section found on the previous pages of this

manual before operating the machine.

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.

To choose the correct insertion 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 operation.

● If it takes less than 10 seconds a smaller breaker

should be selected.

● If it takes more than 20 seconds a larger breaker

should be selected.
