G2790 Universal Knife Grinder -11-
7. Place the sliding support on the work plate
and turn the pivot adjustment knob until the
angle of the knife bevel is parallel to the
grinding surface.
8. Raise the grinding wheel, using the hand-
wheel at the back of the machine, until the
grinding surface makes contact with the
knife bevel. (The grinding wheel may need
to be lowered to accomplish Step 7.)
9. The grinding wheel should make consis-
tent contact with the knife across the entire
length of the bevel. Move the sliding sup-
port across the length of the knife. Adjust
the knife with the height adjustment knobs,
if necessary, to attain proper contact.
Make small adjustments and re-test
against the grinding wheel frequently to
make sure you don’t over-compensate.
10. Once you are sure you’ve made proper
bevel and alignment adjustments, lower
the grinding wheel slightly and turn on the
machine. Move the sliding support so the
knife is at the right hand side of the wheel.

11. Slowly raise the wheel until it lightly con-
tacts the knife bevel. Gently slide the knife
across the surface of the grinder. If contact
appears to be smooth and consistent
between the knife and the grinder, return
the sliding support to the right hand side of
the grinding wheel, raise the wheel slightly
and take a second pass. (A common
method for checking proper bevel angle is
to mark the entire surface of the knife’s
bevel with a permanent marker before
grinding. Once you make a pass over the
grinder, you can inspect the bevel to make
sure that the entire surface is being ground
evenly. If a portion of the bevel is not being
contacted, the ink will remain after the ini-
tial pass.)
As with the wider knives, proper adjustment for
chisels and other smaller cutting tools requires
that bevels and cutting edges be aligned square-
ly to the grinding surface. To adjust narrow-
edged tools:
1. Attach the stationary clamps to the pivot
plate.
2. Place your cutting tool between the clamps
and tighten the tool in place as shown in
Figure 7.
Use extreme caution when working near
cutting surfaces. Failure to exercise care
while working near knives could result in
severe injury.
