General safety regulations

WARNING: Please read all safety instructions and advises.

wire) and battery powered electric tools (without power wire).

KEEP THESE SAFETY INSTRUCTIONS WELL.

1) Working place

a) Keep your working place clean and well lit.

Disordered and dark working places may lead to accidents.

In case of distraction, you might loose control over the device.

2) Electric safety

a) The power plug of the tools has to fit into the socket. The plug must not be modified in any

way. Never use adaptor plugs together with earthed electric tools.

Unmodified plugs and fitting sockets lower the risk of electric shock.

b) Avoid body contact with earthed surfaces like pipes, heaters, cookers and fridges.

It is a higher risk of electric shock if your body is earthed.

c) Keep tool away from rain and wet.

Penetration of water into an electric tool raises the risk of electric shock.

d) Do not divert the cable from its intended use to carry the tool, hang it or to pull the plug from

the socket. Keep the cable away from heat, oil, sharp edges and moving parts.

Damaged or ensnarled cables raise the risk of electric shock.

e) If you work with your electric tool outside, only use extended wires being suitable for outside

use.

Usage of extended wires, being suitable for outside use, can lower the risk of electric shock.

f) If you cannot avoid using the tool in a humid environment, use a suitable fuse protection.

Using a suitable fuse protection lowers the risk of electric shock.

g) Always use a Residual Current Device (RCD) (GFCI) / Earth Leakage Circuit Breaker / Safety Switch

when operating this item (electrical items only).

3) Personal safety

a) Be attentive, watch what you are doing and do your work with the electric tool with sanity. Do

not use any electric tool if you are tired, under drugs, alcohol or medicaments.

One moment of carelessness when using an electric tool can cause serious injuries.

b) Always wear personal protective equipment and always protection glasses.

Wearing of personal protective equipment like dust mask, anti-slip safety shoes, protection helmet or

ear protection, according to the kind of use of the electric tool, lowers the risk of injury.

c) Avoid accidental start-up. Make sure that electric tool is switched off before connecting it to

power supply , battery , lifting up or carrying.

Keep the finger on the switch when carrying the tool or connecting the tool to the power supply while

turned on can cause accidents.

d) Remove adjusting tools or wrenches before turning on the machine.

A tool or wrench, being in a moving part of the machine can cause injuries.

e) Avoid abnormal posture.

Stand safe and always keep the balance.

Thus you can better control the tool in unexpected situations.

f) Wear suitable clothing. Do not wear loose clothing or jewelry. Keep hair, clothes and gloves

away from movable parts.

Loose clothes, jewelry or long hair could be caught by movable parts.

g) When dust vacuum- and collection devices can be assembled, make sure that they are

connected and used properly.

Using a dust vacuum device can lower danger from dust.

4) Careful handling and use of electric tools

a) Do not overload the machine. Always use the electric tool being suitable for your work.

With the suitable tool you work safer and better in the given power range.

b) Do not use electric tools with a defect switch.

An electric tool which you cannot turn on or off is dangerous and must be repaired.

c) Pull the plug from the socket and/or remove the battery before you adjust the device, change

equipment or store the tool.

This will avoid accidental start-up of the electric tool.

d) Keep away unused electric tools from children. Do not let persons use the tool, which are not

used to it or never read this instruction.

Electric tools are dangerous when used by inexperienced persons.

e) Maintain the electric tool with care. Check if movable parts run properly and don’t trap, if

parts are broken or damaged and that the function of the tool is not affected. Repair damaged

parts before using the tool.

The cause of many accidents is bad maintained electric tools.

f) Keep cutting tools sharp and clean.

Well maintained cutting tools with sharp knife edges trap less and are easier to use.
