3. Check the 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 around the unit is clear before
raising the mast to 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. Do not extend past the
colored mark (G).
IMPORTANT NOTE: Contact a GMASD immediately
if the mast hangs up or the winch cable develops
slack.
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.
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.
