dial. The blade stroke rate may be adjusted
during cutting operation by presetting the dial

ELECTRONIC FEEDBACK CIRCUITRY (EFC)
The internal electronic feedback system
helps to keep the no load speed virtually
constant between no-load and load
conditions.
The stroke rate may be adjusted as described
earlier under "Variable Speed Dial". The best
results for a particular application is determined
by experience, though as a general rule, slower
speeds are for denser materials and faster
speeds are for soft materials.
