Tips for proper working
It is recommended that you overlap scarifying
paths a little. Try to scarify in straight lines for a
nice, clean look. Insodoing, the aeration swaths
should always overlap each other by a few centi-
meters in order to avoid bare strips.
As soon as grass clippings start to trail the scari-
fi
er, it is time to empty the grass basket.
Warning!
Before taking o
ff
the grass basket,
switch o
ff
the motor and wait until the roller has
come to a stop.
To remove the grass basket, lift up the ejector
fl
ap
with one hand, while unhooking the basket with
the other.
How frequently you should scarify your lawn is
determined primarily by the speed at which the
grass grows and the hardness of the soil.
Keep the underside of the equipment clean and
remove soil and grass build-up. Deposits make it
more di
ffi
cult to start the aerator and decrease the
quality of the scarifying.
Always scarify along inclines (not up and down).
Switch o
ff
the motor before doing any checks on
the roller.
Warning!
The roller rotates for a few seconds
after the motor is switched o
ff
. Never attempt
to stop the roller. In the event that the rotating
roller strikes an object, immediately switch o
ff
the equipment and wait for the roller to come to a
complete stop. Then inspect the condition of the
roller. Replace any parts that are damaged.
7. Cleaning, maintenance, storage,
transport and ordering of spare
parts
Warning!
Never work on or touch conducting parts on the
ignition unit with the engine running. Always pull
the spark plug boot from the spark plug before
starting any work of care or maintenance. Never
perform any work on the machine while it is run-
ning. Any work not described in these Operating
Instructions must be performed by an authorized
service workshop only.
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.
Notice!
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 the throttle lever in the P position. For a
description, see Section 7.3/Point 8.
•
Empty the petrol tank with a petrol suction
pump and run the engine until the remaining
fuel is fully consumed.
•
Place an oil drip tray alongside the equip-
ment.
•
Open the oil filler plug (Fig. 8a/Item A) and tilt
the equipment 90°.
•
The hot oil will flow through the open oil filler
opening into the oil drip tray.
•
After the old oil has drained out, set the
equipment upright again.
•
Fill up with engine oil as shown in Fig. 8a/b.
•
Dispose of the used oil in accordance with
applicable regulations.
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. 13a/13b.
•
Clean the air filter only with compressed air or
by tapping it.
