5. Safety rules

NOTE

The safety rules in section 5.1 contain all general safety rules for power tools which, in accordance with the applicable standards, require to be listed in the operating instructions. Accordingly, some of the rules listed may not be relevant to this tool.

5.1 General safety rules

WARNING! Read all instructions! Failure to follow all

instructions listed below may result in electric shock, fire and/or serious injury. The term “power tool” in

all of the warnings listed below refers to your mainsoperated (corded) power tool or battery-operated (cordless) power tool. SAVE THESE INSTRUCTIONS.

5.1.1 Work area safety

a) Keep work area clean and well lit. Cluttered and

dark areas invite accidents.

b) Do not operate power tools in explosive atmo-

spheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks

which may ignite the dust or fumes.

Page 8

c) Keep children and bystanders away while oper-

ating a power tool. Distractions can cause you to lose control.

5.1.2 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 con-

ditions. Water entering a power tool will increase theriskofelectricshock.

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.

5.1.3 Personal safety

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 safety equipment. Always wear eye pro-

tection. Safety equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.

c) Avoid accidental starting. Ensure the switch is

in the off-position before plugging in. Carrying power tools with your finger on the switch or plugging in 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 bal-

ance 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 these

devices can reduce dust-related hazards.

5.1.4 Power tool use and care

a) Do not force the power tool. Use the correct

power tool for your application.The correctpower

tool will do the job better and safer at the rate for which it was designed.

b) Do not use the power tool i f 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 prevent-

ive 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 and in the manner intended for the particular type of power tool, 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.

5.1.5 Battery tool use and care

a) Ensure the swit ch is in the off position before

inserting battery pack. Inserting the battery pack

into power tools that have the switch on invites accidents.

Page 9

b) Recharge only with the charger specified by the

manufacturer. A charger that is suitable for one typeofbatterypackmaycreateariskoffirewhen used with another battery pack.

c) Use power tools only with specifically designated

battery packs. Use of any other battery packs may create a risk of injury and fire.

d) 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.

e) Under abusive conditions, liquid may be ejec-

ted from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help.

Liquids ejected from the battery may cause irritation or burns.
