DANGER!
Danger of falling!
Careless working on the roof can lead to falls.
When working on a roof you must wear appropriate safety equipment. Never
use the tool backwards, but always in a forwards direction (see sections on
Hazards and Work position).
The induction welding tool and the magnets may have an effect on the
function of cardiac pacemakers and implanted defibrillators. It is possible
that cardiac pacemakers switch to test mode and cause discomfort. It is
possible that defibrillators cease to function. If you are fitted with any such
instruments, you must keep a minimum distance of 50 cm from the inductor
(also hand inductor) and the magnets. You must warn persons fitted with such
instruments against coming too close to the magnets and inductors.
Before installing the waterproof membrane, SFS recommends that the posi-
tion of the plates on top of the insulation be checked. Should the height of
any stress plate be incorrect, the height needs to be corrected.

Before carring out the welding, SFS recommends marking the position of the
stress plates on the top face of the waterproof membrane.
1. Preparing the magnet.
2. Place inductor (1) on stress plate.
3. Press the start button on the handle (3).
a. If the unit has been placed correctly, which means that the cover is sufficient,
a continuous signal sound will be heard (1 second) and the status display
changes to orange. The welding process will start automatically.
b. If the unit is not correctly placed, i.e. the cover is insufficient, the inductor (1) has
to be moved until the position is correct (see Fig.1). As soon as the position is
correct, the welding process starts automatically.
c. The tool is equipped with an acoustic search mode which helps the user to posi-
tion the inductor precisely on the stress plate. The search mode is active for
max. 15 seconds. When the time limit has been exceeded, a failure signal sound
can be heard (2 seconds). In this case, acknowledge the
signal by pressing the
cool down and restart the welding process (step 1 and
subsequent steps).
