Clean Vacuum System

Dirt or seed treatment builds up in the vacuum manifold system and causes low vacuum at planting units. Unclean vacuum manifold system results in loss of seed meter accuracy.

CAUTION: Follow chemical manufacturers label when handling parts coated with seed treatments. Use proper skin, eye, and respiratory protection.

Clean air system at least once a week during operation or more often in severe dusty conditions.
