parking brake, shut off the pump, shut off the
engine, and remove the key.
2. Extend the booms to the spray position and
support the booms using stands or straps from
a lift.
3. With the weight of the boom supported, remove
the bolt and nut securing the pivot pin to the
boom assembly (

4. 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.
