If operating manually (typically an emergency operation when power is not available):

operation.
b. Disconnect the air hose at the base of the mast.
c. Connect a hand pump to the base of the mast.

9. Select “HOLD”. The “HOLD/EXHAUST” switch is a maintained switch and will keep its
position.
10. Select and hold “UP” to extend the mast. The “UP” function on the “UP/DOWN” switch is
momentary. Continue to hold “UP” until the mast is fully extended.
Maintain visual contact throughout extension to avoid overhead obstructions and to ensure
none of the cables become tangled or snag on anything. Do not exceed the maximum
recommended operating pressure of 35 psi at any time.

air from the mast.
