Turn the knob of the throttle valve counterclockwise
to decrease spray-system pressure (
Figure 42 ).
Sprayer-system pressure displays on the pressure
gauge (
Figure 43 ). When the spray nozzles are open,
sprayer-system pressure decreases slightly; adjust
throttle valve to compensate for the drop in pressure.

Mixing Product
Calculating the Average Application Rate
To determine about of product to mix for solution of
chemical in the tank, you need to understand what
nozzle application rate of your machine (the factory
installed lavender nozzle tip application rate is 1.3
L/93 m
2 (1 / 3 gallon per 1,000 ft 2 ).
For example, a product may specify an application
rate range of 33 to 44 ml/93 m
2 (1.1 to 1.5 oz per 1,000
ft 2 ). When calibrating the sprayer, use the formula that
follows to calculate the average application rate:
Average Application Rate Formula
[lowest application rate] +
[highest application rate] = [sum rate]
[sum rate] / 2
= average application rate
Example: 33 + 44 ml (1.1 + 1.5 oz) = [77 ml (2.6 oz)
sum rate]; 77 ml / 2 (2.6 oz / 2) =38.5 ml/93 m 2 (1.3 oz
per 1,000 ft 2 )―the average application rate value
Calculating the Amount of Product for a
Solution of Chemical
1. Multiply the average product application rate by
the 1-gallon nozzle tip factor to determine the
1-gallon application rate.
Example: median application rate value—38
ml/93 m 2 (1.3 fl oz per 1,000 ft 2 ) of 1.1 to 1.5) x
3 (lavender nozzle tip—nozzle tip factor) = 3.9
(adjusted application rate)
2. Multiply the 1-gallon application rate by the
amount of chemical solution that you need to
add to the spray tank.
Example: 3.9 (adjusted application rate) x
gallons needed. If you are preparing a 114 L (30
US gallon) solution of chemical, use 3.5 L (117 fl
oz) of product (3.9 x 30) for 114 L (30 US gallon)
of water.
