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 flowmeter.
7. Use a low pressure (5 psi or 50 kPa) 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.
