Choosing working tool

A correct working tool is a prerequisite for good
operation. To avoid unnecessary machine damage,
it is important to choose working tools of a high
quality.
Recommended working tools are listed in the
machine´s spare parts list.
The narrow chisel should be used for demolition and
cutting work in concrete and other types of hard material.
The moil point should only be used for creating holes in
concrete and other types of hard material.
The wide chisel should be used in soft materials e.g.
asphalt and frozen ground.
Always use a sharp tool to be able to work effectively.
A worn out tool causes increased vibrations and the
operation will take longer.

Safety and operating instructions

Checking for wear

Using a working tool with a worn out shank
leads to increased machine vibrations. To avoid
increased vibrations, check the shank for wear
before the working tool is fitted in the machine.
Use the gauge that corresponds to the working
tool's shank dimension. If the gauge's hole (2) can
be pushed down on the working tool's shank, this
means that the shank is worn out and the working
tool should be replaced.

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.
