(3)Micromotor
1)Operation
Take the micromotor out of its holder and step on the foot pedal to
operate it. The display shows its approximate speed.
The chart to the right shows the speeds for variable speed mode(see
2)below). The maximum speeds can be lowered.(see 2) below for how
to set the maximum speed.)
If a variable micromotor is set for constant speed, it will run at the
maximum speed shown in the chart.
Tip air can be turned on or off for each speed range.
The motor could overheat if the tip air is turned off
for the medium and high speed ranges. Normally
please use the tip air after ON.
