Safety precautions
Before starting work, check that the hot-air blower (4) has been switched off at the air blower switch (9)
and the drive switch (16) have been switched off . The hot-air blower (4) must be in the parking position.

6.1 Working environment and safety

The automatic hot-air welding machine should only be used in the open or in a well-ventilated area.
Never use the automatic hot-air welding machine in a potentially explosive or highly fl ammable atmo-
sphere and always keep your distance from fl ammable materials or explosive gases.
Read the material safety data sheet provided by the material manufacturer and follow the instructions
it contains. Be careful not to burn the material during welding.
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 locking hook must be secured to a stop fi xture
with horizontal guides (e.g. rail or rope safety systems) 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 sus-
pension 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 accordance with manufacturer's specifi cations.
Before each use and after unusual occurrences, the locking hook that is used for fastening the safety
rope must be inspected by an individual with expertise in this area. The locking hook is not permitted
to exhibit any cracks, corrosion, notches or other material faults.
