Testing the Breaker

Important:
After installing the breaker on a
machine, especially after storage, always test it
before you break material to release air from the
oil circuit. Using the breaker suddenly without
releasing the air breaks the oil film and causes
the breaker to seize.
1. Park the machine on a level surface and engage
the parking brake (if applicable).
2. Raise the loader arms and tilt the breaker so
that it is vertical. Ensure that the bit does not
touch the ground.
3. Slowly engage the forward hydraulics until the
breaker piston rises, then slowly reverse the
hydraulics before the piston impacts.
Important:
Do not allow the piston to
impact.
4. Refer to the table for testing times for the 2
stages.
Important:
Do not allow the piston to impact
during the air removal and seal recovery
time.
