The procedures for adjusting the auger and spreadroll
chains are the same (it does not matter which you
inspect/adjust rst):
1. Remove the three(3) bolts holding on the chain
cover. (Figure 5-10)
2. Remove cover and inspect chains for slack.
3. If chain(s) has too much slack, loosen the four motor
mount bolts:
• Adjust chain tension (refer to Figure 5-9 and
Table 5-3). DO NOT overtighten.
4. Reinstall chain cover.

Spreadroll Seals
The spreadroll seal runs along the length of the
spreadroll and should be checked every 50 hours for
proper adjustment.
Adjusters
Figure 5-11. Spreadroll Seal Adjusters
To adjust the spreadroll seals:
1. Extend the spreading gates completely.
2. Loosen the adjuster bolts. (Figure 5-11)
3. Slide the spreadroll seal to obtain an even 1/16-inch
(1.59 mm) gap between the seal and the spreadroll,
then retighten each bolt.
