As soon as installers put new door hardware in place, maintenance planners should begin setting up a comprehensive inspection routine to ensure a long, trouble-free performance life. Some hardware — for example, closers and operators on main access doors that cycle hundreds of times an hour — requires daily inspection.
But to ensure top performance, they also require continuous cleaning, periodic lubrication, and minor adjustments to the sweep speed. This approach can ensure minimal interruption to occupants' activities, and it can result in a more secure environment and cost-effective maintenance than if technicians tie up the entrance during major repairs after an operator or other hardware fails.
Door hardware's long-term performance life depends on proactive and comprehensive inspection and maintenance. The first step in such an effort is for technicians to inspect installations for early signs of trouble. They include:
Upon detecting these and other minor problems, technicians can take universal actions designed to avoid major problems. They include:
Finally, it is always good practice to use a hardware manufacturer's recommended maintenance procedures and frequencies.
