Design and function
Cobra Combi is a combined drilling and
hammering machine. It is equipped to be used for
breaking asphalt and concrete and for drilling in
concrete and granite. Equipped with the right
accessories, the machine can also be used for
driving posts, fences, and ground sampling. No
other use is permitted. For professional use only.
To choose the correct working tool, check the tool
shank dimension on the machine, and see the
spare parts list.
Choosing the correct breaker
for a task
It is important to choose the correct size of breaker
for the work to be performed.
A breaker that is too small means that the work will
take longer.
A breaker that is too large means that there must
be frequent repositioning, which is unnecessarily
tiring for the operator.
A simple rule for choosing the correct size of
breaker is that a normal sized piece of broken
material should be removed from the workpiece
within 10–20 seconds of operation.
•
If it takes less than 10 seconds, a smaller
breaker should be chosen.
•
If it takes longer than 20 seconds, a larger
breaker should be chosen.
