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
Oil leaking around the ram?
Using the table plates secure the ram under pressure (4-6 ton) for 1 hour. This will put pressure on the main seal causing
it to stretch and properly seal. If this does not work the seals more than likely need to be changed. Press may lose
pressure during the 1-hour time period,
Ram is jerky or sluggish?
With the valve open, repeatedly pump the handle to allow air to be released from the lines. If this does not work may need
to replace the O-rings and seals in the pump.
Ram does not return to the starting position at the top of the stroke?
Open and close the valve multiple times. If no progress has been made, the return spring may be broken and in need of
replacing.
What should I do if the pump will not build pressure?
Check and see if the release valve is in the closed position. Check oil fluid level. If low, add fluid and bleed to maximize
efficiency. May need to change the O-rings and seals in the pump.
My pressure gauge on the press is leaking?
Apply thread sealer (Teflon Tape) following the flow of the threads on the gauge. Do not apply Teflon Tape against the
direction of the threads, this will not allow the gauge to seal properly.
Leaking oil around the hoses?
Make sure to check all fittings. Tighten if they are loose, and check for any damage on the hose itself.
The press will not reach the maximum allowable tonnage?
Check the valve to make sure it is fully in the closed position. You may have to bleed the system to maximize efficiency.
May need to replace the seals in the head and the pump.
The press will not hold pressure?
Check the valve and make sure it is in the closed position. Some cases, press will naturally bleed itself. If not, bleed the
system. Important: the press itself is not designed to hold pressure for any amount of time. The press is designed to
create pressure up to 10 tons and then retract.
