The stated vibration emission value was

measured in accordance with a standard
testing procedure and may be used to com­pare one power tool to another.

The stated vibration emission value may

also be used for a preliminary exposure
assessment.

Warning!

The vibration emission value may

differ during actual use of the
power tool from the stated value
depending on the manner in which
the power tool is used.
Try to keep the exposure to vibra­tions as low as possible. Examples

2

of measures to reduce vibration
exposure are the wearing of gloves
when using the tool and limiting the
working hours. For this purpose all
parts of the operating cycle have to
be considered (for example, times
when the electric tool is switched
off and times when it is switched on
but running without any load).

General safety instructions

WARNING!

When using power tools, observe
the following basic safety measures
for the prevention of electric shocks
and the risk of injury and re.
Please read all these instructions
before using the electric tools and
please keep the safety instructions.

The term “power tool” used in the safety in­structions refers to mains-operated electric
tools (with a mains cable) and to battery­operated electric tools (without a mains
cable).

Safe operation:

• Keep work area clear. Cluttered

areas and benches invite injuries.

• Consider work area environ-

ment.

- Do not expose tools to rain. Do not
use tools in damp or wet locations.
Water entering a power tool will in­crease the risk of electric shock.

- Keep work area well lit.

- Do not use tools in the presence of
ammable liquids or gases.
Power tools create sparks which may
ignite the dust or fumes.

• Guard against electric shock.
Avoid body contact with earthed or

grounded surfaces (e.g. pipes, radia­tors, ranges, refrigerators).

• Keep other persons away.
Do not let persons, especially children,

not involved in the work touch the tool
or the extension cord and keep them
away from the work area.

• Store idle tools. When not in use,

tools should be stored in a dry locked­up place, out of reach of children.

the job better and safer at the rate for
which it was intended.

• Use the right tool.

- Do not force small tools to do the job
of a heavy duty tool.

- Do not use tools for purposes not
intended; for example do not use cir­cular saws to cut tree limbs or logs.

Use of the power tool for operations dif-

ferent from those intended could result
in a hazardous situation.

• Dress properly.

- Do not wear loose clothing or jewel­lery, they can be caught in moving
parts.

- Anti-slip footwear is recommended
when working outdoors.

- Wear protective hair covering to con­tain long hair.

• Use protective equipment.

- Use safety glasses.

- Use face or dust mask if working op­erations create dust.

• Connect dust extraction equip-

ment. If the tool is provided for the

connection of dust extraction and col­lecting equipment, ensure these are
connected and properly used.

• Do not abuse the cord. Never

yank the cord do disconnect it from the
socket. Keep the cord away from heat,
oil and sham edges.

• Secure work. Where possible use

clamps or a vice to hold the work. It is

safer than using your hand.

• Do not overreach. Keep proper foot-

ing and balance at all times.

This enables better control of the power

tool in unexpected situations.

• Maintain tools with care.

Many accidents are caused by poorly

maintained power tools.

- Keep cutting tools sharp and clean
for better and safer performance.

- Follow instruction for lubricating and
changing accessories.

- Inspect tool cords periodically and if

damaged have them repaired by an
authorized service facility.

- Inspect extension cords periodically

and replace if damaged.

- Keep handles dry, clean and free
from oil and grease.

• Disconnect tools. When not in use,

before servicing and when changing
accessories disconnect tools from the
power supply.

Such preventive safety measures reduce

the risk of starting the power tool acci-

dentaIly.

• Remove adjusting keys and
wrenches. Form the habit of checking

to see that keys and adjusting wrenches
are removed from the tool before turn­ing it on. A wrench or a key left at­tached to a rotating part of the power
tool may result in personal injury.

• Avoid unintentional starting.

Ensure switch is in “off” position when

plugging in.

• Use outdoor extension leads.
When the tool is used outdoors, use
only extension cords intended for out­door use and so marked.

• 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 inuence of drugs,

alcohol or medication. A moment of
inattention white operating power tools
