Operation - Milwaukee 8975 Operator's Manual

To reduce the risk of injury, wear safety goggles or
glasses with side shields.
Using the Temperature Control Switch (Fig. 1-3)
Cat. No. 8975 Dual Temperature Control Heat Guns are provided with a 3
position rocker switch. Place the switch in the center position for "Low"
range or press in the lower position of the switch completely for "High"
range. The markings on the switch correspond to these positions:
O = Off
I = Low Temperature
I I = High Temperature 1000° F (540° C)
Fig. 1
Cat. No. 8977 variable temperature model heat gun is marked "O" for OFF
and "l" for ON. Temperature is controlled by turning the end cap in the
directions dictated by the arrows.
Fig. 2
Cat. No. 8978 features an electronic temperature control system, which
allows the tool to produce a greater concentration of heat at the nozzle,
allowing the use of various accessory nozzles.

OPERATION

The electronic control system regulates the temperature within the tool's
heating element. Unlike non-electronic heat guns, MILWAUKEE's elec-
tronic heat gun will maintain the same temperature even when the air
flow is decreased or restricted with the use of accessory nozzles.
Cat. No. 8978 is a variable temperature heat gun with a range between
212° F and 1100° F (100° C to 593° C). The heat adjustment knob is a dial
with numbers 1 through 6 on it as shown. The lower numbers corre-
spond to cooler temperatures and higher numbers correspond to warmer
temperatures. To adjust temperature, simply turn the dial to the left or the
right.
Using the Temperature Control Switch
The electronic temperature control system regulates the temperature
within the tool's heating element. Unlike non-electronic heat guns,
MILWAUKEE's electronic heat gun will maintain the same temperature
even when the air flow is decreased or restricted with the use of
accessory nozzles. Refer to the airflow/temperature chart for various
airflow and temperature settings.
Selecting Temperature
The proper amount of heat for each application depends on the
temperature range selected, distance between the nozzle and workpiece,
and the length of time heat is applied. Experiment with scrap materials
and start with lowest temperature range. Be cautious when working until
the proper combination of heat, distance and time of application has been
obtained. Use a back and forth motion when applying heat unless
concentrated heat is desirable.
Support Stand
Cat. Nos. 8975, and 8977 feature a support stand, which allows you to
position the heat gun upright on a workbench, leaving both hands free
for your application. When using Cat. Nos. 8975 and 8977 on a work-
bench, always place tool on a flat surface and snap the support stand
into the notched position. 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, but it is important not to cover the vents with
foreign materials such as clothing or rags. Cat. No. 8978 has a flat
bottom surface that acts as a support stand. Rest the tool on the flat
surface, making sure to place the cord so the heat gun won't tip.
Cleaning Air Filters (Fig. 4)
The air filters on these heat guns may be removed for cleaning.
1. Unplug tool.
2. To remove the air filter, insert a flat screwdriver between the motor
housing and air filter and loosen the air filter off of the back of the
tool (Fig. 4).
3. Slide the air filter off the back of the tool.
4. Remove the support pad from the air filter using the screwdriver.
5. Clean any dust or debris off the air filter using warm water and a
brush. NOTE: Allow the air filter to dry before reinstalling.
6. To reinstall the air filter, slide the air filter onto the intake vent grooves
from the back end of the tool. Allow the air filter to snap back into
place.
