Extraction Truck Assembly
The extraction truck assembly requires visual inspection of hardware, lubrication and operations during routine maintenance.
With the controller outside the cell, verify all visible hardware tightness, including handles (8) and wheels (6). Wheels should rotate freely by hand movement. Replace
or tighten any missing or loose hardware.
With the controller outside the cell, rotate the racking screw as though racking the controller to the connect position. This process will expose surfaces inside the
truck that need to be inspected and lubricated. Apply grease "Moykote 33" to entire racking screw, pin and bushing surfaces. Inspect the position Release Shaft
(3), cell locking tabs (7) and secondary Locking Tab (1) for any damage. Return truck to disconnect position. As a precaution, do not operate the controller outside
the cell unless the truck is in the full disconnect position.
