My propeller speed is turning real slow and won’t increase speed when I turn the knob. The knob wasn’t turning at first and I stayed WD 40 on the cable. The knob was not at first turning but eventually did, but the speed didn’t increase. Did I break something?

A slow propeller speed that does not increase when adjusting the knob on an L.T. Rich Products Z-Spray could be caused by air in the hydraulic system, a loose impeller, or issues with the hydraulic hopper motor.

Other high-quality detergent oil are acceptable if classified for service SF, SG, SH, SJ or higher. Do not use special additives. Outdoor temperatures determine the proper oil viscosity for the engine. Use the chart to select the best viscosity for the outdoor temperature range expected.

    (depending on your water source, not draining the water out of the system and storing the Z-Spray dry can create algae build up).

  • Page 11: Spreader System Maintenance

    Attachment Maintenance The Z-Spray can be equipped with a few of the L T Rich Products attachments. These available attachments include an 7 gallon auxiliary tank, 30 gallon specialty tank, Isolated Tank or a 1 gallon Foam Marking Kit.

  • Page 12: Overview

    This attachment is used mostly for your NON-TURF friendly products such as Round Up and other total kill products, but can also be used for selective products. ~ Foam Marking Kit (part # 80907-60 or 80930-Foam) – This attachment allows a unit to mark the turf and make the operator aware of where the product was just applied.

  • Page 13: Operation

    ~Spreader – The Z-Spray units are equipped with a 220 lb. or 120 lb. spreader. The hydraulic hopper motor with the spreader control rate knob allows variable spread widths from 3 to 25 feet.

  • Page 14: Spray/Spreader System Page

    Using the spreader system, there are 3 cables to operate the hopper door (far left cable), the diffuser (middle cable) and the deflector shield (lower right cable). By pulling on the far left hopper door cable, this will open the door and allow product to fall on the spinner. Adjustments as to how wide the door opens are made on the front on the hopper with the Hopper Rate Dial (Ref # 37 on page 17).

  • Page 15: Spray Calibration/Tip Chart/Liquid Quantities

    (Hose reel Chrome Valve in open position) Spray Calibration/Tip Chart/Liquid Quantities The Z-Spray liquid system comes standard with lavender colored Air Injected tips which will apply liquid material @ .34 (1/3) gallons per 1,000 sq. ft. @ 5 mph and 40 psi. Each tip has a 5 psi shut-off screen to prevent drip.

  • Page 16: Spreader Calibration/Layout

    Your machine is capable of using tips from ¼ to 1 gallon in size. See chart for your desired drop rate. The following are some general guidelines for sprayer calibration (Note: this chart only applies if using Air Injected tips. Using other tips will require different calculations). Please refer to the spray chart provided for complete calibration (spray charts are now located on the backside of the knee pad for quick in the field reference).

  • Page 31: Troubleshooting

    SECTION 7 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 32 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 33 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 34 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.
