Safety Instructions
WARNING! When using electric tools basic safety precautions should always be followed
to reduce the risk of fire, electric shock and personal injury including thefollowing.
Read all these instructions before attempting to operate this product and save theseinstructions.

General Safety Rules
1 . Keep work areaclear.
Cluttered areas and benches inviteinjuries.
2 . Consider work areaenvironment.
Do not expose the tool to rain. Do not use the tool in damp or wet conditions. Keep the
work area well lit (250–300 Lux). Do not use the tool where there is a risk of causing fire or
explosion, e.g., in the presence of flammable liquids andgases. Work area should be well
ventilated.
3 . Guard against electricshock.
Avoid body contact with earthed surfaces (e.g., pipes, radiators, cookers and refrigerators).
When using the tool under extreme conditions (e.g., high humidity, when metal swarf is being
produced, etc.), electric safety can be improved by inserting an isolating transformer or a (FI)
earth-leakage circuit-breaker.
4 . 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.
5 . Store idletools.
When not in use, tools must be stored in a dry place and locked
up securely, out of reach ofchildren.
6 . Do not force thetool.
It will do the job better and safer at the rate to which it wasintended.
7 . 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.
8 . Dressproperly.
Do not wear loose clothing or jewellery, as these can be caught in moving parts. Non-skid
footwear is recommended when working outdoors. Wear protective hair covering to contain
longhair.
9 . Use protectiveequipment.
Always use safety glasses. Use a face or dust mask if working operations create dust or flying
particles. If these particles might be considerably hot, also wear a heat-resistant apron. Wear
ear protection at all times. Wear a safety helmet at alltimes.
10 . Connect dust extractionequipment.
If devices are provided for the connection of dust extraction and collecting equipment, ensure
these are connected and properlyused.
11 . Do not abuse thecord.
Never yank the cord to disconnect it from the socket. Keep the cord away from heat, oil
and sharp edges. Never carry the tool by itscord.
12 . Securework.
Where possible use clamps or a vice to hold the work. It is safer than using your hand and it
frees both hands to operate thetool.

The vibration emission level given in this information sheet has been measured in accordance
with a standardised test given in EN61029 and may be used to compare one tool with another.
It may be used for a preliminary assessment ofexposure.

WARNING: The declared vibration emission level represents the main applications of the
tool. However if the tool is used for different applications, with different accessories or
poorly maintained, the vibration emission may differ. This may significantly increase the
exposure level over the total workingperiod.
An estimation of the level of exposure to vibration should also take into account the times
when the tool is switched off or when it is running but not actually doing the job. This
may significantly reduce the exposure level over the total workingperiod.
Identify additional safety measures to protect the operator from the effects of vibration
such as: maintain the tool and the accessories, keep the hands warm, organisation of
workpatterns.

NOTE: This device is intended for the connection to a power supply system with maximum
permissible system impedance Zmax of 0.28 Ohm at the interface point (power service box) of
user’ssupply.
The user has to ensure that this device is connected only to a power system which fulfils the
requirement above. If necessary, the user can ask the public power supply company for the
system impedance at the interfacepoint.
