FLUSH SANDING FACILITY
Your sander can sand flush on three sides of the baseplate which
allows easy access to corners and edges of mouldings (See F).

ORBITAL SANDING
Your sander operates in small circular rotations which allows efficient
material removal. Operate your sander in long sweeping movements
across your workpiece and even across the grain. For a finer finish,
always use a fine grain sanding paper and only move the sander in
the direction of the grit and never across the grain. Do not allow your
sander to remain in the same position otherwise you will remove
material and create an uneven surface.
Working hints for your finishing
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 sand paper 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 sand paper.
The sand paper 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 sand paper
regularly will maintain optimum sanding efficiency.
