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 by rubbing its smooth side over the
edge of a table (or similar)
2. Release the Paper Clamps (7) at the front and rear of the sander
3. Place one end of the sanding sheet into a clamp, and close the clamp tightly.
This will secure one end of the sheet
Note: Ensure the punched holes in the sanding sheet line up with the openings in
the base of the machine.
4. Stretch the sanding sheet over the Base Plate (6), and into the other paper
clamp. Keeping the paper taught, close this clamp tightly
• The sanding sheet is now attached to the sander, and the sander is 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
above
2. Press a punch plate against the underside of the Base Plate (6), the raised
points will punch the required holes in the paper
Dust extraction
IMPORTANT: It is essential to take proper measures (as described below) 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.
1. Connect the sander to a vacuum cleaner, or dust extraction system, using the
Dust Extraction Port (5)
2. 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
Switching on and 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, using both hands, on the handles provided
• To start the sander, depress the Trigger Switch (2); to stop the sander, release
the trigger switch
• This machine is also fitted with a Lock-on Button (3) for continuous operation.
To use this function, fully depress the trigger switch then press the lock-on
button
• You can now release the trigger switch and the machine will continue to operate
• Press the trigger switch again and then release it to stop the machine
WARNING: NEVER touch the moving sanding sheet.
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 machine
• Always start with a coarse grit paper, and work through progressively 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 machine 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 machine.
Accessories
• A full range of sanding sheets and accessories is available from your Silverline
dealer
Maintenance
WARNING: Always disconnect from the power supply before carrying out any
maintenance/cleaning.
General inspection
• Regularly check that all the fixing screws are tight. They may vibrate loose
over time
• Inspect the supply cord of the tool, prior to each use, for damage or wear.
Repairs should be carried out by an authorised Silverline service centre. This
advice also applies to extension cords used with this tool
Cleaning
• Keep your tool clean at all times. Dirt and dust will cause internal parts to wear
quickly, and shorten the machine's service life. Clean the body of your machine
with a soft brush, or dry cloth. If available, use clean, dry, compressed air to
blow through the ventilation holes
Storage
• Store this tool carefully in a secure, dry place out of the reach of children
Disposal
Always adhere to national regulations when disposing of power tools that are no
longer functional and are not viable for repair.
• Do not dispose of power tools, or other waste electrical and electronic
equipment (WEEE), with household waste
• Contact your local waste disposal authority for information on the correct way
to dispose of power tools
