GUNDLACH
HEAT GUNS
Limited Warranty on Heat Guns
Our Heat Guns are guaranteed for six months against defects in workmanship
and materials from the time of shipment from our factory. This warranty does
not cover the heating element.
In-warranty replacements due to defective material or workmanship (not
misuse or abuse) will be made on a no charge basis. No replacement charges
will be accepted without our authorization.
Our warranty will not apply if the Heat Gun has been tampered with, or where
repairs or attempted repairs have been made by persons other than our em-
ployees, repairs due to normal wear, abuse in using the Heat Gun, accident,
damage in transit, or if misuse is evident.
Each Heat Gun is inspected and tested before leaving our factory. Should a
new Heat Gun fail to operate after it is unpacked from the carton, return the
complete unit to our factory, or to our distributor, immediately.
Beno J. Gundlach Co. will not assume any responsibility for damage or ac-
cidents resulting from the use of our Heat Guns, due to misapplication or
nonadherence to safety and precautionary measures.
4 Points to Check Before Using!
Voltage
Be sure the line voltage is the same as that shown on the heat gun, before plugging
into the circuit.
Ground Wire
The heat gun is equipped with a 3 prong plug; it should be plugged into a 3-hole
electrical receptacle that is properly grounded.
To Prevent Shock or Serious Injury
Never operate while the user is standing in water or on a wet surface.
Keep Out of Reach of Children!

Safety
Warning:
Hidden areas such as behind walls, ceilings, floors, soffitboards and other panels may contain flammable
materials that could be ignited by the heat gun when working in these locations. The ignition of those ma-
terials 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.
Warning: Important Safety Instructions
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 l950 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 remov-
ing 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 only be
removed by a professional and should not be removed using a heat gun.
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 States Bureau of Mines. These masks and replaceable
filters are readily available at major hardware stores. Be sure the mask fits. Beards and facial hairs
may keep masks from sealing properly. Change filters often. Disposable paper masks are not
adequate.
7. Use caution when operating the heat gun. Keep the heat 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 eat-
ing 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.
Save these instructions.

Notes:

Operating Tips
To start: Move switch to the HOT position, which starts motor and heat unit.
Important: Be sure at all times that the motor is running when the heat
is on.
After using the Heat-Blo Gun, flip the switch to the COLD blowing posi-
tion and allow to operate for several minutes to cool the element and help
preserve and extend its life; then, turn the switch to the OFF position. Do
not stop the flow of heated air by holding the tip too close to a surface, as
this will cause overheating and damage to the heating element.
The shield supplied with each heat gun is for the operators protection.
Be sure that the shield covering the nozzle of the heat gun is cool before
storing or placing on or near flammable materials. Also, be sure that the
shield that fits over the nozzle of the heat gun is securely attached at all
times. If repairs are needed we recommend that the unit be returned to
the factory.
To avoid fumes or explosion: Never use the heat gun in an atmo-
sphere where explosive gases or combustible gases exist. Do not direct
the nozzle of the gun directly towards a combustible substance or mate-
rial. Always place the heat gun upon its stand when setting it down.
CAUTION: When the heat gun is on or in use, do not touch the nozzle
with your bare hands or any part of your body!
Extension cord: If it is necessary to use an extension cord with the heat
gun, it should be at least 14 gauge wire size to avoid a serious drop in
voltage, loss of power, or possible damage because of overheated wires.
Temperatures: The temperature varies at the nozzle depending upon
the distance between the nozzle tip and the part being heated. The gun
nozzle should not be held closer than ½” from the part being heat-
ed. Temperature is controlled by adjusting the amount of air taken in at
the air intake cover. Maximum heat is reached when the louvers are fully
closed. Minimum heat is attained when the louvers are fully opened. To
adjust heat, turn knob on the air intake cover and open or close louvers
as desired.
