Safety and operating instructions

Overview

To reduce the risk of serious injury or death to
yourself or others, read the Safety instructions
section found on the previous pages of this
manual before operating the machine.

Design and function

Cobra Pro is designed for medium to heavy
demolition of material such as concrete and asphalt.
Cobra TT and TT-AWD are designed for tie tamping
and can also be used for medium demolition of
material such as asphalt.
The petrol breaker is designed for vertical use only.
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.
