and correct the cause before use. Seek professional guidance if you are in doubt about how to
operate the tool safely.
• All discs and accessories must be checked before installation. If a disc is damaged in any
way, by being chipped, fractured, warped or misshapen, DO NOT USE AND DISCARD. If you are
unsure about whether a disc is safe to operate, DO NOT USE AND DISCARD.
• Do not allow discs to become wet or contaminated with oil. If you suspect that a disc has
degraded in storage, or if you are unsure about whether its expiry date has passed, DO NOT USE
AND DISCARD.
• Do not attempt to cut or grind magnesium or any alloy that has high magnesium content
• Hold the tool appropriately to ensure that debris produced does not land on skin or
clothing
• Do not operate the spindle lock while the sander is running
• Discs will continue to rotate for some time after the tool has been switched OFF. Allow the
moving parts to stop completely without interference. Do not try to stop the tool by holding
an object against the disc. NEVER place the sander down until the disc has completely
stopped moving.
• A sanding wheel or disc will gradually wear down during use, reducing its size. If a wheel
or disc becomes too small to work with easily, stop using it and replace it with a new disc.

Intended Use
Hand-held mains-powered drum sander for light- to medium-duty sanding tasks on wood, plastic,
metal and similar surfaces using either flap wheels or sanding sleeves mounted on a drum.
Unpacking Your Tool
• Carefully unpack and inspect your tool. Fully familiarise yourself with all its features and
functions
• Ensure all parts of the tool are present and in good condition. If any parts are missing or
damaged, have such parts replaced before attempting to use this tool.
Before Use
WARNING: Always disconnect this tool from the power supply before attaching or removing
accessories, or making any adjustments.
Selecting the correct sanding grit
• Sanding sleeves and flap wheels are available in a variety of different grades: coarse (60 grit),
medium (120 grit) and fine (240 grit)
• Use a coarse grit to sand down rough finishes, medium grit to smooth the work, and fine grit to
finish off
• Always use good quality sanding sleeves or wheels to maximise the quality of the finished task
• It is advisable to do a trial run on a scrap piece of material to determine the optimum grades for
a particular job. If there are still marks on your work after sanding, try either going back to a
coarser grade and sanding the marks out before recommencing with the original choice of grit,
or try using a new sanding sleeve or wheel to eliminate the unwanted marks before going on to
a finer grit and finishing the job.
Fitting a Sanding Sleeve to the Sanding Sleeve Drum
1. Remove the existing worn out Sanding Sleeve (19) from the Sanding Sleeve Drum (18).
2. Visually check the new Sanding Sleeve for damage or tears.
3. Check to see if there is a rotation direction indicated on the inside of the Sanding Sleeve and
match it to the Direction Indicator (7) marked on the tool. If necessary, fit the Sanding Sleeve
Drum to the tool to make it easier to ensure the direction is the same. Most sanding sleeves will
not be rotational.
4. Slide the Sanding Sleeve over the Sanding Sleeve Drum.
5. Check the Sleeve is secure on the drum before use.
Fitting and removing a Sanding Drum or Flap Wheel
IMPORTANT: The rated speed of the accessory must be at least equal to the maximum speed
marked on the power tool. Accessories running faster than their rated speed can break and fly apart.
Note: DO NOT continue to use worn, torn or heavily clogged Sanding Sleeves of Flap Drums/
Wheels. Ensure foreign objects, such as nails and screws, are removed from the workpiece before
starting to sand.
IMPORTANT: DO NOT use a Sanding Sleeve or Flap Drum/Wheel on wood that has previously been
used on metal. This may cause scouring on the wooden surface.
