Raising The Mast - Generac Power Systems MAGNUM MTT15 Operating Manual

RAISING THE MAST

1. Set up and level the unit. Refer to
Up" on page 16.
WARNING
The unit must be leveled before raising
the mast. Failure to level the unit will
severely reduce the stability and could
allow the unit to tip and fall.
2. Remove the mast cradle locking pin from the 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. The mast can be rotated 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.
