Hydraulic Breaker
¡ Do not pound with the cylinder fully
extended or contracted (at the stroke end).
Leave a margin of at least 5 cm.
¡ Do not pound with the arm perpendicular
to the ground surface.
¡ Do not drop the breaker itself on the object
to be broken in order to break it.
¡ Do not move objects to be broken or rocks
with the breaker itself.
¡ Slew occasionally to cool the engine.
¡ If a hydraulic hose is vibrating abnormally,
nitrogen gas may be leaking from the
accumulator. Have an inspection as soon
as possible.
Replace the hydraulic oil
regularly!
¡ When using a hydraulic breaker, the oil
deteriorates quicker than during normal
digging. Be sure to replace the hydraulic
oil and return filter element.
• Failure to replace these in time can lead
to damage to the machine and breaker's
hydraulic systems. In order to improve
the service life of the hydraulic systems,
be sure to replace the hydraulic oil and
return filter element according to the
following chart of the replacement
interval.
• Clean the suction strainer when
changing the return filter element.
