MAINTENANCE STONE SHARPENER CONTINUED
PROPER ADJUSTMENTS
OF SHARPENER
Proper adjustment and maintenance of the
sharpener gives longer and better knife ser
vice. If the sharpener doesn't operate properly
and tends to grind more on one side of the
knife than the other, first check to be sure that
the grinding wheels are not dirty or worn. If the
parts are dirty, clean them thoroughly. Check
the bottom belt (#2 on page 8) for proper ten
sion and wear by comparing it with a new belt.
If this doesn't remedy the situation it can
be corrected by adjusting the emerys. To
check the grinder adjustment, remove the cap
and spring (#3 on page 8) from the tension
assembly. With the machine running, operate
the sharpener and observe from the rear of
the machine, the position of the grinding
wheels relative to the knife or standard.
To adjust the emery wheel balance of the
sharpener, first back out the balance screw
(#3 on page 1) and, while running the sharp
ener with tension cap removed, observe the
location of the emery wheels in relationship to
the knife. The gap between the wheel and the
knife will be greater on the side of the knife far
thest from the adjusting screw. Next, very
slowly, 1/8 turn at a time, tighten the balancing
screw. The gap on the balance spring side will
slowly close. When gap on both sides of knife
is same, reassemble the tension cap assem
bly (Fig. E). Do not tighten balance screw
more than required to equalize wheel to knife
gap on both sides. The emery wheel balancer
can also be adjusted by examining the sharp
ener of the blade. If the side of the blade far
thest -from the balance adjusting screw is
being ground too much, tighten the screw until
an even grind on both sides is achieved. If the
side of the blade closest to the adjusting
screw is ground to much, the balance
adjusting screw should be loosened slightly.
Note: If the sharpener doesn't operate
properly after all of the above steps have
been taken, it is probable that #1271100 Fibre

When properly set, the
grinding wheels are cen
tered with the same dis
tance between the knife
and grinding wheel on
each side. If only one
wheel is grinding, deter
mine which wheel it is
and
then
stop
the
machine.
@
Be sure to remove tension
cap before attempting to
adjust sharpener.
Below shows the proper reassembly of the
tension adjustment spring components.
Since the grinding wheels will not be cen
tered when the machine is not operating, it
must be running when checking adjust
ment.
