Using the sander

The sander can be used for most sanding and polishing operations on materials such as wood, plastic, steel and painted surfaces.

CAUTION. Always wear safety goggles and a mask.

1.Grip the rear handle (9) in one hand and push down on the adjustable front handle (1) with the other hand. Hold the sander flat against the workpiece before switching on.

2.Switch the sander on and move it evenly over the work surface in a circular motion using only moderate pressure.

3.If marks remain in the work surface, try using a coarser grit before recommencing with the original grit choice. Alternatively try using a new disc of the same grit before going on to a finer grit and finishing the job.

4.For polishing, a lambs wool polishing bonnet (not supplied) can be purchased to fit the platen. When fitted and used with a good quality polish it can be used to polish paintwork to a high sheen. Use a low speed to

prevent burning the paintwork.

WARNING. Use great care when polishing and follow all polish manufacturers recommendations. Always test first on a small area which will not be seen.

Ensure any sanding grit residue is completely cleaned from the sander and platen before using as a polisher. If grit is present when polishing it can scratch the work surface. The manufacturer takes no responsibility for scratches resulting from sanding grit residue.

Adjusting the speed

The speed can be adjusted to suit the material being sanded.

To adjust the speed, move the variable speed control (6) until you are satisfied that the speed is what you need for the job in hand.

Fitting a sanding sheet

WARNING. Always ensure that the tool is switched off and the plug is removed from the power point before making any adjustments or maintenance procedures.

1.Before fitting sandpaper,

remove any dust or debris from the hooks and loops of the base.

2.Match the holes in a suitable sheet with the holes in the sanding base (3).

3.Simply press the sheet to the base to attach it.

4.To remove the sheet, peel it away from the base.

CAUTION. Take care to regularly clean out the build up of dust on the base underneath the sandpaper and not to let the sandpaper wear completely down before replacing it.

Failure to observe these two precautionary measures can lead to damage to the hooks and loops on the platen and the sandpaper will not attach properly.

WARNING: Never use the sander unless the entire base is
