Heat guns are a source of
extremely high temperature
flameless heat (up to
1050°F/566°C). As with other
products which generate
extremely high
temperatures, 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.

Read These Instructions.
WARNING: Extreme care
should be taken when stripping
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 uses a paint
analyzer to check the lead
content of the paint to be
removed.
LEAD BASED PAINT
SHOULD ONLYBE
REMOVED BY A
PROFESSIONAL AND
SHOULD NOT BE REMOVED
USING A HEAT GUN.
Hidden areas such as behind
walls, ceilings, floors, soffit
boards and other panels may
contain flammable materials
that could be ignited by the heat
gun when working in these
locations. The ignition of these
materials may not be readily
apparent and could result in
property damage and injury to
persons.
When working in these
locations, keep the heat gun
moving in a back-and-forth
motion. Lingering or pausing in
one spot could ignite the panel
or the material behind it.
Persons removing paint should
follow these guidelines:
1. Move the work piece
outdoors. If this is not
possible, 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
carpets, rugs, furniture,
clothing, 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 should
be sealed off from the rest of
the dwelling by sealing
doorways with drop cloths.
5. Children, pregnant or
potentially pregnant women
and nursing mothers should
not be present in the work
area until the work is done
and all clean up is complete.
6. Wear a dust respirator mask
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
3
Important Safety Instructions
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
properly.
PAPER MASKS
ARE NOT ADEQUATE.
7. Use caution when operating
the heat gun. Keep the heat
gun moving, as excessive
heat will generate 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
dispose of properly.
11. Remove protective clothing
and work shoes in the work
area to avoid carrying 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.
12. WARNING: To reduce the
risk of fire or electric shock,
do not expose heat guns to
rain or moisture. Store
indoors. Connect to
grounded outlet only.
13. Do not use plug adapters or
remove the ground prong
from the plug. This tool is
equipped with a 3-prong
plug and a 3-wire grounding
system. Connect to properly
grounded outlets only.
14. Use heat gun only on
adequately rated circuits to
avoid overheating of
electrical systems.
15. Proheat heat guns can
produce up to 1050°F of
flameless heat out of the
nozzle. Do not direct this hot
air stream at your clothing,
hands or body parts. Do not
use as a hair dryer.
16. Do not touch nozzle
opening or nozzle shield
until cool. When in “Hot”
mode, extreme heat is
generated at those areas.
Always hold tool by the
handle or use permanently
attached stand.
17. Run on cool before turning
off. The nozzle and shield
require approximately 3
minutes to become cool to
the touch. Stand the unit on
its end with the nozzle
pointing upward after turning
off.
18. Do not touch work surface
with nozzle. Scrape paint

areas invite accidents or
injury.
20. Keep away from children. All
visitors should be kept at a
safe distance from the work
area. Do not let visitors
touch the tool or extension
cord.
21. Use tool in a well-ventilated
area. Do not use near
flammable liquids or in an
explosive environment
(where fumes, gases or dust
are present).
22. Remove all highly flammable
materials and other debris
from the work area.
23. Wear safety glasses at all
times.
24. When using an extension
cord, use only a 3-wire
grounded cord with a
minimum of 14-gauge
capacity. We recommend
they be listed by Underwriters Laboratories (UL) in
the U.S.A. or (CSA)
Canadian Standards
Association in Canada and

The proper amount of heat for
each application is dependent
on three variables:
1. The volume/speed of
airflow along with distance
of nozzle from work
surface.
2. Length of time that heat
is applied and airflow.
3. Combination of air and
settings. Experiment with
these variables to better
learn the capabilities of
this heat gun.
Before performing any
application, we recommend
that you experiment with a
piece of scrap material. Use
care in approaching the work
until you
find the proper
combination of heat and air
velocity control, distance and
the heat application time.
4) Move switch to zero(O)"Off"

exhaust mode), and
keeping a clean work area.
When dust or vapors are
present, use a respirator
designed to filter lead.
Move work outside when
possible.
Failure to follow adequate
safety precautions when
working with lead based
paint could result in lead
poisoning. See our Paint
Stripping instructions for
more information.
3) Keep away from chemical
paint strippers which can
ignite or release harmful
vapors.
4) Use adequate ventilation
(such as a window fan in
exhaust mode) and keep
your work area clean.
5) Wear gloves and safety
glasses at all times.
6) Keep a fully charged fire
extinguisher close at hand.
7) Stay alert, watch what you
are doing, and use
common sense.
Stripping Paint
1) To strip paint, turn unit on
and hold it about 1 inch
from the surface being
stripped. Proper distance
and speed of stripping
should be determined by
experience. It is an
advantage to hold the gun
further from the surface and
to move forward slowly.
Slower speed is
compensated by the wider
1)
WARNING: With a heat
gun, as with all other heat
tools, keep a fire
extinguisher handy and
observe all sensible fire
precautions.
We do not recommend
using this heat gun on
hollow surfaces such as
outdoor siding, walls,
soffits, panels and
partitions, etc. These areas
often contain flammable
materials such as dust,
wood chips, insulation,
rodent nests and other
debris which could
accidentally ignite.
Your heat gun is best used
for stripping paint from solid
woodwork with ins and
outs, such as solid interior
trim, mouldings, turnings,
doors balusters and porch
trim, etc.
When stripping paint,
always keep the heat gun
moving in a continuous
back and forth motion.
Stopping or pausing too
long in one spot could ignite
the surface you are working
on or the area behind it.
2) Do not breathe or swallow
lead based paint in any
form. Many old homes and
other buildings contain lead
based paint. Dust,
scrapings, residues and
vapors of lead based paint
are extremely poisonous.
Prevent possible lead
poisoning when stripping
this type of paint by using
adequate ventilation (such
as a window fan in the
softened areas. Heat will
also penetrate deeper.
2) As paint begins to blister
and bubble, move gun
slowly in a steady
progression across the
surface. Follow closely with
a scraping knife (a 2-inchwall scraper works best) to
scrape the loosened paint.
Preheat scraper as you are
heating the paint surface.
This increases the speed of
paint stripping.
a. Removal of paint by
using heat is based on
the fact that all organic
paints soften at elevated
temperatures. When soft,
the paint can be easily
lifted off without damage
to the surface.
b. When stripping paint
from grooves in
mouldings, you can
devise your own scraping
tools. Old screwdrivers
with ground-down blades
and linoleum knives are
often used.
3) Move switch to "Low" after
use. Run for three minutes
and turn to “Off”.
