WARNiNG
Place all controls in neutral or off, stop combine engine,
set parking brake, remove ignition key, set cylinder
stops, wait for all moving parts to stop, then properly
block machine before servicing, adjusting, repairing or
unplugging.
NOTE
Although the adjustment can be made anywhere along
the adjustment slot, aligning the teeth tips with the indi-
cator point allows you to better identify the position of
the reel tine adjustment for both sides (Figure 80).
NOTE
The default pitch angle is with the 5th tooth (middle
tooth) on the eccentric mount plate assembly aligned
with the indicator mark on the RH & LH end clamps
(Figure 80).
