REMARK:
If you only wish to change the blades, only carry out points 1, 2, 4, 5 as well as
points 7, 8 and 9.
There is no need to dismantle the handle and reset the hand guard if you pull
back / bend the front area of the hand guard such that you can reach the retaining
rings and bolts.
CAUTION!
Don’t forget to apply LUKAS special grease to all sliding surfaces.
CAUTION!
The nut of the pivot bolt and the pivot bolt itself will be adapt together by a special
procedure, therefore they have only be changed as a set by usage of a new set!
Because of the special procedure an unscrewing of the nut while working will be
minimized and a resulting blade crack will be prevented.
The nuts can be unscrewed and thigtend up to 10 times without affecting the service
performance!
