  • 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.

IMPORTANT SAFETY INSTRUCTIONS FOR REMOVING PAINT

Warning WARNING
Use extreme care when stripping paint. Peelings, residue and vapors of paint may contain lead, which is POISONOUS.
Pre-1977 paint may contain lead and paint made before 1950 is likely to contain lead. Hand to mouth contact with paint peelings or residue from pre-1977 paint may result in lead ingestion. Exposure to even low levels of lead can cause irreversible brain and nervous system damage.
Young and unborn children are especially vulnerable to lead poisoning.
DO NOT REMOVE LEADBASED PAINT WITH A HEAT GUN.
Before beginning your work, determine whether the paint you are removing contains lead. A local health department or a professional who uses a paint analyzer can check the paint for lead content. LEADBASED PAINT SHOULD BE REMOVED ONLY BY A PROFESSIONAL.
Persons removing paint should follow these guidelines:

  • Work in a well ventilated area. If possible, move the workpiece outdoors. If working indoors, open windows and place an exhaust fan in a window. Be sure the fan is moving air from inside to outside. Proper ventilation will reduce the risk of inhaling chemicals found in the fumes or dust created by using a heat gun.
  • Remove or cover any carpets, rugs, furniture, clothing, cooking utensils and air ducts to prevent property damage from the paint peelings.
  • Place drop cloths in the work area to catch paint scrapings. Wear protective clothing such as hats, extra work shirts and overalls. Paint scrapings may contain chemicals that are hazardous.
  • Work in one room at a time. Remove furnishings or cover them and place in the center of the room.
    Seal doorways with drop cloths to seal work area from the rest of the building.
  • Children, pregnant or potentially pregnant women, and nursing mothers should not be near work area until all work is completed and work area is cleaned thoroughly.
  • 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 hair may keep masks from sealing properly. Change filters often. DISPOSABLE PAPER MASKS ARE NOT ADEQUATE.
  • Use caution when operating the heat gun. Keep the heat gun moving to prevent excessive temperatures.
  • Excessive heat can cause paint and other materials to burn and cause fumes, which may be inhaled by the operator.
  • Keep work environment clean. Keep food and drink away from work area. Wash hands, arms and face and rinse mouth before eating and drinking. Do not smoke, or chew gum or tobacco in the work area. Paint scrapings and dust created from removing paint may contain chemicals that are hazardous.
  • Clean up all paint scraping and dust. DO NOT SWEEP, DRY DUST OR VACUUM. Wet mop floors. Use a wet cloth to clean all walls, sills and other surfaces where paint and dust have accumulated. Use a high phosphate detergent, trisodium phosphate (TSP), or a trisodium phosphate substitute to clean and mop the work area.
  • Dispose of paint scrapings properly. Following each work session, place paint scrapings in a double plastic bag, close it with tape or twist ties and dispose.
  • Remove protective clothing and work shoes in the work area to avoid transferring dust to other parts of the building. 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

EXTENSION CORDS

Grounded tools require a three wire extension cord. Double insulated tools can use either a two or three wire extension cord. As the distance from the supply outlet increases, you must use a heavier gauge extension cord. Using extension cords with inadequately sized wire causes a serious drop in voltage, resulting in loss of power and possible tool damage. Refer to the table shown to determine the required minimum wire size.
The smaller the gauge number of the wire, the greater the capacity of the cord. For example, a 14 gauge cord can carry a higher current than a 16 gauge cord.
When using more than one extension cord to make up the total length, be sure each cord contains at least the minimum wire size required. If you are using one extension cord for more than one tool, add the nameplate amperes and use the sum to determine the required minimum wire size.
Guidelines for Using Extension Cords

  • If you are using an extension cord outdoors, be sure it is marked with the suffix “W-A” (“W” in Canada) to indicate that it is acceptable for outdoor use.
  • Be sure your extension cord is properly wired and in good electrical condition. Always replace a damaged extension cord or have it repaired by a qualified person before using it.
  • Protect your extension cords from sharp objects, excessive heat and damp or wet areas.

GROUNDING

Warning WARNING
Improperly connecting the grounding wire can result in the risk of electric shock. Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. Do not modify the plug provided with the tool. Never remove the grounding prong from the plug. Do not use the tool if the cord or plug is damaged. If damaged, have itrepaired by a MILWAUKEE service facility before use.
If the plug will not fit the outlet, have aproper outlet installed by a qualified electrician.

Grounded Tools (Three-Prong Plugs)
Tools marked “Grounding Required” have a three wire cord and three prong grounding plug. The plug must be connected to a properly grounded outlet(See Figure A). If the tool should electrically malfunction or break down, grounding provides a low resistance path to carry electricity away from theuser, reducing the risk of electric shock.
The grounding prong in the plug is connected throughthe green wire inside the cord to the groundingsystem in the tool.
The green wire in the cord must be the only wire connected to the tool’s grounding system and must never be attached to an electrically”live” terminal.
Your tool must be plugged into an appropriate outlet, properly installed andgrounded in accordance with all codesand ordinances. The plug and outlet should look like those in Figure A.milwaukee 8988-20 Variable Temperature Heat Gun with LCD - GROUNDINGDouble Insulated Tools (Two-Prong Plugs)
Tools marked “Double Insulated” do not requiregrounding. They have a special double insulationsystem which satisfies OSHA requirements andcomplies with the applicable standards of Underwriters Laboratories, Inc., the Canadian Standard Association and the National Electrical Code. Double Insulated tools may be used in either of the 120 volt outlets shown in Figures B and C.milwaukee 8988-20 Variable Temperature Heat Gun with LCD - GROUNDING 2
