1.5.4 Adjust the Air Gap of the Brake

Rated air gap Z grows with the friction. In order to there is sufficient braking torque, the air gap

must be set before it reaches to the maximum value. The air gap can be adjusted by several

times. When the thickness of brake pad becomes the minimum value(see the specification table

below), the brake pad must be replaced.

Once the air gap reaches the top value, the brake might not be released and the brake pad

would be burn out. It will also cause the decrease of braking force and the retention and the

would be burn out. It will also cause the decrease of braking force and the retention and the
noise increase and even big accidents. It is prominent to do the periodical inspection and adjust

noise increase and even big accidents. It is prominent to do the periodical inspection and adjust

the air gap. Disconnect the power. Through adjusting 3 hollow bolts (8) and the mounting bolts of

stator (9), set the air gap between stator (1) and armature (2) to the rated Z by a feeler

gauge.Ensure air gap at all directions are same.
