The truck requires visual inspection of hardware, lubrication,
and operation during routine maintenance.

Wheels should rotate freely by hand movement. Replace or
tighten any missing or loose hardware.
With the circuit-breaker outside the cell, rotate the racking
screw as though racking the circuit-breaker to the Connect
position.
