damaged, have such parts replaced before attempting to use this tool
Before Use
Fitting Sanding Sheets
WARNING: Before fitting Sanding Sheets, ensure that the sander is disconnected from the power
supply.
Note: DO NOT continue to use worn, torn, or heavily clogged Sanding Sheets. Ensure foreign
objects, such as nails and screws, are removed from the workpiece before commencing sanding.
WARNING: DO NOT use a Sanding Sheet on wood that has previously been used on metal. This
may cause scouring on the wooden surface. DO NOT use this sander for sanding magnesium, or
for wet sanding.
Selecting the right grade of Sanding Sheet
Note: Always use good quality Sanding Sheets to maximise the quality of the finished task. Always
test the sander on a scrap piece of material to determine whether the Sanding Sheet is suitable for
the intended task:
• Coarse (60 grit) for use on rough material
• Medium (120 grit) for smoothing off
• Fine (240 grit) for finishing
Note: DO NOT use Sanding Sheets designed for wet sanding.
Fitting sheets with pre-punched holes
1. Reduce the rigidity of the Sanding Sheet (5) by rubbing its smooth side over the edge of a table
(or similar)
2. Release the Sanding Sheet Clamping Levers (6) at the front and rear of the sander (Fig. I)
3. Place one end of the Sanding Sheet into the clamp, and close the clamp tightly. This will secure
one end of the Sheet (Fig. II)
Note: Ensure the punched holes in the sanding sheet line up with the openings in the base of the
tool. (Fig. IV)
4. Stretch the Sanding Sheet over the Base Plate (7), and into the other sheet clamp. Keeping the
Sheet taught, clamp the sheet tightly (Fig. III)
• The Sanding Sheet is now attached to the sander and ready to use
Fitting sheets without pre-punched holes
Note: If you are using conventional Sanding Sheets with no punched holes, the dust extraction
system of this sander WILL NOT FUNCTION. Use a suitable tool to manually punch holes through the
Sanding Sheet, exactly where the dust extraction holes in the base of the sander are located. Take
care not to damage the surface of the Base.
1. Attach the Sanding Sheet to the sander using the same method as described for Sheets with
pre-punched holes.
2. Press a punch plate against the underside of the Base Plate (7); the raised points will punch the
required holes in the paper.

Dust extraction
IMPORTANT: It is essential to take proper measures to prevent dust entering the motor and other
internal mechanisms of this tool. Failure to do so may seriously reduce the life and performance
of this sander.
This can be done by connecting a suitable dust extraction system.
Connecting a dust extraction system
1. Connect the Dust Extraction Port (4) to the sander (Fig. V)
2. Connect the sander to a vacuum cleaner, or dust extraction system, via the Dust Extraction Port (4)
3. Turn the vacuum cleaner or dust extraction system on before you begin sanding
• This will significantly reduce the dust in the air around the work area
WARNING: When sanding metal, ensure your dust extraction system is suitable and free of any
remaining wood dust. Hot metal particles and sparks could ignite residual wood dust, and cause the
dust extraction system to catch fire. Always clean tools THOROUGHLY when switching from sanding
wood to sanding metal, and vice versa.
WARNING: Always connect the sander to a suitable vacuum cleaner or workshop dust extraction
system if the sanding dust contains harmful substances, such as particles from old paint, varnish,
surface coatings etc. Always dispose of harmful dust according to laws and regulations.
WARNING: Take special care to guard against harmful and toxic dusts when sanding lead-based
painted surfaces, woods and metals, particularly if you are unsure about the exact substances
involved. All persons entering the work area must wear a mask specially designed for protection
against the toxic dust and fumes involved. Children and pregnant women MUST NOT enter the work
area. DO NOT eat, drink or smoke in the work area.
Operation
WARNING: This sander is NOT suitable for wet sanding.
Switching 'ON' & 'OFF'
WARNING: Always wear safety goggles, an adequate dust mask, hearing protection and
suitable gloves, when working with this tool.
Note: Always use clamps to secure your workpiece to the workbench wherever possible.
• Always grip the sander firmly with both hands using the handles provided
• To start the sander, press the Trigger Switch (1). To stop the sander, release the Trigger Switch
• This tool is also fitted with a Lock 'ON' Button (2) for continuous operation. To use this function,
press the Trigger Switch then press the Lock 'ON' Button
• You can now release the Trigger Switch and the tool will continue to operate
• Press the Trigger Switch again and then release it to stop the tool
WARNING: NEVER touch the Sanding Sheet when the tool is switched 'ON' .
Sanding tips
• Do not bring the sander into contact with the workpiece until the motor has gained full speed.
Remove the sander from the workpiece before releasing the Trigger to stop the tool
• Always start with a coarse grit paper, and work through progressively to finer grit papers until the
desired finish is achieved
• Only apply moderate pressure to the sander. Pressing too hard onto the work surface may
overheat the motor or damage the workpiece
• Sand evenly over the work surface; as the tool works in an orbital motion it is not necessary to
work with the grain
• Only use the sander 'flat on' to the workpiece. Tilting the sander onto its edge will damage
your work
WARNING: Do not allow the sandpaper to completely wear down before replacing it. Failure to
observe these precautionary measures can lead to damage to the base of the tool.

General inspection
• Regularly check that all the fixing screws are tight. They may vibrate loose over time.

carried out by an authorised Silverline service centre. This advice also applies to extension cords
used with this tool.
