Is the airgap set to the specified value?
Since the clutch and brake are equipped with an auto gap device, they can be kept
constant at the specified clearance for the entire life. Do not subject it to vibration or
shock. Measure the airgaps uniformly at 3 or more circumferences.
Is there any abnormal noise?
Pay attention to the abnormal noise generated by the clutch and brake.
Is there an abnormal high temperature?
Make sure that the clutch and brake do not generate abnormal heat.
Are the mounting screws loose?
Check that the unit mounting screws and components are not loose.
3) Inspection of Wear Amount
Check the wear limit line on a regular basis.
The friction surface gradually wears over time, but the air gap is kept constant by the
action of the auto gap device, so no adjustment is necessary.
Occasionally remove abrasion powder using air or the like.
In the case of normal wear, the amount of wear can be used up to the limit value shown
in Table 4. If the wear limit line (see Fig. 6) is exceeded, the product will reach the end of
its life, so replace the unit with a new one.
