In order to prevent damage on the electronic modules, it is
necessary to perform the welding correctly. Whenever possible,
remove the component to be welded from the machine or
engine, and only after that carry out the operation/maintenance.
If it is necessary to perform the welding next to one of the engine
or machine electronic modules, remove it for a while, to prevent
possible damage due the heat or electric discharge.
To perform welding on machine or engine components, proceed
as follows:
1. Turn off the engine. Put the engine key starter switch in the
position "O".
2. Put the main switch in the position "OFF".
NEVER use electronic components (ECM or
ECM sensors) or electronic components linkage
points to the ground to turn on the welding
machine to the ground.
3. Remove the connectors from the machine electronic
modules (engine and transmission ECM, Multifunction
display etc) or remove the grounded cables from the
machine (3 on chassis and 2 on the cab). Refer to the
chapter "Electric System" in order to find the location of
these points.
4. Attach the ground connecting cable of the welding machine
to the structural component to be welded. Put the fastening
element as near as possible to the welding. Make sure that
the ground connecting cable reaches the structural
component without passing through any bearing. Follow the
procedure above to reduce the damage occurrence on the
components below:

Transmission bearings;

Hydraulic components;

Electric components;

Other components.
5. Protect the cables so there is no dirt on them due residues
remaining from the welding process. Protect the cables so
there is no dirt on them due residues remaining from the
welding process.
6. Adopt standardized techniques to perform welding on the
machine.
Any damaged inflicted on the electronic
components of the machine which result from the
failure in complying with the procedures above, will
invalidate the product warranty.
