Pneumatic Down Force Storage Procedures

When storing machine:

IMPORTANT: Do not remove air from system, air springs should be pressurized and may be allowed to leak down slowly to 0 psi.

• Park machine with 55 kPa (0.5 bar) (8 psi) of air pressure in the system.

When removing from storage:

CAUTION: Avoid serious injury from exploding parts due to overpressurization 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 a pinched or unrolled air spring . Should this occur, lower system pressure until springs can be rolled by hand. Roll spring back over lower piston. Incremental lowering of machine may be required to get rubber started rolling over the lower piston.

• Pressurize system to a minimum of 83 kPa (0.8 bar) (12 psi) before raising or lowering machine.
• Minimum system pressure during operation is 83 kPa (0.8 bar) (12 psi). Failure to hold 83 kPa (0.8 bar) (12 psi) during operation will result in damage to air springs.
