LOAD BRAKE ADJUSTMENT
Brake device should be checked and cleaned of all dust and oil every three months.
The air gap of the brake is as standard 0.078 inches. The gap should be measured
between the brake drum and pull rotor. The gap adjustment is done by turning the
adjustment nut (refer to diagram above). Using a feeler gauge, measure the gap. Adjust
until set. If the gap will not set, disassemble the motor brake and inspect all motor brake
parts and the order. If necessary, replace the brake drum or motor cover.
If the electric chain hoist is mounted to an electric trolley, it is important to inspect both
brakes- Trolley and Hoist.
