Blade speed or stroke rate is controlled by
a trigger style switch under the handle.
Speed increases as the trigger is pulled.
There is also a recessed circular switch in
the trigger which controls the maximum
stroke rate. See Figure 6 .. The switch is
marked with ranges from 1 to 6 where 1 is
the lowest stroke rate and 6 is the highest.
The adjustment is infinitely variable
between settings.
The proper speed depends upon the type
of material and the blade. Experiment with
a scrap piece of material when first making
a cut to see how the cutting action and
smoothness is. Adjust the blade speed
and the rate of feeding the blade into the
work until the action is smooth and the
motor does not slow down excessively.

The toggle switch next to the orbital move-
ment selector controls the chip blowing
device shown in Figure 7 .. When set as
shown in the photograph, the amount of air
is at its highest level. This is suitable for
cutting in wood when it is desirable to blow
the sawdust out of the way to see the cut
line. There are two additional settings
which progressively reduce the amount of
air delivered. The lowest setting may be
used for cutting in metal where cutting oil is
being used and it is not desirable to have
air move the oil away from the cutting sur-
face.
