Work area safety
1. Keep work area clean and well lit. Cluttered or
dark areas invite accidents.
2. Do not operate power tools in explosive atmo-
VSKHUHVVXFKDVLQWKHSUHVHQFHRIÀDPPDEOH
liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.
3. Keep children and bystanders away while
operating a power tool. Distractions can cause
you to lose control.
Electrical Safety
1. 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. 8QPRGL¿HGSOXJVDQGPDWFKLQJRXWOHWVZLOO
reduce risk of electric shock.
2. Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges and
refrigerators.7KHUHLVDQLQFUHDVHGULVNRIHOHF-
tric shock if your body is earthed or grounded.
3. Do not expose power tools to rain or wet con-
ditions. Water entering a power tool will increase
the risk of electric shock.
4. 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.
5. 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.
6. If operating a power tool in a damp location is
unavoidable, use a ground fault circuit inter-
rupter (GFCI) protected supply. Use of a GFCI
reduces the risk of electric shock.
Personal Safety
1. 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

2. 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

3. 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

6. Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing, and gloves
away from moving parts./RRVHFORWKHVMHZHO-
lery or long hair can be caught in moving parts.

7. 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.
Power tool use and care
1. Do not force the power tool. Use the correct
power tool for your application.7KHFRUUHFW

be controlled with the switch is dangerous and
must be repaired.
3. 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 pre-
ventive safety measures reduce the risk of starting
the power tool accidentally.
4. Store idle power tools out of the reach of chil-
dren 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.
5. 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.
6. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
7. Use the power tool, accessories and tool bits
etc. in accordance with these instructions, tak-
ing 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.

Cordless recipro saw safety
warnings
1. Hold power tool by insulated gripping sur-
faces, when performing an operation where
the cutting accessory may contact hidden wir-
ing. 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 plat-
form. Holding the work by hand or against your
body leaves it unstable and may lead to loss of
control.
3. Always use safety glasses or goggles.
Ordinary eye or sun glasses are NOT safety
glasses.
4. Avoid cutting nails. Inspect workpiece for any
nails and remove them before operation.
5. Do not cut oversize workpiece.
6. Check for the proper clearance beyond the
workpiece before cutting so that the blade will
QRWVWULNHWKHÀRRUZRUNEHQFKHWF
7. +ROGWKHWRRO¿UPO\
8. Make sure the blade is not contacting the
workpiece before the switch is turned on.
9. Keep hands away from moving parts.
10. Do not leave the tool running. Operate the tool
only when hand-held.
11. Always switch off and wait for the blade to
come to a complete stop before removing the
blade from the workpiece.
12. Do not touch the blade or the workpiece imme-
diately after operation; they may be extremely
hot and could burn your skin.
13. Do not operate the tool at no-load
unnecessarily.
14. Always use the correct dust mask/respirator
for the material and application you are work-
ing with.
15. Some material contains chemicals which may
be toxic. Take caution to prevent dust inhala-
tion and skin contact. Follow material supplier
safety data.

Tips for maintaining maximum
battery life
1. Charge the battery cartridge before completely
discharged. Always stop tool operation and
charge the battery cartridge when you notice
less tool power.
2. Never recharge a fully charged battery car-
tridge. Overcharging shortens the battery
service life.
3. Charge the battery cartridge with room tem-
perature at 10 °C - 40 °C (50 °F - 104 °F). Let
a hot battery cartridge cool down before
charging it.
4. Charge the battery cartridge if you do not use
it for a long period (more than six months).

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:

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.
