Check if the gauge's hole (A) can be pushed down
●
on the insertion tool's shank, this means that the
shank is worn out and the insertion tool should be
replaced.
● Check the length (B), that it is according to the
ordered machine type.
Fitting and removing the insertion tool
Whenever fitting or removing the insertion tool the
following instructions must be observed:
1. To prevent an accidental start: switch off the
power supply and bleed the machine by pressing
the start and stop device. Disconnect the
machine from the power source.
2. Before inserting a tool, lubricate the tool shank
with grease.
3. Fit or remove the insertion tool.
4. Close the tool retainer (position A) and check the
lock function by tugging the inserted tool sharply
outwards.

Safety and operating instructions
Start and stop
Start
Check that the tool is in good order and pressed
●
fully home in the nose of the breaker.
● Check that the latch is locked, so that the tool does
not fall out.
Remove the protective caps from the quick-release
●
couplings.
Clean the quick-release couplings if needed and
●
connect the tail-hoses to the extension hoses of
the power source.
● Place the breaker at a right angle on the material
to be broken and activate the trigger lever.
Stop
● Release the trigger. Press the breaker against the
surface, until the breaker has stopped completely.
Stop the power source.
●
Disconnect the hoses and fit the protective caps
●
to the quick-release couplings.
Operating
Preparation before starting
The following checks should be made each time you
start to use the breaker. All these checks concern
the serviceability of the breaker. Some concern your
safety:
♦ Clean all safety stickers. Replace any that are
missing or cannot be read.
♦ Inspect the hoses generally for signs of damage.
♦ Inspect the working tool for wear and damage. Do
not use an excessively worn or damaged tool.
♦ Connect the tool.
♦ Ensure that the hydraulic couplings are clean and
fully serviceable.
♦ Never invert the breaker without first isolating it
from the power source. The working tool might be
ejected violently while connecting it, if the breaker
is connected to the power source.
♦ Ensure that any power source you plan to use is
compatible with the breaker model used (see the
"Technical data"). Use the recommended oil flow
divider, if the flow from the power source can
exceed the maximum allowed oil flow.
♦ Never exceed the maximum relief valve setting
stated on the tool.
