When using Power Tools, always observe the safety regulations applicable in your country to reduce the risk of fire, electric shock and personal injury. Read the following safety instructions before attempting to operate this product. Keep these instructions in a safe place!
General
1 Keep work area clean Cluttered areas and benches can cause accidents.
2 Consider work area environment
Do not expose Power Tools to humidity. Keep work area well lit. Do not use Power Tools in the presence of flammable liquids or gases.
3 Guard against electric shock
Prevent body contact with earthed surfaces (e.g. pipes, radiators, cookers and refrigerators). For use 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 children away
Do not let children come into contact with the tool or extension cord. Supervision is required for those under 16 years of age.
5 Extension cords for outdoor use
When the tool is used outdoors, always use extension cords intended for outdoor use and marked accordingly.
6 Store idle tools
When not in use, Power Tools must be stored in a dry place and locked up securely, out of reach of children.
7 Dress properly
Do not wear loose clothing or jewellery. They 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.
8 Wear safety goggles
Also use a face or dust mask in case the operations produce dust or flying particles.
9 Beware of maximum sound pressure
Take appropriate measures for the protection of hearing if the sound pressure of 85 dB(A) is exceeded.
10 Secure workpiece
Use clamps or a vice to hold the workpiece. It is safer and it frees both hands to operate the tool.
11 Do not overreach
Keep proper footing and balance at all times.
12 Avoid unintentional starting
Do not carry the plugged-in tool with a finger on the switch. Be sure that the switch is released when plugging in.
13 Stay alert
Watch what you are doing. Use common sense. Do not operate the tool when you are tired.
14 Disconnect tool
Shut off power and wait for the tool to come to a complete standstill before leaving it unattended. Unplug the tool when not in use, before servicing or changing accessories.
15 Remove adjusting keys and wrenches
Always check that adjusting keys and wrenches are removed from the tool before operating the tool.
16 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.
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.
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 Maintain tools with care
Keep the tools in good condition and clean for better and safer performance. Follow the instructions for maintenance and changing accessories. Inspect the tool cords at regular intervals and, if damaged, have them repaired by an authorized DEWALT repair agent. Inspect the extension cords periodically and replace them if damaged. Keep all controls dry, clean and free from oil and grease.
19 Check for damaged parts
Before using the tool, carefully check it for damage to ensure that it will operate properly and perform its intended function.
Check for misalignment and seizure of moving parts, breakage of parts and any other conditions that may affect its operation. Have damaged guards or other defective parts repaired or replaced as instructed.
Do not use the tool if the switch is defective. Have the switch replaced by an authorized DEWALT repair agent.
20 Have your tool repaired by an authorized DEWALT repair agent
This Power Tool is in accordance with the relevant safety regulations. To avoid danger, electric appliances must only be repaired by qualified technicians.
Additional safety rules for grinders
- Your grinder has been designed for grinding and cutting masonry and steel.

Do not cut or grind light metal with a magnesium content exceeding 80% since this type of metal is flammable.
- Do not use any accessories other than fibre reinforced grinding wheels and cutting disks.
- Use the grinding wheels and cutting disks recommended by the manufacturer only.
- The no-load speed of the grinding wheel or cutting disk must not exceed the value printed on the nameplate (instruction sheet).
- Do not cut workpieces requiring a maximum depth of cut exceeding that of the cutting disk.
Package contents
The package contains:
1 Angle grinder
1 Guard
1 Side handle
1 Flange set
1 Two-pin spanner
1 Kitbox (K-models only)
1 Instruction manual
1 Exploded drawing
- Check for damage to the tool, parts or accessories which may have occurred during transport.
- Take the time to thoroughly read and understand this manual prior to operation.
Description (fig. A)
Your angle grinder has been designed for professional grinding and cutting applications. Sanding requires a special rubber backing pad available as an option.
1 ON/OFF-switch
2 Side handle
3 Guard
4 Spindle lock
DW822, DW825(K) & DW826(K) -
Soft start feature
The soft start feature allows a slow speed build-up to avoid an initial jerk when starting. This feature is particularly useful when working in confined spaces.
DW822, DW825(K) & DW826(K) -
Constant speed control feature
The constant speed control feature maintains tool speed under load to assure optimum efficiency and productivity. It also functions as an overload feature.
DW822, DW825(K) & DW826(K) -
Overload protection
The unit will automatically stop drawing current if the motor is being overloaded. For optimum efficiency and to avoid damaging the motor, do not overload the motor for long periods.
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.

Your DEWALT 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 authorized DEWALT repair agent or a qualified electrician.
- Disconnect the plug from the supply.
-
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 below). Brown is for Live (L) (2) and 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 two leads are correctly fixed at the terminal screws.

Never use a light socket.
Never connect the live (L) or neutral (N) wires to the earth pin marked E or 12
For 115 V units with a power rating exceeding 1500 W, we recommend to fit a plug to BS4343 standard.
Using an extension cable
If an extension cable is required, use an approved extension cable suitable for the power input of this tool (see technical data). The minimum conductor size is 1.5 mm^2 . When using a cable reel, always unwind the cable completely.
Also refer to the table below.
| Conductor size (mm2) Cable rating (Amperes) |
