IMPORTANT: Moistener system must keep spindles clean and slick. If buildup is allowed and spindle wrap occurs, moistener columns and doffers can be damaged.

NOTE: The less solution used to keep spindles clean and slick, the less trash and mud buildup occurs. Less buildup results in less maintenance.

Whenever spindle buildup is detected, review the following operational checklist and correct any problems found before changing operating parameters. If necessary, enact operating parameter changes one step at a time until spindle buildup is minimized.

Operational Checklist

□  Solution mix ratio. Mix solution in moistener tank at ratio of 21.25 L (5.6 gal.) John Deere Spindle Cleaner per 1363 L (360 gal.) (full tank) water.

□  Nozzle size. Use Number 3 size tip for John Deere Spindle Cleaner. (Be sure tip and tip strainer are not plugged.)

□  Cleaner. John Deere Spindle Cleaner.

□  Moistener system pressure. Press solution pressure button (A) to view pressure on display unit (B). Verify that system pressure is approximately 138 kPa (1.4 bar) (20 psi) with engine operating at high speed throttle position.

□  Moistener column. Verify that moistener columns are properly adjusted for height and position.

□  Moistener pads. Verify that moistener pads are not plugged.

Operating Parameter Changes

1. Increase solution mix ratio to 23.7 L (6.25 gal.) per 360 gal. (full tank) of water.

2. For normal to tough staining conditions, operate flush system at one end of field.

3. For extreme staining conditions, operate flush system at both ends of field.

4. If spindle buildup continues, increase solution pressure in 34 kPa (0.34 bar) (5 psi) increments.
