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-

2
English
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.
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.

3
English
• 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.
• Air vents often cover moving parts and should be avoided.
Loose clothes, jewelry or long hair can be caught in moving parts.
• An extension cord must have adequate wire size for safety.
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.
Voltage (Volts) Total length of cord in meters (m)
120–127V 0–7 7–15 15–30 30–50

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
• arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you
do this type of work. To reduce your exposure to these chemicals:

4
English
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.
WARNING: ALWAYS USE SAFETY GLASSES. Everyday
eyeglasses are NOT safety glasses. Also use face or dust mask if
cutting operation is dusty. ALL USERS AND BYSTANDERS MUST

connected to the power supply, it will start immediately. Damage to
your tool or personal injury may result.
This jig saw is equipped with FIG. 5
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.
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

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 FIG. 7
K
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.
When ripping, position as
J
FIG. 8
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.
