2. R otate the opposite ends of the blades forw ard.
3. Measure from a lev el surface to the cutting
edg e of the blades at the same position as in
ste p 1 abo v e .
T he difference betw een the dimensions
obtained in ste ps 1 and 2 m ust not ex ceed
1/8 inc h (3 mm). If this dimension ex ceeds
1/8 inc h (3 mm), the blade is bent and m ust
