7.0 Care and Maintenance – [cont’d]
CAUTION
Injury from flying debris. Personal
protection equipment is required when
operating this equipment. PPE must
include safety eyewear and hearing
protection.
Prolonged exposure to high noise levels
may cause hearing impairment or loss.
Hearing protection must be worn when
breaker is in operation.
CAUTION
Clear out all personnel before
maneuvering the carrier into the work
area.
Injury form flying debris. Do not
operate breaker with personnel in
vicinity of work zone.
CAUTION
Injury from flying debris. Proper
guarding must be fitted to the
operator’s cab when the breaker is
used.

7.10.2 How to Measure the Oil Pressure
IMPORTANT
Serious equipment damage may result if proper
procedures are not followed. Diminished service life
will result if attention to correct machine set up is
ignored.
Certain tests, such as measuring the oil pressure,
can only be done while the breaker is operating.
Lower the Breaker to the ground and stop the
carrier engine.
CAUTION
Follow all safety and operating
instructions provided by the carrier
manufacturer. Engage interlock, shut off
engine and apply parking brake.
Relieve hydraulic pressure inside breaker and
attachment circuit.
Connect a pressure gauge [0-5000 PSI] to the
measuring port located at the [IN] side of the
breaker.
Use the form provided in Section 14.2 to record
your results.
Start the carrier. Use the boom and arm controls
to extend the breaker away from the carrier.
Position the breaker tool against the steel plate.
Do not drop breaker on to the plate.
Adjust the engine's rpm to the normal operating
speed and set operating mode to "breaker".
The test can begin when the normal operating
temperature is reached.
Start the breaker and record the pressure
reading. It's normal for the needle of the gauge to
pulsate so use the average pressure. Compare
your results with the values listed in the Technical
Data Section of this manual.
When the pressure-measuring test is complete,
lower the breaker into a safe position and stop
the engine. Remove test gauge and reinstall plug.
CAUTION
Hydraulic circuits differ between
machines. Improper oil flow or pressure
can damage the breaker or carrier.
Only qualified personnel, having knowledge of the
machine’s systems, proper test equipment and tools
should perform conversion set-up and adjustments.
