Turn the eyelet rod in the actuator rod to shorten
or lengthen the extended actuator to the desired
position (

Figure 64

).

Note:

You must turn the eyelet rod in half or

complete revolutions so that you can assemble
the rod to the boom.

7.

Once the desired position has been achieved,
tighten the jam nut to secure the actuator and
eyelet rod.

8.

Raise the boom to align the pivot with the
actuator rod.

9.

While holding the boom, insert the pin through
both boom pivot and actuator rod (

Figure 63

).

10.

With the pin in place, release the boom and
secure the pin with the cotter previously
removed.

11.

Repeat the procedure for each actuator rod
bearing, if necessary.

Cleaning

Cleaning the Flow Meter

Service Interval:

Every 200 hours/Yearly (whichever

comes first) (more often when using
wettable powders).

1.

Thoroughly rinse and drain the entire spraying
system.

2.

Remove the flow meter from the sprayer and
flush it with clean water.

3.

Remove the retainer ring on the upstream side
(

Figure 65

).

Clean the turbine and the turbine hub to remove
metal filings and any wettable powders.

5.

Inspect the turbine blades for wear.

Note:

Hold the turbine in your hand and spin

it. It should spin freely with very little drag. If it
does not, replace it.

6.

Assemble the flow meter.

7.

Use a low pressure (50 kPa or 5 psi) air jet to
ensure that the turbine spins freely.

Note:

If the turbine does not spin freely, loosen

the hex stud on the bottom of the turbine hub by
1/16 of a turn until it does spins freely.
