Note 1) When inserting Tool holder A, use care that O ring36 mounted on
tool holder A may not exceed the hole for holding the pin 10 of tool holder B.
(Reason : O ring 36 may be cut off.)
Note 2) O ring 36(Pn:213522*3) to be mounted on the Tool holder A is different
from the O ring 36(Pn:213510*0) to be mounted on Cylinder 40 and crank
cap.
O ring to be mounted on Tool holder A is the one of heat resistanse
and is coated with green paint for identification.
