NOTE: The figures are emission levels and are not necessarily safe working levels. Whilst there
is a correlation between the emission and exposure levels, this cannot be used reliably to
determine whether or not further precautions are required. Factors that influence the actual
level of exposure of the workforce include the characteristics of the workroom and the other
sources of noise, etc. i.e. the number of machines and other adjacent processes. Also, the
permissible exposure level can vary from country to country. This information, however, will
enable the user of the machine to make a better evaluation of the hazard andrisk.

General 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 of these instructions before attempting to operate this product and save
theseinstructions.
SAVE THIS MANUAL FOR FUTURE REFERENCE
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.
- Ensure the mitre saw is mounted or placed on a level, firm work surface before use. A level
and firm work surface reduces the risk of the mitre saw becoming unstable.
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 with 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 collection facilities, ensure
that these are connected and properlyused.
