Adjusting Belt Tracking

IMPORTANT: If baler is equipped with net wrap, check for a 1-3 mm (0.039-0.118 in.) gap at the lower front belt guide straps. If there is too much gap, belts will not track correctly and cause damage to the belts. (See CHECKING AND ADJUSTING LOWER NET WRAP GUIDE in Service-Net Wrap section.)

NOTE: Belt tracking must be checked before adjustments are made. (See CHECKING BELT TRACKING in this section)
