GENERAL SAFETY RULES

WARNING! Read all instructions. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury. The term “power tool” in all of the warnings listed below refers to yourmains-operated(corded) power tool orbattery-operated(cordless) power tool.

SAVE THESE INSTRUCTIONS

1)Work area safety

a)Keep work area clean and well lit. Cluttered or dark areas invite accidents.

b)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.

c)Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control

2)Electrical safety

a)Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock

b)Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.

c)Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock

d)Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts.

Damaged or entangled cords increase the risk of electric shock.

e)When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.

3)Personal safety

a)Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tool may result in serious personal injury.

b)Use safety equipment. Always wear eye protection. Safety equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.

c)Avoid accidental starting. Ensure the switch is in the off-positionbefore plugging in.Carrying power tools with your finger on the switch or plugging in power tools that have the switch on invites accidents.

d)Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.

e)Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.

f)Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts. Air vents often cover moving parts and should also be avoided.

g)If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of these devices can reduce dust-related hazards.

4)Power tool use and care

a)Do not force the power tool. Use the correct power tool for your application.

The correct power tool will do the job better and safer at the rate for which it was designed.

2

90520983 VPX1301 Cut SAW 7/19/07 3:03 PM Page 3

b)Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.

c)Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.

d)Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool.

Power tools are dangerous in the hands of untrained users.

e)Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tools operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.

f)Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.

g)Use the power tool, accessories and tool bits etc., in accordance with these instructions and in the manner intended for the particular type of power tool, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.

5)Battery tool use and care

a)Ensure the switch is in the off position before inserting battery pack. Inserting the battery pack into power tools that have the switch on invites accidents.

b)Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.

c)Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.

d)When battery pack is not in use, keep it away from other metal objects like paper clips, coins, keys, nails, screws, or other small metal objects that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.

e)Under abusive conditions, liquid may be ejected from the battery, avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.

6)Service

a)Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.

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.

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.

When working on a ladder or on scaffolding be sure to lay the tool down on its side when not in use. Some tools with large battery packs will stand upright but may be easily knocked over.

Keep hands away from cutting area. Never reach underneath the material for any reason. Hold front of saw by grasping the contoured gripping area. Do not insert fingers or thumb into the vicinity of the reciprocating blade and blade clamp. Do not stabilize the saw by gripping the shoe.

Keep blades sharp. Dull blades may cause the saw to swerve or stall under pressure.

3

90520983 VPX1301 Cut SAW 7/19/07 3:03 PM Page 4

When cutting pipe or conduit ensure that they are free from water, electrical wiring, etc.

Do not touch the workpiece or the blade immediately after operating the tool. They can become very hot.

Do not use in rain or wet conditions.

WARNING: ALWAYS USE SAFETY GLASSES.Everyday eyeglasses are NOT safety glasses. Also use face or dust mask if cutting operation is dusty. ALWAYS WEAR CERTIFIED SAFETY EQUIPMENT:

ANSI Z87.1 eye protection (CAN/CSA Z94.3)

ANSI S12.6 (S3.19) hearing protection

NIOSH/OSHA respiratory protection

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-basedpaints,

crystalline silica from bricks and cement and other masonry products, and

arsenic and chromium from chemically-treatedlumber (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.

WARNING: Use of this tool can generate and/or disperse dust, which may cause serious and permanent respiratory or other injury.Always use NIOSH/OSHA approved respiratory protection appropriate for the dust exposure. Direct particles away from face and body.

When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. The following table shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gage. The smaller the gage number, the heavier the cord.

IMPORTANT SAFETY INSTRUCTIONS FOR BATTERY CHARGERS

SAVE THESE INSTRUCTIONS: This manual contains important safety instructions for battery chargers.

Before using charger, read all instructions and cautionary markings on charger, battery pack, and product using battery pack.

WARNING: Burn hazard. To reduce the risk of injury, charge onlyBlack & Decker VPXTM

batteries. Other types of batteries may burst causing personal injury and damage.

CAUTION: Under certain conditions, with the charger plugged in to the power supply, the charger can be shorted by foreign material. Foreign materials of a conductive nature such as, but not limited to, steel wool, aluminum foil, or any buildup of metallic particles should be kept away from charger cavities. Always unplug the charger from the power supply when there is no battery pack in the cavity. Unplug charger before attempting to clean. WARNING: Shock hazard. Do not allow any liquid to get inside charger.

DO NOT attempt to charge the battery pack with anything other than a

Black & Decker VPXTM branded charger. Black & Decker VPXTM chargers and battery packs are specifically designed to work together.

These chargers are not intended for any uses other than charging

Black & Decker VPXTM rechargeable batteries.Any other uses may result in risk of fire, electric shock or electrocution.

Do not expose charger to rain or snow.

Pull by plug rather than cord when disconnecting charger or when disconnecting cords using the daisy chain feature. This will reduce risk of damage to electric plug and cord.

Make sure that cord is located so that it will not be stepped on, tripped over, or otherwise subjected to damage or stress.

6

90520983 VPX1301 Cut SAW 7/19/07 3:03 PM Page 7

Do not use an extension cord unless it is absolutely necessary. Use of improper extension cord could result in risk of fire, electric shock, or electrocution.

An extension cord must have adequate wire size (AWG or American Wire Gauge) for safety. The smaller the gauge number of the wire, the greater the capacity of the cable, that is 16 gauge has more capacity than 18 gauge. When using more than one extension to make up the total length, be sure each individual extension contains at least the minimum wire size.

Do not operate charger with damaged cords or plugs — have them replaced immediately.

Do not operate charger if it has received a sharp blow, been dropped, or otherwise damaged in any way.

Do not disassemble charger. Incorrect reassembly may result in a risk of electric shock, electrocution or fire.

Disconnect the charger from the outlet before attempting any cleaning. This will reduce the risk of electric shock. Removing the battery pack will not reduce this risk.

The charger is designed to operate on standard household electrical power (120 Volts). Do not attempt to use it on any other voltage.

See instruction manual for use in countries other than the U.S.A.

This power unit is intended to be correctly orientated in a vertical or floor mount position.

SAVE THESE INSTRUCTIONS

INTRODUCTION

Black & Decker VPXTM chargers are designed to charge Black & Decker VPXTM battery packs in approximately 5-6 hours. The charger requires no adjustment and is designed to be as easy as possible to operate. Simply place your battery pack into the receptacle of a plugged in charger and it will automatically charge the pack. As you add new chargers to your Black & Decker VPXTM system, utilize the “daisy chain” feature to power multiple chargers from a single outlet.

IMPORTANT SAFETY INSTRUCTION FOR BATTERY PACKS

WARNING: For safe operation, read this manual and manuals originally supplied with tool before using the charger.

The battery pack is not fully charged out of the carton. Before using the battery pack and charger, read the safety instructions below. Then follow charging procedures outlined.

READ ALL INSTRUCTIONS

Do not incinerate the battery pack even if it is severely damaged or is completely worn out. The battery pack can explode in a fire. Toxic fumes and materials are created when lithium ion battery packs are burned.

Do not charge or use battery in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Inserting or removing the battery from the charger may ignite the dust or fumes.

If battery contents come into contact with the skin, immediately wash area with mild soap and water. If battery liquid gets into the eye, rinse water over the open eye for 15 minutes or until irritation ceases. If medical attention is needed, the battery electrolyte is composed of a mixture of liquid organic carbonates and lithium salts.

Contents of opened battery cells may cause respiratory irritation. Provide fresh air. If symptoms persists, seek medical attention.

WARNING: Burn hazard. Battery liquid may be flammable if exposed to spark or flame.

Charge the battery packs only in Black & Decker VPXTM chargers.

DO NOT splash or immerse in water or other liquids. This may cause premature cell failure.

Do not store or use the tool and battery pack in locations where the temperature may reach or exceed 105°F (40˚C) (such as outside sheds or metal buildings in summer).

WARNING: Never attempt to open the battery pack for any reason. If battery pack case is cracked or damaged, do not insert into charger. Do not crush, drop or damage battery pack. Do not use a battery pack or charger that has received a sharp blow, been dropped, run over or damaged in any way (i.e., pierced with a nail, hit with a hammer, stepped on). Damaged battery packs should be returned to service center for recycling.

7

90520983 VPX1301 Cut SAW 7/19/07 3:03 PM Page 8

WARNING: Fire hazard. Do not store or carry battery so that metal objects can contact exposed battery terminals.For example, do not place battery in aprons, pockets, tool boxes, product kit boxes, drawers, etc., with loose nails, screws, keys, etc.

Transporting batteries can possibly cause fires if the battery terminals inadvertently come in contact with conductive materials such as keys, coins, hand tools and the like. The US Department of Transportation Hazardous Material Regulations (HMR) actually prohibit transporting batteries in commerce or on airplanes (i.e., packed in suitcases and carry-on luggage) UNLESS they are properly protected from short circuits. So when transporting individual batteries, make sure that the battery terminals are protected and well insulated from materials that could contact them and cause a short circuit.

STORAGE RECOMMENDATIONS

1.Always store batteries charged.

2.The best storage place is one that is cool and dry away from direct sunlight and excess heat or cold.

3.Recharge discharged batteries as soon as possible after use or battery life may be greatly diminished.

CHARGING PROCEDURE

1.Plug the charger into an appropriate outlet before inserting the battery pack.

2.Insert the battery pack into the charger (figure B).Be sure the pack is fully

seated in the charger. While charging, the red (charging) LED will flash continuously (slowly) indicating that the charging process has started.

3.The completion of charge is indicated by the red LED becoming solid. (approximately 5-6hours) The pack is fully charged and may be used at this time or left on the charger.

4.Recharge discharged batteries as soon as possible after use or battery life may be greatly diminished.

CHARGE INDICATORS

Replace Pack:

These chargers are designed to detect certain problems that can arise with battery packs which would be indicated by the red light flashing at a fast rate. If this occurs,re-insertbattery pack. If problem persists, try a different battery pack to determine if the charger is OK. If the new pack charges correctly, then the original pack is defective and should be returned to a service center for recycling. If the new battery pack gives the same trouble indication as the original, have charger tested at an authorized service center. Note: It may take as long as fifteen minutes for the charger to determine that the pack is defective.

If the battery pack is too hot or too cold, the LED will alternately blink fast and slow, one flash at each speed and repeat.

DAISY CHAIN (FIGURE C)

Single and dual port chargers can be electrically connected in any order up to a maximum of 4 chargers. Each charger has a power-incord (which plugs into the electrical outlet) and apower-outcord (which plugs into the next charger).

To connect chargers in a daisy chain:

1.Plug the power-incord into an electrical outlet.

2.Remove the power-incord from the next charger and plug in thepower-outcord from the charger that is now plugged into the outlet.

3.Repeat this process for the remaining chargers.

Chargers that are daisy chained together operate independently as though each one was plugged into a sperate outlet therefore a battery can be removed from anywhere along the daisy chain without affecting the other chargers.

LEAVING THE BATTERY IN THE CHARGER

The charger and battery pack can be left connected indefinitely with the LED illuminated. You may see the LED return to flashing (charging) state, as the charger will occasionally “top off “ the battery charge.

8

90520983 VPX1301 Cut SAW 7/19/07 3:03 PM Page 9

IMPORTANT CHARGING NOTES

1.Longest life and best performance can be obtained if the battery pack is charged when the air temperature is between 65°F and 75°F (18°C- 24°C). DO NOT charge the battery pack in an air temperature below +40°F (+4.5°C), or above +105°F (+40.5°C). This is important and will prevent serious damage to the battery pack.

Note: The charger will not charge a battery pack if the pack temperature is below approximately 32°F (0°C) or above 122°F (50°C). The battery pack should be left in the charger and the charger will begin to charge automatically when the cell temperature warms up or cools down.

2.The charger and battery pack may become warm to touch while charging. This is a normal condition, and does not indicate a problem. To facilitate the cooling of the battery pack after use, avoid placing the charger or battery pack in a warm environment such as in a metal shed, or an uninsulated trailer.

3.If the battery pack does not charge properly:

a.Check current at receptacle by plugging in a lamp or other appliance

b.Check to see if receptacle is connected to a light switch which turns power off when you turn out the lights.

c.Move charger and battery pack to a location where the surrounding air temperature is approximately 65°F - 75°F (18°C- 24°C).

d.If charging problems persist, take the tool, battery pack and charger to your local service center.

4.The battery pack should be recharged when it fails to produce sufficient power on jobs which were easily done previously. DO NOT CONTINUE to use under these conditions. Follow the charging procedure. You may also charge a partially used pack whenever you desire with no adverse affect on the battery pack.

5.Foreign materials of a conductive nature such as, but not limited to, steel wool, aluminum foil, or any buildup of metallic particles should be kept away from charger cavities. Always unplug the charger from the power supply when there is no battery pack in the cavity. Unplug charger before attempting to clean.

6.Do not freeze or immerse charger in water or any other liquid.

WARNING: Shock hazard. Do not allow any liquid to get inside charger.

CAUTION: Never attempt to open the battery pack for any reason. If the plastic housing of the battery pack breaks or cracks, return to a service center for recycling.

TO MAXIMIZE BATTERY LIFE:

1.Remove the batteries from the charger after the charging is completed.

2.Store the batteries at room temperature or below.

3.Recharge discharged batteries within 1 week. Battery life will be greatly diminished if the battery sits too long after being discharged.

OPERATING INSTRUCTIONS

WARNING: Always use proper eye protection that conforms to ANSI Z87.1 (CAN/CSA Z94.3) while operating this power tool.

NOTE: Battery pack performance will decrease under heavy use conditions when temperature is below 32°F (0°C). As the battery cells heat up the performance will improve.

INSTALLING AND REMOVING THE BATTERY PACK (FIGURE D,E)

CAUTION: Make certain thelock-offbutton is engaged to prevent switch actuation before removing or installing battery.

Installing the battery pack:

Insert the metal terminal end of the battery pack into the product until you hear the lock snap into place and the VPXTM logo shows through the window as shown infigure D. CAUTION: The battery can only be inserted in one direction. If the battery does not fit,

remove and reverse the orientation. Do not force it.

Removing the battery pack:

Press the release button as shown in figure E and firmly pull the battery pack out of the handle. Insert the battery pack into the charger (figure B) as described in the charger section of this manual.

9

90520983 VPX1301 Cut SAW 7/19/07 3:03 PM Page 10

TRIGGER SWITCH (FIGURE F)

The tool is equipped with a switch lock-offfeature to prevent unintentional operation.

To operate the tool, slide the switch lock-offbutton (2) back and hold it as you pull the on/off switch (1).

After the tool is running, release the switch lock-offbutton. The tool will continue to run as long as the trigger is depressed.

To turn off, release the trigger switch. There is no provision for locking the tool on.

Hold saw firmly with one hand or both hands (figure H) while cutting. Whenever possible, the saw shoe must be held firmly against the material being cut. This will prevent the saw from jumping or vibrating and minimize blade breakage.

BLADE CLAMP RELEASE LEVER (FIGURE G)

The Black & Decker VPX1301 accepts both T-shankand universal shank jig saw blades. 1mm or thicker blade recommended.

CAUTION: Recently used blades may be hot.

To install blade into saw:

Push down on the blade clamp release lever to its full open position as shown in Figure G.

Insert blade shank from the front.

Release the blade clamp release lever.

To remove blade from saw:

Push down on the blade clamp release lever to its full open position.

Remove blade.

Release the blade clamp release lever.

WOOD CUTTING

WARNING: Use extra caution when cutting overhead and pay particular attention to overhead wires which may be hidden from view. Anticipate the path of falling branches and debris ahead of time.

WARNING: Inspect work site for hidden gas pipes, water pipes, or electrical wires before making blind or plunge cuts. Failure to do so may result in explosion, property damage, electric shock, and/or serious personal injury.

Before cutting any type of wood, 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.

Place shoe firmly against work to be cut.

Switch on saw motor before applying pressure.

Whenever possible, the shoe must be held firmly against the material being cut. This will prevent the saw from jumping or vibrating and minimize blade breakage.

METAL CUTTING (FIGURE H)

Use a finer blade for ferrous metals and a coarse blade for non-ferrousmaterials.

In thin gauge sheet metals it is best to clamp wood to both sides of sheet. This will ensure a clean cut without excess vibration or tearing of metal.

Avoid forcing cutting blade as this reduces blade life and causes costly blade breakage.

When cutting metal piping, do not cut directly through the pipe as you would saw a wooden dowel. Instead, cut around the circumference of the pipe to avoid pinching the blade. Only one section of the blade should be in contact with the pipe.

NOTE: You should spread a thin film of oil or other coolant along the line ahead of the saw cut for easier operation and longer blade life. For cutting aluminum, kerosene is preferred.

POCKET CUTTING - WOOD ONLY (FIGURE I)

Pocket cutting is used to cut a hole in a piece of material without cutting from the side.

Measure the surface area to be cut and mark clearly with a pencil.etc.

Tilt saw forward and rest front of the shoe on material to be cut.

Switch the tool on. Grip the handle firmly and raise the back edge of tool until the blade cuts smoothly into the material. Always be sure blade reaches its complete depth before starting to cut.

Allow the blade to come to a complete stop before lifting saw from material.

When starting each new cut, repeat the above steps.
