SETTINGS AND ADJUSTMENTS
Knife Arm
The knife arm cuts the twine and strips it off of the
bill hook during the knotter's tying process.
The stripper flange on the knife arm should just
touch the bill hook with firm pressure as the stripper
flange advances the knot past the end of the bill
hook (see Figure 116).

The knife arm should be 1/4" to 3/4" past the end
of the bill hook when the knife arm is in the most
extreme position (see Figure 117). Correct the
adjustment of the knife arm by replac ing it.

Cam Gear Adjustment
Both flat surfaces of the knotter hook and worm
gear pinions must be held flat with 0 to .005 inter-
ference on the smooth face of the cam gears (see
Figure 118).
Make this adjustment with shims between the cam
gears and knotter frames. Shimming must be done
be tween the cam gears and the knotter frames any
time a knotter is assembled. Take out excess space
between the cam gears and the knotter frames
by adjusting nut (A), see Figure 119. Tighten nut
until knotters will just hold their own weight when
rotated up to horizontal.
