Important Notice about Adjusting Cylinder Speed
Do not adjust the cylinders to speed up production.
The air cylinder timing is part of a well
tuned system of electronics, programming, and mechanics. Adjustment of the cylinders for speed
can cause unsatisfactory results, in-feed and out-feed problems, far marks in the corners of hinge
pockets, and flipping screws in Hoppers.
However, sometimes machine settling, mechanics be “broken in” may be cause to slightly adjust
extend and retraction speed.
If more than 1/2 turn on adjustment knobs are needed, call in a specialist or check with
KVAL customer service at 1-800-553-5825.
