because of one piece construction no
pre-setting of the tooth is required.
Make sure teeth are placed in
coordinance with wheel rotation.
' After setting each tooth pair, tighten the
socket head bolts to 135 to 145 foot-
pounds.
NOTICE:
Do not hammer the tip of a tooth. Due to the su-

chip from such treatment.

A 'left', a 'straight' and a 'right' tooth is determined by
which direction the tip of the tooth points. The left and
right sides of the cutting wheel correspond to the left
and right sides of the machine itself. (For a review of
the machine orientation see the '

Sharpening of Teeth
Do not allow any tooth to wear too much before
sharpening. Discard any tooth that has lost more than
1
/
8
" of original bite.
The teeth must be removed from the cutting wheel for
proper sharpening.
NOTICE
Sharpening cemented carbide cutting teeth
requires a special process. Have your teeth
sharpened only by a qualified machinist for
obtaining a proper edge and to avoid injury.
Tooth Sharpening Guidelines
1. Obtain an unused tooth for comparison.
2. Discard any tooth that has lost more than
1
/
8
" of
original bite, whether lost through usage or
grinding.
3. Grind off minimal amount from end, just enough
to restore the original taper and radius on end.
The end of the cemented carbide tip and the
end of the steel shank should be flush after
grinding.
