    Spray Calibration/Tip Chart/Liquid Quantities The Z-Plug spray system comes standard with lavender colored Air Injected tips which will apply liquid material @ .32 (1/3) gallons per 1,000 sq. ft. @ 5 m.p.h and 4—45 psi. Each tip has a 5 psi shut-off screen to prevent drip.
  • Page 16 The Diffuser adjustment allows the user to adjust the intensity of the spread pattern. A small turn shifts the product placement on the impeller. This in turn balances the spread pattern heavier to the left (back side ramp) or heavier to the right (front side ramp). Adjustment is very sensitive, so multiple adjustments may be required.

  • Page 27: Trouble Shooting

    Troubleshooting Engine:  Not starting. There are a few reasons as to why your engine fails to start. If the engine does not turn over, then the battery could be dead, bad connection to the battery wires, key switch may be bad, 30 AMP fuse on the wiring harness (orange wire) may be blown or the starter solenoid may be bad (you will hear the starter solenoid trying to click on, but nothing is happening).
  • Page 28 Granular:  There are numerous potential challenges that can happen on the granular side due to the amount of use this portion of the unit sees. If product is not spreading evenly or consistently, then look for a few things with your hopper impeller or hopper diffuser.
  • Page 29 Charging Issues: 20 Amp Regulated Alternator The 20 amp regulated alternator system provides AC current through two output leads to the regulator-rectifier. The regulator-rectifier converts the AC current to DC, and regulates current to the battery. The charging rate will vary with engine RPM and temperature.
  • Page 30 DC Output Charging Wire Test A simple test can be used to test the DC output charging wire circuit. If a wiring problem exists it can be corrected before testing regulator-rectifier. Leave stator wire harness disconnected from regulator-rectifier. Equipment key switch must be in OFF position.
