Quick--Disconnect
Coupling
Ram
INSPECTION/PROBLEM
POSSIBLE SOLUTION
Inspect for cracks, gouges, nicks, or galling on the
“C”--Head or where the “C”--Head contacts dies.
Check to see if the upper die retaining pin does not
hold the stationary die in place.
Check to see if the upper die release button sticks
(it should normally move in and out easily when
moderate pressure is applied).
Inspect for evidence of cracks, gouges, nicks, or
galling.
Inspect for oil leaks between the cylinder and
coupling.
Check to see if the coupling sticks to the cylinder (it
should normally turn on and off freely when moderate
pressure is applied with applied with a wrench).
The coupling mates hard or won’t mate or release, or
it leaks oil, or it sticks at the hose connection.
Inspect the ram in the Power “ON” (ram advanced)
position for evidence of galling, cracks, or oil leaks
between the ram and the cylinder.
Check to see if the lower die retaining pin does not
hold the moving die in place.
Check to see if the lower die release button sticks
(it should normally move in and out easily when
moderate pressure is applied).
Inspect the ram in the Power “OFF” (ram retracted)
position to ensure that the ram returns freely to its
original position.

For oil leaks and a sticky coupling, tighten or replace
the coupling
Replace coupling.
If there are cracks or leaks, return the tool for repair
