6.1 Work environment and safety

The hot air welder should be used only in the open or in a well-ventilated area.
Never use the hot air welder in explosive or readily infl ammable surroundings and maintain
su cient distance from combustible materials or explosive gases at all times!
Read the material safety data sheet of the manufacturer of the material and follow that compa-
ny's instructions. Be careful not to burn the material during the welding process.
Use the device only on a horizontal (roof slope up to 30°) and fi reproof support
In addition, comply with national statutory requirements regarding occupational safety (securing
safety of personnel or devices)!
Anti-fall protection when working on areas where there is a danger of falling.
When welding on roof parapet (parapet, eaves), the hot air welder on the carrying handle
(5) must be secured to a stop fi xture with horizontal guides (e.g. rail or rope safety sys-
tems) as protection against falling.
With respect to the safety chain, care must be taken to ensure that all of the safety elements
(carabiner hooks, ropes) have a minimum load-carrying capacity of 7 kN in every anticipatable
direction. For the suspension of the machine, it is mandatory to use clasp carabiners (Twist-Lock
or screw-types). All safety chain connections must be installed and checked correctly in accor-
dance with manufacturer's specifi cations.
