1. Use recommended size tractor. See Specifications section.

2. Be sure tractor and machine have been properly prepared. See Preparing the Tractor and Preparing the Machine sections.

3. Check seed rates carefully.

4. Check tire pressure before seeding.

5. Allow tractor hydraulic oil to warm up thoroughly prior to seeding. Cold oil will cause slower fan speeds.

6. Run fan at recommended speed; excessive speed will cause increased wear on air system and damage seed.

7. Whenever machine has been standing for an hour or more during period of high humidity or damp, rainy days, or after sitting overnight, run fan at recommended rpm, with machine stationary for 10 minutes.

IMPORTANT: In adverse operating conditions (heavy crop residue, wet grass, slopes), additional ballast and/or slower operation may be required to maintain traction and proper control.

8. Operate at a ground speed of 6.4 km/h to 12.9 km/h (4 mph to 8 mph).

9. Control product application with switches in tractor or remote seeder switch. To avoid meter overload, only engage clutches when fan is turning.

10. To avoid plugging, have machine moving forward before lowering openers.

11. Raise openers fully out of the ground before making sharp turns or backing machine.

12. To prevent skipping, back machine up 5 m (15 ft) after stopping.

13. Use clean seed for best metering.

CAUTION: To keep from being severely injured, handle and apply fertilizers and chemically treated seeds according to manufacturers recommendations.

14. Avoid using fertilizers such as 46-0-0 that absorb moisture readily, especially during periods of high humidity. Also avoid fertilizers that contain a high percentage of fine dust, as these materials can plug meter rollers and coat the inside of seed distribution system.

15. For even metering run-to-run, in-tank product level should be kept above 152 mm (6 in.) minimum. When product level falls below 6 inches, pressure disturbances inside the tank adversely affect product delivery to the meter inlets. Do not run tank completely empty; refill when product level indicator first shows empty condition [approximately 304 mm (12 in.) of product still in tank].

16. After each day of operation, empty remaining product from tank and clean caked-on material from manifolds and rollers. Open tank lids and remove any obstructions (rocks, twigs, sticks, straw, etc.) from meter inlet openings.

More frequent cleaning (possibly as often as every other tank fill) is recommended when product contains a high level of debris (rocks, twigs, sticks, straw, etc.).

17. Recognize and correct warning and alarm conditions as indicated on the display monitor.

18. When using stationary double-shoot manifold system:

• Larger seed, such as soybeans or chickpeas, should always feed into the top primaries.

• Airflow distribution (damper position) should be set to always feed equal or higher rates through the top primaries.
• Regular inspection of the manifold bypass passages through the bottom manifold plugs is recommended.
• Material can collect in the valve assemblies on each end of the manifold as well as the center cover plate. Use of unclean seed, granular treatments, or fine fertilizers will require more frequent cleanout.
• Cycle the slide daily when product is in the tank to keep slide free.
• When operating under high-humidity conditions or during drizzle, moisture will enter the airstream and mix with metered material. As the

cart air passages dry naturally once parked, material may harden on the slide surfaces and hinder slide operation. Before parking cart after operating in moist conditions:
• Cycle slide back-and-forth several times with fan running to clear most material from passages.
• Cycle slide back-and-forth at start of next use.
• Unused primary tubes should be capped at the cart exit and plugged above the manifold. With the stationary double-shoot manifold system, material collection within these unused, capped primaries is typical. The cover plate on the bottom of the manifold should be removed regularly to drain collected material.
