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.
Changing the sanding sheet (hook and loop)
WARNING: Always switch off and disconnect from the power supply before changing the
sanding sheet.
1. Remove the old hook and loop sanding sheet, if fitted, by peeling it away from the
machine’s hook and loop Sanding Base (3)
2. Clean any dust or debris from the hook and loop sanding base
3. Align the dust extraction holes in the new sanding sheet with those of the base and
press the sheet firmly in place
Changing the sanding sheet (conventional non-hook-and-
loop sanding sheets)
WARNING: Always switch off and disconnect from the power supply before changing the
sanding sheet.
1. Release the Quick-Change Levers for Conventional Sanding Sheets (4) from both
sides of the Sanding Base (3). Remove any old sanding sheet
2. Clean any dust or debris from the sanding base and lever mechanisms
3. Align the dust extraction holes in the new sanding sheet with the holes of the
sanding base
4. Fit one side of the sheet under one of the quick-change levers and close the lever
5. Push the other end of the sanding sheet under the quick-change lever on the
opposite side of the sanding base. Push the sheet so it sits tightly in line with the
base, and close the second lever
WARNING: If the sanding sheet is not tightly clamped over the Sanding Base (3), it will
wear excessively. Always make sure the sanding base is completely covered by the
sanding sheets, as you might otherwise cause damage to the surface of the base and
the workpiece.
Note: If you are using conventional, non-hook-and-loop 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 hook and loop
surface of the base.
Operation
Switching on and off
WARNING: Always wear safety goggles, an adequate dust mask, hearing protection and
suitable gloves, when working with this tool.
WARNING: Never switch the sander on when the base is in contact with the workpiece or
any other surface, as this might cause the operator to lose control over the machine, and
lead to serious injury.
1. Connect the sander to the mains power supply
2. Squeeze the On/Off Trigger Switch (1) located below the main handle, to switch
the sander on
3. Release the trigger switch to switch the sander off
Note: If you wish the sander to remain on, squeeze the On/Off Trigger Switch (1), then push
the Lock-On Button (2) and release the trigger. The machine will continue to operate until
the trigger switch is squeezed again, whereby the lock-on button is released.
WARNING: Always wait until the machine has stopped vibrating completely before putting
it down. Always disconnect from the power supply after use.
Sanding
WARNING: Always wear safety goggles, an adequate dust mask, hearing protection and
suitable gloves, when working with this sander.
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.
WARNING: NEVER touch the moving sanding sheet.
Note: Always use clamps to secure your workpiece to the workbench wherever possible.
1. Grip both, the Main Handle (6) and Front Handle (7) firmly, and switch the sander on
2. Move the machine in a circular motion over the workpiece surface, applying an even,
moderate pressure (Fig. D). until you reach the desired surface finish
Note: Apply moderate pressure only. Excess pressure will not lead to a faster removal of
material, but will damage the sanding sheet and the machine.
3. If there are still scratches on your workpiece after sanding, try either of the following:
• Return to a coarser grit sanding sheet and sand the marks out before recommencing
with the original choice of sanding sheet or,
• Try using a new sanding sheet of the same grit to eliminate the unwanted marks before
progressing to a finer grit and finishing the job
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 hook and loop
surfaces, resulting in sanding sheets failing to attach properly.
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 inspection,
maintenance or 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
WARNING: ALWAYS wear protective equipment including eye protection and gloves when
cleaning this tool.
• Keep your tool clean at all times. Dirt and dust will cause internal parts to wear quickly,
and shorten the device’s service life
• Clean the body of your machine with a soft brush, or dry cloth
• Never use caustic agents to clean plastic parts. If dry cleaning is not sufficient, a mild
detergent on a damp cloth is recommended
• Water must never come into contact with the tool
• Ensure the tool is thoroughly dry before using it
• If available, use clean, dry, compressed air to blow through the ventilation holes (where
applicable)
Hook and loop surfaces
• Hook and loop surfaces need to be clean, free of dirt and foreign matter, such as hair,
fibres, sand etc.
• In order to provide adequate adhesion for securing accessories, hook and loop surfaces
must be in good condition
• When used extensively, hooks and loops will become elongated or broken, and the
mechanism will be unable to provide the required strength of adhesion
Note: This sander’s hook and loop Sanding Base (3) is NOT a warranty item. Replacement
plates can be fitted at an authorised Silverline service centre.
Storage
• Store this tool carefully in a secure, dry place, out of the reach of children
