4: RECOMMENDED MAINTENANCE

The AST2225-3 transfer switch assembly has been designed to require minimum

attention under all environmental conditions normally encountered. All sliding and

bearing surfaces are inherently self-lubricating due to the combination of materials used

and therefore should not be lubricated, thus preventing any accumulation of dust and grit

at these locations. The gear-motor is also lubricated for the life of the unit, and requires

no attention.

Periodically inspect all terminals (load, line and control), and all fasteners for tightness.

Test the transfer switch operation upon initial installation, in both the motor and manual

modes. Periodically check for freedom of movement of the mechanism, hidden dirt or

corrosion, and any excessive wear on the mechanical operating parts. Clean or replace

parts when necessary.

Do not attempt to remove the arm assembly by loosening the pivot screw and lock nut.

Instead, remove the four screws holding the pivot bracket in position and lift the

assembly clear. This will facilitate any adjustment of the pivot screw and lock nut that

may be required after extended service.
