^GENERAL SETY RULES
A 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 0
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 medica¬
tion. 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 bal¬
ance 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 preventive 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 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.
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. Contact with a "live" wire will also 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.
Motor
Be sure your power supply agrees with nameplate marking. 120 Volts AC only means your
tool will operate on standard 60 Hz household power. Do not operate AC tools on DC. A rating
of 120 volts AC/DC means that your tool will operate on standard 60 Hz AC or DC power. This
information is printed on the nameplate. Lower voltage will cause loss of power and can
result in over-heating. All Black & Decker tools are factory-tested; if this tool does not operate,
check the power supply.
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
below.

INSTALLING BLADES (FIGURE 1)
BEFORE INSTALLING BLADES, TURN OFF AND UNPLUG TOOL
Loosen the two screws and ensuring that the blade teeth are facing forward, push the blade
shank as far as possible into the saw blade holder. Slightly tighten screws alternately to posi¬
tion the blade, then fully tighten screws. To release, turn both screws one turn counterclockwise.
ROLLER SUPPORT GUIDE (FIGURE 2)
The roller support guide on your jig saw improves its performance when cutting tough materi¬
als by adding support to the blade. This support should be adjusted so that the roller touches
the back of the blade when cutting.
To do this, loosen the clamp screw on the side of the tool. Push the blade support forward until
the roller touches the back edge of the blade, retighten the screw. Lubricating the guide roller
(4) from time to time with a drop of oil will extend the life of the roller.
OPERATING THE JIG SAW
To switch the jig saw on, fully squeeze the on/off trigger switch (1). To switch the jig saw off,
release the trigger switch (1). The tool can be locked on for continuous operation by squeezing
and holding the trigger switch while you depress the lock-on button (2). With the lock-on button
depressed, release the trigger switch and the tool will continue to run. To release from lock posi¬
tion, squeeze and release the trigger switch once.
Always disengage the the lock before disconnecting from the power supply.
BEWEL ADJUSTMENT (FIGURES 3 &4)
TURN OFF AND UNPLUG TOOL.
The shoe (5) can be angled up to 45° on either side. To do this, disconnect your jig saw from
the power supply. Raise the dust shroud (3) and loosen both screws on the shoe plate with a
screwdriver. Pull the shoe plate backward a little, and set the desired angular adjustment
according to the scale or push the shoe plate forward for fixed locks at 0°, 15°,30°,or 45°. Tighten
the screws to secure. Although the scale and notches are accurate for most purposes it is advis¬
able for very accurate angle cutting to use a protractor to set the shoe. Make a test cut on some
scrap material to check the accuracy of the angle. To reset the shoe for a square cut, loosen
the damp screws and move the shoe until it is approximately 90° to the blade, and then, while
applying slight forward pressure on the shoe, retighten the clamp screws.
