1.7 SAFETY REGULATIONS FOR WELDING
WORK
Failure to observe the welding regulations may cause seri-
ous damage to the chassis.
General information
– Before starting any welding work on the bodywork or chas-
sis frame, both the negative cable and the positive cable
must first be disconnected from the batteries.
– Disconnect the connectors for the central electrical box,
the generators, the electrical components, the electronic
units, the CMU, the ECU, the IOU, the ABS unit, the dash-
board and the ECM.
– Attach the welding set’s earth clamp as close as possible
to the area on the vehicle where the welding work is to be
carried out and ensure that it makes good contact with the
area being welded.
– Never attach the earth clamp to vehicle components, such
as the engine, axles, springs, etc. Arcing on these compo-
nents is also not permitted. Failure to observe these
instructions may result in serious damage to bearings,
springs, etc.
– The accessory or contact position of the contact lock/con-
tact switch/main switch must not be turned on.
Remove the key from the contact lock.
– Cover inflammable materials during welding and grinding.
Welding splashes and grinding sparks can ignite materials
and cause the fast dispersion of fire.
– Protect plastic lines, rubber components, wiring har-
nesses, operating cables, plastic components, piston rods
of hydraulic cylinders, air bellows and springs (in particular,
parabolic springs) against welding splashes. These com-
ponents must not be exposed to temperatures greater than
70° C.
– After welding, apply a primer and paint to the welded areas
and repair any paint damage.
Also pay attention to any paint damage on the underside of
the welded area.
It is not permitted to carry out welding
work on the vehicle without special
written permission from VDL Bus &
Coach,
Failure to observe the instructions below
may damage the electronic components.
