in the Maintenance section of this manual. Use of unauthorized parts or failure to follow

Maintenance instructions may create a risk of shock or injury.,

[] Hold power tools by insulated gripping surfaces when performing an operation where

the cutting toot may contact hidden wiring or its own cord. Contact with a "live" wire will

also make exposed metal parts of the tool "live" and shock the operator°

[] Use clamps or another practical way to secure and support the workpiece to a stable platform.

Holding the work by hand or against your body leaves it unstable and may lead to loss of control,

[] Know your power tool. Read operator's manual carefully. Learn its applications and

limitations, as well as the specific potential hazards related to this tool. Following this

rule will reduce the risk of electric shock, fire or serious injury.

[] Always wear safety glasses with side shields. Everyday glasses have only impact resistant

[] Protect your lungs. Wear a face or dust mask if the operation is dusty. Following this rule

will reduce the risk of serious personal injury

[] Protect your hearing. Wear hearing protection during extended periods of operation.

Following this rule will reduce the risk of serious person injury°

[] Battery tools do not have to be plugged into an electrical outlet; therefore, they are

always in operating condition. Be aware of possible hazards when not using your

battery toot or when changing accessories. Following this rule will reduce the risk of electric

shock, fire or serious personal injury_

[] Do not place battery tools or their batteries near fire or heat. This will reduce the risk of

explosion and possibly injury_

[] Do not crush, drop or damage battery pack. Do not use a battery pack or charger that

has been dropped or received a sharp blow. A damaged battery is subiect to explosion.

Properly dispose of a dropped or damaged battery immediately.

I_I Batteries vent hydrogen gas and can explode in the presence of a source of ignition

such as a pilot light. To reduce the risk of serious personal injury, never use any cordless

product in the presence of open flame. An exploded battery can propel debris and chemicals, If

exposed, flush with water immediately

[] Do not charge battery tool in adamp or wet location. Following this rule will reduce the

risk of electric shock.

[] For best results, your battery tool should be charged in a location where the temperature

is more that 32°F (0°C) but less that 104°F (40°C). Do not store outside or in vehicles.

[] Under extreme usage or temperature conditions, battery leakage may occur. If liquid

comes in contact with your skin, wash immediately with soap and water, then neutralize

with lemon juice or vinegar. If liquid gets in your eyes, flush them with clean water for at

least 10 minutes, then seek immediate medical attention_ Following this rule wilt reduce the

risk of serious personal injury,

[] Save these instructions, Refer to them frequently and use them to instruct others who may

use this tool.. If you loan someone this tool, also loan them these instructions_

[] If the power supply cord is damaged, it must be replaced only by the manufacturer or by an

authorized service center to avoid risk.

[] DANGER! Keep hands away from cutting area and the blade. Keep your second hand

on auxiliary handle or motor housing. If both hands are holding the saw, they cannot be cut

by the blade°

I_ Do not reach underneath the workpiece. The guard cannot protect you from the blade below the

workpiece.

[] Adjust the cutting depth to the thickness of the workpiece. Less than a full tooth of the

blade teeth should be visible below the workpieceo

[] Never hold piece being cut in your hands or across your leg. Secure the workpiece to a

stable platform. It is important to support the work properly to minimize body exposure, blade

binding or loss of control

[] Hold power tools by insulated gripping surfaces when performing an operation where

the cutting tool may contact hidden wiring or its own cord. Contact with a "live" wire will

also make exposed metal parts of the tool "live" and shock the operator.

[] When ripping, always use a rip fence or straight edge guide. This improves the accuracy

of cut and reduces the chance of blade binding

[] Always use blades with the correct size and shape (diamond versus round) of arbor

holes. Blades that do not match the mounting hardware of the saw will run erratically, causing

loss of control°

[] Never use damaged or incorrect blade washers or bolt. The blade washers and bolt were

specially designed for your saw for optimum performance and safety of operation.

[] If the power supply cord is damaged, it must be replaced only by the manufacturer or by an

authorized service center to avoid risk

CAUSES AND OPERATOR PREVENTION OFKICKBACK:

Kickback is a sudden reaction to a pinched, bound or misaligned saw blade, causing an

uncontrolled saw to lift up and out of the workpiece toward the operator. When the blade is

pinched or bound tightly by the kerr closing down, the blade stalls and the motor reaction drives

the unit rapidly back toward the operator. If the blade becomes twisted or misaligned in the cut,

the teeth at the back edge of the blade can dig into the top surface of the wood causing the blade

to climb out of the kerf and jump back toward the operator, Kickback is the result of misuse and/

or incorrect operating procedures or conditions and can be avoided by taking proper precautions,

as given below:

[] Maintain a firm grip with both hands on the saw and position your arms to resist

kickback forces. Position your body to either side of the blade, but not in line with

the blade. Kickback could cause the saw to jump backwards, but kickback forces can be

controlled by the operator, if proper precautions are taken

[] When blade is binding or when interrupting a cut for any reason, release the trigger and

hold the saw motionless in the material until the blade comes to a complete stop. Never

attempt to remove the saw from the work or pull the saw backward while the blade is in

motion or kickback may occur. Investigate and take corrective actions to eliminate the cause

of blade binding

[] When restarting a saw in the workpiece, center the saw blade in the kerf and check that

saw teeth are not engaged into the material. If saw is binding, it may walk up or kickback

from the workpiece as the saw is restarted

m Support large panels to minimize the risk of blade pinching and kickback. Large panels

tend to sag under their own weight. Supports must be placed under the panel on both sides,

near the line of cut and near the edge of the panel.

[] Do not use dull or damaged blades. Unsharpened or improperly set blades produce narrow

kerf causing excessive friction, blade binding and kickback_

[] Blade depth and bevel adjusting locking levers must be tight and secure before making

cut. If blade adjustment shifts while cutting, it may cause binding and kickback.

[] Use extra caution when making a "plunge cut" into existing walls or other blind areas.

The protruding blade may cut objects that can cause kickback_

[] Check lower guard for proper closing before each use. Do not operate saw if lower

guard does not move freely and close instantly. Never clamp or tie the lower guard into

the open position. If saw is accidentally dropped, lower guard may be bent° Raise the lower

blade guard with the retracting handle. Make sure it moves freely and does not touch the blade

or any other part, in alt angles and depths of cut

[] Check the operation of the lower guard spring. If the guard and the spring are not

operating properly, they must be serviced before use. Lower guard may operate sluggishly

due to damaged parts, gummy deposits or a buildup of debris.

[] Lower guard should be retracted manually only for special cuts such as "plunge cuts"

and "compound cut." Raise lower blade guard by retracting handle. As soon as blade

enters the material, the lower guard must be released. For all other sawing, the lower

guard should operate automatically,

[] Always observe that the lower guard is covering the blade before placing the saw down

on bench or floor. An unprotected, coasting blade will cause the saw to walk backwards,

cutting whatever is in its path° Be aware of the time it takes for the blade to stop after switch is

released,,

[] Know your power tool. Read operator's manual carefully. Learn its applications and

limitations, as well as the specific potential hazards related to this tool. Following this

rule will reduce the risk of electric shock, fire or serious injury.

[] Always wear safety glasses with side shields. Everyday glasses have only impact resistant

lenses. They are NOT safety glasses. Following this rule wellreduce the risk of eye injury_

[] Protect your lungs. Wear a face or dust mask If the operation is dusty. Following this rule

will reduce the risk of serious personal injury_

[] Protect your hearing. Wear hearing protection during extended periods of operation.

Following this rule will reduce the risk of serious person injury_

[] Battery tools do not have to be plugged into an electrical outlet; therefore, they are

always in operating condition. Be aware of possible hazards when not using your

battery tool or when changing accessories. Following this rule will reduce the risk of electric

shock, fire or serious personal injury_
