2.17 Rotate the dehider blade one tooth (see step
2.11).
2.18 Repeat steps 2.16-2.17 for remaining teeth on
the dehider blade.
2.19 Turn off the electric switch (item 37).
2.20 Remove dehider blade and replace with un-

2.11 Tap the dehider blade tooth against the grinding
wheel until no additional material is removed
from the blade. Light taps will prevent burning
the tips of the blade.

er--clockwise slightly without disturbing the
relationship between the red dot on the dub ad-
just bushing and the reference line on bushing
(item 99).
2.13 Repeat steps 2.11--2.12 until all the machinist
blue is removed from the first tooth.
2.14 Rotate the adjust screw 1/4turn counter--clock-
wise without disturbing the dub adjust bushing
(item 101). The adjusting screw should not be
rotated until this blade set is complete.
2.15 Engage the pawl (item 94) in the first slot to the
left of the blade cut--out. Refer to Figure 5.

2.18 Repeat step 2.11.
2.19 Continue rotating the blade one tooth clockwise
until all teeth are sharpened.
2.20 Examine all teeth. If any machinist blue remains
on any teeth, return to step 2.8, and rotate the ad-
justing screw 1/8turn counter--clockwise with-
out disturbing the red dot or the dub adjust bush-
ing.
2.21 Repeat steps 2.11 -- 2.19.
2.22 When all teeth are sharpened, remove the blade
from the blade shaft and deburr the blade as de-
scribed in section 3, page 9.
2.23 Being careful not to disturb the adjusting screw
(item 103), place the second half of the blade set
on the blade shaft.
2.24 Tighten dehider blade in place with blade retain-
ing knob (item 91).
2.25 Repeat steps 2.8, 2.9, and 2.11. Note: Do not
