Raising The Mast - Generac Power Systems Magnum MLT4200 Operating Manual

7. Before raising the mast, it may be necessary to adjust the lamps. The lamps may be adjusted up, down, left or
right by loosening the wing nuts on the trunnion (H) and aiming them in the desired direction. Tighten the hardware
completely and make sure the lamps are connected to the junction box (J).

RAISING THE MAST

1. Set up and level the unit. Refer to
Up" on page 14.
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 cradle (A).
3. Check the mast cables for excessive wear or dam-
age. Make sure the cables are properly centered 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 automatically. 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.
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 knob.
Never raise or lower the mast while the unit is operating. Never remove the safety pin or
release the mast lock while the mast is up. Releasing the lock will cause the mast to fall.
