RAISING THE TOWER WITH THE OPTIONAL ELECTRIC WINCH
1. Set up and level the trailer as described on page 12, and follow
steps 1-3 on page 13.
2. Remove the safety pin from the mast lock bar (R).
3. Press the lower winch control toggle switch upward to raise mast
into the vertical position (S). Hold switch until the mast lock is
engaged. The mast lock bar should snap into place automati-
cally.
Note: On light towers equippedwith the electric winch
option, a limit switch on the mast tube will disconnect power to
the lower electric winch to prevent deadheading the winch.
4. Secure the lock with the safety pin (T).
5. Press and hold the upper winch control toggle switch upward to
telescope the mast to desired height (U). Extend the mast
slowly, making sure that the coiled 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 tower sections get stuck,
STOP IMMEDIATELY and contact an authorized servicecenter.
CAUTION
Do not extend the mast beyond
the colored mark on top of the
lower mast section (V). On light
towers equipped with the electric
winch option, a limit switch on the
main mast section will disconnect
power to the upper electric winch
to prevent over extending the
mast.
6. The mast can be rotated by loosening the locking knob at the
bottom of the mast (W). Turn the mast until the lights face in the
desired direction andthen tighten the knob.
WARNING
Never raise or lower the mast
while the unit is operating!
Never remove the safety pin or
mast lock while the tower is up.
Releasing the lock will cause
the mast to fall.
