speed using the setting dial 2 depending on the
area of application.
When under load, the digital electronic control
provides for more power.

3-4: Medium stroke rate
5-6: High stroke rate
-NOTE-
After longer periods of work at low stroke rate, the
machine can heat up considerably. Remove the
saw blade from the machine and allow the
machine to cool down by running it for approx. 3
minutes at maximum stroke rate.
