Safety precau-

operation
Preventive and
corrective main-
tenance
Safety inspection
Only operate the machine if all of its protective features are fully functional. If
any of the protective features are not fully functional, this endangers:
- the life and well-being of the operator or other persons
- the equipment and other tangible assets belonging to the owner/operator
- efficient working with the equipment.
Any safety devices that are not fully functional must be put right before you
switch on the machine.
Never evade safety features and never put safety features out of order.
Before switching on the machine, ensure that nobody can be endangered by
your doing so.
- At least once a week, check the machine for any damage that may be
visible from the outside, and check that the safety features all function
correctly.
- Always fasten the shielding-gas cylinder firmly, and remove it altogether
before hoisting the machine by crane.
- Owing to its special properties (in terms of electrical conductivity, frost-
proofing, materials-compatibility, combustibility etc.), only original coolant
of the manufacturer is suitable for use in our machines.
- Only use suitable original coolant of the manufacturer.
- Do not mix original coolant of the manufacturer with other coolants.
- If any damage occurs in cases where other coolants have been used,
the manufacturer shall not be liable for any such damage, and all
warranty claims shall be null and void.
- Under certain conditions, the coolant is flammable. Only transport the
coolant in closed original containers, and keep it away from sources of
ignition.
- Used coolant must be disposed of properly in accordance with the
relevant national and international regulations. A safety data sheet is
available from your service centre and on the manufacturer's homepage.
- Before starting welding - while the machine is still cool - check the
coolant level.
With parts sourced from other suppliers, there is no certainty that these
parts will have been designed and manufactured to cope with the stressing
and safety requirements that will be made of them. Use only original spares
and wearing parts (this also applies to standard parts).
Do not make any alterations, installations or modifications to the machine
without getting permission from the manufacturer first.
Replace immediately any components that are not in perfect condition.
When ordering spare parts, please state the exact designation and the
relevant part number, as given in the spare parts list. Please also quote the
serial number of your machine.
The manufacturer recommends that a safety inspection of the device is
performed at least once every 12 months.
The manufacturer recommends that the power source be calibrated during
the same 12-month period.
