1. Install the flat washer on the cap screw.
2. Slide cap screw and washer into one of three
mounting holes in the Adapter Plate. Choose the
hole based on where you want the brake air inlet
oriented. It is best to orient the inlet towards the
bottom of the brake to facilitate the drainage of any
moisture from the assembly.
NOTE: The bolt head should be facing away from the
Safety Chuck.
3. Apply Loctite®242 or equivalent to the screw
threads and secure nut to the Adapter Plate using
the recommended tightening torque listed in Table
2.
4. Mount the brake on the shaft following the instruc-
tions provided with the brake. Align the anti-rotation
slot with the head of the cap screws in the adapter
plate.
5. Secure the brake to the shaft allowing a minimum
amount of clearance between the brake and the
adapter plate.
NOTE: Make sure that the brake hub does not come
in contact with the low head cap screws used to
mount the plate to the Safety Chuck.
