prevent damage to the battery pack.
› Do not incinerate the battery pack
even if it is seriously damaged or is
completely worn out. The battery can
explode in a fire.
› Never attempt to open the battery
pack for any reason. If the plastic
housing of the battery pack breaks or
cracks, immediately discontinue use
and do not recharge.
Save these instructions and other
documents supplied with this tool for
future reference.
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
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.
!

4
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.
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

5
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.
b) If the supply cord is damaged,
it must be replaced by the
manufacturer, its service agent or
similarly qualified persons in order to
avoid a hazard.
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. Use
of any other battery packs may create
a risk of injury and fire.
c) When the battery 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.

ADDITIONAL SAFETY FOR
RECIPROCATING SAWS
a) Hold power tool 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
This appliance is not intended for
use by persons (including children)
with reduced physical, sensory
or mental capabilities, or lack of
experience and knowledge, unless
they have been given supervision or
instruction concerning use of the
appliance by a person responsible for
their safety.
Recommendations for the use of a
residual current device with a rated
residual current of 30mA or less:
› Wear a hard hat (safety helmet),
safety glasses and/or face shield. It
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.
is also highly recommended that you
wear a dust mask, ear protection and
padded gloves.
› Hold the power tool with a firm grip.
› Secure the work piece. A work piece
clamped with clamping devices or
in a vice, is held more secure than
by hand.
› One-handed operation can be
hazardous. It is recommended you
hold the unit firmly with both hands
when operating the tool.
› After installing a blade, pull lightly on
it to make sure that it does not come
loose. If the blade is not installed
properly, it can come loose during
use, which can be dangerous.
› Use a blade that is appropriate for the
application.
› Check that any blade to be used
is not cracked or broken. Broken or
cracked blades are dangerous.
› If the screw securing the blade is
damaged, the blade may come off
during use causing personal injury.
› The torque delivered by the
reciprocating saw depends on how
long it is applied and other factors
such as the state of the battery charge.
› Stop the reciprocating saw before
changing the direction. Always
release the trigger and wait for the
reciprocating saw to stop before
switching the direction of rotation.
› Never touch the blade whilst it is in
use. Do not let the blade get near your

LITHIUM-ION BATTERY &
CHARGER SAFETY
OVER CHARGING PROTECTION
This feature ensures that the battery is
never overcharged. When the battery
has reached its full charge capacity
the charger will shut off protecting the
internal components of the battery
from being damaged.
OVER DISCHARGE PROTECTION
An internal component of the
battery pack is an over discharge
protector. This feature will stop the
battery from discharging beyond the
recommended lowest safety voltage.
OVER HEAT PROTECTION
The battery has an internal Thermister
cut off sensor which will cease the
charging cycle if the battery becomes
hot during the charging process. This
Thermister sensor will also stop the
battery from operating should the
battery become too hot during the
operation of the tool. This can happen
when the tool is overloaded or being
used for extended periods of time.
Up to 30min in cooling time may
be required depending on ambient
temperature and operation being
performed.
OVER CURRENT PROTECTION
Should the battery be overloaded
and the maximum current draw be
exceeded the battery will temporarily
stop working to protect the internal
components. The battery will resume
to normal operation once the
excessive current draw has returned
to normal safe level. This may take a
few seconds.
SHORT CIRCUIT PROTECTION
If the battery pack was to short circuit
the short circuit protector would
immediately stop the battery pack
from operating. This will ensure that
no further internal components of the
battery or the tools are damaged.
as you could be cut.
› Do not touch the blade after it has
been in use for an extended period. It
could be hot and burn you.
