MAINTENANCE
Recommended to replace hydraulic oil every 6 months of machine use. See "FILLING PRESS
WITH OIL" section for instructions.
LUBRICATION
• Keep all working parts of the press well-oiled for easier operation.
• Keep a light film of oil over the entire surface of the ram to prevent rust.
TROUBLESHOOTING
PUMP PACKING LEAKAGE
If oil leaks past the pump packing, tighten the pump packing nut (item 9) until the pump handle
moves with resistance, then slack off just enough to cause the handle to stay in position by
itself. After long periods of operation, it may be necessary to install new pump packings.
PRESS NOT HOLDING PRESSURE
This condition is nearly always caused by dirt under the pressure ball valve (item 2). See hand
pump assembly drawing.
Steps to fix:
1. Remove the reservoir drain plug and drain all oil out of the reservoir.
2. Remove parts: pipe plug (item 18), check valve spring (item 6) and ball valve (item 2)
then clean out the port hole and valve seat thoroughly.
3. Using a small piece of brass rod as a drift, tap on the brass rod lightly to seat the ball
valve in place.
4. Replace the spring and plug with extreme care to prevent dirt from entering.
5. Replace the drain plug and refill the reservoir with clean filtered oil.
