5.2 Retooling for different welding widths
To retool to a dierent welding width, proceed in accordance with the sequence described below.
Allow the device to cool down in Cool Down mode.
Before beginning with dismantling work, make sure that the power cord (1) is disconnected from the
mains.
1. Release the cheese head screws M5 × 30 on the two drive/pressure rollers (7) (screw length varies depending
on roller type).
2. Remove the drive/pressure rollers (7).
3. Mount the new drive/pressure rollers (7).
4. Retighten the new M5 cheese head screws.
5. Release the hexagon socket screw.
6. Remove the welding nozzle (8) that is currently mounted.
7. Insert the desired welding nozzle (8).
8. Adjust the welding nozzle (8) (see Adjust welding nozzles 7 [5.1]).
9. Retighten the hexagon socket screw.
Step 1: Safety precautions
Step 2: Adjusting the roller width (analogous to the 15, 30, or 40 mm welding nozzle)
Step 3: Changing the welding nozzle (15, 30 or 40 mm)

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 sucient 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.
Step 1: Safety precautions

Check the basic setting of the welding nozzle (8).
• Check whether the material to be welded is clean between the overlap and on the upper and lower sides.
• Then check whether the welding nozzle (8), the drive/pressure roller (7), and the pressure belt (9) are
clean.
• If necessary, position the optionally available welding plate (see Scope of delivery 5 [4.2]).
Caution: The device may fall or drop in an uncontrolled manner due to gravity. The securing point is not designed
to withstand the shock-like stress of an abrupt fall.
Contact the manufacturer without hesitation if uncertainties arise during installation or operation.
Power cord and extension cable
• The nominal voltage specified on the device (see Technical data 3 [2]) must match the mains voltage.
• The power cord (1) must be able to move freely and must not hinder the user or third parties during work
(danger of tripping).
• The extension cable must be authorized for outdoor use and be marked accordingly. Take into account the
necessary minimum cross-section/gauge for extension cables, as required.
Generators for power supply
When using generators as a power supply, please ensure that the generators are grounded and equipped with
residual-current circuit breakers.
When selecting the nominal output of the generators, the formula «1.5 – 2 × nominal output of the semi-automa-
tic hot-air welder» applies.
