resharpened to the same size you will have to readjust your key machine only ONCE fo

The Stylus
Unscrew the stylus lever. With the lever removed l
ook inside the hole- there is a #10-32 Allen set /32”
Allen Hex Wrench to loosen the screw about 1 full turn the “disk” will snap back to the back edge of
the slot. Gently pull out the stylus and reinstall a new one. With a pair of small screwdrivers gently
push the “disk” forward to about halfway in the slot. Push hard on the tip of the new stylus to make
sure it didn’t come forward when you worked the disk forward. Tighten the disk onto the stylus-be
absolutely certain that the setscrew in the disk is locating directly on the flat on the stylus. Refer to
depth Adjustment section in this manual.
The Cutter Shaft
Remove the left-hand nut and cutter wheel. Remove the access plate and wire brush if installed on
your RY256. Loosen the drive belt tension idler and remove the drive belt. Loosen the two
cap screws located on the top front edge of the cutter head – use your 3/16” Allen Hex wrench.
Loosen them about 1 full turn each.
Pull out the entire cutter shaft assembly and replace with a new one. Reassemble in the reverse
order from above. Refer to cutter Wheel Central Adj. Section in this manual.
