7. PAPER PUNCH (SEE FIG. M)
If using sanding paper without dust holes, use the paper
punch to perforate the holes to ensure correct dust
extraction. Position the punch over the base plate with the
punch sides on the edges of the base plate. Press the punch
into the base plate to punch holes into the sanding paper.
Then remove the punch and check all the holes have been
formed correctly.
8. USING THE SANDER
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 whilst 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.
9. FLUSH SANDING FACILITY
Your sander can sand flush on three sides of the baseplate
which allows easy access to corners and edges of
mouldings.
10. ORBITAL SANDING
Your sander operates in small a circular rotation 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 SANDER
1. 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.
2. Always ensure the work-piece is firmly held or clamped
to prevent movement.
3. Any movement of the material may affect the quality of
the sanding finish.
4. 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.
5. Do not start sanding without having the sandpaper
fitted.
6. Do not allow the sandpaper to wear away it will damage
the base-plate. The guarantee does not cover base-
plate wear and tear.
7. Use coarse grit paper to sand rough surfaces, medium
grit for smooth surfaces and ine grit for the final
surfaces. If necessary, first make a test run on scrap
material.
8. Use only good quality sandpaper.
9. The sandpaper controls the sanding efficiency, not
the amount of force you apply to he tool. Excessive
force will reduce the sanding efficiency and cause
motor overload. Replacing the sandpaper regularly will
maintain optimum sanding efficiency.
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. Occasionally you may
see sparks through the ventilation slots. This is normal and
will not damage your power tool.
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 again. The paper must be
kept in a dry place, if it is allowed to become damp, the
abrasive particles will lose their adhesion to the backing
paper and will not abrade.
3. If the sander dose not move smoothly, The sanding
paper may be loose, damaged or wrinkled. Replace and
try again.
4. If a fault can not be rectified return the sander to an
authorized dealer for repair.
