OPERATING INSTRUCTIONS
Emergency Stow! Using the emergency stow button causes the actuator to lower mast without
regard to any faults, switches, or system interlocks. It is totally up to the operator to ensure safe
operation during an emergency stow attempt. When using the emergency stow button, normal
operation switches are disabled. The mast can be overdriven into saddle and cause damage to
the unit. Disengage the emergency stow button when the payload reaches the saddle and is
tight. Do not drive mast beyond this position.
Manual Tilt! If manually tilting mast, make sure all power has been disconnected from the sys-
tem prior to manually lowering mast to avoid unexpected motion and/or damaging mast compo-
nents.
Safety Instruction - Motion on Power Interruption or Emergency Stop! Mast uses a normally
open air control valve. If power is lost or turned off or the emergency stop is activated while mast
is extended, mast will begin releasing air pressure and retracting at a controlled rate until power
is restored or mast fully retracts. Masts that fold down will not initiate any tilt motion.
