6.1 Work environment and safety
The semi-automatic hot-air welder must only be used in the open or in a well-ventilated area.
In addition, comply with national statutory requirements regarding occupational safety (securing
personnel or devices).
Use the device only on a fireproof surface.
Read the material safety data sheet of the manufacturer of the material and follow that company's
instructions. Be careful not to burn the material during the welding process.
Never use the semi-automatic hot-air welder in explosive or readily inflammable surroundings and
maintain sufficient distance from combustible materials or explosive gases at all times.
Anti-fall protection when working on areas where there is a danger of falling.
When welding on roof parapet (parapet, eaves), the semi-automatic hot-air welder must be
secured to an anchor point using the carrying handle (4) and a safety line (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
suspension of the machine, it is mandatory to use clasp carabiners (Twist-Lock or screw types). All sa-
fety chain connections must be installed and checked in accordance with manufacturer specifications.
Before each use and after any unusual occurrences, the
carrying handle (4)
that is used for fastening
the safety rope must be inspected by an individual with expertise in this area.
The
carrying handle (4)
is not permitted to exhibit any cracks, corrosion, notches or other material faults.
Caution
: Secure the semi-automatic hot air welder with the
carrying handle (4)
only!
Caution
: The semi-automatic hot-air welder must never be fastened to single anchoring points which
allow ropes to sag. The connection equipment must always be set to the shortest length possible in
order to eliminate the chance of falling over the edge of the parapet.
