Special

BEFORE USING THE SAW:

1. Assembly and alignment.

2. Learn the function and proper use of:

A. The on-off switch.

B. The upper and lower blade guards.

C, The arbor lock and handle latch.

D. The bevel clamp, fence clamps, and miter

lock handle.

3. Read and understand all safety instructions and'

operating procedures throughout the manual.

4. Read the warning label on the miter saw,

WHEN INSTALLING OR MOVING

THE SAW:

1, To avoid injury from unexpected saw movement'.

A. Place the saw on a firm level surface where

there is plenty of room for handling and

properly supporting the workplace.

B. Support the saw so the table is level and the

saw does not rock.

C. Bolt or clamp the saw to its support,

2, Before moving the saw, lock the miter, bevel

and power-head positions. Unplug electric cord.

3, To avoid back injury, get help when you need to

lift the saw more than 10 inches. Hold the tool

close to your body. Bend your knees so you can

lift with your legs, not your back. Lilt by using

the hand-hold areas at the bottom of the base.

Never carry the tool by the cord or power head

handle. Damage to insulation could cause an

electric shock. Damage to wire connections

could cause a fire.

BEFORE EACH USE:

1. Inspect your saw. If any part of this miter saw is

missing, or bent, or has failed in any way, or

any electrical parts don't work properly, turn the

saw off and unplug the saw. Replace damaged,

missing, or failed parts before using the saw

again.

2. Plan Your Work to protect your eyes, hands,

face, and ears.

A. Wear safety goggles (not glasses) that

comply with ANStZ87,1(shown on package).

Using any power tool can result in foreign

objects being thrown into the eyes, which

can result in permanent eye damage. Safety

goggles are available at stores. Use of

glasses or use of goggles not in compliance

with ANSiZ87.1 could result in severe injury

from breakage of the eye protection.

WEAR YOUR

B. For dusty operations, wear a face shield

along with safety goggles.

C. To avoid injury from jams, slips or thrown

pieces:

@Choose the right 10-inch diameter blade for

the material and the type of cutting you

ptan to do. Use this miter saw to cut only

wood, wood-like products or soft metals

like aluminum. Other materials may sha-

tter, grab at the blade, or create other

dangers.

eMake sure the direction of rotation arrow

on the blade matches the direction arrow

on the saw. The blade teeth should always

point downward at the front of the saw.

eMake sure the blade is sharp, undamaged

and properly aligned. With the saw un-

plugged, push the power-head all the way

down, Hand spin the blade and check for

clearance. Tilt the power-head to 45 degree

bevel and repeat the check, if the blade hits

anything, make the adjustments shown in

the Maintaining Maximum Cutting Capacity

section,

eMake sure the blade and arbor collars are

clean.

• Make sure the collars' recessed sides are

facing toward the blade.

eMake sure the recessed side of the blade

washer (just under the arbor screw head)

faces the collar.

eUsing 1/2-inch box end wrench, make sure

the arbor cap screw retaining the blade

collars is firmly hand tightened.

eMake sure all clamps and locks are tight

and there is no excessive play in any parts.

• Never cut FREEHAND:

a. Brace your workplace solidly against the

fence and table top so it will not rock or

twist during the cut. Make sure no

debris is caught beneath_the workpiece.

b. Make sure no gaps between the work-

piece, fence and table will let the

workpiece shift after it is cut in two.

co Use jigs, fixtures or a different tool for

unstable workpieces.

• Never cut more than one workplace at a time.

• Make sure the cut off piece C_n move

sideways after it's cut off. Otherwise, it could

get wedged against the blade and thrown

violently. .............._ ,_;_

blocks, etc,)for any workpieces large enou-

gh to tip when not held down to the tabte

top.

b. Do not use this saw to cut pieces too small

to let you easily hold the work while you

keep the thumb side of your index (poi-

nter) finger against the outside edge of the

fence.

c. When cutting irregularly shaped work*

pieces, plan your work so it will not slip

and pinch the blade. A piece of motding,

for example, must lie flat or be held by a

fixture or jig that will not let it twist, rock

or slip while being cut.

d. Properly support round material such as

dowel rods, or tubing. They have a

tendency to roll while being cut, causing

the blade to _bite. _ To avoid this, always

use a fixture designed to properly hold

your work piece.

• Make sure there are no nails or foreign

objects in the part of the workpiece to be cut.

• Make sure bystanders are clear of the tool and

workpiece. Keep them clear of the area behind

the saw where debris will be thrown.

• Never turn your miter saw _ON_ before

clearing everything except the workpiece and

related support devices off the table.

D. To avoid risk of hearing damage, wear ear

plugs or muffs during extended periods of

operation.

E, To avoid being suddenly pufled into the blade:

1. Do not wear gloves.

2. Remove all jewelry and loose clothing.

3. Tie back long hair.

4. Rol! long sleeves above the elbow.

G, To avoid an electrical shock, make sure your

fingers do not touch the metal prongs on the

plug when inserting or removing the plug to

or from a live outlet.

H. Never put lubricants on the blade while it's

spinning,

1.To avoid burns or other fire damage, never

use the saw near flammable liquids, vapors or

gases.

J. To avoid injury from unsafe accessories, use

only accessories shown on the recommended

accessories list in this manual.

WHENEVER SAW IS RUNNING:

ii =ii i i =========lllll

I WARNING: Don't allow familiarity (gained trom

Irequent use of your miter saw) to cause a careless

mistake. Always remember that a careless fraction

....#fa second is enough,, t,o cause a severe injury.

1. Before actually cutting with the saw, let it run

for a while. If your saw makes an unfamiliar

noise or if it vibrates excessively, stop immedi-

ately. Turn the saw off. Unplug the saw. Do not

restart until finding and correcting the problem,

2. Never confine the piece being cut off. Never

hold it, clamp it, touch it, or use length stops

against it. It must be free to move sideways. If

confined, it could get wedged against the blade

and thrown violently.

3. Avoid awkward hand positions where a sudden

slip could cause a hand to move into the blade.

4, Let the blade reach ful! speed before cutting.

5. Feed the saw into the workpiece only fast

enough to let the blade cut without bogging

down or binding,

6. Before freeing jammed material, release switch

and unplug the saw. Wait for all moving parts to

stop.

7. After finishing a cut, keep holding the power-

head down, release the switch, and wait for all

moving parts to stop before moving your hands,

DOUBLE INSULATED

The miter saw is double insulated to provide a

double thickness of insulation between you and the

tool's electrical system. All exposed metal parts

are isolated from the internal metal motor compo-

i nents with protective insulation,

Your unit has a plug that looks like the one shown

below

This power tool is equipped with a 2-conductor

cord listed by Underwriters Laboratories (UL). The

plug permits you to use any conventional 120-volt

electrical outlet without necessity for maintaining a

ground connection.

CAUTION: Double insulation does not take the

place of normal safety precautions when operating

this tool.

DANGER: To avoid electrocution:

1. Use only identical replacement parts when

servicing a tool with double insulation. Servicing

should be performed by a qualified service

technician,

2. Do not use in rain or where floor is wet,

This toot is intended for indoor residential use

only.

MOTOR SAFETY PROTECTION

CAUTION: Toavoid motor damage, this motor

should be blown out or vacuumed frequently to

keep sawdust from interfering with normal motor

ventilation.

1, Connect this tool to a 120V, 15-amp branch

circuit with a 15-amp time delay fuse or circuit

breaker.Using the wrong size fuse can damage

the motor.

2. If the motor won't start, release the trigger

switch immediately. UNPLUG THE TOOL, Check

the saw blade to make sure it turns freely. If the

blade is free, try to start the motor again. If the

motor still does not start, refer to the "MotOr

Trouble-Shooting Chart."

3, It the motor suddenly stalls while cutting wood,

release the trigger switch, unplug the tool, and

free the blade from the wood, Then you may

restart the motor and finish the cut.

4 Fuses may "blow"or circuit breakers may trip

frequently if:

a, MOTOR IS OVERLOADED-Overloading can

occur if you feed too rapidly or make too

many start/stops in a short time,

b. Voltages not more than 10_ above or below

the nameplate voltage can handle normal

loads. For heavy loads, however, the voltage

at motor terminals must equal the voltage

specified on nameplate

5 Most motor troubles may be traced to loose or

incorrect connections, overload, tow voltage

(such as small size wire in the supply circuit) or

to overly long supply circuit wire, Always check

the connections, the load and the supply circuit

whenever motor doesn't work well. Check wire

sizes and length with the Wire Size Chart below,

WIRE SIZES

The use of any extension coro ¢ilt cause some

toss of power. To keep this to a minimum and to

prevent overheating and motor burn-out, use the

table below to determine the minimum wire size

(A.W.G.) extension cord.

For circuits that are farther than 100 feet away

from electrical service box, the wire size must be

increased proportionately in order to deliver ample

voltage to the saw motor.
