WHEN DO I REPLACE. . .
a) Replace
the
cutter wheel
when deburring the key seems to take longer than normal. Replace
the cutter wheel when you find yourself “assisting” or “force-feeding” the carriage more
often, especially in deep cuts.
NOTE:
Rytan key machine cutter can be resharpened. Call us
for details.
b) Resharpen your cutters in sets. Store your old cutters until you’ve accumulated at least three
cutters – then call us about resharpening them to all the same size. When you have them all
resharpened to the same size you will have to readjust your key machine only ONCE for all
your resharpened cutters.
c) Replace your key machine’s
stylus
when you can see a worn spot such as a slight groove and/
or excessive rounding of the otherwise sharp stylus.
d) Replace
vise jaws
when the edges become rounded, flared, mushroomed or when you’ve cut
into them too many times.
e) Replace
the
key gauge shaft
when the key gauge shaft wobbles in the
carriage excessively.
f)
Replace
the
carriage shaft
and
bronze Oilite® bearings
when you can wobble them beyond
“just noticeable”.
g) Replace
the
drive belt
yearly if you use the machine a lot. Every 3-5 years if you have a low
volume shop.
h) Replace
the
cutter shaft
assembly when you hear a whirring, grinding or buzzing sound (do
not mistake the drive belt sound) or when you can feel any movement in the cutter shaft
assembly when you test it.
i)
Replace
the
power switch
if you accidentally bump it, or hit it, or drop something on it.
j)
Replace
the
power cord
when it begins to show signs of wear or cracking. If your machine is
5 years old or more you should consider replacing it just in case for safety reasons.
The Stylus
Unscrew the stylus lever. With the lever removed look 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.
