When the hand wheel (32) is turned anti-clockwise, a passage is opened between the discharge
connection and the oil container allowing the pressure to be released.
OIL LEVEL
Place the pump on a horizontal surface, remove filler cap (45) from the oil tank. Fill-up with the
recommended grade of oil until the level is approx. 20mm from the bottom of the filler hole.
BLEEDING
Place the pump on a bench or similar, with the pump head slightly inclined downwards and the
ram on the floor standing on its pressure head. Pump up to approx. half its stroke and leave to
stand for a few minutes. Allow the ram to retract very slowly. Repeat this operation a few times
until all the oil has been bled from the system. In order to bleed the pump system separately,
pump with the hand wheel (no. 32) fully open.
FAULT DIAGNOSIS
FULL PRESSURE CANNOT BE REACHED:
Discharge or intake balls do not seal tightly
Remove the gauge so that the balls (9, 11 and 13) are accessible. Minor damage to the ball
seats can be remedied by tapping the ball home with a light hammer blow.
IMPORTANT! Use a punch made of soft material that will not damage the ball.
Impurities in the oil
Disassemble and clean the pump.
Relief valve incorrectly adjusted
Remove reservoir (44) to adjust the relief valve (36). Clockwise to increase pressure. Anti-
clockwise to decrease pressure. Do not attempt to test the relief valve outside of the
reservoir
Release not tightened or ball damaged
Check Hand wheel (32) is tight. Check screw (31) if damaged replace.
Oil level low
Top up following above instructions.
Air in pump
Bleed the pump following the instructions above.
PUMP LEAKING OIL
Clean the pump. Locate any visible leakage
Check:-
1. That all screws are securely tightened
2. That the seals are intact.
3. That the sealing surfaces on the seals are undamaged.
4. That any damage, such as cracks, deformations and dirt particle are removed
CAUTION: Make certain that all those using the equipment have the necessary training.
