Clean in-line orifices or nozzles or increase in-line orifice size or nozzle size per rate chart.

Excessive drive tire slippage

Reduce row unit down force. Check drive for misalignment or binding.

Plugged strainer.

Clean strainer.

Kinked delivery hose at wings or at row.

Fix or replace pinched hose.

Drive tire or contact tire pressure low.

Inflate to proper pressure.

Inspect check valves. Clean or replace as necessary.

System pressure is too low.

Verify system in between 103—621 kPa (1.0—6.2 bar) (15—90 psi). If low, then install smaller in-line orifices or increase travel speed.

Incorrect hose routing.

Verify there are no large hills or valleys in fertilizer distribution hose routing.

System not primed correctly.

Prime system and make sure that all air is purged from distribution hoses.

Some fertilizer hoses are pinched.

Fix or replace pinched hoses.

Different size in-line orifices or nozzles installed at each row.

Verify all in-line orifices or nozzles are the same size.

Increase the amount of down force on the opener. Lower the depth setting of the opener.

Install heavy spring.

Reduce the amount of down force on the opener. Raise the depth setting of the opener.

Install light spring.

Replace or reassemble check valve.

Fertilizer tube opener spout plugged.

Inspect, clean, and remove obstruction.

Manifold pressure too low.

Use smaller in-line orifices or nozzles to increase pressure to between 103—621 kPa (1.0—6.2 bar) (15—90 psi) Add gauge to monitor pressure.

Drive tire or contact tire pressure low.

Inflate to proper pressure.

Distribution hose pinched, preventing flow to opener.

Reroute hose.

Verify system pressure is between 103—621 kPa (1.0—6.2 bar) (15—90 psi). If high, then reduce ground speed or increase in-line orifice size.

Tubing in not fully pushed in.

Push tubing into coupler so it is fully inserted.

Tubing is not squarely cut or is not chamfered.

Remove tubing, squarely cut and chamfer before re-inserting into coupler.

In-line orifice outer surface is scored.

Replace in-line orifice.

O-ring is damaged or missing in coupler.

Replace coupler.
