SCARIFICATION
Each year and on every lawn, moss and weeds take
hold, which cause the ground to become matted.
By scarifying, the hard surface is cut, allowing the
grass to breathe and take up nutritional substances,
oxygen and water.
Before scarifying, mow the lawn to a height of about
40 mm (an inch).
Only use the aerator when the lawn is dry.
March, April, and September are the best months
for scarifying.
Do this work at least once a year.
To get a nice green effect, we recommend using
a fertiliser immediately after having used the sca-
rification.
Empty the grass box in good time.
Only with the engine switched off and the cutting
gear at a standstill.
1. Lift the grass box.
2. Lift the discarge flap.
3. Remove the grass box by pulling it backwards.
If the grass box is over-filled, the discharge channel
in the housing of the aerator becomes blocked and
grass is left lying on the lawn.
Put the grass box back into place and start the
engine.
STARTING THE ENGINE
Once the machine has been set up properly, start the
engine as follows:
Engines with primer system:
Press the fuel-enrichment pump located on the
carburettor 3 or 4 times position the accelerator
lever (13) on MAX.
For further information and explanations, read care-
fully the user instruction manual of the engine.

pull it out again quickly a full arm's length for the start.
Keep the starter handle in your hand and allow the
rope to return slowly. Set the gas lever to match the
work you are doing.
After the start

position between ("START, MAX") and
