OPERATING INSTRUCTIONS (Continued)
GRINDING THE TOP FACE
NOTE: The following instructions presume that you
have already studied "General Operating
Information" starting on Page 11.
Loosen the thumbscrew on the wheel guard and rotate
to the rear and lock in place.
If you want to match the exsisting angle, place the
Angle Finder on the bedknife as shown in FIG.
Read the angle indicated on the magnetic bubble
indicator to which the bedknife is mounted. Then place
the bubble indicator on top of the motorhead as shown
in FIG. 22.
Adjust the motor head until it is positioned at the same
angle as the bedknife face. You have now matched the
motorhead angle to the top face of the bedknife.
THE HEAD IS HEAVY AND MUST
BE SUPPORTED WHEN THE
LOCK IS RELEASED.
NOTE: The bedknife may have been excessively
adjusted and lapped since its last grind. In these
cases, establish the bedknife angle from the small top
surface outside the wear area as shown in FIG. 21A.
If you want to set the angle to the manufacturer's
specifications, measure the mounting surface angle at
the top or bottom of the bedknife as shown in FIG. 21B
and then get the correct working angle from page 21 of
this manual. Then add or subtract the relief angle to
determine the grinding wheel angle.
When you have the motor head angle set, adjust the
motorhead protractor angle scale to 0 degrees. See
FIG. 24.
Handcrank the vertical feed adjustment knobs and
move the horizontal adjustment until grinding wheel just
touches the face of the bedknife and covers the surface
to be ground. At this point the grinding wheel rim is to
extend over the bedknife top surface being ground by
1/2" whenever possible. See FIG. 23.
f the grinding wheel rim does not
I
extend over the bedknife face, it will
wear unevenly and cause grooves
across the surface of bedknife.
When the grinding wheel cannot extend over the
bedknife surface, dress the grinding wheel more
often.
21A.
If you don't have the optional angle finder, you will
have to adjust the grinding head angle to match
the bedknife angle by visually matching the wheel
angle to the bedknife angle.
For final adjustments, turn the GRINDING WHEEL
switch OFF and manually touch the wheel to the
bedknife top face to where it is contacting. Look
at the scratch marks to determine that they go fully
across the bedknife face. If not, adjust the angle
of the motor head until they match.
