General
1. Keep work area clean
Cluttered areas and benches can cause accidents.
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. 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. Keep children away
Do not allow children, visitors or animals to come near the work area or to touch the tool or mains cable.
4. Dress properly
Do not wear loose clothing or jewellery, as these can be caught in moving parts. Preferably wear rubber gloves and non-slip footwear when working outdoors. Wear protective hair covering to keep long hair out of the way.
5. Personal protection
Always use safety glasses. Use a face or dust mask whenever the operations may produce dust or flying particles. Wear ear protection whenever the sound level seems uncomfortable.
6. Guard against electric shock
Prevent body contact with earthed or grounded surfaces (e.g. pipes, radiators, cookers and refrigerators). Electric safety can be further improved by using a high-sensitivity (30mA / 30mS) residual current device (RCD).
7. Do not overreach
Keep proper footing and balance at all times.
8. Stay alert
Watch what you are doing. Use common sense. Do not operate the tool when you are tired.
9. Secure workpiece
Use clamps or a vice to hold the workpiece. It is safer and it frees both hands to operate the tool.
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.
11. Remove keys and adjusting wrenches
Always check that keys and adjusting wrenches are removed from the tool before operating the tool.
12. Extension cables
Before use, inspect the extension cable and replace if damaged. When using the tool outdoors, only use extension cables intended for outdoor use.
13.Use appropriate tool
The intended use is described in this instruction manual. Do not force small tools or attachments to do the job of a heavy-duty tool. The tool will do the job better and safer at the rate for which it was intended. Do not force the tool.
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.
14. Check for damaged parts
Before use, carefully check the tool and mains cable for damage. Check for misalignment and seizure of moving parts, breakage of parts, damage to guards and switches and any other conditions that may affect its operation.
Ensure that the tool will operate properly and perform its intended function. Do not use the tool if any part is damaged or defective.
Do not use the tool if the switch does not turn it on and off. Have any damaged or defective parts repaired or replaced by an authorised repair agent. Never attempt any repairs yourself.
15. Unplug the tool
Unplug the tool when it is not in use, before changing any parts of the tool, accessories or attachments and before servicing.
16. Avoid unintentional starting
Do not carry the tool with a finger on the on/off switch. Be sure that the tool is switched off when plugging in.
17. Do not abuse cord
Never carry the tool by its cord or pull it to disconnect from the socket. Keep the cord away from heat, oil and sharp edges.
18. Store idle tools
When not in use, tools should be stored in a dry, locked up or high place, out of reach of children.
19. Maintain tools with care
Keep cutting tools sharp and clean for better and safer performance.
ENGLISH
Follow the instructions for maintenance and changing accessories. Keep handles and switches dry, clean and free from oil and grease.
20.Repairs
This tool complies with relevant safety requirements. Repairs should only be carried out by qualified persons using original spare parts; otherwise this may result in considerable danger to the user.
Additional safety instructions for angle grinders

Wear safety glasses or goggles when operating this tool.

Wear ear protection when operating this tool.

Wear gloves when operating this tool.

Do not cut or grind light metal with a magnesium content exceeding 80% , since this type of metal is flammable.
Only use grinding and cutting discs and other accessories recommended in this manual.
Make sure that the maximum speed of the grinding or cutting disc exceeds the no-load speed of the tool.
Do not cut workpieces requiring a maximum depth of cut exceeding that of the cutting disc.
- Never use the tool without the guard, except for sanding.
Do not exert side pressure on the grinding or cutting disc.
Sanding
Preferably wear a dust mask whenever sanding.
Thoroughly remove all dust after sanding.
Take special care when sanding paint which is possibly lead based or when sanding some woods and metal which may produce toxic dust:
-
Wear a dust mask specifically designed for protection against lead paint dust and fumes and ensure that persons within or entering the work area are also protected.
-
Do not let children or pregnant women enter the work area.
- Do not eat, drink or smoke in the work area.
- Dispose of dust particles and any other debris safely.
ELECTRICAL SAFETY
The electric motor has been designed for one voltage only. Always check that the power supply corresponds to the voltage on the rating plate.

This tool is double insulated in accordance with EN 50144; therefore no earth wire is required.
Mains plug replacement (U.K. & Ireland only)

Should your mains plug need replacing and you are competent to do this, proceed as instructed below. If you are in doubt, contact an authorised repair agent or a qualified electrician.
Disconnect the plug from the supply and remove the fuse from the plug.
Cut off the plug and dispose of it safely; a plug with bared copper conductors is dangerous if engaged in a live socket outlet.
Only fit 13 Amperes BS1363A approved plugs fitted with the correctly rated fuse (1).
The cable wire colours, or a letter, will be marked at the connection points of most good quality plugs. Attach the wires to their respective points in the plug (see above). Brown is for Live (L) (2), blue is for Neutral (N) (4).
Before replacing the top cover of the mains plug ensure that the cable restraint (3) is holding the outer sheath of the cable firmly and that the leads are correctly fixed at the terminal screws.
If the plug has a fuse cover, make sure that the fuse cover is fitted.
