SAFETY PRECAUTIONS FOR HANDLING
MATERIALS
Fuel and lubricating oil
WARNING
All fuels and lubricants as well as many chemicals
are flammable. Always follow the instructions on the
relevant packaging,
The work must be carried out on a cold engine. Fuel
leaks and spillage on hot surfaces can cause fire.
Store used rags and other flammable materials safely
so as to avoid spontaneous combustion.
Batteries
WARNING
The batteries contain and form oxyhydrogen gas,
particularly during charging. Oxyhydrogen gas is
flammable and highly explosive.
There must be no smoking, naked flames or sparks
near the batteries or the battery compartment.
Incorrect connection of a battery cable or jump lead
can cause a spark, which can cause the battery to
explode.
Environment
Always hand in used batteries to an authorised waste
disposal contractor.
Chemicals
WARNING
Most chemicals such as glycol, anti-corrosive
agents, preservative oils and degreasing agents, are
hazardous to health.
Some chemicals, such as preservative oil, are also
flammable.
Always follow the safety precautions on the relevant
packaging,
Store chemicals and other materials which are
hazardous to health in approved containers, marking
them clearly and storing them where they are
inaccessible to unauthorised persons.
Environment
Always hand in leftover and used chemicals to an
authorised waste disposal contractor.
SAFETY PRECAUTIONS FOR MAINTENANCE AND
REPAIR
Switch off the engine
Always switch off the engine before carrying out
maintenance and repair work, unless otherwise
indicated.
Make it impossible to start the engine: Remove any
starter key, or cut the power using the main power switch
or battery master switch and lock them.
Fix a warning plate somewhere appropriate, showing that
work is being carried out on the engine.
WARNING
Working with a running engine always poses a safety
risk. Parts of the body, clothes or dropped tools can
get caught in rotating parts and cause injury.
Hot surfaces and fluids
WARNING
There is always a risk of sustaining burns when an
engine is hot. Particularly hot parts are engine
manifolds, turbochargers, oil sumps, hot coolant and
oil in pipes and hoses.
Lifting the engine out
Always use the engine lifting eyes. Always check that
lifting devices are in good condition and are designed to
lift the weight.
Optional equipment on the engine can change the centre
of gravity, This means that it may be necessary to use
additional lifting devices to balance the engine correctly
and lift it safely.
WARNING
Never work underneath a suspended engine!
