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:
ƒ Using an alternative air source insert it directly into the push-in fitting on top of the
clamp cylinder.
ƒ Turn on and then off.
ƒ If the exhaust for this alternative air source is good, then the cylinder should retract at a
normal rate.
ƒ 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:
ƒ 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)
