(5) Remove nozzles (2) from rotary atomizers (3) and install nozzles (2) on pesticide hose (1).
(6) Place both fittings with nozzles in graduated container.
(7) Set key on engine to ON.
(8) Start engine with ENGINE START switch.
Note time before performing step (9) since application rate can only be determined if
dispersal time is known. During ground test, 30-minute operating time should not be
exceeded; overheating and damage to equipment will occur.
(9) Note time and calculate desired flow rate in accordance with pesticide label instructions and the following
(a) Set SYSTEM switch to ON. Check for hydraulic leaks, that EMPTY indicator is not lit, and that
pressure gage on secondary hydraulic manifold assembly indicates 300 psi.
(b) Press DISPERSAL pushbutton. After pre-determined time is up, release DISPERSAL pushbutton and
set SYSTEM switch to OFF.
(c) Measure amount of pesticide collected in bucket and calculate application rate (para 2-10, f). If
application rate is incorrect, proceed with step (10). If application rate is correct, proceed with step (12).
Loosen jam nut on primary manifold adjustment knob and adjust manifold pressure. Tighten jam nut.
Repeat steps (9) and (10) until application rate is correct.
Do not run system longer than 3 minutes after EMPTY indicator lights, or damage to
pump could occur.
When application rate is correct, or if EMPTY indicator lights, set SYSTEM switch to OFF, POWER
switch to OFF, and key on engine to OFF.
SD System Operational Test. This test consists of verifying PDU function and final adjustment of application
rate. Sample flow rates using Agrisect pesticide are given in table 2-6.
