a recessed circular stroke rate switch in the
trigger also controls the maximum stroke
rate.the switch is marked with ranges from
+ to – to where – is the lowest stroke rate
and + is the highest. the adjustment is infi-
nitely variable between settings.
the proper speed depends upon the type
of material and the blade. experiment with
a scrap piece of material when first mak-
ing a cut to see how the cutting action and
smoothness is. adjust 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 amount of air is at its highest when
set as shown in
figure 9. this is suitable
for cutting in wood when it is desirable to
blow the sawdust out of the way to see the
cut line.
two additional settings 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 surface.
