each belt at mid-span.
2. Tighten jam-nut on adjuster bolt (H) and
nuts (J).
o. Check reel drive chain tension. Total chain
slack at (N) should be 1/4 in. (6 mm).
If necessary, adjust as follows:
1. Loosen bolt (O) on sprocket, and jam-nut on
adjuster bolt (P).
2. Turn adjuster bolt (P) to move idler sprocket
“downward” until chain slack is achieved as
above.
3. Rotate auger and check chain for slack at
tightest point. Re-adjust position of idler
