The clamp is releasing slowly
If the machine cycles at a normal rate, but the clamp is releasing slowly then a few tests need to
be run to determine a cause and a solution.
Figure 14
The clamp cylinder airline may have developed a crimp or leak in the hose.
Solution Steps:
Using an alternative air source insert it directly into the push-in fitting on top of the
clamp cylinder.
Turn on and then off.
If the exhaust for this alternative air source is good, then the cylinder should retract at a
normal rate.
If not then the cylinder needs to be replaced. (Figure 14)
The pilot valve located in the control box may have an obstruction in the
exhaust port.
Solution Steps:
Open the rear door of the machine and locate the small, white plastic barb to
the left of the yellow (or black) knob. (Figure 15)
