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 visi-

tors away while operating a power
tool. Distractions can cause you to

lose control.

Electrical Safety

✔ Grounded tools must be plugged

into an outlet properly installed and
grounded in accordance with all
codes and ordinances. Never
remove the grounding prong or
modify the plug in any way. Do not
use any adaptor plugs. Check with
a qualified electrician if you are in
doubt as to whether the outlet is
properly grounded. If the tools

should electrically malfunction or
break down, grounding provides a low
resistance path to carry electricity
away from the user. Applicable only to
Class I (Grounded) tools.

✔ 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. Applicable only
to Class ll tools.

✔ 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 out-

side, 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

GENERAL SAFETY RULES

IMPORTANT! READ ALL INSTRUCTIONS!

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 wrench-

es 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, 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 chil-

dren and other untrained persons.

Tools are dangerous in the hands of
untrained users.

✔ Maintain tools with care. Keep cut-

ting 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 rec-

ommended 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 unau-

thorized parts or failure to follow
Maintenance Instructions may create
a risk of electric shock or injury.

Specific Safety Rules

✔ Hold tool by insulated gripping sur-

faces 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.

• KEEP HANDS AWAYfrom cutting
area. Never reach underneath the
material for any reason.

• KEEP BLADES SHARP . Dull blades
may cause the saw to swerve or stall
under pressure.

EXTENSION CORDS

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
gauge. The smaller the gauge number,
the heavier the cord

MOTOR

Be sure your power supply agrees with
nameplate marking. 120 Volts AC only
means your drill will operate on standard
60 Hz household power. Do not operate
AC tools on DC. Arating 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 over­heating. All BENCHTOP®tools are
factory-tested; if this tool does not

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 prod
ucts, 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..

the blade, lift the lever.

ROLLER SUPPORT GUIDE

The roller support guide on your jig saw
improves its performance when cutting
tough materials by adding support to the
blade. This support should be adjusted
so that the roller touches the back of the
blade when cutting. Ensure the blade is
aligned with the groove in the roller.
Adjust the support roller by loosening
the screw on the bottom of the shoe
(Fig.2) and moving the shoe so that the
roller touches the back edge of the
blade. Retighten screw. Lubricating the
guide roller from time to time with a drop
of oil will extend the life of the roller.
