AIR IN LINE (CHANGING OUT HOSES OR CYLINDERS)
Air can be introduced if replacing the hydraulic hose or cylinder. This air can cause complete
failure of the resetting/reloading mechanism and must be bled.
•
Prior to air bleeding, check that manual pump is operational, with valve stem at MANUAL
and Quick-Connect disconnected. If lever has no, or little, resistance see manual for priming
hand pump. If OK, place valve stem at AUTOMATIC, reconnect hose and extend cylinder
fully.
•
CYLINDER without Bleeder Valve: To bleed air, first loosen the hose swivel connection at
cylinder, then use hand pump until no air is evident. Re-tighten hose.
•
CYLINDER with Bleeder Valve: A Bleeder port has been provided next to the oil inlet. Use
this port to bleed air when changing a hose or cylinder.

understand instructions prior to cylinder replacement!!! It is highly recommended that the
