General Safety Warnings
General power tool safety warnings
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.
• This product 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.
• Only use the product in the manner and
for the functions described in these
instructions.

4
Work area safety
• Keep the 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 adaptor plugs
with earthed (grounded) power tools.
Unmodified plugs and matching outlets
will reduce 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.

5
• 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 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.
• It is recommended that appliances
should be supplied via a residual
current device (RCD) with a tripping
current of not more than 30mA.
Personal safety
• 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.
• Use Personal Protective Equipment
(PPE). Always wear eye protection.
Protective equipment, such as a dust

6
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 a 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.
• 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 jewellery. Keep your hair, clothing and
gloves away from moving parts. Loose
clothes, jewellery or long hair can be caught
in moving parts.
• If devices are provided for the connection
of dust extraction and collection facilities,
ensure these are connected and properly
used. Use of a dust collection device can
reduce dust-related hazards.

7
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 safer 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 tools 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.

8
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 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.
• 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

9
immediately with water. If liquid contacts
the eyes, immediately seek medical help.
Liquid ejected from the battery may cause
irritation or burns.
Servicing
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.
