WARNING

To avoid electrical hazards, ﬁre hazards or damage to the tool, use proper

circuit protection.

This tool is wired at the factory for 110-120 Volt operation. It must be

connected to a 110-120 Volt / 15 Ampere time delay fuse or circuit breaker.

To avoid shock or ﬁre, replace power cord immediately if it is worn, cut or

damaged in any way.

Before using your tool, it is critical that you read and understand these

safety rules. Failure to follow these rules could result in serious injury to

you or damage to the tool.

WARNING

Some dust created by using power tools contains chemicals known to the state

of California to cause cancer and birth defects or other reproductive harm.

Some examples of these chemicals are:

●Lead from lead-based paints

●Crystalline silica from bricks, cement and other masonry

products

●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 dust

masks that are specially designed to ﬁlter out microscopic particles.

POWER TOOL SAFETY

GENERAL SAFETY INSTRUCTIONS

BEFORE USING THIS POWER TOOL

Safety is a combination of common

sense, staying alert and knowing how

to use your power tool.

CAUTION

To avoid mistakes that could cause

serious injury, do not plug the tool in

until you have read and understood

the following.

1. READ and become familiar

with the entire Operator’s

Manual. LEARN the tool’s

application, limitations and

possible hazards.

2. KEEP GUARDS IN PLACE and in

working order.

3. REMOVE ADJUSTING KEYS

AND WRENCHES. Form the habit

of checking to see that keys and

adjusting wrenches are removed

from the tool before turning ON.

4. KEEP WORK AREA CLEAN.

Cluttered areas and benches invite

accidents.

5. DO NOT USE IN DANGEROUS

ENVIRONMENTS. Do not use

power tools in damp locations, or

expose them to rain or snow. Keep

work area well lit.

6. KEEP CHILDREN AWAY. All

visitors and bystanders should be

kept a safe distance from work area.

7. MAKE WORKSHOP CHILD PROOF

with padlocks, master switches or by

removing starter keys.

8. DO NOT FORCE THE TOOL. It will

do the job better and safer at the

rate for which it was designed.

9. USE THE RIGHT TOOL. Do not

force the tool or an attachment to do

a job for which it was not designed.

10.USE PROPER EXTENSION

CORDS. 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 result in a drop

in line voltage and in loss of power

which will cause the tool to overheat.

The table on page 11 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.

11.WEAR PROPER APPAREL. Do

not wear loose clothing, gloves,

neckties, rings, bracelets or other

jewelry which may get caught in

moving parts. Nonslip footwear is

recommended. Wear protective hair

covering to contain long hair.

12.ALWAYS WEAR EYE

PROTECTION. Any power

tool can throw foreign

objects into the eyes and

could cause permanent

eye damage. ALWAYS wear Safety

Goggles (not glasses) that comply

with ANSI Safety standard Z87.1.

Everyday eyeglasses have only

impact–resistant lenses. They

ARE NOT safety glasses. Safety

Goggles are available at Sears.

NOTE: Glasses or goggles not in

compliance with ANSI Z87.1 could

seriously injure you when they break.

13.WEAR A FACE MASK OR DUST

MASK. Sawing operation produces

dust.

14.SECURE WORK. Use clamps or

a vise to hold work when

practical. It is safer than

using your hand and

it frees both hands to

operate the tool.

15.DISCONNECT TOOLS FROM

POWER SOURCE before servicing,

and when changing accessories

such as blades, bits and cutters.

16.REDUCE THE RISK OF

UNINTENTIONAL STARTING.

Make sure switch is in the OFF

position before plugging the tool in.

POWER TOOL SAFETY

17.USE RECOMMENDED

ACCESSORIES. Consult

this Operator’s Manual for

recommended accessories. The use

of improper accessories may cause

risk of injury to yourself or others.

18.NEVER STAND ON THE TOOL.

Serious injury could occur if the

tool is tipped or if the cutting tool is

unintentionally contacted.

19.CHECK FOR DAMAGED PARTS.

Before 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 perform 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 or other

part that is damaged should be

properly repaired or replaced.

20. NEVER LEAVE THE TOOL

RUNNING UNATTENDED. TURN

THE POWER “OFF”. Do not walk

away from a running tool until the

blade comes to a complete stop

and the tool is unplugged from the

power source.

21.DO NOT OVERREACH. Keep

proper footing and balance at all

times.

22. MAINTAIN TOOLS WITH CARE.

Keep tools sharp and clean for best

and safest performance. Follow

instructions for lubricating and

changing accessories.

23. WARNING: Dust generated from

certain materials can be hazardous

to your health. Always operate saw

in well-ventilated area and provide

for proper dust removal.

24.

People

with electronic devices, such as

pacemakers, should consult their

physician(s) before using this

product. Operation of electrical

equipment in close proximity to

a heart pacemaker could cause

interference or failure of the

pacemaker.

components with protecting insulation.

Replacement parts – When servicing,

use only identical replacement parts.

Polarized plugs – This saw has a plug

that looks like the one shown below:

To reduce the risk of electrical shock,

this saw has 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, reverse the plug. If it still does

not ﬁt, contact a qualiﬁed electrician to

install the proper outlet. Do not change

the plug in any way.

Double insulation does not take the

place of normal safety precautions

when operating this tool.

To avoid electrocution:

1. Use only identical replacement parts

when servicing a tool with double

insulation. Servicing should be

performed by a qualiﬁed technician.

2. Do not use power tools in wet or

damp locations or expose them to

rain or snow.

MOTOR SAFETY PROTECTION

IMPORTANT

To avoid motor damage, the motor

should be blown out or vacuumed

frequently to keep sawdust from

interfering with the motor ventilation.
