Safety Instructions

for Heating Appliances

Work Area

• Keep your work area clean and well lit.

Cluttered and dark areas invite accidents.

• Do not operate heating appliance in explosive atmospheres, such as in the presence of flammable liquids, gases or dust, dry grass, leaves and paper. Heating appliances generate

high temperatures which may ignite the dust or fumes. Combustible materials like dry grass,

leaves and paper will scorch and may catch fire.

• Keep bystanders, children and visitors away while operating a heating appliance.

Distractions can cause you to lose control.

Electrical Safety

• Before plugging in the heating appliance, be certain the outlet voltage supplied is compatible with the voltage marked on the nameplate within 10%. An outlet voltage incompat-

ible with that specified on the nameplate can result in serious hazards and damage to the heating appliance.

• Double Insulated heating appliances are equipped with a polarized plug (one blade is wider than the other.) This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install a polarized outlet. Do not change the plug in any way. Double

Insulation eliminates the need for the three wire grounded power cord and grounded power supply system. Polarized plug inserted in properly wired outlet insures that no voltage is supplied to the tool when switch is “OFF”.

• When operating a heating appliance use Ground Fault Circuit Interrupter (GFCI) on the circuit or outlet. Don’t expose heating

BM 2610910610 9/01 10/4/01, 10:12 AM3

appliance to rain or wet conditions. Water entering a heating appliance will create an electric shock hazard.

• Do not abuse the cord. Never use the cord to carry the heating appliance or pull the plug from an outlet. Keep cord away from heat, oil, sharp edges or moving parts. Replace damaged cords immediately. Damaged

cords create electric shock hazard.

• When operating a heating appliance with an extension cord while outdoors, use only extension cords marked W–A or W. These

cords are rated for outdoor use and reduce the risk of electric shock.

Personal Safety

• Stay alert, watch what you are doing and use COMMON SENSE when operating a heating appliance. A moment of inattention or

use of drugs, alcohol or medication while operating a heating appliance can be dangerous.

• Use safety equipment. Always wear safety goggles. Dust mask, protective gloves, safety

shoes or non-skid shoes, must be used for appropriate conditions.

• Avoid accidental starting. Be sure switch is “OFF” before plugging in. Carrying the

heating appliance with your finger on the switch or plugging in the heating appliance that has switch “ON” invites accidents.

• Do not direct hot tip or nozzle toward clothing, hands or other body parts. Intense heat from tip or nozzle can cause serious burns or cause clothing to ignite.

• Do not touch nozzle or shield until completely cool. During use very high tempera-

tures are generated in these areas.

• Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, body, clothing and gloves away from nozzle or shield. Clothing or hair could ignite from extreme heat.

• Do not overreach, keep proper footing and balance at all times. Proper footing and

balance enables better control of the heating appliance in unexpected situations.

Tool Use and Care

• Do not use heating appliance if switch does not turn it “ON” or “OFF”. Any tool which

cannot be controlled by the switch is dangerous.

• Disconnect the plug from the power source

before making any adjustments or changing accessories. Such preventative safety measures

reduce the risk of starting the heating appliance accidentally.

• Store idle heating appliance only after adequate cooling period, indoors in high, dry place out of the reach of children and untrained persons. Heating appliances are dan-

gerous in the hands of untrained persons.

• Do not leave heating appliance unattended while it is running or cooling down. Always

set tool on a flat, level surface so that nozzle tip is directed upwards, away from supporting surface while running or cooling down.

• Keep a fully charged fire extinguisher close at hand for emergency use.

Service

• Heating appliance service must be performed only by qualified repair personnel.

Service or maintenance performed by unqualified personnel may result in misplacing internal wiring and components which could cause serious hazard.

Specific Safety Rules for

Heat Guns

Paint Stripping Safety Instructions

PERSONS REMOVING PAINT SHOULD FOLLOW THESE GUIDELINES:

WARNING! This heat gun generates extremely high temperatures (as high as 1100

°F). 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. Keep the heat gun moving in a back and forth motion, do not linger or pause in one spot as the panel or material behind it may ignite. The ignition of

these materials may not be readily apparent and could result in property damage and injury to persons.

• Use caution when operating the heat gun.

Excessive heat will generate fumes which inhaled may be dangerous to the operator.

WARNING! Use extreme care when stripping paint. The peelings, residue and vapors of

BM 2610910610 9/01 10/4/01, 10:12 AM4

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 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.

• Move the workpiece 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.

• Seal work areas from rest of dwelling by sealing openings or doors with drop cloths.

Work in limited areas or one room at a time will help to limit paint or dust contamination.

• Remove or place furnishings in center of room then cover any carpets, rugs, furniture, clothing, cooking utensils and air ducts.

Place drop cloths in the work area to catch paint chips or peelings, 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.

• Do not allow children, pregnant or potentially pregnant women and nursing mothers in work area until work and clean up is complete. Certain individuals may be at risk, if

not properly protected.

• Do not eat or keep food and drink in work area. Do not smoke or chew gum or tobacco products in the work area. Paint residue or

dust may settle on or in food containers which can cause the transmission of poisons to your body.

• Wear a dust respirator mask or dual filter (dust and fume) respirator mask which has

been approved by the Occupational Health and Safety Administration (OSHA), the National Institute of Safety and Health (NIOSH) or the United States Bureau of Mines. These

types of masks and replaceable filters are readily available at major hardware stores. Be sure the mask fits securely, beards and facial hair may keep masks from sealing properly. Change filters often. DISPOSABLE PAPER MASKS

ARE NOT ADEQUATE.

• Wear protective clothing such as extra work shirts, overalls and hats. Paint residue

or dust may settle on your skin which may cause the transmission of poisons to your body.

• DO NOT SWEEP, DRY DUST OR VACUUM paint shavings, dust or peelings during the clean up process. 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. Use a phosphate detergent or trisodium phosphate (TSP) to wash and mop areas.

• Always remove protective clothing and work shoes in the work area to avoid carrying dust into 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 including hands, arms and face thoroughly with soap and water. Rinse your mouth

Some dust created by

power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

• Lead from lead-based paints,

• Crystalline silica from bricks and cement and other masonry products, and

• Arsenic and chromium from chemically treated lumber.

Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.

Operating the Tool

• Double Insulation is a design concept used in electric power tools which eliminates the need for the three wire grounded power cord and grounded power supply system. It is a recognized and approved system by Underwriter’s Laboratories, CSA and Federal OSHA authorities.

IMPORTANT: Servicing of a tool with

double insulation requires care and knowledge of the system and should be performed only by a qualified service technician. WHEN SER-

Air flow setting:

The air flow is set steplessly with air flow blower speed dial 3. A lower air stage may be required in certain cases, e.g. to avoid overheating the workpiece's surroundings or to avoid displacing the workpiece if the air flow is too strong. A higher air stage heats up the workpiece more quickly and enables the hot air gun to be held at a greater distance from the workpiece.

VICE IS REQUIRED USE ONLY IDENTICAL REPLACEMENT PARTS.

POLARIZED PLUGS: If your tool is equipped with a polarized plug (one blade is wider than the other), this plug will fit in a polarized outlet

only one way. If the plug does not fit fully in the

outlet, reverse the plug. If it still does not fit,

(Hot air stage) 17.8 CFM ª1100ºF. contact a qualified electrician to install the proper outlet. To reduce the risk of electric shock do not change the plug in any way.

Temperature control (thermo-electronic): The temperature can be controlled steplessly

with the setting dial 5 and switch 6 in setting II.

Thermo-electronic

Extension Cords

• Replace damaged cords immediately. Use of damaged cords can shock, burn or electrocute.

• If an extension cord is necessary, a cord with adequate size conductors should be used to prevent excessive voltage drop, loss of power or overheating. The table below shows the correct size to use, depending on cord length and amperage rating on the tool’s nameplate. If in doubt, use the next heavier gauge. Always use U.L. and CSA listed extension cords.

"SAVE THESE INSTRUCTIONS"

If the nozzle is hot or if you wish to have both hands free when working, you can set the tool down in an upright position on its base.

Temperature displays:

The temperature is displayed via LED 4. By carefully controlling the air flow and temperature, very precise work can be performed on temperature sensitive electrical fittings, packaging, and other materials.

The ideal temperature should first be ascertained by performing a test. You should therefore start with a low temperature setting. The temperatures specified in the illustrated examples of use are recommended values which can vary depending on the properties of the workpiece. The distance between the nozzle and workpiece is dependent on the material to be processed. Additional information can be found in popular DIY books or consult the manufacturer of the heat activated product.

NOTE: The 1100ºF(595ºC) setting can not be reached on full air flow setting. If 1100ºF(595ºC) is required, reduce setting on blower speed dial 3 until 1100ºF(595ºC) is indicated on LED temperature display 4.

Bosch stocks a range of accessories (see catalog) which offer a wide range of other applications.

The sections indicated by capital letters in the instructions for use below refer to the illustrated examples of use in this manual.

Removing paint/dissolving adhesives Fit the flat nozzle. Soften the paint using hot air

and remove evenly using a scraper. Do not heat the paint for too long since this will burn the paint, making it more difficult to remove. To carry out work in confined spaces, remove the heat shield. Many adhesives (e.g. stickers) become softer when heated, allowing adhesive bonds to be separated and adhesive to be removed.

Defrosting water pipes

Fit the reflector nozzle. Always heat the frozen area inwards from the edge to the center.

CAUTION! Do not attempt to defrost PVC piping.

Note: Water pipes are often difficult to distinguish from gas pipes. Copper pipes are joined using tin and should therefore not be heated above 392ºF (200ºC).

Removing paint or caulking from

windows

Glass can break easily. Always use the glass deflector nozzle. On profiled surfaces, paint can be removed using a scraper and brushed off using a soft wire brush.

Shrink fitting electrical connections

Fit the reflector or reducing nozzle. Select a heat-shrinkable sleeve with a diameter matching that of the workpiece, e.g. cable lug. Heat the heat-shrinkable sleeve evenly.

Maintenance and Service

WARNING! Preventive maintenance per-

formed by unauthorized personnel may result in misplacing of internal wires and components which could cause serious hazard. We recommend that all tool service be performed at a Bosch Factory Service Center.

Tool Lubrication

Your Bosch tool has been properly lubricated and is ready for use. We recommend, that tools with gears be regreased with a special gear lubricant every time the brushes are changed.

Carbon Brushes

The brushes and commutator in your Bosch tool have been engineered for many hours of dependable service. To maintain peak efficiency of the motor, we recommend that every two to six months the brushes be examined. Only genuine Bosch replacement brushes specially designed for your tool should be used.

Bearings

After about 300-400 hours of operation, or at every second brush change, the bearings should

be replaced at a Bosch Factory Service Center. Bearings which become noisy (due to heavy load or very abrasive material cutting) should be replaced at once to avoid overheating and motor failure.

Cleaning

WARNING! To avoid accidents, always

disconnect the tool from the power supply before cleaning or performing any maintenance. The tool may be cleaned most effectively with compressed air. Always wear safety goggles when cleaning tools with compressed air.

Ventilation openings and switch levers must be kept clean and free of foreign matter. Do not attempt to clean by inserting pointed objects through openings.

CAUTION! Certain cleaning agents and

solvents damage plastic parts. Some of these are: gasoline, carbon tetrachloride, chlorinated cleaning solvents, ammonia and household detergents that contain ammonia.
