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 all of this manual carefully before operating the tool.
Save this manual for future reference.
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 (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 Keep children away
Do not allow children, visitors or animals to come near the work area or to touch the tool or the mains cable.
4 Dress properly
Do not wear loose clothing or jewellery, as these can be caught in moving parts. Wear protective hair covering to keep long hair out of the way. When working outdoors, preferably wear suitable gloves and non-slip footwear.
5 Personal protection
Always use safety glasses. Use a face or dust mask whenever the operations may produce dust or flying particles. If these particles might be considerably hot, also wear a heat-resistant apron. Wear ear protection at all times.
6 Guard against electric shock
Prevent 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 (Fl) earth-leakage circuit-breaker.
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 adjusting keys and wrenches
Always check that adjusting keys and 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 and marked accordingly.
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 replaced by an authorised DEWALT repair agent. Never attempt any repairs yourself.
15 Unplug tool
Switch off and wait for the tool to come to a complete standstill before leaving it unattended. Unplug the tool when not in use, before changing any parts of the tools, accessories or attachments and before servicing.
16 Avoid unintentional starting
Do not carry the tool with a finger on the switch. Be sure that the tool is switched off before plugging in.
17 Do not abuse cord
Never carry the tool by its cord. Never pull the cord to disconnect from the socket. Keep the cord away from heat, oil and sharp edges.
18 Store idle tools
When not in use, tools must be stored in a dry place and locked up securely, out of reach of children.
19 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. Keep all handles and switches dry, clean and free from oil and grease.
20 Repairs
This tool is in accordance with the relevant safety regulations. Have your tool repaired by an authorised DEWALT repair agent. Repairs should only be carried out by qualified persons using original spare parts; otherwise this may result in considerable danger to the user.

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 1± .
For 115V units with a power rating exceeding 1500W , 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 1.5mm^2
When using a cable reel, always unwind the cable completely.
Also refer to the table below.
| Conductor size (mm2) | Cable rating (Amperes) | ||||||
| 0.75 | 6 | ||||||

Instructions for use

- Always observe the safety instructions and applicable regulations.

- Apply only a gentle pressure to the tool. Excessive force does not speed up drilling but decreases tool performance and may shorten tool life.
Prior to operation:
- Insert the appropriate bit.
- Mark the spot where the hole is to be drilled.
Switching on and off (fig. A)
- To run the tool, press the variable speed switch (1). The pressure exerted on the variable speed switch determines the tool speed.
- For continuous operation, press and hold down the variable speed switch, press the lock-on button (2) and release the switch.
- To stop the tool, release the switch.
- To stop the tool in continuous operation, press the switch briefly and release it. Always switch off the tool when work is finished and before unplugging.
