MAINTENANCE

WARNING

To avoid injury, always turn off the unit power switch before working on gate.

Regularly performance of preventive maintenance is essential for reliable system operation because it
corrects small problems before they turn into emergencies.  LiftMaster recommends performing
preventive maintenance every 6 to 12 months, depending upon gate usage.

  If the gate is installed in a private residence or small apartment house where usage is not

severe, yearly preventive maintenance is acceptable

  If the gate is installed in a high-traffic application, semi-annual preventive maintenance is

essential.

PREVENTIVE MAINTENANCE TASKS

1. 

Gate:

  must swing freely without any impediment.  Tighten set screws if loose 

!

.  Check hub,

grease if necessary.

2. 

Limit switches:

  contacts must bounce back rapidly when they are pressed and released.

3. 

Belt:

  Check for wear and tension (20 to 25 lbs.).  Adjust the AC motor up or down to set proper

tension.

4. 

Pulleys: 

 must all line up and be firmly secured to their shafts.  Tighten set screws if loose 

!

.

5. 

Gear Box:

  Check for no oil leakage around the bushings.  Do not oil gearbox.

6. 

Control board:

 Check for water damage or burned spots.  All connectors secured to the board.

7. 

Wiring:

  Check all wirings for any insulation damage.  Check for loose wire connections.

8. 

No Rust:

  Check for rust throughout the unit.  Check corners for water entrapment.

9. 

Fire Open: 

 Activate Fire department switch to verify emergency gate opening.

10. 

Gate Sense: 

 Check for the gate sensitivity (refer to Part 2, System Installation, paragraph J,

Gate Sensitivity Adjustments).

11. 

Power Fail Option:

 Check for proper operation (refer to Part 2, System Installation, paragraph

L, Power Fail Option Connection, item B, Power Fail Option Operation Test).

                                                                                                                                                            

NOTES:

 

!

: To prevent loosening, LOCTITE threadlocker 242 is applied.
