How to Add Fluid to Hydraulic Pump:
1. Retract the ram that is connected to the pump.
2. Place the pump on a smooth, level surface so that that handle is in the up position.
3. Remove filler plug (small plug near the top).
4. Lift the plug end of the pump

of an inch off the ground to properly fill the reservoir.
5. Replace the plug to ensure quality sealing.
6. Reinstall pump on press.
7. Open the valve and pump continuously to properly bleed the system.
Trouble Shooting
Question:
Oil leaking around the ram?
Solution: Secure the ram under pressure for 1 hour. This is a cause of a bad seal.
Question:
Ram is jerky or sluggish?
Solution: With the valve open, repeatedly pump the handle to allow air to be released from the
lines.
Question:
Ram does not return to the starting position at the top of the stroke?
Solution: Open and close the valve multiple times. If no progress has been made, the return
spring may have failed.
Question:
What should I do if the pump will not build pressure?
Solution: Check and see if the valve is at the completely at the closed position.
Check oil fluid level. If low, add fluid and bleed to maximize efficiency.
Question:
The pressure gauge on the press is leaking.
Solution: Apply thread sealer (Teflon Tape) with the flow threads on the gauge. Do not apply the
Teflon Tape against the threads, this will not allow the gauge to seal properly.
Question:
Leaking oil around the hoses?
Solution: Make sure to check all fittings. Tighten if they are loose, and check for any
damage on the hose itself.
Question:
The press will not reach the maximum allowable tonnage?
Solution: Check the valve to make sure it is fully in the closed position. You may have to bleed
the system to maximize efficiency.
Question:
The press will not hold pressure?
Solution: Check the valve and make sure it is in the closed position. Some cases, press will
naturally bleed itself. If not, bleed the system.
