OPERATION

To reduce the risk of injury, always
WARNING
wear safety goggles or glasses
with side shields. To reduce the risk of injury,
always unplug tool before attaching or removing
accessories or making adjustments. Use only
specifically recommended accessories. Others
may be hazardous.
Selecting Temperature
The proper amount of heat for each application
depends on the temperature selected, distance be-
tween the nozzle and workpiece, and the length of
time heat is applied. Experiment with scrap materials
and start with the lowest temperature. Be cautious
when working until the proper combination of heat,
distance and time of application has been obtained.

General Operation
1. To start the tool, grasp the handle
firmly and slide the switch to the
(2) position.
2. Allow the tool to heat up for ap-
proximately 3 minutes before
beginning work.
3. To adjust the temperature, use the
and buttons.
4. To adjust the air flow, press the
the air flow symbol
buttons.
5. Use a back and forth motion when applying heat
unless concentrated heat is desirable.
6. When done, slide the switch to the (1) position and
allow the nozzle to cool by placing the tool upright
on a flat surface using the support stand areas.
7. Place the cord so the heat gun won't tip.
8. Let the tool to cool down.
9. To stop the tool, slide the switch to the (0) position.
Hands-Free Use
The heat guns can be positioned upright on a stable
surface, leaving both hands free for the application.
Always place the tool upright on a flat surface using
the support stand areas. Place the cord so the heat
gun won't tip. The rear vent openings are designed
to allow air flow even when the tool is resting on the
end cap. Do not cover the vents with foreign materials
such as clothing or rags.

Read the Important Safety Instructions for Removing
Paint before proceeding with paint removal.
1. Begin work with low temperature setting.
2. Place nozzle approximately 1" away from work
surface.
3. Pass nozzle back and forth over a small area of
workpiece.
4. Gradually increase heat until paint starts to blister,
then remove heat.
5. Remove paint using a sharp-edged putty knife.
Both variable temperature and dual temperature heat
guns are ideal for creating bends in plexiglass that
is used for guards and fixtures.
1. To form a bend, use either a low or high tempera-
ture setting. When using a low temperature, hold
the heat gun close to the workpiece and pass the
nozzle back and forth slowly. When using a high
temperature, hold the heat gun further away from
the workpiece and pass the nozzle back and
forth rapidly.
2. Pass the nozzle over entire length of the surface to
be bent. Applying heat to only part of the surface
will make bending uneven.
1. Attach the air reduction or hook nozzle to the heat
gun.
and
2. De-burr the pipe and joint using sandpaper or steel
wool.
3. To solder with either lead or non-lead solder, coat
the tip on both the copper pipe and the joint with
flux. Then slip the joint over the pipe.
4. Slip the accessory nozzle around the joint. With
the heat gun at a high temperature setting, apply
heat to the joint.
5. When the flux bubbles, add solder and position
heat gun so excess solder does not drip into the
heat gun.
1. Attach the air reduction or hook nozzle to the heat
gun.
2. To heat shrink tubing, use a low temperature set-
ting. Apply heat to the workpiece using a side to
side motion until tubing has shrunk. Remove heat
immediately.
