4.1.3 Fuelling
WARNING!
Always shut off the engine
and let it cool for at least two
minutes before fuelling.
Avoid spilling fuel.
If you do spill fuel when fuelling,
do not start the engine before
the spilled fuel has evaporated.
If the washer is on a trailer, any
fuel spills must be wiped up
before the machine is started.
Never expose the machine
to an open fl ame. Smoking is
prohibited during fuelling. Also
read the operating manual for
the fuel engine.
Note:
Never operate the
ma chine in a closed room; the
exhaust fumes are dan ger ous.
Follow the safety instructions
in chapter 1!
