SAFETY GENERAL SAFETY INSTRUCTIONS 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.

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

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.

Unmodifi ed plugs and matching outlets will reduce risk

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

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

f) If operating a power tool in a damp location is

unavoidable, use an earth leakage circuit breaker.

Use of an earth leakage circuit breaker reduces the risk

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

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 fi 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

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

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

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.

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

different or poorly maintainted accessories, may

signifi cantly increase the exposure level

- the times when the tool is switched off or when it is

running but not actually doing the job, may

signifi cantly reduce the exposure level

! protect yourself against the effects of vibration by

maintaining the tool and its accessories, keeping

your hands warm, and organizing your work
