Wear Limit
New Part
To increase the life of the lower bushing, remove the bushing after normal wear has devel-
oped and rotate the bushing 90° and lock into the second slot. Normal wear on the bushing
is usually found from front to back, by rotating the bushing 90° will add additional life to the
bushing. In addition to rotating the bushing, it is also symmetrical and can be ipped end
to end and again rotated 90° resulting in even longer life.
IMPORTANT
90° SLOT ROTATION
To increase the life of the tool stop, remove the tool stop after normal wear has developed
and rotate the tool stop 90° and lock into the second slot. Note: the tool stop is not sym-
metrical and can not be ipped from end to end.
