A)
Scrape and clean shaft thoroughly (use emery tape). (Photo

B)
Use a dial caliper to determine where taper (if any) ends from
propeller hub. (Cutter cannot be mounted over taper.) MUST BE CLAMPED ON STRAIGHT SHAFT. (Photo #2) For acceptable
installation refer to Diagrams A, B & C here.
C) Also check shaft size. Shaft should measure .002 over nominal;
metric or oriental should be ordered to exact .001 (Photo #2).
D) In preparation for installation - disassemble cutter:
(1) Loosen stationary blade screws only 1/2 way out (screws #4
on Line and Net Cutter Assembly).
(2) Remove screws on rotating cutters.
