at the engine. Close the engine

) and open up the engine
cover.
Checking the engine oil level
Never allow the oil level to be too low other-
wise the engine can be damaged. Never fill in
too much oil. Otherwise, there is the risk that
the oil enters and destroys the air filter.
For this, observe the attached operating in-
structions of the engine.
Checking the spark plug
Danger!
The ignition system generates an
electromagnetic field.
Wearers of pacemakers must not
work on live parts.
Soiled spark plugs reduce the engine output.
Clean the electrode of the spark plug with a
brass wire brush. Check the electrode gap
(see operating instructions of the engine manu-
facturer). Make sure that the insulator around
the electrode is not damaged. Never use a
damaged spark plug.
Tighten the spark plug using the correct torque
(see operating instructions of the engine manu-
facturer).
Always check both spark plugs.
Maintaining the air filter
Danger!
Cleaning agents pose a fire and
explosion hazard.
Never clean the air filter with flam-
mable solvents.
Make sure that the air filter is always clean. A
dirty air filter reduces the engine power and
leads to increased engine wear and fuel con-
sumption. Independent of the operating hours,
change the filter insert at least once a year. Do
not operate the engine without air filter.
For this, observe the attached operating in-
structions of the engine.
