ABB AMVAC - Truck

1VAL050601-MB Rev C
TRUCK:
The truck requires visual inspection of hardware, lubrication and operations during routine maintenance.
With the breaker outside the cell, verify all visible hardware tightness, including handles (9) and wheels (7). Wheels
should rotate freely by hand movement. Replace or tighten any missing or loose hardware.
With the breaker outside the cell, rotate the racking screw as though racking the breaker to the connect position. This
process will expose surfaces inside the truck that need to be inspected and lubricated. Lubricate the Racking Screw on-
ly. Inspect the Racking Screw (2), Position Release Shaft (3), breaker locking tabs (8), Secondary Locking Tab (1) for
any damage. Return truck to disconnect position. As a precaution, do not operate the breaker outside the cell unless
the truck is in the full disconnect position.
