PRODUCT SAFETY
WARNING: Some dust created by power sanding,
sawing, grinding, drilling and other construction
activities contains chemicals known to the State of California
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;
•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: 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.
WARNING: This product can expose you to
chemicals including lead and Di(2-ethylhexyl)
phthalate (DEHP) which are known to the State of California
to cause cancer and birth defects or other reproductive
harm. For more information go to www.P65Warnings.ca.gov.
GENERAL POWER TOOL SAFETY WARNINGS
WARNING: Read all safety warnings,
instructions, illustrations and specifications
provided with this power tool. Failure to follow all
instructions listed below 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 electric
(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-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 and clothing 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

6EN
connected and properly used. Use of dust collection
can reduce dust-related hazards.
h) Do not let familiarity gained from frequent use of
tools allow you to become complacent and ignore
tool safety principles. A careless action can cause
severe injury within a fraction of a second.
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 remove the battery pack, if detachable, 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 and accessories. 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.
h) Keep handles and grasping surfaces dry, clean
and free from oil and grease. Slippery handles and
grasping surfaces do not allow for safe handling and
control of the tool in unexpected situations.
5) Battery tool use and care
a) Recharge only with the charger specified by the
manufacturer. A charger that is suitable for one type
of battery pack may create a risk of fire when used with
another battery pack.
b) Use power tools only with specifically designated
battery packs. Use of any other battery packs may
create a risk of injury and fire.
c) When battery pack is not in use, keep it away from
other metal objects, like paper clips, coins, keys,
nails, screws or other small metal objects, that can
make a connection from one terminal to another.
Shorting the battery terminals together may cause burns
or a fire.
d) Under abusive conditions, liquid may be ejected
from the battery; avoid contact. If contact
accidentally occurs, flush with water. If liquid
contacts eyes, additionally seek medical help.
Liquid ejected from the battery may cause irritation or
burns.
e) Do not use a battery pack or tool that is damaged or
modified. Damaged or modified batteries may exhibit
unpredictable behaviour resulting in fire, explosion or
risk of injury.
f) Do not expose a battery pack or tool to fire
or excessive temperature. Exposure to fire or
temperature above 130 °C may cause explosion.
g) Follow all charging instructions and do not charge
the battery pack or tool outside the temperature
range specified in the instructions. Charging
improperly or at temperatures outside the specified
range may damage the battery and increase the risk
of fire.
6) Battery tool use and care
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.
b) Never service damaged battery packs. Service
of battery packs should only be performed by the
manufacturer or authorized service providers.
JIG SAW SAFETY WARNINGS
1. Hold Jig saw by insulated gripping surfaces,
when performing an operation where the cutting
accessory may contact hidden wiring. Cutting
accessory contacting a “live” wire may make exposed
metal parts of the power tool “live” and could give the
operator an electric shock.
2. Use clamps or another practical way to secure and
support the workpiece to a stable platform. Holding
the workpiece by hand or against your body leaves it
unstable and may lead to loss of control.

3. HAND GRIP AREAS
Always ensure you maintain a firm grip whilst operating
your jigsaw.
4. ALLEN KEY STORAGE (SEE FIG. C)
The allen key is placed at the position as shown.
5.BLADE FITTING
NOTE: Remove the plug from the socket
before carrying out any adjustment, servicing or
maintenance. Wear protective gloves when assembling the

10 EN
saw blade (11). You can only use the blade type shown in
Fig E1. Don’t use other blade types.
Inserting the saw blade
To open the blade holder (13) rotate the blade holder ring
anti-clockwise (Jigsaw upside down) and hold in position.
Then fully insert the blade (11) into the blade holder slot with
blade teeth facing forward and release the ring, which will
self rotate and clamp over the top of the blade (See Fig E2).
Push the blade into the blade holder again to ensure it is
locked in position. Ensure the edge of the blade is located in
the groove of the blade guide (See Fig E3).
Removing the saw blade
To remove a blade, hold the blade and rotate the blade
holder ring anti-clockwise then lift out the blade (blade
could be spring ejected) (See Fig E4).
WARNING: Blade teeth are very sharp. For best
cutting results ensure you use a blade
suited to the material and cut quality you need.
6. PENDULUM ACTION CONTROL
The pendulum action varies the forward
cutting angle of the blade for increased cutting efficiency.
This can also be adjusted during no load running. Refer to
the chart 2 for more details. Do not use excessive blade
force when cutting with the pendulum action. The blade
cuts on the upward stroke only (See Fig. F).

IHard materials, (e.g. steel & chipboard)
II Thick materials ( e.g. wood ) & plastic
III Fast cuts (e.g. softwood).
Cutting in the direction of the wood
grain.
7. BASE PLATE ANGLE ADJUSTMENT
Use an Allen key (5). Loosen the bolts securing the base
plate (See Fig G1). For preset angles rotate so the lines of
the angle on the base plate and angle plate (8) superposition
at the desired angle (0°, 15°, 30°, 45°) (See Fig G2). For
other mitre angles, rotate to your desired angle (use a
protractor scale). Following one of the above procedures,
hold the base plate in position and firmly tighten the bolts to
clamp the base plate at that angle. Finally, check the angle
and ensure the base plate is firmly clamped. The angle
markings on the base plate are accurate for most general
purposes but it is recommended for accurate work to set
the angle with a protractor and make a test cut on other
material.
8. VACUUM ADAPTOR
Mount the dust vacuum adaptor (4) into the opening of the
base plate (6). Make sure that the plastic tip of the vacuum
connection engages into the corresponding opening on the
housing as shown in the figure (See Fig H1).
Remove the dust vacuum adaptor (4) as shown in the figure
(See Fig H2).
WORKING HINTS FOR YOUR JIGSAW
If your jig saw becomes too hot, especially when used at
low speed, set the speed to maximum and run no Load for
2-3 minutes to cool the motor. Avoid prolonged usage at
very low speeds.
GENERAL
Always use a blade suited to the material and material
thickness to be cut. Always ensure the work–piece is firmly
held or clamped to prevent movement. For easier control,
use low speed to start cutting, then increase to correct
speed.
Any movement of the material may affect the quality of the
cut. The blade cuts on the upward stroke and may chip the
uppermost surface or face of the work piece. Ensure your
uppermost surface is a non-visible surface when your work
is finished.
1. CUTTING LAMINATES
Use a fine tooth blade when cutting most laminates and thin
wood materials. To reduce edge chipping, clamp pieces of
waste wood at both ends on both sides and cut through the
waste wood during cutting.
2. CIRCLE CUTTING
Do not use the pendulum action when cutting tight circles
or angles.
3. PLUNGE SAWING (See Fig. I1, I2)
Plunge cutting may be used only on soft materials such as
wood, aerated concrete, gypsum plaster boards, etc.
Use only short saw blades.
Place the front edge of the base plate on the workpiece and
switch on. Press the tool firmly against the workpiece and
plunge the saw blade slowly into the workpiece.
As soon as the complete surface of the base plate rests on
the work piece, continue to saw along the cutting line.
4. METAL CUTTING
Use a finer tooth blade for ferrous metals and a coarse tooth
blade for non-ferrous metals.
When cutting thin sheet metals, always clamp wood on
both sides of the sheet to reduce vibration or tearing of the
sheet metal. Both wood and sheet metal must be cut. Do

11
EN
not force the cutting blade when cutting thin metal or sheet
steel, as they are harder materials and will take longer to
cut. Excessive blade force may reduce the life of the blade or
damage the motor. To reduce heat during metal cutting, add
a little lubricant along the cutting line.
MAINTENANCE
Remove the battery pack from the tool before carrying
out any adjustment, servicing or maintenance.
There are no user serviceable parts in your power tool.
Never use water or chemical cleaners to clean your power
tool. Wipe clean with a dry cloth. Always store your power
tool in a dry place. Keep the motor ventilation slots clean.
Keep all working controls free of dust. Occasionally you may
see sparks through the ventilation slots. This is normal and
will not damage your power tool.
For Battery tools
The ambient temperature range for the use and storage of
tool and battery is 0 oC (44.6 oF)-45oC (113 oF).
The recommended ambient temperature range for the
