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.

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 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.

1 2 3 4

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)

Assembly and adjustment

Prior to assembly and adjustment always unplug the tool.

Fitting sanding sheets (fig. B)

• Fit the sanding sheets using both clamps (2) on the sanding base (6).
• Quick-fix sanding sheets can be attached directly to the special sanding base.

Perforating sanding sheets (fig. C)

Your orbital sander uses perforated abrasive.

A hole perforation jig (5) is available as an option to punch unperforated abrasive.

Proceed as follows:

• Fit the sanding sheet to the sanding base (6). See also fig. B.
• Press the jig (5) and the sanding base (6) together. Make sure that the jig guides (5.1) are located against the corners of the sanding base.

Fitting the brush frame with the extractor hood (DW634, option) (fig. D)

The use of the brush frame and extractor hood is recommended for very fine finish sanding operations (e.g. on high-grade veneers and marquetry work), for sanding filler, for sanding down lacquer or paint, coarse sanding and for brushing out pores prior to lacquering.

Proceed as follows:

6 • Push both parts of the extractor hood (4) onto the machine base and secure them by means of the six fixing bolts (10) at the side and the top.
- Place the bosses (3.1) at the front of the brush frame (3) in the notches (4.1) of the extractor hood (4). Attach the brush frame to the rear of the extractor hood (4.2) by pressing the brush frame until the locking pins (3.2) snap in position.

Instructions for use

Always observe the safety instructions and applicable regulations.

Sanding (fig. E)

• Press the ON/OFF-switch (1).
• If necessary, press the lock-on button (11) for continuous operation.
• Make sure all materials to be sanded are well secured.
• Apply only a gentle pressure to the workpiece. Excessive pressure does not improve the sanding effect, but only results in an increased load on the machine and causes the abrasive to tear.
• To stop the tool in continuous operation, press the ON/OFF-switch (1) briefly and release it immediately. Always switch OFF the tool when work is finished and before unplugging.

Fire hazard! Do not use the sander on magnesium.

Dust extraction

- Since woodworking with a sander produces dust, always install a dustbag (DW634 only) or connect a vacuum cleaner (DW634 & DW636), designed in compliance with the applicable Directives regarding dust emission. Proper dust extraction will only be achieved with perforated abrasive.

- Do not use a dustbag or vacuum cleaner when sanding metal.

DW634 - dustbag (fig. F)

• Attach the dustbag (8) to the dust extraction socket (7).
• For efficient dust extraction empty the bag when it is about one third full.

DW636 & DW634 - vacuum cleaner (fig. G & H)

• Connect the vacuum cleaner hose to the nozzle (13) (DW636) or to socket (7) (DW634).
• For the DW634, use the vacuum cleaner adaptor (9).

Consult your dealer for further information on the appropriate accessories.

Maintenance

Your DEWALT Power Tool has been designed to operate over a long period of time with a minimum of maintenance. Continuous satisfactory operation depends upon proper tool care and regular cleaning.

Lubrication

Your Power Tool requires no additional lubrication.

Cleaning

Keep the ventilation slots clear and regularly clean the housing with a soft cloth.
