Maintenance
Place the generator in such a way that a suitable catching pan can be placed
under the oil drain screw.
Ensure that the generator is mounted horizontally.
Wait after previous operation for at least five minutes before changing the oil
to allow the oil to flow into the oil sump and for the engine oil to cool off.
NOTICE!
Leaking engine oil contaminates the soil and groundwater.
► Use a suitable oil catching receptacle.
► Old oil is a special waste and may only be disposed of over suitably qualified
collection points.

Maintenance of the air filter
The air filter insert must be cleaned every 50 operating hours and also
changed if necessary. Operation with a dirty filter increases fuel consump-
tion, pollutant emissions and engine wear. A damaged or missing air filter
can destroy the engine.
Proceed as follows to service the air filter.
Requirements
The generator is switched off.
The engine is cooled down sufficiently.
A new air filter insert is ready to use.
