LOWER BUSHING
To increase the life of the lower bushing, remove the bushing after normal wear has
developed, rotate the bushing 90° and lock into the second slot. Normal wear on the
bushing is usually found from front to back. Rotating the bushing 90° will add additional life
to the bushing. In addition to rotating the bushing, it is also symmetrical and can be flipped
end to end and again rotated 90° resulting in even longer life.
TOOL STOP
To increase the life of the tool stop, remove the tool stop after normal wear has developed,
rotate the tool stop 90° and lock into the second slot.
Note: The tool stop is not symmetrical and can not be flipped from end to end.
