WELDING THE CRANE
•
•
•
•
If repair welding of structures is required, it is essential to contact the production plant, which
will provide the necessary repair instructions and other considerations. Repair welding has to
be carried out professionally, as an inadequately repaired structure may suddenly break and
cause an accident.
•
Turn off the drive unit and turn its ignition key to position 0.
•
Open the main switch.
•
Protect sensitive components from welding spatters.
•
Attach the welding machine's grounding cable directly to the component to be welded. Attach
the cable as close as possible to the welding point, so that the welding current does not pass
through bearings, hydraulic components or electronic components.

INSTALLING
STRUCTURE
Any changes made to the crane without Kesla's approval and a reap-
praisal of risks can result in death, serious injury or material damage.
All changes and repairs that are not listed in the maintenance manual
and that may affect the machine's operation, safety and usability, are
subject to Kesla's approval before they are carried out. The approval
requires a careful risk analysis during the planning phase that would
take into account the remaining risks and any new risks possibly
caused by the changes.
•
If changes and corrections are made without Kesla's permission that hamper the machine's
operation, safety and usability, the manufacturer is not liable for any events causing death, inju-
ry or material damage, which is the result of such changes or repairs.
•
Changes without Kesla's permission may invalidate the warranty.
•
Contact the manufacturer before making any changes in the crane structure. Modifying the
structure may result in an overload situation and risk of accidents.
Determine the material to be welded and the appropriate welding
process and consumables before welding. If necessary, contact
Kesla.
Follow the welding instructions and use appropriate welding meth-
ods.
Always wear appropriate safety equipment.
