nance manual.

CAUTION:- 0.6l Oil must be added to the

engine before use

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-

rication.

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 ap.

3. Remove the grass box by pulling it backwards.

If the grass box is over-lled, 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.

Manual start of the engine

The exhaust fumes contain carbon monoxide,

a non-odorous and lethal gas!

For this reason, never start the engine in

enclosed or badly ventilated rooms.

Do not start the motor when the blade unit

is in the operating position.

Pull the lever (16) up to lift the blade unit.

Push the gas lever (13) to the position ”START”.

Press the injection pump 2 to 3 times. There should

be a 2 second gap in between each pressing.

Attention!

At temperatures below +10°C, press the rubber bel-

lows 5 times. Never use the bellows when the engine

has reached operating temperature.

Press push button (15) and pull STOP switch lever

(14) towards the handle and hold it in this position.

If the engine brake bracket is not pulled, the starter

cord cannot be pulled out as a result of the engine

brake.

Pull out the starter cord until a compression resistan-

ce can be felt. Allow the cord to return slowly and then

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

As soon as the engine is running, put the gas lever to

position between (“START, MAX”) and

(“STOP, MIN”) at a speed which you think matches

the work you are doing.

Stopping the engine

Please remember that the blade continues to

run for a few seconds after switching off.

Therefore, do not put your hands under the

scarier immediately after switching it off.

Release the lever of switch (14) to turn off the

engine.

Put the gas lever to or MIN. (Stop).
