CHECK THE OIL LEVEL
1. Turn the release valve counter clockwise to allow the ram to fully
retract. It may be necessary to apply force to the saddle to lower
the ram.
2. Remove the inspection plate.
3. With the jack in the level position remove the oil fill plug. Stand
the jack in the vertical position with the handle socket down. The
oil should be level with the bottom of the fill hole. If not, top up
but do not overfill. Always fill with new, clean hydraulic jack oil.
4. Replace fill plug and inspection plate.
5. Check jack operation.
6. Purge air from the system as required.
SYSTEM AIR PURGE
1. Turn the release valve counter clockwise one full turn to open.
2. Pump the handle eight full strokes.
3. Turn release valve clockwise to close the valve.
4. Pump the handle until the ram reaches maximum height and con-
tinue to pump several times to remove air trapped in the ram.
5. Carefully and slowly pinch the oil fill plug to release trapped air.
6. Turn the release valve counter clockwise one full turn and lower
the ram to the lowest position. Use force on the saddle if neces-
sary.
7. Turn the release valve clockwise to the closed position and check
for proper pump action. It may be necessary to perform the
above more than once to ensure all the trapped air is evacuated.
