Inspection

WARNING: Do not operate engine until fan has first been inspected for cracks and/or separations. If a fan blade is found to be bent or damaged in any way, do not attempt to repair or reuse damaged part. Proper balance is essential in fan assembly operation. Balance cannot be assured once a fan assembly has been found to be bent or damaged and failure may occur during operation, creating an extremely dangerous condition. Always replace damaged fan assembly.

Place fan on flat surface with leading edge facing down. If there is a clearance between fan blade touching surface and opposite blade of more than .090 inch (2 mm), replace fan.
