Helpful Hints
• Always ensure the workpiece is firmly held or
clamped to prevent movement. Any movement
of the material may affect the quality of the
cutting or sanding finish.
• Do not start sanding without having the
sandpaper attached to sanding platen.
• Use coarse grit paper to sand rough surfaces,
medium grit for smooth surfaces and fine grit for
the finishing surfaces. If necessary, first make a
test run on scrap material.
• Excessive force will reduce the working
efficiency and cause motor overload. Replacing
the accessory regularly will maintain optimum
working efficiency.
• Do not allow the sandpaper to wear away, it will
damage the sanding pad.
• If the tool overheats, 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 keep the blade sharp.
