Working tool
CAUTION Hot working tool
The tip of the working tool can become hot and
sharp when used. Touching it can lead to burns
and cuts.
►
Never touch a hot or sharp working tool.

Wait until the working tool has cooled down
before carrying out maintenance work.
NOTICE Never cool a hot working tool in water, it
can result in brittleness and early failure.
Selecting the correct working tool
Selecting the correct working tool is a precondition
for proper machine function. It is important to
select a high quality working tool to avoid
unnecessary machine damage.
Never use a working tool without a collar. Always
use the correct working tool.
NOTICE Never use the machine directly on
spikes or tent poles.
Recommended working tools are listed in the
machine's spare parts list.

WARNING Vibration hazard
Using inserted tools that do not fulfil the criteria
mentioned below, will result in a longer time to
complete a task, and may result in higher levels of
vibration exposure. A worn tool will also cause
increased working time.
►
Make sure that the inserted tool is well-
maintained, not worn out and of the proper size.
►
Always use a sharp tool in order to work
efficiently.
Checking for wear on the tool shank
Use the gauge that corresponds to the working
tool’s shank dimension. See section "Technical
data" for correct tool shank dimensions.
•
Check if the gauge’s hole (A) can be pushed
down on the working tool’s shank, this means
that the shank is worn out and that the tool
should be replaced.
•
Check the length (B), that it is according to the
ordered machine type.
