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 not 10.

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 a 12.

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 proper 13.

footing and balance at all times.

MAINTAIN TOOLS WITH CARE. 14.

CHECK DAMAGED PARTS. Before 19.

further use of the tool, a guard or

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 the 3.

vibration effects on the user.

Use tools with the lowest vibration 4.

when there is a choice between dif-

ferent processes.

Include vibration-free periods each 5.

day of work.

Grip tool as lightly as possible (while 6.

still keeping safe control of it). Let

the tool do the work.

To reduce vibration, maintain the tool 7.

as explained in this manual. If any

abnormal vibration occurs, stop use

immediately.

BASIC OPERATION

WARNING! Make sure the Power

Cord (102) of the Miter Saw is un-

plugged from its electrical outlet.

Then, if necessary, make adjustments

to the workpiece Holder (9), cutting

depth, miter angle, and bevel angle.

Raise the Saw Blade (56) up to allow 1.

positioning of the workpiece.

Check to make sure the Trigger (98) 2.

is operating properly.

Place the workpiece on the Table 3.

(18a) and against the Guide Fence

(37a).

Use the Clamp Assembly (36) to hold 4.

the workpiece in place.

Plug the Power Cord (102) into the 5.

nearest 120 volt, grounded, electri-

cal outlet.

Squeeze the Trigger (98) to turn on 6.

the Miter Saw.

When the Saw Blade (56) is turning 7.

at full speed, slowly bring down the

Motor Housing (75) to complete the

cut.
