COBRA MK1, TT, TT-AWD
♦ Never break off too large pieces. Adjust the
breaking distance (A) so that the inserted tool does
not fasten.

Breaking

Never use the machine as a lever, the material
♦
should be broken by impact energy.
♦ If the tool fastens, never try to lift it by pulling on
the top of the fuel tank.
♦ Check that the handle bar can move freely (up
and down) without binding.
Let the machine do the work. Never press too
♦
hard. The vibration absorbing handle should never
be forced all the way to the bottom.
♦ The feed force should be adjusted so that the
handle is pressed "half way down". This position
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.
Avoid idling; operation without a inserted tool and
♦
operation with the machine lifted.
♦ Release the throttle lever when the machine is
lifted.

so that there is no risk for unintentional start.

Maintenance

Regular maintenance is a basic requirement for the
continued safe and efficient use of the machine.

♦ For major service to the machine, contact your
nearest authorised workshop.

Every day

Before undertaking any maintenance or changing
the inserted tool, turn the machine off.
♦ Perform a general inspection and check that there
are no leaks and no damage.
♦ Check that the tool holder is not worn and that it
functions as it should. Never use the equipment
if you suspect that it is damaged.
Check that the O-ring on the oil plug is undamaged
♦
and seals properly.
♦ Check that the oil plug is tight regularly.
♦ Check for wear in the tool bush.
♦ Check the insertion tool, make sure that it is sharp
and not worn out.
♦ Change damaged parts immediately.
♦ Replace worn components in good time.
In order to ensure that the machine remains within
the stated vibration level values, the following checks
must be performed:

Wear check

If a inserted tool with a worn shank is used, machine
vibration will increase. Avoid such vibration by
checking for shank wear before mounting the
insertion tool on the machine.
