7.1 Cleaning
The scari
fi
er should be cleaned thoroughly eve-
ry time after it has been used. This particularly
applies to its underside and the blades. To do so
tip the scari
fi
er slightly on to its side and remove
the dirt.
Important. Before you tip the equipment, the pet-
rol tank must be emptied to prevent petrol leaking
out. Ideally you should use a conventional petrol
extraction pump for this purpose.
7.2 Servicing
Checking the oil level
Set the equipment down on a
fl
at, level surface.
Unscrew the oil dipstick by turning it anti-clockwi-
se. The oil level must be as shown in Figure 10.
Important:
Never run the engine with no or too
little oil. This can cause serious damage to the
engine.
Changing the oil
•
Change the engine oil every year before the
start of the season (in addition to the informa-
tion in the petrol service manual) when the
engine is warm.
•
Use only recommended engine oil.
•
Place a suitable oil drip tray beneath the oil
drain screw.
•
Remove the oil filler screw (Fig. 9 / Item A).
•
Undo the oil drain screw (Fig. 9 / Item B) and
drain the oil into a suitable container.
•
Close the drain screw again when all the
used oil has been drained.
•
Pour engine oil into the equipment as shown
in Figure 10.
•
Dispose of the used oil in accordance with
applicable regulations.
Care and adjustment of the cables
Oil the cables at regular intervals and check that
they move easily.
Servicing the air
fi
lter
Soiled air
fi
lters reduce the engine output by sup-
ply too little air to the carburetor.
Regular checks are therefore essential. The air
fi
lter should be checked after every 50 hours of
use and cleaned if necessary. If the air contains a
lot of dust, the air
fi
lter should be checked more
frequently.
•
Remove the air filter as shown in Fig. 11-13.
•
Clean the air filter only with compressed air or
by tapping it.
•
Assemble in reverse order
Important:
Never clean the air
fi
lter with petrol or
in
fl
ammable solvents.
Servicing/Replacing the spark plug
Check the spark plug for dirt and grime after 10
hours of operation and if necessary clean it with
a copper wire brush. Thereafter service the spark
plug after every 50 hours of operation.
•
Pull off the spark plug boot (Fig. 14) with a
twist.
•
Remove the spark plug using a spark plug
wrench (Fig. 15).
•
Assemble in reverse order.
7.3 Preparing the equipment for storage
Caution: Do not empty the petrol tank in enclosed
areas, near
fi
re or when smoking. Petrol fumes
can cause explosions and
fi
re.
1. Empty the petrol tank with a petrol suction
pump.
2. Start the engine and let it run until any remai-
ning petrol has been used up.
3. Change the oil at the end of every season.
To do so, remove the used engine oil from a
warm engine and re
fi
ll with fresh oil.
4. Remove the spark plug from the cylinder
head. Fill the cylinder with approx. 20 ml of oil
from an oil can. Slowly pull back the starter
handle, which will bathe the cylinder wall with
oil. Screw the spark plug back in.
5. Clean the cooling
fi
ns of the cylinder and the
housing.
6. Be sure to clean the entire machine to protect
the paint.
7. Store the machine in a well-ventilated place.
7.4 Preparing the device for transport
1. Drain the petrol tank using a petrol extraction
pump.
2. Always let the engine run until it has used up
the remainder of petrol in the tank.
3. Empty the engine oil from the warm engine.
4. Remove the spark plug boot from the spark
plug.
5. Clean the cooling
fi
ns of the cylinder and the
housing.
6. Remove the push bars if necessary. Ensure
that the cables are not kinked.
