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 chemical: 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 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-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

6EN
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.
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) SERVICE

Your switch is locked off to prevent accidental starting.
Depress lock-off button then on/off switch and release lock-
off button. Your switch is now on. To switch off just release
the on/off switch.
2. VARIABLE SPEED CONTROL (SEE FIG. G)
The on/off switch is also a variable speed controlled trigger
switch. the blade plunger stroke rate can be adjusted from
the minimum to maximum by the pressure you apply to the
on/off switch.
Apply more pressure to increase the speed and release

11
EN
pressure to decrease speed.
3. HAND GRIP AREAS (SEE FIG. H)
Always hold your saw firmly with both hands when
operating.
4. PLUNGE CUTTING (SEE FIG. I)
WARNING! The plunge cutting procedure is
only suitable for treating soft materials such
as wood, plaster board or similar! Do not work
metal materials with the plunge cutting procedure!
Use only short saw blades for plunge cutting.
Place the machine with the edge of the blade foot onto
the workpiece and switch on. For power tools with
stroke speed control, set the maximum stroke speed.
Press the power tool firmly against the workpiece and
allow the saw blade to slowly plunge into the workpiece.
As soon as the blade foot fully lays on the surface of
the workpiece, continue sawing alongside the desired
cutting line. For certain work, the saw blade can also be
inserted turned through by 180° and the sabre saw can
be guided accordingly in a reversed manner.
5. FLUSH CUTTING (SEE FIG. J1, J2)
WARNING! Pay attention that the saw blade
always extends beyond the diameter of the
material being worked. There is danger of kickback.
It is possible to make cuts extremely close to floors, walls
and other difficult areas. Insert the blade shank into the
blade clamp with the blade teeth facing up (opposite to
normal working position). This will make cuts closer to
the work surface. Using special flexible blades insert the
blade into the blade clamp with the blade teeth facing down
(normal working position). It will allow flush pipe cutting.
6. WOOD CUTTING
Always ensure the work-piece is firmly clamped to prevent
movement. For easier control use low speed to start cutting,
then increase to correct speed.
7. METAL CUTTING
This saw has different metal cutting capacities depending
upon the type of blade being used and metal being cut.
ALWAYS clamp the work down to prevent it from slipping.
Use a finer blade for ferrous metals and a coarse blade for
non-ferrous metals.
When cutting thin gauge sheet metals, ALWAYS clamp
wood on both sides of the sheet. This will give you a clean
cut without excess vibration or tearing of the metal.
DO NOT force the cutting blade. Forcing the blade will
reduce blade life and cause the blade to break.
NOTE: We recommend that you spread a thin film of oil or
other coolant along the line of cut ahead of the saw. This
will allow easier operation and help extend blade life. When
cutting aluminum, use kerosene.
8. POCKET CUTTING (SOFT MATERIALS ONLY. DO
NOT PLUNGE CUT IN METAL SURFACES.) (SEE FIG. K)
Mark the pocket or internal hole to be cut out. Insert the
special cutting blade with blade teeth facing down and
clamp securely. Angle the saw so that the back edge of
the blade guard is resting on the work surface. Use a
slow speed to start the cut to avoid breaking the blade but
increase to correct speed once the cut has started. With
the blade guard held firmly against the work surface, start
a slow but controlled upward swing of the saw. The blade
will cut into and through the material. Always ensure the
blade is completely through the material before cutting the
remainder of the pocket.
WORKING HINTS FOR YOUR CORDLESS
RECIPROCATING SAW
If your power tool becomes too hot, set the speed to
maximum and run no load for 2-3 minutes to cool the motor.
Always ensure the work-piece is firmly held or clamped to
prevent movement.
The pivoting foot must be held firmly against the material
being cut to reduce saw vibration, blade jumping and blade
breakage.
MAINTAINACE
Remove the battery pack from the tool before carrying
out any adjustment, servicing or maintenance.
Your power tool requires no additional lubrication 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 0oC (44.6oF) - 45oC (113oF).
The recommended ambient temperature range for the
charging system during charging is 0oC (44.6oF)-40oC
(104oF).
