WEAR ADJUSTMENT (See Figures 5 & 7)

When armature plate (12) touches bracket (5), closing gap

"B", adjustment for friction disc wear is required.

Figure 5. 60 Series H.L. Brake

12. To adjust, turn screws (16) clockwise until magnet gap

"A" reads .040" to .045" at narrowest gap, for 1 and 2

disc models and reads .050" to .055" at narrowest gap for

3 disc models. Any delay in adjusting gap will result in

eventual loss of torque.

TORQUE ADJUSTMENT (See Figure 7)

13. Brake is factory set for rated torque. To increase

stopping time and lower torque, turn locknuts (45)

counterclockwise. Each full turn decreases torque by

approximately 10%.

FRICTION DISC REPLACEMENT (See Figure 7)

14. When total wear on rotating friction disc (2) reaches

1/16", replace disc as follows. Loosen three mounting

screws (37), with release knob in release position, remove

operator assembly as a unit, spring (13), and stationary

disc (1).

15. Reassemble all parts in reverse order. Start all three of

the mounting screws (37), then turn two adjustment

screws (16) counterclockwise to allow the three operator

assembly mounting posts to seat against the bracket (5),

then tighten mounting screws. Readjust magnet gap, see

"Adjustment for Wear", paragraph 12.

MAGNET ASSEMBLY REPLACEMENT

(See Figures 5 & 7)

16. To replace magnet assembly, unscrew two flat head

screws (31), remove magnet assembly (25) with shoulder

nut (23) and rubber washer (24).

17. Replace complete magnet assembly (25) and reassemble

parts in reverse order.

18. Magnet will be noisy, if magnet faces are not parallel in

closed position. Turn pivot nut (15) until minimum noise

is obtained.

19. If manual release does not work properly after resetting

pivot nut, set magnet gap "A" to read .040" to .045" at

narrowest gap, for 1 and 2 disc models and .050" to .055"

at narrowest gap for 3 disc models. Turn release shaft

clockwise until it strikes roll pin (39), releasing brake.

20. Adjust locknut (14) and jam nut (21B) until magnet gap

"A" is .030" at center of magnet face width. Manual

release must be in release position for this measurement.
