2. GENERALSAFETYRULES
WARNING: Read all safety warningsand 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.
2.1 WORK AREA SAFETY
a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.
b) Do not operatepower toolsin explosive atmospheres,such as in the presence of
flammable liquids gasesor dust. Power tools create sparks which may ignite the dust or
fumes
cKeep children and bystanders away while operating apower tool. Distractionscan
cause you to lose control.

2.2 ELECTRICAL SAFETY
a) Power tool plugs must match the outlet.Never modify the plug in any way. Do not use
any adapter plugswith earthed (grounded) power tools. Unmodified plugs and matching
outlets will reduce risk of electric shock.
bAvoid body contact with earthed or grounded surfaces, such as pipes,radiators,
ranges and refrigerators.There is an increased riskof electric shock if your body isearthed
or grounded.
cDo not expose power toolsto rain or wet conditions.Water entering apower toolwill
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 the cord away from heat, oil, sharp edges and moving parts. Damaged or
entangled cords increase the risk of electric shock
e) When operating apower tool outdoors,use an extension cord suitablefor outdoor use.
Use of a cord suitable for out-door use reduces the risk of electric shock.
f) If operating apower tool in adamp location is unavoidable, use aresidual current device
(RCD) protected supply.Use of an RCD reducesthe risk of electric shock.
2.3 PERSONAL SAFETY
a) Stay alert,watch what you are doing and use common sense when operating apower
tool. Donot use apower tool while you are tired or under the influenceof drugs, alcohol or
medication. Amoment of distraction whileoperating power toolsmay result in serious
person al injury.
b) Usepersonal 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. Awrench 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 toolin unexpected situations.
f) Dress appropriately. Do not wear loose clothing or jewelry.Keep your hair, clothing and
glovesaway from moving parts. Loose clothes, jewelryor long haircan be caught in
moving parts.
g) If devicesare 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.
2.4 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 atthe rate for which it was designed.

5
b) Do not usethe power tool ifthe switch does not turn it on and off. Anypower 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 idlepower toolsout of the reach of children and do not allow persons unfamiliar
with the power tool or these instructions to operatethe power tool.Power tools are
dangerous in the handsof 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’soperation.If damaged, have
the power tool repaired before use.Manyaccidents are caused by poorly maintained
power tools.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting
edgesare less likely to bind and are easier to control.
g) Usethe power tool, accessoriesand tool bitsetc. inaccordance with these instructions,
taking into account the working conditions and the workto be performed. Use ofthe power
tool for operationsdifferent from those intended could resultin a hazardous situation.
2.5 BATTERY TOOL USE AND CARE
