are just behind the “gullets” of the blade teeth. Tighten

screw (E).

3. The upper blade support thrust bearing (G) Fig. 27

on an eccentric shaft. To change position of bearing (G),

use a straight screwdriver, rotate shaft (J) Fig. 28, until

the blade properly overlaps the support bearing. Then
