INTRODUCTION

This tool has many features for making its use more pleasant and enjoyable. Safety, performance, and dependability have been given top priority in the design of this product making it easy to maintain and operate.

GENERAL SAFETY RULES

WARNING:

Read and understand all instructions. Failure to

follow all instructions listed below, may result in electric shock, fire and/or serious personal injury.

SAVE THESE INSTRUCTIONS WORK AREA

 Keep your work area clean and well lit. Cluttered

benches and dark areas invite accidents.

 Do not operate power tools in explosive atmospheres,

such as in the presence of flammable liquids, gases, or dust. Power tools create sparks which may ignite the

dust or fumes.

 Keep bystanders, children, and visitors away while

operating a power tool. Distractions can cause you to

lose control.

ELECTRICAL SAFETY

 Double insulated tools are equipped with 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 a polarized outlet. Do not change the plug in any way.

Double insulation wire grounded power cord and grounded power supply system.

 Avoid body contact with grounded surfaces such as

pipes, radiators, ranges, and refrigerators. There is an

increased risk of electric shock if your body is grounded.

 Don’t expose power tools to rain or wet conditions.

Water entering a power tool will increase the risk of elec tric shock.

 Do not abuse the cord. Never use the cord to carry the

tools or pull the plug from an outlet. Keep cord away from heat, oil, sharp edges, or moving parts. Replace damaged cords immediately. Damaged cords increase

the risk of electric shock.



When operating a power tool outside, use an outdoor extension cord marked “W-A” or “W”. These cords are rated

for outdoor use and reduce the risk of electric shock.

PERSONAL SAFETY

 Stay alert, watch what you are doing and use common

sense when operating a power tool. Do not use tool while tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating

power tools may result in serious personal injury.

 Dress properly. Do not wear loose clothing or jewelry.

Contain long hair. Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long

hair can be caught in moving parts.



Avoid accidental starting. Be sure switch is off before plugging in. Carrying tools with your finger on the switch

or plugging in tools that have the switch on invites accidents.

 Remove adjusting keys or wrenches before turning

the tool on. A wrench or a key that is left attached to a

rotating part of the tool may result in personal injury.

 Do not overreach. Keep proper footing and balance

at all times. Proper footing and balance enables better

control of the tool in unexpected situations.

 Use safety equipment. Always wear eye protection.

Dust mask, nonskid safety shoes, hard hat, or hearing protection must be used for appropriate conditions.

 Do not wear loose clothing or jewelry. Contain long

hair. Loose clothes, jewelry, or long hair can be drawn

into air vents.

 Do not use on a ladder or unstable support. Stable

footing on a solid surface enables better control of the tool in unexpected situations.

TOOL USE AND CARE

 Use clamps or other practical way to secure and sup-

port the workpiece to a stable platform. Holding the

work by hand or against your body is unstable and may lead to loss of control.

 Do not force tool. Use the correct tool for your appli-

cation. The correct tool will do the job better and safer

at the rate for which it is designed.

 Do not use tool if switch does not turn it on or off.

Any tool that cannot be controlled with the switch is dangerous and must be repaired.

 Disconnect the plug from power source before mak-

ing any adjustments, changing accessories, or storing

the tool. Such preventive safety measures reduce the risk of starting the tool accidentally.

 Store idle tools out of the reach of children and other

untrained persons. Tools are dangerous in the hands of

untrained users.

 Maintain tools with care. Keep cutting tools sharp

and clean. Properly maintained tools with sharp cutting

edges are less likely to bind and are easier to control.

 Check for misalignment or binding of moving parts,

breakage of parts, and any other condition that may affect the tool’s operation. If damaged, have the tool serviced before using. Many accidents are caused by

poorly maintained tools.

 Use only accessories that are recommended by the

manufacturer for your model. Accessories that may be

suitable for one tool, may become hazardous when used on another tool.

 Keep the tool and its handle dry, clean and free from

oil and grease. Always use a clean cloth when clean-

ing. Never use brake fluids, gasoline, petroleum-based products, or any strong solvents to clean your tool. Following this rule will reduce the risk of loss of control and deterioration of the enclosure plastic.

GENERAL SAFETY RULES

SERVICE

 Tool service must be performed only by qualified re-

pair personnel. Service or maintenance performed by

unqualified personnel may result in a risk of injury.

SPECIFIC SAFETY RULES

 DANGER! Keep hands away from cutting area and

blade. Keep your second hand on the auxiliary handle, or motor housing. If both hands are holding the saw,

they cannot be cut by the blade.

 Keep your body positioned to either side of the saw

blade, but not in line with the saw blade. Kickback

could cause the saw to jump backwards. (See “Causes and Operator Prevention of Kickback.”)

 Do not reach underneath the work. The guard can not

protect you from the blade below the work.

 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 ac-

cidentally dropped, lower guard may be bent. Raise the lower guard with the Retracting Handle and make sure it moves freely and does not touch the blade or any other part, in all angles and depths of cut.

 Check the operation and condition 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 “Pocket Cuts” and “Compound Cuts.” Raise lower guard by retracting handle. As soon as blade enters the material, 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 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.

 NEVER hold piece being cut in your hands or across

your leg. It is important to support the work properly to

minimize body exposure, blade binding, or loss of control.

 Hold tool by insulated gripping surfaces when per-

forming 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 the cut and reduces

the chance for blade binding.

 When servicing a tool, use only identical replacement

parts. Follow instructions in the Maintenance section of this manual. Use of unauthorized parts or failure to fol-

low Maintenance Instructions may create a risk of shock or injury.

 Always use blades with correct size and shape (dia-

mond vs. round) arbor holes. Blades that do not match

the mounting hardware of the saw will run eccentrically, causing loss of control.

 Never use damaged or incorrect blade washers or

bolts. The blade washers and bolts were specially de-

signed for the saw for optimum performance and safety of operation.

CAUSES AND OPERATOR PREVENTION OF KICKBACK

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 kerf clos ing 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 tool 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 body and arm to allow you to resist KICKBACK forces. 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 blade is binding,

it may walk up or KICKBACK from the workpiece as the saw is restarted.

 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.

SPECIFIC SAFETY RULES

 Do not use dull or damaged blade. 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 ad-

justment shifts while cutting, it may cause binding and KICKBACK.

 Use extra caution when making a “Pocket Cut” into

existing walls or other blind areas. The protruding blade

may cut objects that can cause KICKBACK.

ADDITIONAL SAFETY RULES

 Inspect tool cords periodically and, if damaged, have

repaired at your nearest Authorized Service Center. Constantly stay aware of cord location. Following this

rule will reduce the risk of electric shock or fire.

 Check 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 by an authorized service center. Following this rule will

reduce the risk of shock, fire, or serious injury.

 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. A wire gage size (A.W.G.) of at least 12 is recommended for an extension cord 50 feet or less in length. A cord exceeding 50 feet is not recommended. If in doubt, use the next heavier gage. The smaller the gage number, the heavier the cord. An undersized cord

will cause a drop in line voltage resulting in loss of power and overheating.

 Inspect for and remove all nails from lumber before

using this tool. Following this rule will reduce the risk of

serious personal injury.

 Drugs, alcohol, medication. Do not operate tool while

under the influence of drugs, alcohol, or any medication. Following this rule will reduce the risk of electric

shock, fire, or serious personal injury.

 If the power supply cord is damaged, it must be re-

placed only by the manufacturer or by an authorized service center to avoid risk.

 Save these instructions. Refer to them frequently and use

them to instruct others who may use this tool. If you loan someone this tool, loan them these instructions also.

WARNING:

Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known 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 cement and other masonry products, and

• 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 those dust masks that are specially designed to filter out microscopic particles.

ELECTRICAL

DOUBLE INSULATION

Double insulation is a concept in safety in electric power tools, which eliminates the need for the usual three-wire grounded power cord. All exposed metal parts are isolated from the internal metal motor components with protecting insulation. Double insulated tools do not need to be grounded.

WARNING:

The double insulated system is intended to protect the user from shock resulting from a break in the tool’s internal wiring. Observe all normal safety precautions to avoid electrical shock.

Servicing of a tool with double insulation requires extreme care and knowledge of the system and should be performed only by a qualified service technician. For service, we suggest you return the tool to your nearest authorized service center for repair. Always use original factory replacement parts when servicing.

ELECTRICAL CONNECTION

This tool has a precision-built electric motor. It should be connected to a power supply that is 120 volts, 60 Hz, AC only (normal household current). Do not operate this tool on direct current (DC). A substantial voltage drop will cause a loss of power and the motor will overheat. If your tool does not operate when plugged into an outlet, double-check the power supply.

EXTENSION CORDS

When using a power tool at a considerable distance from a power source, be sure to use an extension cord that has the capacity to handle the current the tool will draw. An undersized cord will cause a drop in line voltage, resulting in overheating and loss of power. Use the chart to determine the minimum wire size required in an extension cord. Only round jacketed cords listed by Underwriter’s Laboratories (UL) should be used.

When working outdoors with a tool, use an extension cord that is designed for outside use. This type of cord is designated with “WA” on the cord’s jacket.

Before using any extension cord, inspect it for loose or ex posed wires and cut or worn insulation.
