Safety instructions and warnings

SAFETY INSTRUCTIONS AND WARNINGS

1-3

Always use the appropriate lifting gear
(gearbox jack) or approved hoists for the
removal and installation of heavy
components. Attach the component
securely to the lifting or hoisting gear.

Be careful when working on systems which
may be under pressure, such as a trailing
axle lifting device, cab tilting mechanism,
brake system, steering gear, fuel system,
etc.

After a fire, hazardous residues may remain
from the plastics used in some oil seals and
sealing rings. Wear protective,
acid-resistant clothing and PVC gloves
when removing such fire residues. Immerse
such fire residues in, or sprinkle them
amply with, a calcium hydroxide solution
(slaked lime and water). Thoroughly clean
the protective clothing after use. Treat the
gloves as chemical waste.

1.2 BATTERIES

Always charge batteries in a
properly ventilated area and avoid
sparking and naked flames. Always
switch the battery charger off
before removing the leads.
Fast-charging should only be
resorted to in an emergency.
Disconnect the battery leads when
fast-charging is being used.

Wear protective clothing, gloves
and a visor when carrying out work
that may bring you into contact
with battery acid.

Battery acid is an aggressive fluid.
In the event of contact with the
skin: rinse the skin with plenty of
water for a sustained period. If
redness or pain persists, consult a
doctor. Remove any clothing
affected and rinse with water.
In the event of contact with the
eyes: Rinse with plenty of water for
at least 15 minutes and see a
doctor.
If any is swallowed: do NOT induce
vomiting. Rinse the mouth, drink
two glasses of water and see a
doctor.
In the event of inhalation: get some
fresh air, rest and consult a doctor.

To prevent damage to electronic components,
never disconnect the battery terminals when the
engine is running.

Always disconnect the earth connection of the
battery before working on the vehicle. Never
place tools on a battery. If you do, this could
short-circuit the battery or even cause the
battery to explode.

Always charge batteries in a properly ventilated
area and avoid sparking and naked flames.
When charging batteries, an explosive gas
mixture may be released.

1.3 WELDING

No welding of the chassis is
allowed without special, written
permission by DAF. Exceptions to
the above are the welding
operations described in the manual
“Superstructure directives”.
Non-compliance with welding
regulations may cause serious
damage to the chassis.

Failure to observe the following
instructions may damage the
electronic components.

General
-

Attach the earth clamp of the welding set as
close as possible to the area on the vehicle
where the welding is to be done and ensure
that it is well in contact with the part being
welded.

Never attach the earth clamp to vehicle
components such as the engine, axles,
springs, etc. Arcing on these components is
also not permitted. Non-compliance with the
above instructions may result in serious
damage to bearings, springs, etc.

The accessory or ignition position of the
ignition lock must not be switched on.
Remove the ignition key from the ignition
lock.

Protect plastic piping, rubber components,
plastic components, piston rods of hydraulic
cylinders and springs (in particular parabolic
springs) from welding splashes and
temperatures above 70

_C.

Welding on the chassis
-

When welding on the chassis, disconnect
the connectors of all electronic equipment
(including sensors and actuators), if they
are within a 1-metre radius from the point
being welded or within a 1-metre radius
from the earthing point.

Disconnect the battery terminals if these
are within a within a 1-metre radius from the
point being welded or the earth clamp.

If the battery terminals have to be
disconnected, all electronic units mounted
on the chassis must be disconnected as
well. Also disconnect the cab feed-through
connectors and disconnect the power
supply and earth cables that are connected
to the cab.

Welding on the cab
-

When welding on the cab, disconnect the
battery terminals.

Also disconnect the cab feed-through
connectors and disconnect the power
supply and earth cables that are connected
to the cab.

Disconnect the connectors of all electronic
equipment (including sensors and
actuators), if they are within a 0.5-metre
radius from the point being welded or within
a 0.5-metre radius from the earth terminal.

Welding on the superstructure
-

Follow the instructions for “Welding on the
chassis”, together with any specific welding
instructions for welding on the
superstructure.

Note:
During grinding, protect plastic piping, rubber
components, plastic components, piston rods of
hydraulic cylinders and springs (in particular
parabolic springs) in order to prevent damage
caused by grinding sparks.
