SAFETY INSTRUCTIONS
GENRAL SAFETY RULES
WARNING! Read all safety warnings and 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.
WORK AREA SAFETY
Keep work area clean and well lit. Cluttered or 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 children and bystanders away while operating a power tool.
Distractions can cause you to lose control.
ELECTRICAL SAFETY
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 the risk of electric
shock.
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.
Do not 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 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.
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.
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.
PERSONAL SAFETY
Stay alert, watch what you are doing and use common sense when
operating a power the tool. Do not use the 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.
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.

Prevent unintentional starting. Ensure that the switch is in the OFF-
position before connecting the tool to a power source and/or battery
pack, picking up or carrying the tool. Carrying power tools with your
finger on the switch or energizing power tools that have the switch on
invites accidents.
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.
Do not overreach. Keep proper footing and balance at all times. This
enables better control of the power tool in unexpected situations.
Dress properly. Do not wear loose clothing or jewelry. Keep your hair,
clothing and gloves away from moving parts. Loose clothes, jewelry or
long hair can be caught in moving parts.
If devices are provided for the connection of dust extraction and
collection facilities, ensure that these are connected and properly used.
Use of these devices can reduce dust-related hazards.
POWER TOOL USE AND CARE
Do not force the power tool. Use the correct power tool for your
application. The correct power tool will do the job better and more safely
at the rate for which it was designed.
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.
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.
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.
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.
Keep cutting tools sharp and clean. Properly maintained cutting tools with
sharp cutting edges are less likely to bind and are easier to control.
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.
BATTERY TOOL USE AND CARE
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.
Use power tools only with specifically designated battery packs. Use of
any other battery packs may create a risk of injury and fire.
Page 7
7
When the 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.
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.
SERVICE
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 FOR CORDLESS JIG SAW
Use only those batteries and the charger listed.
Battery pack Charger

252-8032
252-8036
Hold the power tool by its 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
workpiece to a stable platform. Holding the work by hand or against your
body leaves it unstable and may lead to loss of control.
When using the jigsaw, use safety equipment including safety goggles or
shield, ear protection, dust mask and protective clothing including safety
gloves.
Ensure that the lighting is adequate.
Do not use the saw unless the guards are in place.
Keep the shoe plate on the workpiece.
Do not put pressure on the saw, such that it slows the motor down. Allow
the saw blade to cut without pressure. You will get better results and you
will be taking better care of your tool.
Keep the area free of tripping hazards.
Do not let anyone under 18 years operate this jigsaw.
Only use blades in good condition.
Before cutting, check that there is sufficient clearance for the blade
under the workpiece.
Do not touch the blade after operation, it will be very hot.
Keep your hands away from under the workpiece.
Never use your hands to remove sawdust, chips or waste close to the
blade.
Page 8

Rags, cloths, cord, string and the like should never be left around the work
area.
Avoid cutting nails. Inspect the workpiece and remove all nails and other
foreign objects before beginning sawing.
Never reach over the blade to remove waste or off cuts.
Do not attempt to free a jammed blade before first switching off the
machine.
If you are interrupted when operating the saw, complete the process and
switch off before looking up.
Periodically check that all nuts, bolts and other fixings are properly
tightened.
Do not store materials or equipment above a machine in such a way that
they could fall into it.
Do not secure the jigsaw upside down in a vice or work bench and use it
as a saw bench. This can lead to serious injury.

trigger switch. To turn it OFF, release the trigger switch.
CAUTION! Allow the blade to come to a complete stop before setting the
jigsaw down.
VARIABLE SPEED TRIGGER SWITCH
(Fig. 3)
This tool has a variable speed switch
that delivers higher speed with
increased trigger pressure. Speed is
controlled by the amount of switch
trigger depression.
NOTE: Use the variable speed
feature for a short time only. Do not
continuously operate the tool at
different speeds. It may damage the
switch.
ELECTRIC BRAKE
To stop the jig saw, release the trigger switch and allow the tool to come to
a complete stop. The electric brake quickly stops the saw blade stroke. This
feature engages automatically when you release the trigger switch.

LED WORKLIGHT (Fig. 4)
The LED worklight, located above
the tool-less blade clamp, provides
additional lighting on the surface
of the workpiece for operation in
lower-light areas. The LED worklight
will come on automatically when the
trigger switch is depressed, and it
will turn off when the trigger switch is
released.
INSTALLING SAW BLADE (Fig. 5)
1. Remove the battery pack.
2. Turn the tool upside down and
press the blade clamp lever as
far as it can go; the lever will not
rebound back.
3. Insert the blade into the slot until it
locks into place automatically.
REMOVING SAW BLADE (Fig. 5)
CAUTION! Allow the blade to cool
after use. The blade can become dangerously hot.
1. Remove the battery pack.
2. Press down on the blade clamp lever to remove the blade.
3. The clamp stays open when the blade is removed; it automatically locks
when you push in another blade, providing for very easy one-hand blade
change.
BLADE SELECTION
To obtain the best performance from the saw, it is important to select the
correct blade for the particular application and type of material you wish to
cut. By doing this, you will get a smoother, faster cut and prolong blade life.
ORBIT ADJUSTMENT (Fig. 6)
The jigsaw has orbital action whereby
the blade roller guide moves back and
forth to make the blade swing slightly
as it cuts.
Orbital action increases the speed of
cut but may result in a rougher finish
to the cut in some materials.
Set the orbit control lever to one of the
four settings according to degree of
orbit action required:
0- No orbit action
1- Minimal orbit action
Fig. 5
Fig. 6
Fig. 4
LED worklight
Page 13
13
2- Medium orbit action
3- Maximum orbit action for the most aggressive action, for quick cutting
plywood or soft material.
Experiment on a piece of scrap material to determine the optimum orbit
action setting.
ADJUSTING THE SHOE FOR ANGULAR CUTTING (Fig. 7&Fig. 8)
CAUTION! Always ensure that the
jigsaw is switched off and the battery
pack is removed before making any adjustments.
1. Loosen the hex screw located on the
underside of the tool using hex key.
2. Move the shoe plate backwards
so that the teeth on the plate no
longer engage with the retaining
teeth and the shoe can be tilted to
the left or right.
3. Select 15°, 30° or 45° to the left
or right or select 0°, and push the
shoe plate forward so that the
teeth on the plate mesh with the
retaining teeth.
4. Retighten the hex screw.
The angle selected can be read on the
cutting angle guide on the shoe plate.
For accurate work it is necessary to
make a trial cut, then measure the
work and reset the angle with the
shoe plate moved a little towards the
rear so that the teeth on the plate do
not mesh with the retaining teeth.
Repeat the trial cut and reset the angle setting until the correct setting is
achieved.
PARALLEL GUIDE (Fig. 9)
The parallel guide fits into the shoe
plate and is locked in place by the
locking screw.
Use the parallel guide to guide the jigsaw
along a straight line which can be an
edge of a workpiece or a piece of straight
timber clamped to the workpiece.
By changing the position of the guide
and using the same straight edge as a
guide, it is possible to quickly and easily
make parallel cuts in the workpiece.
NOTE: When adjusting the cutting angle, you can move the parallel guide
locking screw to the left or right.

MAKING A CUT (Fig. 10)
1. Turn on the jigsaw and allow the
blade to reach maximum speed. Do
not allow the blade to contact the
workpiece until it has reached full
speed.
2. Slowly guide the jigsaw forward
using both hands, keeping the shoe
plate flat against the workpiece.
NOTE: Use only enough pressure to
keep the blade cutting. Do not force
the cutting; allow the blade and the
saw to do the work.
STRAIGHT CUTING
A straight cut can be made by
clamping a piece of wood or a straight edge to the workpiece and guiding
the edge of the saw against it. Make the cut from one direction only. NEVER
cut halfway and then complete the cut from the opposite end.
The straight cut can be also made by using the parallel guide supplied.
PLUNGE CUTTING (Fig. 11)
Plunge cutting is useful and timesaving for making rough openings in
soft materials. It makes it unnecessary
to drill a hole for an inside or pocket
cut.
1. Draw lines for the opening you
want to cut.
2. Hold saw firmly and tilt it forward
so the toe of the saw foot rests on
the workpiece.
3. Make sure that the blade is well
clear of the workpiece.
4. Start the saw and then gradually
lower the blade into the workpiece,
firmly holding the toe of the saw base to prevent side wobble.
5. Keeping the toe of the foot on the workpiece, slowly pivot the saw
downward like a hinge until the blade cuts through and the base rests flat
on the workpiece.
6. Begin sawing in the usual manner along the cut line.
