Maintenance
1. Check that the motor mounting bolts are tight.
2. Remove the brush covers (where applicable), blow out the brush holders, check the brushes for
wear, and reinstall the covers.
3. Inspect the operator belts for the following:
a. Cracks or glazing
b. Even wear on both sides of the belt
c. The belts are not bottomed out in the grooves
d. Proper tension (belt slippage).
The following guidelines apply when testing, adjusting, or replacing belts:
• Ideal tension is the lowest tension at which the belt will not slip at peak load.
• All belts in the set should be tested for equal tension by pushing each belt down at the
midpoint between the pulleys. (Typical deflection is 3/8" with 10 lbf applied).
• If belts require tensioning, check the sheave alignment with a straight edge.
• If belts are replaced on multi-groove sheaves, change the belts as a matched set.
4. Check that all of the linkage bolts are tight.
5. Remove the door operator cover, rotate the door operator by hand, and check the operation of
the DOL and DCL sensors.
6. Check the operation of the gate switch, and make sure that it is adjusted per code.
7. Use a burnishing tool or clean rough paper, and clean the gate switch contacts (if necessary).
8. Replace the door operator cover.
9. Check for excessive bearing wear.
