NIGHT SCAN POWERLITE, POWERLITE XTREME, AND POWERLITE HDT
OPERATING INSTRUCTIONS
Mast Tip Over Hazard! Mast tip over could result in death or serious injury. Before operation, be
certain mounting structure is capable of resisting forces generated from all loading and
environmental conditions, including, but not limited to, mast size and weight, payload and cable
size and weight, payload sail area, wind speed, guy line arrangement, support bracket or roof
line location, and base plate assembly. Do not operate in wind speed conditions exceeding the
maximum rated wind speed. Do not operate on slopes exceeding the maximum deployment
angle. Do not install a payload that exceeds the maximum payload lifting capacity of mast. Do not
install a payload with the center of gravity offset from mast centerline exceeding the maximum
allowed offset. Stand clear of mast and mast payload during operation. Be certain mast is level
and secure before and during installation, operation, and maintenance.
Falling Objects from Mast Hazard! Wear a protective hard hat when working on mast or
situated near mast operating area while mast is extending, retracting or deployed in any position
above the nested position. Improperly secured payload or mast components, ice formations, etc.
could be dislodged from mast and fall. Be sure the payload is properly installed and secured.
Relocation/Driving Hazard! Do not relocate the system during operation or while mast is
extended to any height above the nested position or powered up. Do not move vehicle until mast
has been securely nested and isolated from power. Power-up and operate mast only if the
vehicle is stationary and securely parked with the parking brake properly applied. Do not put
mast in service or operate without the vehicle interlock warning circuit or magnetic warning kit
installed to provide confirmation mast is nested prior to moving the vehicle. Contact The Will-Burt
Company Engineering for special on-the-move situations for military only use on specialized
products.
Burst Hazard! For pneumatically operated masts, do not operate without the over-pressure
safety valve installed. Keep personnel clear of safety valve exhaust direction. Do not exceed the
maximum rated pressure of mast. If the mast air pressure is not fully discharged prior to
removing air hoses, a rapid release of air pressure will occur requiring hearing and eye
protection.
Payload Lifting Hazard - Intended Use! The mast is intended to lift a specific payload for
lighting, surveillance or communication use only. Any other use without written consent is
prohibited and could cause death or serious injury. Do not use mast to lift personnel. Do not
exceed specified payload capacity. Large payload wind sail areas can reduce payload capacity.
Consult The Will-Burt Company engineering.
Read Operating Instructions! Read and observe the operating instructions. Non-observance of
the instructions, operation which is not in accordance with use as prescribed in the instructions,
wrong installation or incorrect handling can seriously affect the safety of operators and
machinery. Adhere to the safety instructions when carrying out any activity relating to the Night
Scan Powerlite, Night Scan Powerlite Xtreme, and Night Scan HDT.
