Adjustment Procedure

WARNING: Lifting capacity decreases whenever vacuum switch is adjusted to

maintain lower vacuum level.

1) Using a 1/4" open-end wrench (as provided), turn the adjustment screw

about 1/6th turn at a time (approximately one flat of the screw head).

To maintain a

lower

vacuum level, turn the screw

clockwise

(when viewing

vacuum switch from end with electrical connectors).

To maintain a

higher

vacuum level, turn the screw

counter-clockwise

(when

viewing vacuum switch from end with electrical connectors).

2) Recheck the vacuum switch setting following each 1/6th turn of the

adjustment screw. In order to test the adjustment accurately,

release the vacuum pads completely before reapplying them to a

test surface.

When the vacuum switch is adjusted correctly, the vacuum pump turns off only

after

vacuum

increases to a level higher than the minimum lifting level; and the pump turns on again

before

vacuum decreases to a level lower than the minimum lifting level.
