Rockbreaker
General
WARNING The attachment will move when released. Stand clear and to one side when releasing the
attachment.
WARNING The rockbreaker must be positioned correctly before attempting to release it from the quickhitch.
if incorrectly positioned, the rockbreaker could swing or fall suddenly from the machine when releasing the
quickhitch latch hook.
WARNING Always install the quickhitch latch hook locking pin (mechanical only). Failure to install the pin
will result in possible failure of the latching mechanism. Such a failure would result in the sudden release of
an attachment from the machine and you or others could be killed or seriously injured.
To prevent premature wear, failure and breakage, the Quickhitch assembly must be used with a rockbreaker
for short periods only. If the machine is to be used for rock breaking for a long period of time, it is recommended
that the rockbreaker is installed directly on the machine.
When using a rockbreaker, it must be curled towards the machine (as a typical digging operation).
Do not use the rockbreaker as a lever as this causes excessive loads on the locking mechanism.
Installation
1. Set the rockbreaker on solid, level ground. Use safe and correct lifting equipment to move bucket.
2. Position the machine.
3. Use the excavator controls to engage the jaw of the Quickhitch with the pivot pin of the breaker.
4. Use the excavator controls to roll the Quickhitch in until the latch hook has fully engaged the pivot pin on
the breaker. It may be necessary to apply a load to achieve Quickhitch connection. Alternatively, use the
tommy bar to lever the latch off, allowing the breaker pivot pin to locate in jaw of the Quickhitch.
WARNING! Make sure that the latch hook has fully engaged, otherwise the attachment could fall and you
could be killed or injured
5. Install the latch hook locking pin and secure with the lynch pin.
Removal
1. When possible, put the Quickhitch attachments on solid, level ground to make the installation procedure
safe and easier.
2. Park the machine on solid, level ground.
3. Position the rockbreaker just clear of the ground and at an angle such that the rockbreaker does not detach
from the front pivot pin when the Quickhitch is unlatched.
Figure 90.
4. Stop the engine.
5. Turn the ignition key to position 1.
