Manual Retraction! For powered masts, make sure all power sources have been disconnected
from the system prior to manually lowering mast to avoid unexpected start-up motion and/or
damage to mast.
Mast Lifting/Handling! Use extreme caution while lifting mast System and when mast System
is suspended to avoid injury and equipment damage. Be certain mast is properly secured using
at least two sling points at the center of gravity label. All operators should be aware of and
follow the applicable local, regional, and national standards and codes of practice for slinging
and transporting equipment. Never lift Mast System over people. Ensure lifting equipment
including, but not limited to, lifting straps and hoist, are capable of handling the forces generated
from lifting the system. Observe manufacturer instructions on lifting equipment.
Remove Payload! For mast systems shipped with no payload (customer installed payloads),
remove payload before performing maintenance on mast system. The Will-Burt Company
installed devices can remain installed.
Equipment Damage - Submerged! Do not submerge mast in liquid or operate the vehicle in a
fording situation that would result in a submerged mast.
Safety Instruction – Keep Clear! Keep personnel clear of the system during operation.
Safety Instruction - Potential Air Contaminants! If internally mounted in a vehicle, air from
mast and any accumulated water will discharge into the vehicle. Install appropriate drainage and
venting.
Fastener Vibration Hazard! Mast system and payload mounting hardware must include proper
means to resist vibration loosening such as thread-locking compound, locking hardware, or
equivalent. Use specified assembly torques appropriate for the fastener size.
Safety Instruction - Guy Anchors! For masts using Guy Lines, verify the Guy Anchor point
strength is adequate to support the Guy Line forces.
