Changing Nozzles
The Model H8175 glue gun comes with three noz-
zles for different gluing applications and output
amounts. The all metal nozzle is for heavy duty
and high output applications. The long tip of the
silicon nozzle is ideal for bonding items with mini-
mal accessibility. The silicon coating reduces the
risk of accidental burns. After extensive use, the
nozzle may begin to drip excessively or produce
an intermittent flow. Nozzles should be changed
regularly to ensure an even flow and reduce the
risk of a possible fire hazard.
To change the glue gun nozzle:
1.
Heat the gun for approximately 1 minute to
soften the glue.
2.
Put on a pair of gloves, and use a wrench to
remove the nozzle.
3.
Flush the remaining glue through the gun to
clean the chamber.
Note: Never pull the glue stick out through
the back of the gun or it may damage the
feed mechanism.
4.
Thread the new nozzle onto the gun until
snug–do not overtighten.
Fluid Output Adjustment
The amount of glue being used can be preset by
using the fluid control knob, as shown in Figure
6. Lock the adjustment by screwing the adjust nut
towards the back of the fluid control knob until it is
flush with the gun body.
