PRODUCT SAFETY
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, re
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.
Unmodied 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 loca-
tion 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 connect-
ing to power source and/or battery pack,
picking up or carrying the tool.
Carrying
power tools with your nger 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, jewel -
lery or long hair can be caught in moving parts.
g) If devices are provided for the connection of
dust extraction and collection facilities, en-
sure 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 can -
not 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 misalign-
ment 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 ac -
cidents 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

6
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 re
when used with another battery pack.
b) Use power tools only with specifically desig-
nated battery packs.
Use of any other battery
packs may create a risk of injury and re.
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
re.
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.
6. Service
a) Have your power tool serviced by a qualified
repair person using only identical replace-
ment parts.
This will ensure that the safety of
the power tool is maintained.
