NOTE: The declared vibration emission value has
been measured in accordance with the standard test
method and may be used for comparing one tool with
another.
NOTE: The declared vibration emission value
may also be used in a preliminary assessment of
exposure.
WARNING: The vibration emission during actual
use of the power tool can differ from the declared
emission value depending on the ways in which the
tool is used.
WARNING: Be sure to identify safety measures
to protect the operator that are based on an estima-
tion of exposure in the actual conditions of use (taking
account of all parts of the operating cycle such as
the times when the tool is switched off and when it is
running idle in addition to the trigger time).

all instructions. Failure to follow the warnings and
Save all warnings and instruc-
tions 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
1. Keep work area clean and well lit. Cluttered or
dark areas invite accidents.
2. Do not operate power tools in explosive atmo-
liquids, gases or dust.
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

modify the plug in any way. Do not use any
adapter plugs with earthed (grounded) power
tools.

2. Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of elec-
tric shock if your body is earthed or grounded.

ditions.
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.
a cord suitable for outdoor use reduces the risk of
electric shock.

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
that have the switch on invites accidents.
4. Remove any adjusting key or wrench before

balance at all times. This enables better control
of the power tool in unexpected situations.
6. Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing, and gloves
away from moving parts.-
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.
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. The correct
rate for which it was designed.
2. Do not use the power tool if the switch does
not turn it on and off.

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.
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.
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

warnings
1. Hold power tool by insulated gripping sur-
faces, when performing an operation where
the fastener may contact hidden wiring.
Fasteners contacting a "live" wire may make
exposed metal parts of the power tool "live" and
could give the operator an electric shock.

4. Wear ear protectors.
5. Do not touch the bit or the workpiece immedi-
ately after operation. They may be extremely
hot and could burn your skin.
6. Keep hands away from rotating parts.

Important safety instructions for
battery cartridge
1.
Before using battery cartridge, read all instruc-
tions and cautionary markings on (1) battery
charger, (2) battery, and (3) product using battery.
2. Do not disassemble battery cartridge.
3. If operating time has become excessively
shorter, stop operating immediately. It may
result in a risk of overheating, possible burns
and even an explosion.
4.
If electrolyte gets into your eyes, rinse them out
with clear water and seek medical attention right
away. It may result in loss of your eyesight.
5. Do not short the battery cartridge:
(1) Do not touch the terminals with any con-
ductive material.
(2) Avoid storing battery cartridge in a con-
tainer with other metal objects such as
nails, coins, etc.
(3) Do not expose battery cartridge to water
or rain.
A battery short can cause a large current
breakdown.
6. Do not store the tool and battery cartridge in
locations where the temperature may reach or
exceed 50 °C (122 °F).
7. Do not incinerate the battery cartridge even if
it is severely damaged or is completely worn
8. Be careful not to drop or strike battery.
Do not use a damaged battery.
10.
The contained lithium-ion batteries are subject to
the Dangerous Goods Legislation requirements.
For commercial transports e.g. by third parties,
forwarding agents, special requirement on pack-
aging and labeling must be observed.
For preparation of the item being shipped, consult-
ing an expert for hazardous material is required.
national regulations.
Tape or mask off open contacts and pack up the
battery in such a manner that it cannot move
around in the packaging.

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).
