Specific Safety Rules and Symbols
Functional Description
Assembly
Operation
Maintenance
Accessories
!
ALWAYS WEAR EYE PROTECTION THAT CONFORMS WITH CSA
REQUIREMENTS or ANSI SAFETY STANDARD Z87.1
FLYING DEBRIS can cause permanent eye damage. Prescription
eyeglasses ARE NOT a replacement for proper eye protection.
WARNING: Non-compliant eyewear can cause serious injury if
broken during the operation of a power tool.
SAVE THESE INSTRUCTIONS FOR REFERENCE
WARNING: Use hearing protection, particularly during extended
periods of operation of the tool, or if the operation is noisy.
!
GENERAL SAFETY WARNINGS
CAUTION: Before using this tool or any of its accessories, read this
manual and follow all Safety Rules and Operating Instructions.
!

4
ELECTRICAL SAFETY
WARNING: To avoid electrical hazards, fire hazards or damage to the
tool, use proper circuit protection.
This tool is wired at the factory for 110–120 V operation. It must be
connected to a 110–120 V, 15 A circuit that is protected by a time-delayed
fuse or circuit breaker. To avoid shock or fire, replace power cord
immediately if it is worn, cut or damaged in any way.
GENERAL SAFETY WARNINGS
WEAR A DUST MASK THAT IS DESIGNED TO BE USED WHEN
OPERATING A POWER TOOL IN A DUSTY ENVIRONMENT.
WARNING: Dust that is created by power sanding, sawing, grinding,
drilling, and other construction activities may contain chemicals that are
known to cause cancer, birth defects, or other genetic abnormalities. These
chemicals include:
Lead from lead-based paints
Crystalline silica from bricks, cement, and other masonry products
Arsenic and chromium from chemically treated lumber
The level of risk from exposure to these chemicals varies, according to how
often this type of work is performed. In order to reduce exposure to these
chemicals, work in a well-ventilated area, and use approved safety
equipment, such as a dust mask that is specifically designed to filter out
microscopic particles.
!

5
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.
WORK AREA
Keep your work area clean and well lit.
Cluttered benches and dark areas invite
accidents.
Do not operate power tools in potentially
explosive environments, such as in the
presence of flammable liquids, gas or dust.
Power tools create sparks that may ignite
dust or fumes.
Keep bystanders, children and visitors
away while operating the tool. Distractions
can cause the operator to lose control.
ELECTRICAL SAFETY
Double insulated tools are equipped with a
polarized plug (one blade is wider than the
other). This plug will only fit into a
polarized plug one way.
If the plug does not fit into the outlet
properly, reverse the plug. If it still does not
fit, contact a qualified electrician to install a
polarized outlet. Do not alter the plug in
any way. Double insulation eliminates the
need for the three-pronged grounded
power cord and grounded power supply
system.
Avoid contact between the operator's body
and grounded surfaces such as pipes,
radiators, ranges, and refrigerators. There
is an increased risk of electric shock if the
operator's body is grounded.
Do not expose power tools to rain or wet
conditions. Water entering the power tool
will increase the risk of electric shock.
Do not abuse the cord. Do not use the
power cord to carry the tool or to pull the
plug out of the outlet. Keep the power cord
away from heat, oil, sharp edges, and
moving parts. Replace a damaged power
cord immediately. A damaged power cord
increases the risk of electric shock.
When operating a power tool outdoors,
use an outdoor-rated extension cord type
“W-A” or “W”. These cords are rated for
outdoor use and they reduce the risk of
electric shock.
PERSONAL SAFETY
Stay alert, be aware of the surroundings,
and use common sense when operating a
power tool. Do not use a power tool while
tired or under the influence of drugs,
alcohol, or medication. A moment of
inattention while operating a power tool
may result in serious personal injury.
Dress properly. Do not wear loose clothing
or jewellery.
Contain long hair. Keep hair, clothing, and
gloves away from moving parts. Loose
clothing, jewellery, or long hair can get
caught in moving parts.
!
POWER TOOL SAFETY

6
PERSONAL SAFETY –cont’d
Avoid accidental start-ups. Verify that the
switch is in the OFF position before
plugging in the tool. Carrying a power tool
with a finger on the switch or plugging in a
tool that has the switch in the ON position
invites accidents.
Remove adjusting keys and 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 allows the operator to maintain
better control of the tool in unexpected
situations.
Use safety equipment. Always wear eye
protection.
Use a dust mask, non-skid safety shoes, a
hardhat, or hearing protection when
appropriate.
USE AND CARE OF POWER TOOLS
Use clamps or another practical means to
secure and support the workpiece to a
stable platform. Holding the work in a hand
or against the body is not stable, and may
lead to loss of control.
Do not force the tool. Use the correct tool
for the application. The correct tool will do
the job better and safer when used at the
rate that it was designed to work at.
Do not use a power tool if it cannot be
turned ON or OFF using the power switch.
A tool that cannot be controlled using the
switch is dangerous, and must be repaired.
Disconnect the plug from the outlet before
making any adjustments, changing
accessories, or storing the tool. Such
preventive safety measures reduce the risk
of accidental start-ups.
When power tools are not in use, store
them out of the reach of children or
untrained persons. Tools are dangerous in
the hands of untrained users.
Maintain tools with care. Keep cutting tools
sharp and clean. Properly maintained
cutting tools with sharp cutting edges are
less likely to bind, and are easier to
control.
Inspect the tool for misalignment or binding
of moving parts, broken parts, and any
other condition that may affect the
operation of the tool. If it is damaged, have
the tool serviced before using it. Many
accidents are caused by poorly maintained
tools.
Use only accessories that are
recommended by the manufacturer for this
model. Accessories that are suitable for
one tool may become hazardous when
used with another tool.
SERVICE
Tool servicing must be performed by
qualified personnel. Service or
maintenance performed by non-qualified
personnel could result in a risk of injury.
POWER TOOL SAFETY

7
SERVICE –cont’d
When servicing a tool, use only identical
replacement parts. Follow the instructions
in the Maintenance section of this Manual.
The use of unauthorized parts or failure to
follow the instructions in the Maintenance
section of this Manual may create a risk of
electric shock or injury.
WARNING: Know your cordless
jigsaw. Do not plug in the charger or
install the battery in the tool until you
have read and understand this
Instruction Manual. Learn the tool’s
applications and limitations, as well as
the specific potential hazards related to
this tool. Following this rule will reduce the
risk of electric shock, fire, or serious injury.
Always wear eye protection. Any power
tool can throw foreign objects
into your eyes and cause
permanent eye damage.
ALWAYS wear safety goggles
(not glasses) that comply with ANSI safety
standard Z87.1. Everyday glasses have
only impact resistant lenses. They ARE
NOT safety glasses.
WARNING: Glasses or goggles
not in compliance with ANSI Z87.1
could cause serious injury when they
break.
Always wear safety goggles, hearing
protection and a dust mask. Use only in
well-ventilated areas. Using personal
safety devices and working in a safe
environment reduces the risk of injury.
Hold the tool by insulated gripping
surfaces when performing an operation
where the saw blade 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.
Always make sure the work surface is free
of nails and other foreign objects. Cutting
into a nail can cause the blade and the tool
to jump and damage the blade.
Never hold the workpiece in one hand and
the tool in the other hand when sawing.
Never place your hands near or below the
cutting surface. Clamping the material and
guiding the tool with both hands is much
safer.
Never lay the workpiece on hard surfaces
like concrete, stone, etc. The protruding
blade may cause the tool to jump.
DANGER: Always remove the
battery when changing the blade and when
making adjustments.
Use only U- or T- shank blades that are
designed specifically for jigsaw use. Never
use a broken blade, as it will not be
securely held in the tool.
SPECIFIC SAFETY
RULES

POWER TOOL SAFETY

8
After changing a blade, make sure the
blade is securely held in the blade holder.
Loose blades will be violently thrown.
Never touch the blade during or
immediately after use. After use, the blade
is too hot to be touched by bare hands.
Never use dull or damaged blades. Sharp
blades must be handled with care.
Damaged blades can snap during use.
Dull blades require more force to cut the
workpiece, possibly causing the blade to
break.
Always use the straight reciprocating
action when cutting metal. Blades will last
longer and will be less likely to break.
Battery packs and chargers must be
purchased separately.

19
GENERAL CUTTING –cont’d
WARNING: Keep hands and
fingers away from between the motor
housing and blade holder. Do not reach
underneath workpiece while jigsaw is
running.
3. Rest the front of the jigsaw base on
the workpiece and align cutting edge
of the blade with the cutting line on
your workpiece (Fig. 12). Make sure
the power cord is out of your way and
not in the path the blade will follow.
4. While firmly gripping the jigsaw, and
with the blade NOT in contact with the
surface to be cut, start the jigsaw by
pressing the lock-off button and
squeezing the trigger switch.
5. Once the jigsaw has reached the
desired speed, gradually bring the
moving blade into contact with the
workpiece at the appropriate location.
NOTE: Apply enough downward pressure
to keep the jigsaw steady and only enough
forward pressure to keep the blade cutting
freely.
CAUTION: Do not force the
jigsaw. Use only enough force to keep
the blade cutting. Excessive pressure
on the blade will cause it to bend and
twist, which may result in breaking the
blade.

BEVEL CUTTING - cont’d
Once the cutting angle has been verified,
proceed with the cutting activity as outlined
in “GENERAL CUTTING” above.
PLUNGE CUTTING
WARNING: To avoid loss of
control, broken blades or damage to the
workpiece, always use extreme caution
when making plunge cuts. It is not
recommended to plunge cut any
material other than wood. Wherever
possible, drill a pilot hole 3/8" (9.5 mm)
or larger in the area to be cut out and
start cutting with the blade in the pilot
hole. This will avoid the need to plunge
cut.
NOTE: Use only blades with 7 teeth per
inch for plunge cutting.
1. To plunge cut an inside hole, clearly
mark the cutting line on the workpiece.
2. Set the bevel angle at 0°, and then
lock the base plate.
3. Tilt the jigsaw forward so it rests on
the front edge of the base plate and in
a position where the blade will NOT
touch the workpiece when the switch
is turned ON (Fig. 13).
NOTE: Make sure the saw blade is inside
the area to be cut.
4. Start the jigsaw and slowly lower the
blade onto the workpiece while
making sure the front of the saw base
remains in contact with the workpiece.
Allow the blade to slowly cut through
the wood.
