5.2 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.
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).

The throttle valve adjusts pressure. The throttle valve is located just before the return
valves near the left side control panel. Turn clockwise to increase pressure, counter
clockwise to decrease pressure. Pressure will be displayed on the gauge bear the control
panel. Once the nozzles are opened, you will notice a slight decrease in pressure (adjust
accordingly).
To determine liquid quantities per tank, understand what tips you have on your machine
(factory set is 1/3 gallon per 1,000 sq. ft. through the Lavender tips). For instance some
products call for 1.1 to 1.5 oz per 1,000 sq. ft. We would recommend using 1.3 (median
value of 1.1 to 1.5). Since you are using a 1/3-gallon tip, you need to multiply by 3, then
multiply that number of gallons you need to put in your tank.
1.3 (median value of 1.1 to 1.5) X 3 (1/3 gallon tips) X gallons needed. If you were filling
an 18-gallon tank your equation would look like this:
1.3 X 3 X 30 = 117 ounces of product in 30 gallons of water.
5.3 Spreader Calibration/Layout
The Spreader Motor Control determines the speed of the impeller in the front on the
machine. The control is numbered 1-10; these numbers are used for points of reference.
Your machine is capable of varying its spread pattern from 4 – 25 feet with this control.
Being hydraulically driven, the spread pattern is independent of the ground speed.
The hopper control cable opens and closes the door inside the base of the hopper. The
maximum size of the opening will be determined by the rate adjustment on the knob dial.
This will set your rate gate linkage bar to limit and stop the rate the door can open.
