Unpacking
Due to modern mass production techniques, it is unlikely that your GMC Power Tool is faulty or that a part is missing. If you find anything wrong, do not operate the tool until the parts have been replaced or the fault has been rectified. Failure to do so could result in serious personal injury.
Switching on and off
1.With the cordset fitted to a power outlet, switch the sander on by pressing the “I” mark on the protective cover of the on/off switch (3).
2.To turn off the sander, press the “0” mark on the protective cover of the on/ off switch (3).
4.Move the sander over the surface of the work in a circular motion with an even, moderate pressure.
CAUTION. Where possible, clamp smaller workpieces to the bench.
NOTE. If there are still scratches on your work after sanding, try either of the following:
1.Go back to a coarser grit and sand the marks out before recommencing with the original grit.
2.Try using new sandpaper of the same grit to eliminate the unwanted marks before progressing to a finer grit and finishing the job.
Selecting the right grade of sandpaper
NOTE. It takes a few operations to get used to switching the sander on and off due to the protective cover. However, it is well worth the effort due to the protection afforded to the switch and the consequent increased lifetime of the unit.
