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. Wear a safety helmet 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.

Additional safety instructions for sanders

Take special care when sanding some woods (e.g. beech, oak) and metal which may produce toxic dust. Wear a dust mask specifically designed for protection against toxic dust and fumes and ensure that persons within or entering the work area are also protected.

• Use this tool in a well-ventilated area when sanding ferrous metals. Do not operate the tool near flammable liquids, gases or dust. Sparks or hot particles from sanding or arcing motor brushes may ignite combustible materials.

Sanding paint

Observe the applicable regulations for sanding paint. Pay special attention to the following:

1 Whenever possible, use a vacuum extractor for dust collection.

2 Take special care when sanding paint which is possibly lead based:

• Do not let children or pregnant women enter the work area.

• All persons entering the work area should wear a mask specially designed for protection against lead paint dust and fumes.

• Do not eat, drink or smoke in the work area.

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)

Assembly and adjustment

Prior to assembly and adjustment always unplug the tool.

Fitting sanding sheets (fig. B1 & B2)

Fitting regular sanding sheets (fig. B1)

• Soften the sanding sheet by rubbing its non-abrasive side over the edge of a worktop.
• Release both sanding sheet clamp knobs (5).
• Slide the sanding sheet under the sanding sheet clamp (9).
• Engage the corresponding sanding paper clamp knob (5).
• Stretch the sanding paper firmly over the sanding pad (6) and repeat for the other clamp.

Fitting hook and loop sanding sheets (fig. B2)

• Fit the hook and loop sanding pad as described below.
• Place the tool on a table, sanding pad (6) up.
• Place the sanding sheet directly on top of the sanding pad.
• Hold the sanding pad (6) with one hand and align the dust extraction holes (10).
• Press the sheet firmly onto the sanding pad.

Changing the sanding pad (fig. C)

• Place the tool on a table, sanding pad (5) up.
• Remove the screws (11) holding the sanding pad to the base (12).

• Take the sanding pad from the base.

• Place the other sanding pad onto the base aligning the screw holes.

• Replace the screws (11) and tighten them.

Adjusting the front handle (fig. D)

The position of the front handle can be adjusted for optimum control.

• Loosen the knob (13) located in the centre of the front grip (4).
• Take the handle from the tool and place it on either mounting position.
• Make sure that the handle is placed correctly.
• Tighten the knob.

D26420/D26422 - Setting the electronic speed control dial (fig. A)

The speed is infinitely variable from 12,000 - 22,000 min ^-1 using the electronic speed control dial (3).

• Turn the electronic speed control dial to the required level. The correct setting, however, is a matter of experience.
• Generally, harder materials require a higher setting.

Dust extraction (fig. E)

Since woodworking with a sander produces dust, always install a dustbag designed in compliance with the applicable directives regarding dust emission.

Do not use a dustbag or vacuum extractor without proper spark protection when sanding metal.

• Fit the dustbag (8) into the frame (7) as shown.
• Attach the frame (7) to the dust extraction outlet (14).
• Turn the assembly clockwise to lock it in position.

Instructions for use

• Always observe the safety instructions and applicable regulations.

• 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.

• Avoid overloading.

Do not sand magnesium!

Switching on and off (fig. A)

• Switching on: press the on/off switch (1).
• For continuous operation, also press the lock-on button (2).
• Switching off: press the on/off switch again.

Sanding (fig. A)

• Start with the coarsest grit size.
• As the tool produces small scratch marks in all directions, it is not necessary to sand with the grain.
• Check your work at short intervals.
  Always switch off the tool when work is finished and before unplugging.

Replacing the dustbag (fig. E)

For efficient dust extraction replace the dustbag when it is about one third full.

• Carefully pull the dustbag opening (15) off the frame outlet (16) and remove the dustbag (8).
• Fit a new dustbag following the instructions as described above.

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
