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.
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.
13. Do not overreach.
Keep proper footing and balance at all times.
14. Maintain tools with care.
Keep cutting tools sharp and clean for better and safer
performance. Follow instructions for lubricating and changing
accessories. Inspect tools periodically and if damaged have
them repaired by an authorized service facility. Keep handles
and switches dry, clean and free from oil and grease.

15. Disconnect tools.
When not in use, before servicing and when changing accessories
such as blades, bits and cutters, disconnect tools from the power
supply.
16. Remove adjusting keys and wrenches.
Form the habit of checking to see that adjusting keys and
wrenches are removed from the tool before operating the tool.
17. Avoid unintentional starting.
Do not carry the tool with a finger on the switch. Be sure that the
tool is in the "off" position before plugging in.
18. Use outdoor extension leads.
Before use, inspect the extension cable and replace if damaged.
When the tool is used outdoors, use only extension cords intended
for outdoor use and marked accordingly.
19. Stay alert.
Watch what you are doing. Use common sense. Do not operate the
tool when you are tired or under the influence of drugs or alcohol.
20. Check for damaged parts.
Before use, carefully check the tool and mains cable to determine
that it will operate properly and perform its intended function.
Check for alignment of moving parts, binding of moving parts,
breakage of parts, mounting and any other conditions that may
affect its operation. A guard or other part that is damaged should
be properly repaired or replaced by an authorized service centre
unless otherwise indicated in this instruction manual. Have
defective switches replaced by an authorized service centre.
Do not use the tool if the switch does not turn it on and off.
Never attempt any repairs yourself.
WARNING! The use of any accessory or attachment or
performance of any operation with this tool other than
those recommended in this instruction manual may
present a risk of personal injury.
21. Have your tool repaired by a qualified person.
This electric tool complies relevant safety rules. Repairs should
only be carried out by qualified persons using original spare parts;
otherwise this may result in considerable danger to the user.
