MOUNTING ON BASE MACHINE
WARNING
Two persons are necessary for mounting/dismounting the hydraulic breaker, so
determine signals for operation in advance.
Be sure to use a crane to handle brackets, pins, and other heavy objects.
When the pin retaining bolt is removed during operation, the mounting pin will come off,
and the hydraulic breaker will come off the hydraulic excavator, leading to injury or death.
CAUTION
When positioning pin holes, do not put your hand or finger in them, otherwise your hand
or finger may be cut off when the arm or hydraulic breaker moves.
1. Place the hydraulic breaker on timber. (Attach hoses and bushings.)
2. Move the base machine to align the hydraulic breaker with the arm. Lower the boom and align
the pin hole at the end of the arm with the pin hole in the bracket.
3. Insert a pin, install a stop ring, and attach a bolt.
