Safety Precautions
Some of the most important safety precautions follow.
However, we cannot warn you of every conceivable
hazard that can arise in performing maintenance. Only
you can decide whether or not you should perform a
given task.
WARNING
Failure to properly follow maintenance instructions
and precautions can cause serious injury or death.
Always follow the procedures and precautions in the
operations manual. Where third party equipment is
incorporated into the generator always refer to their
guides for familiarisation
•
Make sure the engine is off before you begin any
maintenance or repairs. This will eliminate several
potential hazards:
•
Read the instructions before you begin, and make
sure you have the tools and skills required.
•
To reduce the possibility of
fi
re or explosion, be
careful when working around petrol. Use only a
non
fl
ammable solvent, not petrol, to clean parts.
Keep cigarettes, sparks, and
fl
ames away from all
fuel-related parts.

nance items for servicing your generator.
