Planing operation
First, rest the tool front base flat upon the
workpiece surface without the blades mak-
ing any contact. Switch on and wait until
the blades attain full speed. Then move the
tool gently forward. Apply pressure on the
front of tool at the start of planing, and a t
the back
a t
the end of planing. Planing will
be easier if you incline the workpiece in
stationary fashion, so that
you
can plane
somewhat downhill. T h e speed and depth
of cut determine the kind of finish. The
power planer keeps cutting
a t a
speed that
will not result in jamming by chips. For rough cutting, the depth of cut can be increased,
while for
a
good finish
you
should reduce the depth of cut and advance the tool more
slowly.
