Check that all guards protecting the function switches or locks are in place. Ensure that all function controls and switches return to the "off" or neutral position when released.

Raise the tower base boom to approximately 40 degrees, then lower the tower boom back to the below horizontal position. While raising and lowering the tower boom assembly, observe the position of the upright. Ensure that the upright remains vertical relative to the chassis.

Check that all machine functions are disabled when the emergency stop button is pushed in.

Check for proper operation of the auxiliary power and manual descent system (if equipped). Operate each function control to ensure proper operation.
