WARNING. Take care to regularly clean out the build up
of dust on the base underneath the sandpaper and not let
the sandpaper wear completely down before replacing it.
Failure to observe these two precautionary measures can
lead to damage to the platen.
Selecting the right grade of sandpaper
Different grades of sanding paper can be purchased from
your local hardware store.
Available grades are: Coarse, Medium and Fine.
Use a coarse grit to sand down rough finishes, medium grit
to smooth the work and fine grit to finish off.
It is best to make a trial run on a scrap piece of material
to determine the optimum grades of sandpaper for a
particular job.
Dust extraction
A vacuum cleaner adaptor can
be used to connect an ordinary
household vacuum cleaner to
the sander.
The adaptor (11) can be fitted
into the dust extraction port (9).

Maintenance
WARNING. Always ensure that the tool is switched off and
the plug is removed from the power point before making any
adjustments or maintenance procedures.
Keep the tool’s air vents unclogged and clean at
all times.
Regularly check to see if any dust or foreign matter has
entered the grills near the motor and around the
on/off switch. Use a soft brush to remove any
accumulated dust. Wear safety glasses to protect your
eyes whilst cleaning.
If the body of the tool needs cleaning, wipe it with a soft
damp cloth. A mild detergent can be used but nothing like
alcohol, petrol or other cleaning agent.
Never use caustic agents to clean plastic parts.
CAUTION. Water must never come into contact with
the tool.
Lubricate all moving parts at regular intervals.
General Inspection
Regularly check that all the fixing screws are tight.
They may vibrate loose over time.
Power cord maintenance
If the supply cord needs replacing, the task must be carried
out by the manufacturer, the manufacturer’s agent, or an
authorised service centre in order to avoid a safety hazard.
