Safety regulations
Reattach all guards and safety installations after
all work has been completed.
Environment
It is strictly prohibited to drain off hydraulic oil
into the soil, the sewer system or into natural wa-
ters. Entrust special companies with the waste
disposal of old oil. If in doubt you should consult
your local authorities.
Fuels
Danger
!
Repair work on fuel systems must only be per-
formed by appropriately trained personnel.
The following notes refer to general safety precau-
tions for danger free handling of fuel. These notes are
only general instructions; in case of uncertainties you
should consult the person responsible for fire protec-
tion.
Fuel vapours not only are easily inflammable, but also
highly explosive inside closed rooms and toxic; dilu-
tion with air creates an easily inflammable mixture.
The vapours are heavier than air and therefore sink
down to the ground. Inside a workshop they may eas-
ily become distributed by draft. Even the smallest por-
tion of spilled fuel is therefore potentially dangerous.
Fire extinguishers charged with FOAM, SCHAUM,
●
CO2 GAS or POWDER must be available wherever
fuel is stored, filled in, drained off, or where work on
fuel systems is performed.
The vehicle battery must always be disconnected,
●
BEFORE work in the fuel system is started. While
working on the fuel system you should not discon-
nect the battery, because this could generate
sparks, which would ignite explosive fuel vapours.
Wherever fuel is stored, filled, drained off or where
●
work on fuel systems is carried out, all potential ig-
nition sources must be extinguished or removed.
Search lights must be fire proof and well protected
against possible contact with running out fuel.
Hot fuels
Before draining fuel off the tank for repair work, you
must strictly apply the following measures:
Allow the fuel to cool down, to prevent any contact
●
with a hot fluid.
Vent the system, by removing the filler cap in a well
●
ventilated area. Screw the filler cap back on, until
the tank is finally emptied.
Synthetic rubber
Many O-rings, hoses and similar parts, which are ap-
parently made of natural rubber, are actually made of
008 911 63
plastic material, a so-called fluoroelastomer. Under
normal operating conditions this material is safe and
does not impose any danger to health.
However, if this material becomes damaged by fire or
extreme heat, it may decompose and form highly
caustic hydrofluoric acid, which can cause severe
burns in contact with skin.
If the material is in such a state it must only be
●
touched with special protective gloves. These
gloves must be disposed of directly after use.
If the material has contacted the skin despite these
●
measures, take off the soiled clothes and seek
medical advice immediately. In the meantime wash
the affected parts of the skin for 15 to 60 minutes
with cold water or lime water.
Poisonous substances
Some of the fluids and substances used are toxic and
must under no circumstances be consumed.
Skin contact, especially with open wounds, should be
strictly avoided.
These fluids and substances are, amongst others,
anti-freeze agents, hydraulic oils, washing additives,
lubricants and various bonding agents.
Engine
Danger
!
Do not work on the fuel system while the engine is
running - danger to life!
After the engine has stopped wait until the pres-
sure has dropped (on Commonm Rail engines ap-
prox. 5 minutes, other engines 1 minute), because
the system is under high pressure - danger to life!
Keep out of the danger zone during the initial test
rung. Danger caused by high pressure in case of
leaks - danger to life!
When performing work on the fuel system make
sure that the motor cannot be started unitention-
ally - danger to life!
Maintenance and cleaning work on the engine must
●
onyl be performed with the engine stopped and
cooled down. Make sure that the electric system
has been switched off (ignition key pulled out).
Observe the accident prevention regulations for
●
electric systems (e.g. -VDE-0100/-0101/-0104/-
0105 Electric precautions against dangerous con-
tact voltages).
Cover all electric components properly before wet
●
cleaning.
