the most accurate measurement.
Note:
Calibration is now complete.
Calibrating the
Section-Bypass Valves
Before using the sprayer for the first time, whenever
you change the nozzles, or as needed, calibrate the
sprayer flow, speed, and set the section bypass.
Important:
Select an open flat area to perform
this procedure.
Note:
Calibrating the section bypass for
machines
without a throttle lock
requires 2 people.
Preparing the Machine
1.
Ensure that the sprayer tank is filled with water.
2.
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).
3.
Engage the parking brake and turn the engine
on.
4.
Set the 3 section switches to the O
N
position,
but leave the master-section switch in the O
FF
position.
5.
Set the pump switch to the O
N
position, and turn
on the agitation.
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 engine speed.
Note:
Have the other person adjust the
section-bypass valves.
•
For machines
with
the optional throttle lock,
press down on the accelerator pedal until
the engine reaches maximum engine speed
and set the throttle lock; refer to operation
instructions for your Workman hand throttle
kit.
7.
On the InfoCenter, navigate to the Calibration
menu and select Test Speed.
Note:
Selecting the Home Screen icon at any
time cancels calibration.
8.
Using the plus (+) and minus (–) symbols, enter
a test speed of 5.6 km/h (3.5 mph), then select
the Home icon.
