2.  Remove the blade holder assembly from the cutoff assembly by depressing the detent lever and 

turning crank until holder is completely un-threaded. Replace standard blade holder with extended 
blade holder by turning blade holder by hand until the groove in the holder aligns with the guide pin. 
Then depress detent lever and turn crank until holder is completely threaded into assembly.
