Briggs & Stratton 71018, 71021 Maintenance, Specifications, UL 1008 Listed Transfer Switch Model

Maintenance

The transfer switch is designed to be maintenance free under normal usage. However, inspection and maintenance checks should be made on a regular basis. Maintenance will consist mainly of keeping the transfer switch clean.

Visual inspections should be done at least once a month. Access to transfer switch must not be obstructed. Keep

3 feet (1 m) clearance around transfer switch. Check for an accumulation of dirt, moisture and/or corrosion on and

around the enclosure, loose parts/hardware, cracks and/or discoloration to insulation, and damaged or discolored components.

Exercise the transfer switch at least once every three months as described in section Testing the Automatic Transfer Switch unless a power outage occurs and home generator system has gone through an automatic sequence. Allow generator to run for at least 30 minutes.

Contact a licensed electrical professional to inspect and clean the inside of your transfer switch at least once a year.
