Mast Extension Hazard - Obstruction! Do not deploy the mast if power lines are less than 80
ft. (24.4 m) from the center of the deployment site.
Mast Tip Over Hazard! Do not attempt to deploy or retrieve this mast when winds exceed 32
km/h / 20 mph.
Mast Deployment Hazard! Do not attempt to deploy the tripod on ground that slopes more than
2°. Do not attempt to deploy the mast on soft or loose soil. The base plate and guy stakes could
become unstable under wind loading and cause the mast to fall. The mast must be vertical
before deployment. Adjust guy lines as required until the bubble level indicates the mast is
vertical.
Safety Instruction - Guy Stakes! Use guy stakes to secure tripod and mast. For masts 8 ft /
2.4 m to 40 ft / 12.2 m tall and smaller payloads, one stake per tripod leg plate may be sufficient.
For masts taller than 40 ft / 12.2 m, two stakes are required on each tripod leg plate. Be mindful
of buried cables when staking the mast. Always follow guy stake removal instructions to avoid
injury and/or guy stake damage.
The following list contains reasonably foreseeable misuses of the mast system according to EN
ISO 12100 5.3.2. These uses shall be avoided:
Operating the mast with an obstruction in the functional space that prevents full
extension or retraction
Operating the mast near overhead power lines
Operating the mast without the mast and operating space visible to the operator
Driving the vehicle with the mast in a deployed position (any height above the nested
position) or powered-up
Operating the mast or leaving deployed in wind speeds higher than the specified
maximum velocity
Operating the mast on a non-level surface greater than the specified maximum angle
Installing a payload greater than the maximum rated payload (weight and sail area) of
the mast
