7.4.2.2 Air filter
The air filter protects the carburettor against dust and dirt by filtering the sucked-in air and
keeping back coarse particles. It must be checked and cleaned at regular intervals so that it
can perform its task properly.
Removing and cleaning the air filter
¨
Remove the housing cover on the right, see
page 109.
¨
Undo the screw in the centre of the air filter
housing and remove the housing cover.
¨
Carefully pull the air filter out of the air filter
housing.
Inspect the air filter for damage. Do not
¨
continue using a damaged filter, instead
replace it immediately.
Clean the air filter thoroughly:
¨
– Use a non-flammable solvent to thoroughly
wash out the air filter.
– Then dry the air filter and allow surplus
solvent to evaporate.
¨
Prepare the air filter with engine oil:
– First saturate the air filter with clean engine oil.
– Press out surplus engine oil and allow the air filter to drain off.
¨
Put the air filter back into the air filter housing so that it fits perfectly. The air filter material
must not be deformed or squashed by rotation.
Screw the air filter cover tightly into place and secure the genset's housing cover.
¨
7.4.2.3 Spark plug
The spark plug ignites the petrol/air mixture in the combustion chamber to start the drive
motor. This only works continuously without faults if the spark plug is cleaned at regular
intervals and is checked to make sure that the electrode gap is correct. A faulty spark plug
must be replaced immediately (spark plug type: BPR6HS NGK).

ATTENTION!
¨
Never start the genset with no air filter inserted. The ingress of dust
particles into the engine can result in increased wear caused by an abrasive
effect.
¨
Shorten the maintenance interval specified for the air filter as required if
the genset is used more frequently in a dusty environment.
