GENERAL SAFETY RULES

WARNING!

READ AND UNDERSTAND ALL INSTRUCTIONS

Failure to follow all instructions listed below may result in

electric shock, fire, and/or serious injury.

SA VE THESE INSTRUCTIONS

WORK AREA

1. Keep your w ork area clean and well lit. Cluttered benches and dark areas invite

accidents.

2. Do not operate electric products in explosive atmospheres, such as in the

presence of flammable liquids, gases, or dust.

3. Keep bystanders, children, and visitors away while mounting or maintaining

the Air Filtration System.

ELECTRICAL SAFETY

4. Grounded products must be plugged into an outlet properly installed and

grounded in accordance with all codes and ordinances. Never remove the

SKU 91393 PAGE 2

grounding prong or modify the plug in an y way . Do not use any adapter plugs.

Check with a qualified electrician if you are in doubt as to whether the outlet

is properly gr ounded. If the product should electrically malfunction or break down,

grounding provides a low resistance path to carry electricity away from the user.

5. Double insulated products 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, re ver se 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.

6. Av oid body contact with grounded surfaces suc h as pipes, radiator s, ranges,

and refrigerators. There is an increased risk of electric shock if your body is

grounded.

7. Do not expose this product to rain or wet conditions. W ater entering an electric

product will increase the risk of electric shock.

8. Do not abuse the P ower Cord. N ever use the P ower Cord to carry the pr oduct

or pull the Plug from an outlet. Keep the Power Cord away from heat, oil,

sharp edges, or moving parts. Replace damaged Power Cords immediately.

Damaged Power Cords increase the risk of electric shock.

PERSONAL SAFETY

9. Stay alert. W atch what you are doing, and use common sense when operating

a power product. Do not use a power product while tired or under the influence

of drugs, alcohol, or medication.

10. Dress properly. Do not wear loose clothing or jewelry. Contain long hair.

Keep your hair, clothing, and gloves away from moving parts. Loose clothes,

jewelry, or long hair can be caught in moving parts.

11. Av oid accidental starting. Be sure the Po wer Switch is off before plugging in.

12. Use safety equipment. Always wear eye protection. During installation and

maintenance use non-skid safety shoes and ANSI approved safety goggles.

GROUNDING

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 power cord plug provided with

the product. Never remove the grounding prong from the plug. Do not use the

product if the power cord or plug is damaged. If damaged, have it repaired by

a service facility before use. If the plug will not fit the outlet, have a proper

outlet installed by a qualified electrician.

GROUNDED PRODUCT: PRODUCTS WITH THREE PRONG PLUGS

1. Products marked with “Grounding Required” have a three wire cord and three

prong grounding plug. The plug must be connected to a properly grounded

outlet. If the product should electrically malfunction or break down, grounding

provides a low resistance path to carry electricity away from the user, reducing

the risk of electric shock. (See Figure A.)

2. The grounding prong in the plug is connected through the green wire inside the

cord to the grounding system in the tool. The green wire in the cord must be the

only wire connected to the product’s grounding system and must never be

attached to an electrically “live” terminal. (See Figure A.)

3. Your product must be plugged into an appropriate outlet, properly installed and

grounded in accordance with all codes and ordinances. The plug and outlet

should look like those in the following illustration. (See Figure A.)

FIGURE A

SKU 91393 PAGE 5

DOUBLE INSULATED PRODUCTS: PRODUCTS WITH TWO PRONG PLUGS

4. Products marked “Doub le Insulated” do not require g rounding. They ha ve a special

double insulation system which satisfies OSHA requirements and complies with

the applicable standards of Underwriters Laboratories, Inc., the Canadian Stan-

dard Association, and the National Electrical Code. (See Figure B.)

5. Double insulated products may be used in either of the 120 volt outlets shown in

the following illustration. (See Figure B.)
