but use a coarser grit size.
7. SELECTING THE RIGHT GRADE OF
SANDPAPER
Different grades of sanding paper can be
purchased from good DIY shops. Available
grades are Coarse, Medium and Fine.
Use coarse grits to sand down rough finishes,
medium grit to smooth the work and fine grit
to finish off.
The higher the grade number, the finer the grit.
For rough work start with a low grade of grit.
(e.g. 60 grit) and change to a higher, finer grade
(e.g. 100 or 120 grit) for finishing. If you use a
fine grade for rough surfaces it will soon clog
and need changing.
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.
8. PAD BRAKE
Your sander is equipped with a pad brake that
prevents over-speeding of the pad. If the tool
is lifted off the work surface while the motor
is running, the brake will limit pad rotation to
avoid unwanted sanding marks and gouges.
WORKING

YOUR ORBITAL SANDER
If your power tool becomes too hot, especially
when used at low speed, set the speed to
maximum and run it with no load for 2-3
minutes to cool the motor. Avoid prolonged
usage at very low speeds. Always use sand
paper that is suitable for the material you want
to sand.
Always ensure the work-piece is firmly held or
clamped to prevent movement.
Any movement of the material may affect the
quality of the sanding finish.
Start your sander before sanding and turn it off
only after you stop sanding. For the best results,
sand wood in the direction of the grain.
Do not start sanding without having the
sandpaper fitted.
Do not allow the sandpaper to wear away it will
damage the base-plate.The guarantee does not
cover base-plate wear and tear.
Use coarse grit paper to sand rough surfaces,
medium grit for smooth surfaces and
fine grit for the final surfaces. If necessary, first
make a test run on scrap material.
Use only good quality sandpaper.
The sandpaper controls the sanding efficiency,
not the amount of force you apply to

the tool. Excessive force will reduce the sanding
efficiency and cause motor overload. Replacing
the sandpaper regularly will maintain optimum
sanding efficiency.

MAINTENANCE

Your power tool requires no additional
lubrication or maintenance. There are no user
serviceable parts in your power tool. Never use
water or chemical cleaners to clean your power
tool. Wipe clean with a dry cloth. Always store
your power tool in a dry place. Keep the motor
ventilation slots clean. Keep all working controls
free of dust. If you see some sparks flashing in
the ventilation slots, this is normal and will not
damage your power tool.
