4 Loosen the contact pad capscrews and nuts.
NOTE: It is not necessary to remove the capscrews
and nuts to insert the shims.
5 Install shims as required.
• Positive Camber – Install shims at the bottom and
middle of the pad to increase clamp force at the
bottom of the load.
NOTE: This will increase the clamp force
percentages on the lower spindles readout of the
4-Point Force Distribution Tester.
• Negative Camber – Install shims at the top and
middle of the pad to decrease clamp force at the
bottom of the load.
NOTE: This will increase the clamp force
percentages on the upper spindles readout of the
4-Point Force Distribution Tester.
CAUTION: Use an equal number of shims on each
contact pad. Pad camber must be the same on both
sides of the attachment for proper load handling.
