APPLICATIONS

WARNING To reduce the risk of heat

damage and personal injury, shield com-

bustible materials and areas adjacent to

workpiece. Protect yourself from hot paint

scrapings and dust.

Cutting Styrofoam

1. To attach the styrofoam cutting nozzle, ﬁ rst attach

reduction nozzle Cat. No. 49-80-0305 to the heat

gun (See “Installing Reduction Nozzles”). Attach

the styrofoam nozzle to the reduction nozzle.

2. To cut styrofoam, use a low to medium tem-

perature setting and apply heat to workpiece in

desired pattern. The nozzle will make straight or

curved cuts and will cut holes or recesses.

NOTE: Slight smoke and odors are normal and

are not harmful as long as you are working with

adequate ventilation. Cut at maximum

speed to avoid excess smoke development and

prevent the nozzle from overheating. Read the

safety instructions supplied with the

material you are cutting.

Soldering

Removing Paint

Read 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.

Creating Bends

Both variable temperature and dual temperature

heat guns are ideal for creating bends in plexiglass

that is used for guards and ﬁ xtures.

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.

MAINTENANCE

WARNING To reduce the risk of injury,

always unplug your tool before perform-

ing any maintenance. Never disassem-

ble the tool or try to do any rewiring on

the tool’s electrical system. Contact a

MILWAUKEE service facility for ALL repairs.

Maintaining Tools

Keep your tool in good repair by adopting a regular

maintenance program. Before use, examine the

general condition of your tool. Inspect guards,

switches, tool cord set and extension cord for

damage. Check for loose screws, misalignment,

binding of moving parts, improper mounting, bro-

ken parts and any other condition that may affect

its safe operation. If abnormal noise or vibration

occurs, turn the tool off immediately and have the

problem corrected before further use. Do not use a

damaged tool. Tag damaged tools “DO NOT USE”

until repaired (see “Repairs”).

WARNING To reduce the risk of injury,

electric shock and damage to the tool, never

immerse your tool in liquid or allow a liquid

to ﬂ ow inside the tool.

Cleaning

Clean dust and debris from vents. Keep the tool

handles clean, dry and free of oil or grease. Use

only mild soap and a damp cloth to clean your tool

since certain cleaning agents and solvents are

harmful to plastics and other insulated parts. Some

of these include: gasoline, turpentine, lacquer thin-

ner, paint thinner, chlorinated cleaning solvents,

ammonia and household detergents containing

ammonia. Never use ﬂ ammable or combustible

solvents around tools.

Repairs

If your tool is damaged, return the entire tool to the

nearest service center.

ACCESSORIES

For a complete listing of accessories refer to your

MILWAUKEE Electric Tool catalog or go on-line

to www.milwaukeetool.com. To obtain a catalog,

contact your local distributor or a service center.

WARNING To reduce the risk of injury,

always unplug the tool before attaching

or removing accessories. Use only speciﬁ -

cally recommended accessories. Others may

be hazardous.

1. Attach the soldering reﬂ ector nozzle or hook

nozzle to the heat gun.

2. Deburr 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

ﬂ ux. 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 ﬂ ux bubbles, add solder and position

heat gun so excess solder does not drip into the

heat gun.

Heat Shrinking

Fig. 2

Fig. 3

1. Attach the soldering reﬂ ector nozzle or hook

nozzle to the heat gun.

2. To heat shrink tubing, use a low temperature

setting. Apply heat to the workpiece using a side

to side motion until tubing has shrunk. Remove

heat immediately.

Cleaning Air Filters

Cat. No. 8986-20 and 8988-20 only

The air ﬁ lters on these heat guns may be removed

for cleaning.

1. Unplug tool.

2. To remove the air ﬁ lter, in-

sert a ﬂ at screwdriver be-

tween the motor housing

and air ﬁ lter and loosen

the air ﬁ lter off of the back

of the tool.

3. Slide the air ﬁ lter off the

back of the tool.

4. Remove the support pad from the air ﬁ lter using

the screwdriver.

5. Clean any dust or debris off the air ﬁ lter using

warm water and a brush.

NOTE: Allow the air ﬁ lter to dry before reinstall-

ing.

6. To reinstall the air ﬁ lter, slide the air ﬁ lter onto

the intake vent grooves from the back end of the

tool. Allow the air ﬁ lter to snap back into place.
