Original Instructions
6 Operation
NOTICE The hydraulic breaker or the working tool is not
to be used as a lifting device. When lifting heavy compo-
nents use the hook on the carrier arm.
6.1 Preparation before breaking
6.1.1 Operating temperatures
The operating temperatures of the hydraulic breaker are
between -20ºC (-4ºF) and +80ºC (+176ºF).
CAUTION Temperature hazard
The hydraulic breaker and the hydraulic oil system of the
carrier can be damaged if the hydraulic breaker is used
at higher or lower temperatures.
u Only start the hydraulic breaker when the hydraulic
oil has reached the proper operating temperature.
u If the ambient temperature is below –20ºC (-4ºF),
you must warm up the working tool and the hydraulic
breaker before use.
u
If the oil temperature e80ºC (+176ºF), you
must not use the hydraulic breaker as the oil quality
becomes inadequate which severely shortens the life
time of seals and O-rings.
6.1.2 Engine rpm
Too high engine rpm only results in increased fuel con-
sumption and increased oil temperature. Adapt the en-
gine rpm to the recommended value to give the correct
operating oil flow.
6.2 Operating
6.2.1 Risk area
Before starting the hydraulic breaker, make sure that no
persons are in the risk area, 20 meters (66 ft) both hori-
zontally and vertically from the hydraulic breaker.
20 m
6.2.2 Breaking
CAUTION Machine and tool hazard
Continuous operation at full extension and/or retraction
can result in damage to the hydraulic cylinders.
u Always avoid operating the breaker with the cylinders
fully extended or retracted.
u Reposition the carrier and/or boom to avoid fully ex-
tended or retracted cylinders.
u Pay attention and look at what you are doing.
Never start the hydraulic breaker until both carrier and
the hydraulic breaker are in the correct position.
n
Direct the hydraulic breaker in a position 90° towards
the object.
