Trouble Shooting

There is a leak in the hydraulic system. See Trouble

Shooting.

Check to make sure the hydraulic power unit is

producing 2500 psi at 20-35 gpm.

Check that the HawkJaw is getting at least 100 psi air.

Check that the pump pressure compensator setting

is at 2500 psi.

Check that the hydraulic lterelementis not com-

pletely full of contaminants. If the red indicator button

on the hydraulic lter body pops up, change the lter

element. See Filter Maintenance.

There is an inner seal leak in the cylinder. Make sure

the HawkJaw rests on the rigoor. Shut down the

hydraulic power unit. Push the Grip button repeat-

edly to bleed all hydraulic pressure. Push in the “E”

stop button. Disconnect the Raise/Lower cylinder

Hanger Eye from the hanging cable. See Installation

& Drawings. Place the Raise/Lower cylinder Rod side

end on the rigoor. Pull out the “E” stop button.

Turn on the hydraulic power unit. Push in the Lower

button, and hold down the Lower button. While hold-

ing down the Lower button, check for Raise/Lower

cylinder piston seal integrity. Make sure no bodily

parts are in the extension path of the cylinder rod.

Slowly loosen the HawkJaw Rod side Leader hose.

Check for uidow. If there is a piston seal leak,

uid will ow with volume out of the Rod side leader

hose. Replace the seals. See Drawings. Replace the

cylinder if necessary. See Drawings. Push and hold

the Raise button. After the Raise/ Lower cylinder has

fully retracted, check for Raise/ Lower cylinder piston

seal integrity. Make sure no bodily parts are in the

extension path of the cylinder rod. Slowly loosen the

HawkJaw Cap side Leader hose. Check for uidow.

If there is a piston seal leak, uid will ow with vol-

ume out of the Cap side leader hose. Replace the seals.

See Drawings. Replace the cylinder if necessary. See

Hydraulic uid heats up.

The Raise/Lower Cylinder moves

slower than usual, or the HawkJaw

sinks while it hangs..
