If front shield or dust cover is worn out, change to
new ones, otherwise reuse them.
Mount the front shield and dust cover on the
working tool. Mount the working tool in accordance
with step 4 - 8.
Operation
NOTICE The hydraulic breaker or the working
tool is not to be used as a lifting device. When
lifting heavy components use the hook on the
carrier arm.
Preparation before breaking
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.
►
Only start the hydraulic breaker when the
hydraulic oil has reached the proper operating
temperature.
►
If the ambient temperature is below –20ºC
(-4ºF), you must warm up the working tool and
the hydraulic breaker before use.
►
If the oil temperature exceeds +80ºC (+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.
Engine rpm
Too high engine rpm only results in increased fuel
consumption and increased oil temperature. Adapt
the engine rpm to the recommended value to give
the correct operating oil flow.
Operating
Risk area
Before starting the hydraulic breaker, make sure
that no persons are in the risk area, 20 meters
both horizontally and vertically from the hydraulic
breaker.
Breaking
CAUTION Machine and tool hazard
Continuous operation at full extension and/or
retraction can result in damage to the hydraulic
cylinders.
►
Always avoid operating the breaker with the
cylinders fully extended or retracted.
►
Reposition the carrier and/or boom to avoid fully
extended or retracted cylinders.
►
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.
◆
Direct the hydraulic breaker in a position 90°
towards the object.
◆
Start near the edge and work your way in
towards the middle. Never start in the middle of
large objects.
