4.2 Charging
Burn hazard!
Nozzle and molten adhesive can be over 392 °F / 200 °C hot. Always wear heat-resistant
gloves when performing the steps described below.
1. Place the device in the working bracket or on the base.
2. Switch the device on (see Section 3.2). Wait until the working temperature has been
reached.
3. Take hold of the device by the handle with one hand (17). With the other hand turn the
lever (10) clockwise through 180º and swivel the closure cap open.
4. Fill the tank to a level not less than 2 cm below the rim. The maximum level is marked
on the device with a sticker (see illustration left). Do not charge the device above this
level since the melt expands when heated.
5. Swivel the closure cap back. Turn the lever (10) anticlockwise as far as it will go, in
order to lock the cap.
4.3 Discharging and metering melt
1. Place the device in the working bracket or on the base.
2. Switch the device on. Wait until working temperature has been reached.
3. Check that there is enough melt in the tank.

If the device is “run dry” drops of melt may escape uncontrolled and endanger the opera-
tor and persons in the vicinity.
Every time you actuate the trigger, therefore, first carry out step (3.) above.
4. Actuate the trigger (16)
You can meter the quantity discharged by altering the pressure (max. 87 psi / 6 bar) at
the pressure regulator (3) and/or selecting an appropriate nozzle.

tely and the tank vented.
