Prior to beginning the harvest after winter storage,
take the following steps to be certain the unit is in
good condition.
1. Completely lubricate the unit (all grease points,
oil points, and fluid levels as noted in Section 3).
2. Check all belt and chain tensions and alignments
as detailed later in this section. Replace severely
worn chains and belts.
