Each time the trigger (item 7) has been pulled, the
applicator must audibly vent through the vent valve
("SEV"). If the sound absorber (item 8) got stuck, the
glue tank may be under pressure.
Cleaning the Vent Valve
Warning:
With this, hot glue might come out of the
sound absorber!
If the vent valve is clogged, hotmelt can
exit the glue gun through the nozzle even
when the device is switched off!
Prevent liquid glue from getting into the sound absorber,
when the applicator is ready for operation by …
● depositing the glue applicator on a level plane, using
its wire bracket;
● depositing the glue applicator on the stand (# 2770,
included in TR 60 / TR 80 );
● suspending the glue applicator at a spring balancer
(# 3544);
● filling the glue applicator only up to approx. 1.5 cm
below the upper rim;
● always pointing the nozzle downwards.
If nevertheless glue got into the vent valve, replace it or
clean it if possible and when the glue gun is warmed up.
Replacement or cleaning of the vent valve when the glue
gun is cold may lead to damaging the device.
