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. Use in well ventilated areas only.
• 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 eliminates the need for the three 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 electric 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 clothing, jewelry, or long hair can be caught in moving parts. Air vents cover moving parts and should be avoided.
• 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 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, non-skid safety shoes, hard hat, or hearing protection must be used for appropriate conditions.

Tool Use and Care

• Use clamps or other practical way to secure and support 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 application. 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 the power source before making any adjustments, changing accessories, or storing the tool. Such preventative safety measures reduce the risk of starting the tool accidentally.
• Store idle tools out of 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 tools 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.

Service

• Tool service must be performed only by qualified repair personnel. Service or maintenance performed by unqualified personnel could result in a risk of injury.
• 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 follow Maintenance Instructions may create a risk of electric shock or injury.

Specific Safety Rules

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

AWARNING: 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 (CCA).

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.

• Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling, and other construction activities. Wear protective clothing and wash exposed areas with soap and water. Allowing dust to get into your mouth, eyes, or lay on the skin may promote absorption of harmful chemicals.

ACAUTION: Wear appropriate hearing protection during use. Under some conditions and duration of use, noise from this product may contribute to hearing loss.

ACAUTION: Do not touch the bit or collet nut during or immediately after cutting material. The bit and collet nut may be hot enough to burn bare skin.

WARNING: After changing bits or making any adjustments, make sure the collet nut is securely tightened to avoid injury.

WARNING: Do not press spindle lock while motor is running. The operator may lose control and drop the tool. Personal injury or serious tool damage may result.

WARNING: Shut off all live electric circuits to any areas where cut outs will be made, to avoid fire or serious personal injury.

Always wear eye protection. Dust mask or hearing protection must be used for appropriate conditions. Using personal safety devices is recommended. WORK SAFE.
- Always operate the tool with the depth guide in place. The guide keeps the bit from plunging too deeply through the material. A minimum of penetration should be maintained to eliminate the danger of cutting into electric wiring.
- Do not lay the tool down until the motor has come to a complete stop. The spinning motor may cause the tool to roll off a table or into a piece of material damaging the bit.
- Be sure your cutting bits are sharp

and in good condition. Damaged bits can cause the tool to jump injuring the operator.
- I'f your tool fails to function properly, take it to an authorized service center. There are no user serviceable parts inside this tool and it should only be opened by trained service personnel.

TO MAINTAIN SAFE TOOL CONTROL

Make sure the work surface is free of nails or screws. Cutting into a nail or screw may cause the tool to jump, damaging the bit.
- Never operate the tool with one hand while holding the workpiece with the other hand. Always clamp the material and guide the tool with both hands.
- Do not cut material lying on a hard surface. Clearance behind material to be cut must be allowed for protruding bit.
- Disconnect plug from power supply before making adjustments, changing bits, or cleaning tool.
- Do not start the tool with bit engaged in the material. The bit may grab the material.

USE OF EXTENSION CORDS

Make sure the extension cord is in good condition before using. Always use the proper size extension cords with the tool that is, proper wire size for various lengths of cord and heavy enough to carry the current the tool will draw. Use of an undersized cord will cause a drop in line voltage resulting in loss of power and overheating. For proper size cords see chart.

MOTOR

Be sure your power supply agrees with nameplate marking. 120 volts AC means your tool may be operated only with alternating current and never with direct current.

SWITCH (FIG. 1)

To start the motor, slide the switch (A) to "I" position. To stop the motor, slide the switch to "O" position.

INSTALLING AND REMOVING THE BIT (FIG. 2)

To change bits, FIRST turn off the tool and disconnect from power supply.

1. To replace bit, depress and hold spindle lock (B) and turn collet nut (C) counter clockwise with the wrench provided.
2. Remove old bit. CAUTION: Bit may be hot.
3. Insert new bit.

WARNING: The bits are sharp and should be handled with care.

CAUTION: When replacing bits, do not insert cutting flutes into the collet. This may result in broken bits.

1. While depressing spindle lock, turn the collet nut clockwise with the wrench to firmly tighten the collet.

CAUTION: Never tighten the collet without a bit installed.

NOTE: Rotary saw accessory bits can be stored in the wrench handle. See Fig. 3.

CHANGING THE COLLET (FIG. 4)

Some accessories require different sized collets. The two collets used with Black & Decker accessories are 1/8" and 1/4". The RS250 comes with both the 1/8" and 1/4" collets as standard equipment.

TO CHANGE THE COLLET:

ACAUTION: Collet may be hot.
1. Turn off tool, allow it to come to a complete stop and disconnect from power supply.
2. Depress and hold in spindle lock (B) and turn collet nut (C) counterclockwise with the wrench provided.
3. Remove the collet nut and collet from the threaded spindle (see Fig. 4).
4. Thread the new collet nut and collet onto the spindle.
5. Insert proper bit and securely tighten collet nut with wrench.
CAUTION: Never tighten the collet without a bit installed.

CAUTION: Remove bit from collet before installing or removing depth guide or handle.

Keep depth guide ((E) Fig. 5) in place at all times during operation of the tool. For best results, adjust the guide using lock knob ((F) Fig. 6) to allow the bit to protrude a minimum of 1/8 past the material to be cut. Whenever the handle has been removed and is being reattached, it is recommended that the depth guide and handle be aligned together. Loosely attach handle to depth guide and place both on a flat surface. Hold down the base of the depth guide to keep it even with the flat surface and tighten the knob of the handle as shown in Figure 7.

Operation

GENERAL CUTTING

A handy scale on the wrench (Fig.8) can be used to help determine the cutting depth. When plunge cutting, hold the tool firmly with both hands, insert the bit into the material at a 45^ angle. Slowly bring the tool to a 90^ angle to start the cut. When cutting from the edge of the workpiece, hold the tool 90^ to the work surface. With depth guide in contact with work surface, slowly bring bit into contact with edge. The depth guide should be kept in contact with the material being cut at all times. Move the tool in a clockwise direction using slow steady pressure to continue the cut. When the cut is completed allow the tool to come to a complete stop before lifting it from the material.

DUST BLOWER

To aid visibility when cutting, your rotary saw is equipped with a dust blower (Fig.6) which can be used to keep the work area clear of dust as you saw. It can also be turned to block the air flow if desired.

CUTTING A HOLE FOR AN

ELECTRICAL OUTLET (FIG. 9)

WARNING: Shut off all live electric circuits to any areas where cut outs will be made.

Install the followpoint bit shown here. It is designed specifically for use with cutting out outlet boxes.

1. Push any wiring deeply into the outlet

box to avoid damage from the cutting bit.

1. Before hanging the sheet covering the outlet, mark the approximate location of the center of the outlet on the wall board. Check the cutting bit depth against the side of the board to be sure it will cut entirely through the material.
2. Tack the sheet in place with a few fasteners avoiding the stud holding the outlet. This allows the wall board to flex slightly around the protruding fixture box.
3. Turn the rotary saw on. Holding the tool firmly with both hands, (Fig. 9) plunge the bit straight into the center of the outlet.
4. Cut to the right until the edge of the box is touched. Pull out just enough for the bit to clear the edge of the box. Plunge in again holding the bit gently against the outside of the box.
5. Follow the outside of the box (counterclockwise) as shown keeping slight pressure against the box. This will minimize wandering and give you a clean precise cut.

NOTE: This is opposite of the recommended clockwise direction for general cutting.

1. Remove the waste and dust from the outlet. Finish fastening the sheet of wall board.

MAINTENANCE

The tool should be cleaned with a blast of air often, to eject as much dust as possible. This will increase the life of the brushes and bearings inside the motor. Always use appropriate safety equipment when using compressed air to clean a tool. The brushes in this tool are replaceable and can be accessed through the panels on either side of the tool housing. Black and Decker recommends that brush replacement be performed by a company owned or authorized service center.

Although the tool's plastic case is solvent resistant, you should never use solvents or harsh chemicals to clean it. Wipe the non-metallic parts of the tool with a dry cloth.

IMPORTANT: To assure product SAFETY and RELIABILITY, repairs, maintenance and adjustment should be performed by authorized service centers or other qualified service personnel, always using identical replacement parts.

LUBRICATION

All bearings are factory lubricated for the life of the tool.
