2. GENERAL POWER TOOL SAFETY WARNINGS
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.
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,
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 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) 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.
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.

6. BATTERY PACK AND BATTERY CHARGER
Safety
Correct handing of battery pack and battery chargers
Ensure that the power tool is switched OFF before you insert the battery
pack. Inserting a battery pack into a power tool that is the switch can be
locked in on position can cause accidents.
Charging battery pack only with the chargers recommended by the
manufacturer.
Charging the battery pack in another type of charger can lead to injury or
fire.
Only use the battery pack with the power tools, The use of other batteries
can lead to injury or fire.
Keep unused batteries away from staples, coins, keys, nails, screws or
other metal objects that could bridge the contacts on the battery pack. A
short circuit between the battery pack contacts can lead to burns or fire.
Fluid can leak from the battery pack if the power tool or the battery pack
is used incorrectly. Avoid contact with any fluid which may leak from the
battery pack. Wash your skin with water should you come into contact
with the fluid. Should the fluid come into contact with your eyes, rinse with
water and seek immediate medical attention. Fluid leaking from batteries

can lead to irritation or burns.
Do not operate the battery charger on easily inflammable surfaces or in
combustible environments. The heat produced during the charging
process may pose a fire hazard.
Ensure sufficient ventilation whilst charging. Do not operate the battery
charger in enclosed cabinets or in close vicinity to heat sources and keep
it out of direct sunlight. Ambient temperatures in excess of +50oC can
lead to malfunctions.
Never attempt to recharge non-rechargeable batteries.
The battery charger is not intended to be used by persons (including
children) with limited physical, sensory or mental capabilities, or lack of
experience and/or knowledge, except if being supervised by a person
responsible for their safety or having received instructions from this
person on how to operate the device.
Keep the battery charger away from rain or moisture. Exposure of an
electrical device to water increases the risk of an electric shock.
Before each use, check the battery charger, battery pack, cable and plug
for signs of damage. Do not use the battery charger if damage is
detected. Never open the battery charger. Repairs must be carried out
only by the manufacturer or by a qualified electrician. Damaged battery
chargers, cables and plugs increase the risk of an electric shock.
Do not dispose of used batteries in the household waste. Consult your
local authority or dealership for details of recycling or disposal facilities.
