•There should be a .010-.020 gap (for roller clutch only) between the two clutch pieces.

•(Test on the solenoid test box.) The knife must cut both fabric and card stock. The solenoid should operate on both the high and low settings.

•Excessive motor drag must be minimal at start/stop and while running. Replace or repair problem component. On old knife assemblies, there are bronze bushings in outer support. They may be causing a bind. Ream bushing and retest. (Do not ream if it is a roller bearing.)

•(Rev 1) Pre-load setting adjustment. While motor is running, not while cutting, loosen set screws on “pac-man” and rotate the rotary blade clockwise, mark the stopping position on the “pac-man”, rotate counterclockwise, mark the “pac-man”, then rotate the blade to the middle of the two marks and tighten the set screws.

•(Rev 2) All new knife assemblies have a blue clutch. The clutch outer race bushing has an I.D. of .500 and the 2 extension springs are .012 dia wire.

•(Rev 2) The 2 extension springs on all rebuilt clutches must have the .009 dia. wire springs replaced with .012 wire springs.

•(Rev 5) Replace Knife Actuator 357020, if it is worn or if there is a “bulge” at the 90-degree bend.

•(Rev 6) Changed feeler gauge tolerance from .047 MIN
