at cutterhead speeds between 6000 and 11,000 RPM.
Speed indicators of 1-2-3-4 and 5 are provided on the
speed dial as shown. When the pointer (B) is pointing to
1, the cutterhead speed will be 6000 RPM; 2 – 7250
RPM; 3 – 8800 RPM; 4 – 9750 RPM; and 5 – 11,000
RPM.

A speed control chart (C) Fig. 23, indicates the recom-
mended cutterhead speed setting when jointing plastics,
soft woods and hard woods from 1-1/2" to 6" wide.

CUT ADJUSTMENT
The jointer can be set to cut any depth from a very thin
shaving to 1/8" deep. A dual English/Metric scale (A)
