RAISING THE MAST
1. Set up and level the unit. Refer to
.
WARNING
The unit must be leveled with
the outriggers extended before
raising the mast. The
outriggers must remain
extended while the mast is up.
Failure to level the unit or
extend the outriggers will
severely reduce the stability
and could allow the unit to tip
and fall.
2. Remove mast cradle locking pin from mast cra-
dle (A).
3. Check the mast cables for excessive wear or
damage. Make sure the cables are properly cen-
tered in each pulley (B). Check the electrical
cord for damage.
WARNING
Do not start the unit if
insulation on the electrical
cord is cut or worn through.
Bare wires in contact with the
mast or frame may energize the
unit and cause electrocution.
Repair or replace a damaged
cord.
4. Make sure the area around the unit is clear
before raising the mast to the vertical position.
5. Remove the safety pin from the mast lock bar
(C). Using the handle for the lower mast winch
(D), raise the mast until it is vertical and the tab
on the mast is positioned into the mast lock. The
mast lock bar should snap into place automati-
cally. Secure the lock with the safety pin (E).

6. After the mast is up and locked into place, use the upper mast winch (F) to telescope the mast to the desired
height. Extend the mast slowly, making sure the electrical cord is extending at the top sections of the mast.
If, for any reason, the winch cable begins to develop slack or any of the mast sections get stuck,
STOP
IMMEDIATELY
and contact an authorized service center.
CAUTION
Do not extend the mast beyond the colored mark on the middle mast tube (G).
7. Rotate the mast by loosening the mast rotation knob at the bottom of the mast (H). Turn the mast until the
lights face in the desired direction and then tighten the mast rotation knob to secure the mast in position.
