Adjusting Drive Belts
If the auger or wheels slip under load, belts could be
stretched or worn. Adjust as follows:
1.
Remove the belt cover (figure 10). Determine which
belt requires adjustment.
2. Loosen the locknut on the appropriate idler pulley
and move the idler pulley i/4” toward the belt (figure
11). Tighten the locknut.
3. Re-install the belt cover.
4. Determine if additional adjustment is required by try-
ing the unit. Repeat step
1
-
3 if necessary.
NOTE: If auger or wheels continue to slip after adjust-
ing the idler pulleys, the spring (figure
12)
on either con-
trol rod might be stretched and worn and require replace-
ment. Replace either
the
auger control rod spring or
drive control rod spring as necessary, then repeat steps
I-4.

lowing procedure.
