4. Clean and lubricate the bushing plentifully.
NOTICE When mounting a new working tool, it
is especially important to lubricate plentifully.
5. Mount the working tool, use a lifting strap to
reduce the risk of personal injury.
6. Rotate the working tool to spread the grease.
7. Mount the tool retainers, one at the time.
8. Drive in the lock pin until the lock buffer attaches
in the lock pin groove.
Operation
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.
