the glue gun to fully cool before storing it.
Glue sticks may remain in the glue gun when
it is not in use and be re-melted when the
glue gun is used again.
Operation
1. Connect the glue gun to the air regulator and
connect the air regulator to the air supply.
2. Plug the glue gun into a grounded outlet and
turn it ON with the power switch located at the
base of the glue gun.
Note: Never pull the glue stick out through
the back of the gun or it may damage the

Changing Nozzles
Temperature Adjustment
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.
The Model H8175 glue gun temperature can be
adjusted from 284°F–428°F.
To adjust the glue gun temperature:
1. using the screwdriver, adjust the tempera-
ture control located at the top of the glue gun
(Figure 7).
Temperature
Control
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.
Screwdriver
Storage
3. Flush the remaining glue through the gun to
clean the chamber.
Figure 7. Temperature control.
Note: Never pull the glue stick out through
the back of the gun or it may damage the
feed mechanism.
Note: The screwdriver can be stored in the
base of the glue gun for quick future use.
4. Thread the new nozzle onto the gun until
snug–do not overtighten.
NOTICE
Some materials are heat sensitive and may
become damaged either by the heated noz-
zle or the glue. Test the temperature setting
on a scrap piece of material.
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.
