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. If it does not, loosen
the hex stud on the bottom of the turbine hub by
1/16 of a turn until the turbine spins freely.

Cleaning the Suction Strainer

Service Interval: Before each use or daily (more often
when using wetable powders)
