General Power Tool Safety Warnings
WARNING! Read all safety warnings and all instructions
Failure to follow the warnings and instructions may result in
electric shock, fire and/or serious injury.
SAVE ALL WARNINGS AND INSTRUCTIONS
FOR FUTURE REFERENCE
The term “power tool”in the warnings refers to your mains-operated
(corded) power tool or battery-operated (cordless) power tool.
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.
f) If operating a power tool in a damp location is unavoidable,
use a residual current device (RCD) protected supply.
Use of an RCD 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 tools may result in serious personal injury.
b) Use personal protective equipment. Always wear eye
protection. Protective equipment such as dust mask, non-
English
1
skid safety shoes, hard hat, or hearing protection used for
appropriate conditions will reduce personal injuries.
c) Prevent unintentional starting. Ensure the switch is in
the off position before connecting to power source and/
or battery pack, picking up or carrying the tool. Carrying
power tools with your finger on the switch or energising power
tools that have the switch on invites accidents.
English
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 jewellery.
Keep your hair, clothing and gloves away from moving
parts. Loose clothes, jewellery or long hair can be caught in
moving parts.
g) If devices are provided for the connection of dust
extraction and collection facilities, ensure these are
connected and properly used. Use of dust collection 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.
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 tool’s 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 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) 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
Safety Warnings for Jig Saws
• Hold power tools 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 another practical way to secure and
support the work piece to a stable platform. Holding the
work by hand or against your body leaves it unstable and
may lead to loss of control.
2
• 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.
• When cutting pipe or conduit ensure that they are free
from water, electrical wiring, etc.
• Allow the motor to come to a complete stop before
withdrawing the blade from the kerf (the slot created by
cutting). A moving blade may impact the workpiece causing
a broken blade, workpiece damage or loss of control and
possible personal injury.
• Never hold work in your hand, lap or against parts of
your body when sawing. The saw may slip and the blade
could contact the body causing injury.
• Keep handles dry, clean, free from oil and grease. This
will enable better control of the tool.
• Clean out your tool often, especially after heavy use.
Dust and grit containing metal particles often accumulate on
interior surfaces and could create an electric shock hazard.
• Do not operate this tool for long periods of time. Vibration
caused by the operating action of this tool may cause
permanent injury to fingers, hands, and arms. Use gloves to
provide extra cushion, take frequent rest periods, and limit
daily time of use.
• 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: Wear appropriate hearing protection during use.
Under some conditions and duration of use, noise from this product
may contribute to hearing loss.
• 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. An undersized
cord will cause a drop in line voltage resulting in loss of power
and overheating. When using more than one extension to make
up the total length, be sure each individual extension contains
at least the minimum wire size. 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.

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
products, and
English
• 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.
WARNING: Use of this tool can generate and/or disburse 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.

Cutting Action –
Orbital or Straight
(Fig. 5)
WARNING: Check that the tool is not locked ON before
connecting it to a power supply. If the trigger switch is locked on
when the tool is connected to the power supply, it will start
immediately. Damage to your tool or personal injury may result.
This jig saw is equipped with
four cutting actions, three orbital
and one straight. Orbital action
has a more aggressive blade
motion and is designed for cutting
in soft materials like wood or
plastic. Orbital action provides a
faster cut, but with a less smooth
cut across the material. In orbital
action, the blade moves forward during the cutting stroke in addition
to the up and down motion.
FIG. 5
NOTE: Metal or hardwoods should never be cut in orbital action.
TO ADJUST THE CUTTING ACTION
1. Move the cutting action lever (I) between the four cutting
positions: 0, 1, 2, and 3.
2. Position 0 is straight cutting.
3. Positions 1, 2, and 3 are orbital cutting.
The aggressiveness of the cut increases as the lever is adjusted
from one to three, with three being the most aggressive cut.
LED Light
The jig saw is equipped with a light which projects on the cutting
path.
The light will come on when the trigger switch is depressed and will
go off when the trigger switch is released.
Removable Shoe Sleeve (Fig. 6)
The non-marring shoe sleeve (E) should be used when cutting
surfaces that scratch easily, such as laminate, veneer, or paint. It
can also be used to protect the shoe surface during transportation
and storage.
To attach shoe sleeve, place

Hints for Optimum Use
SAWING LAMINATES
As the saw blade cuts on the upward stroke, splintering may occur
on the surface closest to the shoe plate.
– Use a fine-tooth saw blade.
– Saw from the back surface of the workpiece.
– To minimize splintering, clamp a piece of scrap wood or
hardboard to both sides of the workpiece and saw through this
sandwich.
SAWING METAL
– Be aware that sawing metal takes much more time than sawing
wood.
– Use a saw blade suitable for sawing metal.
– When cutting thin metal, clamp a piece of scrap wood to the
back surface of the workpiece and cut through this sandwich.
– Spread a film of oil along the intended line of cut for easier
operation and longer blade life. For cutting aluminum, kerosene
is preferred.
Rip/Circle Cutting (Fig. 7, 8)
Ripping and circle cutting
without a pencil line are
easily done with the rip
fence / circle guide (not
included; available at extra
cost).
Using the screw supplied
with the accessory guide,
position as shown in
Figure 7 and thread the
screw into the shoe to clamp
the fence securely.
FIG. 7
K
When ripping, position as
shown in Figure 7 and slide
the rip fence under the
screw from either side of the
saw. Set the cross bar (J) at
desired distance from blade
and tighten screw. For
ripping, the cross bar should
be down and against the
straight edge of the
workpiece as shown.
When circle cutting, adjust
rip fence so that distance
from blade to hole in fence
arm (K) is at the desired radius and tighten screw. Place saw so
that hole in fence arm is over center of circle to be cut (drill hole for
blade or cut inward from edge of material to get blade into position).
When saw is properly positioned, drive a small nail through hole in
fence arm. Using rip fence as a pivot arm, begin cutting circle. For
circle cutting, the cross bar should be up, as shown in Figure 8.
