Description & Introduction
The Master-Mite
®
is a versa-
tile, lightweight (only 28
ounces) heat gun that fea-
tures four heat ranges: 500°F,
650°F, 800°F, and 850°F. This
“whisper quiet” heat gun pro-
duces enough heat to apply
heat shrinkable tubing without
excessive air velocity so deli-
cate connectors or compo-
nents will not blow off the
work surface. While the
Master-Mite
®
is lightweight
and easy to hold for long peri-
ods of time, it also comes
standard with a bench stand
which adjusts to four heights
for hands-free operation. Six
attachments and accessories
are available for many varied
applications.
Master-Mite
®
ESD is safe to use.
It has a carbon fiber housing
which is fully grounded and
will not hold or create a static
charge like many plastics.
Housing surface conductivity
of 500 ohms/square. Conduc-
tive housing will not build up
or hold a static charge.
Each Master-Mite
®
heat gun
comes standard with a silver
650°F heating element, a
bench stand and one heat
shrink attachment for shrink
tubing. Should you require
additional elements and/or
attachments, please specify
separately.
Heat guns are a source of
extremely high temperature
flameless heat. As with
other products which gener-
ate extremely high tempera-
tures, regardless of your
specific application,
extreme care and caution
should be observed when
using this product.
Therefore, we recommend
that you pay particular
attention to the safety
instructions which we have
provided for your protection.

IMPORTANT
SAFETY INSTRUCTIONS
READ THESE INSTRUCTIONS
WARNING:
Hidden areas
such as behind walls, ceil-
ings, floors, soffit boards and
other panels may contain
flammable liquids that could
be ignited by the hot air gun
when working in these loca-
tions. The ignition of these
materials may not be readily
apparent and could result in
property damage and injury
to persons. Do not use if in
doubt about this hazard.
When working in these loca-
tions, keep the hot air gun
moving in a back-and-forth
motion. Lingering or pausing
in one spot could ignite the
panel or the material behind it.

Paint Stripping
WARNING:
Extreme care
should be taken when strip-
ping paint. The peelings,
residue and vapors of paint
may contain lead, which is
poisonous. Any pre-1977 paint
may contain lead and paint
applied to homes prior to 1950
is likely to contain lead. Once
deposited on surfaces, hand
to mouth contact can result in
the ingestion of lead. Exposure
to even low levels of lead can
cause irreversible brain and
nervous system damage;
young and unborn children
are particularly vulnerable.
Before beginning any paint
removal process you should
determine whether the paint
you are removing contains
lead. This can be done by
your local health department
or by a professional who used
a paint analyzer to check the
lead contact of the paint to be
removed.
LEAD-BASED
PAINT SHOULD ONLY BE
REMOVED BY A PROFES-
SIONAL AND SHOULD NOT
BE REMOVED USING A
HOT AIR GUN.
Persons removing paint
should follow these guidelines:
1. Move the work piece out-
doors. If this is not possi-
ble, keep the work area
well ventilated. Open the
windows and put an
exhaust fan in one of
them. Be sure the fan is
moving the air from inside
to outside.
2. Remove or cover any car-
pets, rugs, furniture, cloth-
ing, cooking utensils and
air ducts.
3. Place drop cloths in the
work area to catch any
paint chips or peelings.
Wear protective clothing
such as extra work shirts,
overalls and hats.
4. Work in one room at a
time. Furnishings should
be removed or placed in
the center of the room and
covered. Work areas
shoud be sealed off from
the rest of the dwelling by
sealing doorways with
drop cloths.
5. Children, pregnant or
potentially pregnant
women and nursing moth-
ers should not be present
in the work area until the
work is done and all
cleanup is complete.
6. Wear a dust respirator or a
dual filter (dust and fume)
respirator mask which has
been approved by the
Occupational Safety and
Health Administration
(OSHA), the National
Institute of Safety and
Health (NIOSH), or the
United States Bureau of
Mines. These masks and
replaceable filters are
readily available at major
hardware stores. Be sure
the mask fits. Beards and
facial hair may keep
masks from sealing prop-
erly. Change filters often.
DISPOSABLE PAPER
MASKS ARE NOT
ADEQUATE.
7. Use caution when operat-
ing the hot air gun. Keep
the hot air gun moving as
excessive heat will gener-
ate fumes which can be
inhaled by the operator.
8. Keep food and drink out
of the work area. Wash
hands, arms and face and
rinse mouth before eating
or drinking. Do not smoke
or chew gum or tobacco in
the work area.
9. Clean up all removed
paint and dust by wet
mopping the floors. Use a
wet cloth to clean all walls,
sills and any other surface
where paint or dust is
clinging. DO NOT SWEEP,
DRY DUST OR VACUUM.
Use a high phosphate
detergent or trisodium
phosphate (TSP) to wash
and mop areas.
10. At the end of each work
session put the paint chips
and debris in a double
plastic bag, close it with
tape or twist ties, and dis-
pose of properly.
11. Remove protective cloth-
ing and work shoes in the
work area to avoid carry-
ing dust into the rest of the
dwelling. Wash work
clothes separately. Wipe
shoes off with a wet rag
that is then washed with
the work clothes. Wash
hair and body thoroughly
with soap and water.

describing your problem and
your phone number.
Lubrication
The bearings are lubricated at
the factory and require no fur-
ther lubrication.
Cleaning
Unplug heat gun before clean-
ing. To clean outside of tool,
use only a mild soap and
damp cloth. Do not use other
cleaning agents, turpentine,
gasoline, lacquer or paint thin-
ner, or other solvents that may
contain chemicals which are
harmful to plastics and other
insulating materials. Never
immerse tool in a liquid or
allow a liquid to enter inside
the tool. Make sure all vents
and openings are free and
clear of debris.
Operating Instructions
Before performing an applica-
tion, we recommend that you
experiment with a piece of
scrap material. Use care in
approaching the work surface
until you find the proper dis-
tance from the work area and
the proper heat application
time.
Use a gentle back and forth
motion when applying heat
unless it is found that a con-
centrated heat is desired.
To Operate Heat Gun
1) Plug heat gun into properly
rated outlet.
2) Move slide switch to “Hot”
position. Heat gun will
come up to full operating
temperature in approxi-
mately two minutes.
5
3) When performing applica-
tions where hands-free use
is desired, use bench
stand.
4) To turn heat gun off after
use, move switch to “Cool”
position. Run on cool for
approximately three min-
utes. This will allow the
heat gun to cool down and
the nozzle and attachments
to become cool to the
touch.
5) Move switch to “Off”
position.
When heat gun is used in an
enclosed container, such as a
shrink tunnel or special enclo-
sure, ambient air must be
allowed to pass into the heat
gun and there must be an out-
let of equal size for the heated
air to pass out of the enclosure
also. Total enclosure will
cause damage or possible fail-
ure to the heat gun due to the
extreme heat generated.
NOTE: To prevent severe
damage to your heat gun,
DO NOT use high tem-
perature pinpoint attach-
ment #51074 with any
heating element other
than #20217.
