5. USING THE SANDER
Your sander is equipped with a teardrop base
which allows you to use it on large flat surfaces,
as well as difficult and confined areas.
The workpiece to be sanded must be secured. If
it is small or it may move during sanding, it must
be held in a vice or suitably clamped.
Be sure to hold the sander firmly while it is on
and apply it gently to the work, it may "kick" on
first contact. Hold the sander so that it is flat
on the work and move slowly, preferably with
a smooth, circular motion. Regularly check the
condition of the sanding paper and replace when
worn for best results.
6. FLUSH SANDING FACILITY
Your sander can sand flush on three sides of the
base-plate which allows easy access to corners
and edges of moulding.
7. 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 sandpaper and only move the sander
in the direction of the grain and never across the
grain.
Do not allow your sander to remain in the same
position otherwise you will remove material and
create and uneven surface.
8.SELECT THE RIGHT SAND PAPER
Selecting the correct grit of sandpaper is an
extremely important decision that will allow you
to achieve the best quality sanding finish.
Coarse grit will remove the most material and
finer grit will give you the best finish in all sanding
operations. The condition of the surface to be
sanded will determine which grit will do the job.
If the surface is rough:
Start with coarse grit (sold separately) and sand
until the surface is uniform. Then use medium
to remove any scratches left by the coarse grit.
Then use finer grit (sold separately) for finishing
the surface.
Note: Always continue sanding with each grit
until the surface is uniform.
WORKING HINTS FOR
YOUR SANDER
1. Your sander is useful for working on wood,
metal, painted surface. It will smooth surfaces
prior to painting, even where fillers have been
used and left proud.
2. Your sander is best suited to large flat
areas such as doors but can also be used on
skirting boards, windows, etc, provided they are
accessible.
3. Different types of sanding paper will allow
the sander to meet various needs. Different
grades of sanding paper are available, the higher
grade number, the finer the grit. For rough work
start with a low grade of grit (i.e. 80 grade) and
change to a higher, finer grade (i.e. 100 or 120)
for finishing. If you use a fine grade for rough
surfaces it will soon clog and need changing.
4. At all times, let the sander do the work-do
not force it or apply excessive pressure to
the sanding paper or it could wrinkle or tear.
Preferably, use a light circular motion.
5. If the surface shows excessive making
from the abrasive motion, you may be using a
grit which is too coarse or applying too much
pressure.
MAINTENANCE
Remove the plug from the socket before
carrying out any adjustment, servicing or
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 the supply cord is damaged, it must be
replaced by the manufacturer, its service agent
or similarly qualified persons in order to avoid a
hazard.
TROUBLESHOOTING
1. If your sander will not operate, check the
power at the mains plug.
2. If the sander does not abrade surface,
checking the sanding paper. If the sanding paper
has been worn, replace the new paper and try
