Problem
Potential Cause
Solution
No vacuum pressure
Improperly connected tubing
At each brass barbed fitting, make sure the end of the tube has
been advanced past at least three barbs.
Loose fittings
Check all brass fittings and tighten with a
1/2" wrench, if necessary.
Compressed or kinked tubing
Make sure nothing is squeezing the tubing and that the
tubing has no kinks.
Hole or other damage in tubing
Cut away damaged section and reconnect or install
replacement hose (58991, sold separately).
Ball valve is stuck open by debris
Turn pod upside down and push on valve until debris falls out.
Dusty workpiece or
Vacuum Clamp Pods
Wipe, vacuum or blow away dust from workpiece and pods.
Uneven mounting surface
Make sure the Vacuum Clamp Pods are mounted on a flat surface.
Uneven workpiece
If workpiece is warped, try to reposition. If workpiece is severely
warped, another hold-down method might be required.
Porous material or defect (such as a
knot or crack) in the workpiece
Try to reposition the workpiece. If workpiece is excessively
porous, another hold-down method might be required.
Improper positioning of workpiece
Make sure the workpiece doesn’t overhang the Vacuum
Clamp Pods too far.
Make sure that the workpiece covers the entire top surface of
all Vacuum Clamp Pods to create a tight seal.
Damaged gasket on pod
Replace with included extra gasket. A 4-pack of replacement
gaskets also is available (51231, sold separately).
