if the volume of the hose is greater than the volume of the cylinder.
In this case the bleeding must be carried out using a shorter hose before use.
See Figure 4.
