Priming and Initial Start Up of Pump

IMPORTANT: Avoid pump damage. Install vent plug (A) in pump crankcase. If pump has been removed from machine, remove solid plug from pump crankcase and replace with vent plug.

A - Vent Plug

B - Weep Hole

C - Lubrication Fitting

D - Oil Check and Fill Plug

It is normal for a SMALL amount of oil to leak from weep hole (B). The weep hole must remain open. Inspect at the beginning of each season. Too much grease at lubrication fitting (C) increases the chance of weep hole plugging or leaking grease.

Before priming, inspect fertilizer distribution system. Ensure that filter screen is clean and that there are no leaks in the pump suction line. Ensure that there are no pinched, kinked, or otherwise restricted hoses. Ensure that there are no extreme high or low variations in the path of hose. Inspect all orifices for debris and blockages. Ensure all 14 kPa (0.1 bar) (2 psi) check valves are free of debris and blockage.

  1. Open shutoff valve at tank and strainer.

  2. Fill tank with a minimum of 75 L (20 gal.) and check system for leaks

  3. IMPORTANT: Avoid excessive system pressure. Do not exceed maximum recommended rate for orifice or nozzle size.

    Refer to rate chart and set pump to maximum rate for the in-line orifice or nozzle that is installed.

  4. Lower machine to planting position and drive 90 meters (100 yards) at planting speed 9.7 km/h (6 mph.).

  5. Raise machine and turn fertilizer pump drive wheel by hand.

  6. Check all rows for liquid exiting the opener tubes in a steady stream. Repeat steps 2—5 until a steady flow of liquid is apparent at all openers and all air is flushed from distribution hoses.

  7. Select a target fertilizer rate from rate chart. Set pump range and install in-line orifices or nozzles for selected fertilizer rate.

  8. NOTE: As travel speed increases, the fertilizer system pressure also increases.

    Verify that system pressure is within 103—621 kPa (1.0—6.2 bar) (15—90 psi) when traveling at desired planting speed.

  9. If machine is stationary for a long period, air bubbles can develop and become trapped in the distribution hoses. Prime system as necessary.
