5.4 Electromagnetic compatibility (EMC)

The different electrical devices on board the vehicle 
cause electrical interference in the vehicle's electrical 
circuit. At MITSUBISHI FUSO, electronic components 
installed at the factory are checked for their 
electromagnetic compatibility in the vehicle.

When retrofitting electric or electronic systems, they 
must be tested for electromagnetic compatibility and 
this must be documented.

The equipment must have been granted type approval 
in accordance with FCC regulations.

The following standards provide information on this:

5.5 Welding work

All laws governing explosive substances must be 
complied with.

The following safety measures must be observed to 
prevent damage to components caused by 
overvoltage during welding work:

• Disconnect the positive and negative terminals 

from the battery and cover them.

• Connect the welding-unit ground terminal directly 

to the part to be welded.

• Do not touch electronic component housings 

(e.g. control modules) and electric lines with the 
welding electrode or the ground contact clamp of 
the welding unit.

• Before welding, cover springs to protect them from 

welding spatter. Do not touch springs with welding 
electrodes or welding tongs.

• Cover the fuel tank and fuel system (lines, etc.) 

before carrying out welding work.

• Avoid welding work on inaccessible cavities in the 

cab.

• Welds must be ground down and reinforced with 

angular profiles to prevent notching from welding 
penetration.

• Avoid welds in bends.
• The distance from a weld to the outer edge should 

always be at least 15 mm {0.59 in.}.

• Avoid defects such as deposited metal cracking, 

toe crack, blow holes, slag inclusion, under cut, 
poor penetration, etc.

!

Do not connect the arc welder ground clamp to 
assemblies such as the engine, gearbox or axles.

Welding work is not permitted on assemblies such 
as the engine, gearbox, axles, etc.

The following safety measures must be observed to 
prevent damage to welding parts;

• Do not weld any item to the frame to hold it 

temporarily.

• Clean parts thoroughly with a wire brush and dry 

them off before welding.

• Make sure the paint is completely removed, before 

welding a painted part.

• Use a low hydrogen type welding electrode.  The 

welding electrode absorbs moisture when it is 
used, so it is necessary to dry it thoroughly before 
use.

• When welding, maintain the optimum welding 

speed and conditions for the preservation of the 
welding electrode.

• Maintain the welding current at the optimum value 

for safety.

• Make several short welding beads rather than one 

long bead.

• Make symmetrical beads to limit shrinkage.
• Avoid more than 3 welds at any one point.
• Avoid welding in strain hardened zones.
• When connecting the ground cable of the arc 

welder, make sure to disconnect the negative 
terminal from the battery.  The ground of the 
welder should be connected to the side rail near 
the welded part.  Never connect around the engine, 
transmission, propeller shaft, front and rear axles, 
etc.

• When performing welding work on the chassis, 

take proper measure to prevent the tubes, 
harnesses, rubber parts, springs, etc. from heat or 
spatter. 

• Do not cool parts off with water after welding.

Risk of accident and injury

Before performing electric of arc welding as part of 
vehicle repair operation, disconnect the negative (-) 
cable from the battery.  The ground cable of the 
welding machine should be connected to a point as 
close to the welding area as possible.

5.6 Corrosion protection measures

General

In order to preserve the durability and quality standard 
of the vehicle, measures must be taken to protect it 
against corrosion when the vehicle is modified and 
after installing bodies and fittings.

Information on the design, execution of work and the 
requirements of the materials and components to be 
used with regard to corrosion protection is listed 
below.

To achieve good corrosion protection, the areas of 
design (1), production (2) and materials (3) must be 
perfectly matched.
