1.Turn the mast extension winch counterclockwise, and observe that the mast begins to lower.

2.Continue turning the winch counterclockwise until the mast has been fully retracted (slack in the cable).

Stowing the Mast to Horizontal Position

TURNING ON THE LAMPS

The main circuit breaker (25 amps) and 4 lamp circuit breakers (10 amps each) are located on the upper control panel (Figure 18). Each lamp has a 10-amp circuit breaker.

1.Place the main circuit breaker (Figure 18) on the control panel to the ON position.

Refer to Figure 17 for the location of components:

Refer to Figure 17 for the location of components.

1.With the mast in the deployed position (vertical), unscrew the mast rotation locking knob to release the mast for rotation.

2.Grip the mast rotation handles and rotate the mast until the lamps are facing the desired direction.

3.When the lamps are facing the desired direction, tighten the mast rotation lock knob to lock the mast in place.

Figure 18. Control Panel Circuit Breakers

2.Set lamp circuit breaker #1 on the control panel to the ON position.

3.Wait a few minutes for the ballast to activate. Observe that lamp #1 is ON.

4.Repeat steps 2 and 3 for lamps 2 through 4.

5.If all the lamp circuit breakers are in the ON position (up), then all of the lights should be on.

6.If any of the lamps are not on, refer to the troubleshooting section of this manual.

7.Close all cabinet doors.

NOTICE

NEVER operate the light tower with the engine compartment doors open. Operation with the doors open may cause insufficient cooling to the unit, and damage may result.
