MAINTENANCE
CAUTION: Before attempting to service or remove
any components, make certain that the power is
disconnected and that the load is completely removed,
secured or blocked to prevent injury or property
damage.
Wear Adjustment
CAUTION: Load to be removed or blocked. Brake may
be inoperative during this procedure.
Before air gap “A” reaches .100”, adjustment is required. Any
delay in adjusting the magnet air gap will result in eventual
loss of torque. Refer to Fig. 3.
1. To adjust, remove cover locknuts (22) and cover (20)
to expose square head wear adjusting screws (15H)
and expose magnet air gap “A”.
2. Measure air gap “A” using 3/8” to 1/2” wide feeler
gauge. (Measure at center of magnet.)
3. Turn two square head adjusting screws (15H) until
air gap “A” measures:
.045/.050 for 1 disc models
.050/.055 for 2 disc models
.060/.065 for 3 disc models
.060/.065 for 4 disc models
Air gap should be the same on both sides.
