.
(2) Assemble X ring 21, O ring 23 and Fluoride ring 28 to Impact bolt as drawn in
Fig. 12.
Note:
1) If Fluoride ring 28 is worn, O ring 23 (orange) appears through Fluoride ring 28 on Impact bolt.
If so, be sure to replace O ring 23 together with Fluoride ring 28 and X ring 21 with new ones.
2) If there is dust in Tool holder, wash it off.
3) Once Fluoride ring 28 deforms, it does not shrink by itself. If installing it into Impact bolt
without the proper step, it may result in its breakage. So insert Impact bolt into Taper Sleeve (1R214)
for about 60 seconds to fit Fluoride ring 28 into the groove on Impact bolt.
