pressure hose is on the other side of the boom you
can cross the hoses or turn the hydraulic breaker.
Agree with the assistant on clear hand signals for use
during the mounting procedure.
2.
Carefully lower the stick of the boom into the adapter.
WARNING Moving parts can crush and cut
u Never check bores or passages with hands or fin-
gers.
An assistant must direct the movement of the boom
until the bores in the boom are flush with those in the
adapter.
3.
Insert the pin and lock.
4.
Lift up the hydraulic breaker using the boom.
5.
Extend the bucket cylinder until the bore in the toggle
is flush with those in the adapter. Insert toggle pin
and lock.
6.
After mounting the breaker, carefully extend and re-
tract the bucket cylinder to its full extent in each di-
rection. It is important that the cylinder can be fully
extended and retracted without any difficulty.
