2. Turn the tool on and wait until the trimmer bit
attains full speed.
3.
Move the tool forward over the workpiece surface, keeping
the base ush and advancing smoothly until the cutting is complete.

NOTE:
Moving the tool forward too fast may cause a poor
quality of cut, or damage to the trimmer bit or motor. Moving
the tool forward too slowly may burn and mar the cut. The
proper feed rate will depend on the bit size, the kind of
workpiece and depth of cut. Before beginning the cut on the
actual workpiece, it is advisable to make a sample cut on
a piece of scrap lumber. This will show exactly how the cut
will look as well as enable you to check dimensions.
CAUTION:
Since excessive cutting may cause over-
load of the motor or diculty in controlling the tool, the depth
of cut should not be more than 3 mm at a pass when cutting
grooves. When you wish to cut grooves more than 3 mm deep,
make several passes with progressively deeper bit settings.
