11. Turn on the left boom and turn off the right boom.
12. Adjust the right boom bypass valve ( Figure 74 )
until the pressure reading is at the previously
adjusted level (typically 40 psi or 2.75 bar).
13. Turn on the right boom and turn off the center
boom.
14. Adjust the center boom bypass valve ( Figure 74 )
until the pressure reading is at the previously
adjusted level (typically 40 psi or 2.75 bar).
15. Turn all the booms off.
16. Turn the pump off.
Note:
Calibration is now complete.

Calibrating the Agitation Bypass
Valve
Service Interval: Yearly
Important:
Select an open flat area to perform
this procedure.
Note:
Calibrating the agitation bypass valve for
machines without a throttle lock requires 2 people.
1. Ensure that the sprayer tank is filled with water.
2. Verify the agitation control valve is open. If it has
been adjusted, open it completely at this time.
3. Set the transmission as follows:
•
For HD-Series Models with a manual
transmission —shift the transmission to
Neutral
•
For the HDX-Auto model —shift the
transmission to P (park).
4. Set the parking brake and turn the engine on.
5. Set the
PUMP
switch to the On position.
6. Set the engine speed as follows:
•
For machines without the optional throttle
lock—have 1 person press down on the
accelerator pedal until maximum engine
speed is reached.
Note:
The other person will collect samples
from the sprayer nozzles.
•
For machines with the optional throttle
lock, press down on the accelerator pedal
until maximum engine speed is reached
and set the throttle lock; refer to operation
instructions for your Workman hand throttle
kit.
7. Set the 3 individual boom valves to the Off
position.
8. Set the
MASTER BOOM
switch to the On position.
9. Set the system pressure to Maximum.
10. Press the
AGITATION
switch to the Off position
and read the pressure gauge.
•
If the reading remains at 6.9 bar (100 psi) the
agitation bypass valve is properly calibrated.
•
If the pressure gauge reads differently
continue to the next step.
11. Adjust the agitation bypass valve ( Figure 76 )
on the backside of the agitation valve until the
pressure reading on the gauge is 6.9 bar (100
psi).
