Trouble–Shooting
Air in the Hydraulic System:
■
Air in the hydraulic system may cause the lower blade from advancing or
cause it to advance slowly. To eject the air bubble from the hydraulic
circuit:
1. Position the tool upside-down in a vice with the pump handle in the open
position.
2. Unscrew the main handle from the body, then remove the reservoir filler
cap (HYCP-185, #55 / HYCP-240R. #45).
3. Pump the moving handle a few times to advance the ram.
4. Rotate the pump handle and close it to release the pressure in the
hydraulic circuit until the piston is fully retracted and the oil has returned
completely into the reservoir.
5. Repeat the process several times to assure that all air bubbles are
ejected.
6. Close the rubber reservoir and insert the the reservoir filler cap.
Reassemble the main handle.
Oil Refilling:
■
Check the oil reservoir every six months and make sure the reservoir is
full. To refill the oil reservoir, follow the steps above to disassemble the
tool. Do not use restored, used oil, or mix different kinds of oil.
