2. See Figure 3-3. Remove the mast cradle locking
pin from the mast cradle (A).
3. Check both sets of mast cables for excessive wear
or damage. Verify the cables are properly centered
in each pulley (B). Check the electrical cord for
damage.
4. Verify the area behind the unit is clear before
raising the mast to the vertical position.
5. Remove the safety pin (C) from the mast lock bar
(D). Using the handle for the lower mast winch (E),
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.
6. Secure the lock with the safety pin (F).
7. After the mast is up and locked into place, use the
upper mast winch (G) to telescope the tower to the
desired height. Extend the mast slowly, making
sure that the electrical cord is extending at the top
sections of the mast. Do not extend past the
colored mark (H).
IMPORTANT NOTE: Contact a Generac Mobile Prod-
ucts Authorized Service Dealer immediately if the
mast hangs up or the winch cable develops slack.
NOTE: For flagger station use, the tower should extend
20 ft. (6.10 m), which is approximately 20 turns of the
winch.
8. The mast can be rotated by loosening the locking
knob at the bottom of the mast (I). Turn the mast
until the lights face in the desired direction and
then tighten the knob.
WARNING
Tipping hazard. Do not extend the mast beyond the
colored mark on the second mast section. The unit
can become unstable and tip or fall, causing injury.
WARNING
Personal Injury. Stop immediately if the mast hangs
up or the winch cable develops slack. Excess slack
could cause the mast to collapse, resulting in personal
injury or equipment damage.
WARNING
Personal injury or equipment damage. Do not raise
or lower the mast while the unit is operating.
Doing so can break the lenses and cause the
lamps to shatter.
IMPORTANT NOTE: Never remove the safety pin or
mast lock while the tower is up. Releasing the lock
will cause the tower to fall.
