7. Clean the brake pin and install it in the shaft at the center of the
stator. The pin should move freely up and down in the stator
shaft.
8. To reassemble the stator and pin, align the screw holes then lower
the stator and pin into place. The slot on the end of the stator
must straddle the brake spring in the hole as shown in Figure 5-4.
(The wire direction is indicated by an imaginary line between the
stator screws.) Press the stator down firmly. The brake pin will
bounce up about 3 mm (
pin to test its motion.
9. Replace the screws. Firmly tighten the screws, alternating until
both are tight.
10. Place the stator pad on the channel of the stator.
11. Reconnect the power cord.
12. To reconnect the air supply, pull back the spring-loaded sleeve of
the quick-disconnect hose and push the sleeve over the fitting at
the rear of the instrument.
• Periodically lubricate the threads of the pressure regulator knob
with Spinkote lubricant (306812).
• Lightly coat the three stator O-rings with silicone vacuum grease
(335148) when removed for stator cleaning.
Expected service life of the filter element is approximately
1400 hours of run time, if the air supply is not excessively oily.
Replace the element when it turns red or when there is an additional
drop of about 67 kPa (10 psig) in the air pressure that reaches the
Airfuge. Instructions for replacing the element are in the Filter
Element Kit (878587).
