7.1.3 Rotors
Chemical reactions as well as stress-corrosion (combination of oscillating
pressure and chemical reaction) can affect or destroy the metals. Barely
detectable cracks on the surface can expand and weaken the material without
any visible signs.
•
Check the material regularly (at least once a month) for
−
cracks
−
visible damage of the surface
−
pressure marks
−
signs of corrosion
−
other changes.
•
Check the bores of the rotors.
•
Replace any damaged components immediately for your own safety.
•
Protect the rotors, lid seals, and rubber cushions (if included) at least once
per week with the supplied slushing oil (part no. 70104).
•
Grease the rotor tie-down screw after cleaning (grease for load-bearing bolts
part no. 70284).
