Top Quality Doors is excited to announce the Shield Preventive Maintenance Program. This program is for home owners and companies that want to protect the investment in their property that a gate operator, telephone entry and access control system represent. 

The purpose of this program is to establish a consistent, scheduled maintenance for gate operators, telephone entry and access control systems. Customers that invest in a preventive maintenance program benefit from enhanced reliability and extended product life span. The Shield Preventive Maintenance (PM) Program has been designed for early detection of possible malfunctions and to reduce the potential downtime of a system that is expected to work 24/365. This early detection could prevent the concern that an unsecured home can cause as well as the added security expense for unsecured facility.

Top Quality Doors will design a customized Shield PM Program based on the number of components in your system, the expected daily use and the location of your property; regardless of who supplied and/or installed the system. Our certified technicians will service your system based on a standard 24-point checklist and the manufacturer’s recommendations. 

Our standard 24-point checklist includes:

1. Disconnect operator and check gate for proper operation.
2. Adjust and/or lubricate gate rollers and hinges.
3. Run operator while disconnected to test maximum run timer.
4. While testing maximum run timer, check motor for heating and balance.
5. Check oil in gear head (if so equipped) and fill if necessary.
6. Inspect belts for wear and tension.
7. Check clutch facing for wear and glazing.
8. Inspect brake, brake disc, and brake solenoid. Adjust if required.
9. Check key in intermediate shaft at brake (certain models).
10. Check and adjust chain tension. Observe if chain is drooping no more than 3” over entire length.
11. Inspect idler and drive sprockets for wear, wobble and alignment. Tighten set screws.
12. Operate and test manual disconnect.
13. Inspect electrical wire connections and relays.
14. Test power at rest and while operating gate.
15. Operate gate with operator and observe for unusual activities.
16. Adjust clutch and limit switches.
17. Check operator posts or mounting bolts for movement.
18. Inspect and tighten all mounting bolts, inside and out.

If repairs are determined to be needed, a written estimate of those repairs based on the current pricing will be provided for your approval. Upon approval of the estimate, our technicians will complete the repairs that your time and our truck inventory allow. Any repairs that cannot be completed after the Shield PM program scheduling will be scheduled by Top Quality Doors’ office with the customer.

For the safety of our customers and our technicians, Top Quality Doors will not perform the Shield PM program on any system that does not meet the UL 325 Vehicular Gate Standard. Top Quality Doors will provide a written estimate to bring the system into compliance. If this estimate is approved, we will make the suggested changes and then the system can be enrolled in the Shield PM Program.
