2.As soon as the pin clears the travel position hole, release it and continue sliding out the outrigger. The pin must snap into the outrigger locking hole in the extended position.

3.After extending all outriggers, rotate all trailer jack stands into the foot down position, then turn the crank handle on the jackstands clockwise to lower it and level the light tower.

4.Check behind the light tower and make sure all personnel and objects are clear of the mast.

Deploying the Mast to Vertical Position

Refer to Figure 17 for the location of components:

1.To release the mast from the mast cradle support, pull the retaining pin out of the cradle lock/release pin. Pull the cradle lock/release pin. This will unlock the mast from the horizontal position.

2.Remove the mast lock/release pin before raising tower to the vertical position.

3.To place the mast in the vertical position, turn the vertical mast winch hand lever clockwise until the mast is pointing upwards at 90 degrees.

4.Once the mast is in the vertical position, insert the mast lock/release pin to prevent the mast from falling.

Raising the Mast

Once the tower mast has been locked into its vertical position, the mast can now be raised.The tower allows the lamps to be extended upwards in excess of 30 feet.

Refer to Figure 17 for location of components.

1.Turn the mast extension winch clockwise and observe that the mast begins to extend upwards.

2.Continue turning the winch in the clockwise direction until the desired height has been reached.

3.Release the winch. This winch is of the self-locking type. The tension on the cable will keep the mast in place.
