Charging melt adhesive

Attention: Burn hazard!
Nozzle, molten adhesive and the areas marked with warning labels can be over 200 °C
hot. Always wear heat-resistant gloves when performing the steps described below.
Only touch these areas with insulated thermal gloves.
The adhesive can be re lled as soon as the ll level has dropped below the reserve in the
tank or below the marking on the outside of the housing.
1. Place the device in the working bracket or on the base.
2. Switch the device on (see section 3.3 on page 22). Wait until the working temperature
has been reached.
3. Take hold of the device by the handle with one hand (14). With the other hand turn the
lever (9) clockwise through 180° and swivel the closure cap open.
4. Fill the tank up to a maximum of 2 cm below the edge. The maximum level is marked
on the device with a sticker (see illustration left). Do not fill up the device beyond that
point as the hot melt material will expand when heated.
5. Swivel the closure back. Press the handle (9) sturdily and turn it 180° counter-clock-
max. Level
