6.3 Product opens or closes abruptly
Possible cause Corrective action
Too little grease in the mechanical guiding
areas.
Clean and lubricate product.
Maintenance [

Compressed air lines blocked. Check compressed air lines of damage.
Mounting surface is not sufficiently flat. Check the evenness of the mounting surface.
One-way flow control valve is missing or ad-
justet incorrectly.
Install and adjust one-way flow control
valve.
Loading too large. Check permissible weight and length of the
gripper fingers.
6.4 Product does not achieve the opening and closing times?
Possible cause Corrective action
Compressed air lines are not installed
optimally.
If present: Open the flow control couplings
on the product to the maximum that the
movement of the jaws occurs without boun-
cing and hitting.
Check compressed air lines.
Inner diameters of compressed air lines are
of sufficient size in relation to compressed
air consumption.
Flow rate of valve is sufficiently large relat-
ive to the compressed air consumption.
If you still cannot achieve the open and close
times mentioned in the latest catalog, we re-
commend the use of quick-air-vent-valves
directly at the product.
Compressed air can escape. Check seals, if necessary, disassemble the
product and replace seals.
Component part defective. Replace component or send it to SCHUNK
for repair.
Too much grease in the mechanical move-
ment space.
Clean and lubricate product.
