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 16 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 16 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.
OperatiOn
Lowering the mast
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
Refer to Figure 16 for the location of components:
1. Remove the mast lock/release pin to allow the mast
section to be lowered to the horizontal position. Pull
out the mast lock handle to unlatch.
2. Turn the vertical mast winch counterclockwise and
observe that mast begins to approach the horizontal
position. The mast lock handle can now be released.
3. Continue turning the vertical mast winch in the
counterclockwise direction. As the mast approaches
the mast cradle support, pull the retaining pin and
then the cradle lock/release pin to allow the mast to
rest in the cradle.
4. Once the mast is resting in the mast cradle support,
insert the cradle lock/release pin and secure with
retaining pin to keep mast in place.
Rotating the mast
To change the direction that the lamps are facing, the mast
can be rotated.
Refer to Figure 16 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.
