QEAM STRAP DRIVE MAST OPERATOR’S MANUAL
viii TP-4619601-D
October 2023
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

October 2023
Crush Hazard - Mast Failure! Do not stand directly beneath mast or its payload. Be certain the
payload is properly installed and secured.
Entanglement Hazard! Tangled cables can cause equipment damage. Ensure payload cables,
Nycoil®, trip lines, guy lines or other cables are not tangled and are free to pay out as mast is
deployed. Cables that get tangled or snagged on mast or other objects can cause mast tubes to
lurch upward suddenly when the cable is freed. This can cause damage to mast and lead to
mast separation if repeatedly allowed to continue.
Health and Safety Hazard while Cleaning! Solvent used to clean parts is potentially
dangerous. Avoid inhalation of fumes and prolonged contact to skin.
Fire Hazard Solvent! Cleaning solvent, used for maintenance, is flammable and can be
explosive. Do not smoke near solvent. Use cleaning solvent in a well-ventilated area. Keep
cleaning solvent away from ignition sources. Always store cleaning solvent in the proper marked
container and in a proper location.
Bright Light Radiation Hazard! For systems equipped with scene lighting or look-up lights, do
not look directly into lights when they are illuminated. Temporary impairment or permanent
vision damage could occur.
Personnel Freezing/Burn Hazard! If the system is equipped with lights, make sure the lights
are completely cool before attempting to clean the lens, replace bulbs or perform maintenance.
Wear gloves to protect from contact with exposed metal that may be at extremes of hot and cold
temperatures from sun or cold outdoor exposure.
Mast Extension Hazard - Obstruction! Extending mast into obstructions could result in death
or serious injury and could render mast inoperable and partially extended. Before applying
power and operating mast, be certain there is sufficient clearance above and to all sides of the
expected location of the fully extended mast and payload. Keep all persons clear of mast and
mast extension. Do not lean directly over mast. Locate the operator station such that the
operator has a clear view of the operating space of mast and payload prior to deployment to
avoid contact with overhead objects.

QEAM STRAP DRIVE MAST OPERATOR’S MANUAL
TP-4619601-D xi

Frozen Water Hazard! Water freezing inside mast or air fittings may render mast inoperable
and cause major equipment damage such as tube deformation. Ensure water is free to exit at
the base of mast. Open drain cock when mast is not in operation. The drain cock shall be
installed at the lowest position in the pneumatic system. If mounted internally in a vehicle or
structure, direct the draining water to a suitable location. Cover locking masts when not in use to
limit water ingress. Non-locking masts stored outdoors should be covered if possible. A cover is
available from The Will-Burt Company.
Lubrication! Do not lubricate the exterior of mast moving tubes. The lubricant will attract dust
and other environmental contaminants into mast.
Equipment Damage - Forces! Before unloading the system, be certain the unloading region is
capable of resisting forces generated from unloading the system including but not limited to
system weight. Ensure the unloading region is level and has sufficient room and strength to hold
the system. If the unloading region is incapable of meeting the requirements of the system,
damage to the system and/or unloading region could occur.
Equipment Damage - Support Bracket! For masts using an upper support bracket, do not
over-tighten mast support bracket. Over-tightening may damage the Base Tube causing mast
tubes to stick.
Mast and Payload Access! The operator must provide safe means to access mast and
payload during installation, removal and maintenance.
Tripping Hazard! Cables, trip lines, guy lines and guy anchors can be hard to see during and
after installation. Any equipment posing trip hazards should be clearly marked.
Lifting Hazard! Depending on the mast model, the mast weighs up to 275 lbs. (125 kg). Always
observe weight lift limits.
Lubrication! Do not apply oil or grease to the mast. Lubricants will attract sand/dirt and may
lead to premature wear and/or damage to the strap.

QEAM STRAP DRIVE MAST OPERATOR’S MANUAL

needs may vary. If necessary, contact The Will-Burt Company for additional details.
The exact configuration of the mast may vary. For detailed information on the locations of
components in your system, see the drawings that shipped with the system.
Telescoping Mast: The telescoping mast is the structure used to raise the payload to an
operational level. It consists of a base tube, a top tube, and intermediate tubes that extend and
retract.
Strap Mast Tool Kit: The Strap Mast Tool Kit is a kit that is mainly used during emergency
nesting procedures and when repairing the mast strap. It contains vice grips, an Allen wrench
set, a manual brake tool, and other components.
Gin Pole / Winch Assembly (Optional): The lift winch kit is used to raise the mast and payload
from the horizontal position to the vertical position. It is also used to lower the mast and payload
from the vertical position to the horizontal position. The lift winch and Gin Pole stabilize the mast
and payload during installation and retrieval.
Antenna Adaptor (Optional): The antenna adaptor attaches to the top of the mast and is used
to secure and support the payload during operation.
Optional Stake Puller: The optional stake puller is used to remove stakes. It can be used on
different sizes of stakes including the 650mm and 850mm stakes. The stake puller top handle is
shipped separate from the bottom base.
