TABLE A

USE PROPER EXTENSION CORD.9. Make sure your extension cord is

in good condition. When using an

extension cord, be sure to use one

heavy enough to carry the current

your product will draw. An undersized

cord will cause a drop in line voltage

resulting in loss of power and over-

heating. Table A shows the correct

size to use depending on cord length

and nameplate ampere rating. If in

doubt, use the next heavier gauge.

The smaller the gauge number, the

heavier the cord.

WEAR PROPER APPAREL. Do not10. wear loose clothing, gloves, neck-

ties, rings, bracelets, or other jewelry

which may get caught in moving

parts. Nonslip footwear is recom-

mended. Wear protective hair cover-

ing to contain long hair.

ALWAYS USE SAFETY GLASSES.11. Also use face or dust mask if cutting

operation is dusty. Everyday eye-

glasses only have impact resistant

lenses, they are NOT safety glasses.

SECURE WORK. Use clamps or a12. vise to hold work when practical. It’s

safer than using your hand and it

frees both hands to operate tool.

DON’T OVERREACH. Keep proper13. footing and balance at all times.

MAINTAIN TOOLS WITH CARE.14. Keep tools sharp and clean for best

and safest performance. Follow

instructions for lubricating and chang-

ing accessories.

DISCONNECT TOOLS before ser-15. vicing; when changing accessories,

such as blades, bits, cutters, and the

like.

REDUCE THE RISK OF UNINTEN-16. TIONAL STARTING. Make sure

switch is in off position before plug-

ging in.

USE RECOMMENDED ACCESSO-17. RIES. Consult the owner’s manual for

recommended accessories. The use

of improper accessories may cause

risk of injury to persons.

NEVER STAND ON TOOL. Serious18. injury could occur if the tool is tipped

or if the cutting tool is unintentionally

contacted.

CHECK DAMAGED PARTS. Before19. further use of the tool, a guard or

other part that is damaged should

be carefully checked to determine

that it will operate properly and per-

form its intended function – check for

alignment of moving parts, binding

of moving parts, breakage of parts,

mounting, and any other conditions

that may affect its operation. A guard

SKU 1624 For technical questions, please call 1-800-444-3353. Page 4

or other part that is damaged should

be properly repaired or replaced.

DIRECTION OF FEED. Feed work20. into a blade or cutter against the

direction of rotation of the blade or

cutter only.

NEVER LEAVE TOOL RUNNING21. UNATTENDED. TURN POWER OFF.

Don’t leave tool until it comes to a

complete stop.

GROUNDING INSTRUCTIONS

TO PREVENT

AND DEATH FROM

INCORRECT GROUNDING

WIRE CONNECTION

READ AND FOLLOW THESE

INSTRUCTIONS:

110-120 V~ Grounded Tools: Tools

with Three Prong Plugs

In the event of a malfunction or1. breakdown, grounding provides a

path of least resistance for electric

current to reduce the risk of electric

shock. This tool is equipped with an

electric cord having an equipment-

grounding conductor and a ground-

ing plug. The plug must be plugged

into a matching outlet that is properly

installed and grounded in accordance

with all local codes and ordinances.

Do not modify the plug provided – if it2.

will not t the outlet, have the proper

outlet installed by a qualied electri-

cian.

Improper connection of the equip-3. ment-grounding conductor can re-

sult in a risk of electric shock. The

conductor with insulation having an

outer surface that is green with or

without yellow stripes is the equip-

ment-grounding conductor. If repair

or replacement of the electric cord or

plug is necessary, do not connect the

equipment-grounding conductor to a

live terminal.

Check with a qualied electrician or 4. service personnel if the grounding

instructions are not completely under-

stood, or if in doubt as to whether the

tool is properly grounded.

Use only 3-wire extension cords that5. have 3-prong grounding plugs and

3-pole receptacles that accept the

tool’s plug.

Repair or replace damaged or worn6. cord immediately.

stantly.

The use of accessories or attach-7. ments not recommended by the

manufacturer may result in a risk of

injury to persons.

When servicing use only identical8. replacement parts.

Only use safety equipment that has9. been approved by an appropriate

standards agency. Unapproved

safety equipment may not provide

adequate protection. Eye protection

must be ANSI-approved and breath-

ing protection must be NIOSH-ap-

proved for the specic hazards in the

er failure.

WARNING: Some dust created by14. power sanding, sawing, grinding, drill-

ing, and other construction activities,

contains chemicals known [to the

State of California] 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 ce-

ment or other masonry products

• Arsenic and chromium from chemi-

cally treated lumber

Your risk from these exposures var-

ies, 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

SKU 1624 For technical questions, please call 1-800-444-3353. Page 6

those dust masks that are specially

designed to lter out microscopic

particles. (California Health & Safety

Code § 25249.5, et seq.)

WARNING: Handling the cord on15. this product will expose you to lead,

a chemical known to the State of

California to cause cancer, and birth

defects or other reproductive harm.

nia Health & Safety Code § 25249.5,

et seq.)

The warnings, precautions, and in-16. structions discussed in this instruction

manual cannot cover all possible con-

ditions and situations that may occur.

It must be understood by the operator

that common sense and caution are

factors which cannot be built into this

product, but must be supplied by the

Vibration Safety

This tool vibrates during use. Re-

peated or long-term exposure to

vibration may cause temporary or

permanent physical injury, particularly

to the hands, arms and shoulders. To

reduce the risk of vibration-related

injury:

Anyone using vibrating tools regu-1. larly or for an extended period should

rst be examined by a doctor and

then have regular medical check-

ups to ensure medical problems are

not being caused or worsened from

use. Pregnant women or people

who have impaired blood circulation

to the hand, past hand injuries, ner-

vous system disorders, diabetes, or

Raynaud’s Disease should not use

this tool. If you feel any medical or

physical symptoms related to vibra-

tion (such as tingling, numbness, and

white or blue ngers), seek medical

advice as soon as possible.

Do not smoke during use. Nico-2. tine reduces the blood supply to the

hands and ngers, increasing the risk

of vibration-related injury.

Wear suitable gloves to reduce the3. vibration effects on the user.

Use tools with the lowest vibration4. when there is a choice between dif-

ferent processes.

Include vibration-free periods each5. day of work.

Grip tool as lightly as possible (while6. still keeping safe control of it). Let

the tool do the work.

To reduce vibration, maintain the tool7. as explained in this manual. If any

abnormal vibration occurs, stop use

immediately.
