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 the
N
EUTRAL
position.
•
For the HDX-Auto model —shift the
transmission to P (park).
4. Engage the parking brake and turn the engine
on.
5. Turn on the sprayer pump.
6. Set the engine speed as follows:
•
For machines without the optional throttle
lock—have 1 person press down on the
accelerator pedal until the engine reaches
maximum speed.
Note:
Have the other person collect
samples from the sprayer nozzles.
•
For machines with the optional throttle lock,
press down on the accelerator pedal until the
engine reaches maximum speed and set the
throttle lock; refer to operation instructions
for your Workman hand throttle kit.
7. Set the 3 individual boom valves to the O
FF
position.
8. Set the master boom switch to the O
N
position.
9. Set the system pressure to Maximum.
10. Press the agitation switch to the O
FF
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 89 )
on the backside of the agitation valve until the
pressure reading on the gauge is 6.9 bar (100
psi).
