Pneumatic Down Force Air Spring Storage Procedures

When Storing Machine

• IMPORTANT: Do not remove air from system. Air spring must be pressurized and allowed to leak down slowly to 0 psi.

  Park machine with 11 kg (25 lb.) of down force displayed on monitor or approximately 55 kPa (0.5 bar) (8 psi) on gauge.

Improperly Rolled Air Spring (Twin Row)

CAUTION: Avoid serious injury from exploding parts due to over-pressurization or operating the system without all components in place.

Do not inflate system above 827 kPa (8.2 bar) (120 psi).

Do not remove pressure relief valve.

Do not pressurize system unless all row unit components are in place.

IMPORTANT: Do not operate if a pinched or unrolled air spring occurs. Lower system pressure until air spring can be rolled by hand. Roll air spring back over lower piston. Incremental lowering of machine is required to start air spring rolling over lower piston.

When Removing Machine From Storage

• To fill the planters down force air springs for the first time after removing from storage:
  • In Auto mode, system begins filling the air springs to achieve the target margin when lowered to planting position.
  • In Set-Point mode, system begins filling the air springs to achieve the target down force when lowered to planting position.
• Pressurize system to a minimum of 16 kg (35 lb.) of down force displayed on monitor or approximately 83 kPa (0.8 bar) (12 psi) on gauge.
• Minimum down force during operation is 16 kg (35 lb.) displayed on monitor or approximately 103 kPa (1.0 bar) (15 psi) on gauge. Failure to maintain this pressure can result in damage to air springs.
