Planing Operation - Makita 1911B Instruction Manual

For the correct planer blade setting
Your planing surface will end up rough and uneven,
unless the blade is set properly and securely. The blade
must be mounted so that the cutting edge is absolutely
level, that is, parallel to the surface of the rear base.
Below are some examples of proper and improper
settings.

(B) Rear base (Stationary shoe)

First, rest the tool front base flat upon the workpiece
surface without the blades making 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 at the back at the
end of planing. Planing will be easier if you incline the
workpiece in stationary fashion, so that you can plane
somewhat downhill.

The speed and depth of cut determine the kind of finish.
The power planer keeps cutting at 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.
