provides the best vibration damping and the
best breaking force.
◆
Avoid working in extremely hard material such
as granite and reinforcing iron, since such
materials can cause strong vibrations.
◆
Never block or cover the cooling air inlet (A)
during operation.
◆
Avoid idling; operation without a working tool
and operation with the machine lifted.
◆
Release the throttle lever when the machine is
lifted.
Breaking using special tools
For special applications such as asphalt cutting or
digging the machine can be operated sideways as
to line the working tool up in a specific direction.
Never block or cover the cooling air inlet (A).
◆
As a first measure, hold the machine so that the
air inlet faces away from you.
◆
As a second measure, under the condition that
the air inlet is never blocked or covered, hold
the machine so that the inlet faces towards you.
◆
It is also possible to rotate the working tool in
the tool chuck instead of rotating the actual
machine.
NOTICE To choose the correct working tool,
check the tool shank dimension specified on the
machine and see the spare parts list.
Breaking at high altitude
To get the best result when breaking at high
altitude, do the following:
◆
Check that the air filter is in good condition.
◆
If necessary, lean the fuel mix by turning the
main nozzle (A) clockwise.
◆
When finished with operating at high altitude,
turn back the main nozzle (A) to the default
position.
Tie tamping
Cobra TTe is designed for tie tamping.
Tie tamping is used for local maintenance of
railway tracks in an area up to 30 square meters.
Tie tamping stabilizes the ballast under the
sleepers.
To get the best result when tie tamping, do the
following:
◆
Two operators must operate on each side of the
sleeper. Operating on opposite sides will
compress the ballast down and up, and fill all
gaps and create stability.
◆
Lean the machine when operating. Do not
operate in a straight angle, it will compress the
ballast too deeply and reduce the stability.
◆
Operate for 2-3 seconds at one point before
moving to another operating point. Operating
