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
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.
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.
