up or down-wards the height lever near the

wheels (picture F).

The lawn-mower allows 6 cutting height

positions from 20 mm up to 65 mm.

Note: the recommended cutting height for

most lawns corresponds to medium position.

The quality of cutting and grass colection may

be aected by a overly low cutting height.

4.2. How to start and stop

4.2.1. How to start the lawn-mower

1. Connect the extension cable to the comands

device;

2. Be sure that the extension cable doesn’t

stand under the lawn-mower;

3. Connetc the extension cable to the power

supply socket;

4. The comands device is equipped with a

“lock off” button, which helps to prevent

that the machine starts unexpectedly. Press

the button “lock off” and than press the

“on/off” lever on the device, keeping it

pressed for the entire period the machine

is intended to function. When the “on/off”

lever is pressed the “lock off” button must

be released (picture G)

Note: do not press/release the “on/o”

lever repeatedly, as this can cause serious

damages to the engine.

4.2.2. How to stop the lawn-mower

1. Release the “on/o” lever (Picture H).

4.3. How to know when the grass bag is full

As the grass bag becomes full the level

indicator cover becomes gradually closed

(picture I). When the cover is completely

closed, shut o the machine and empty the

grass bag contents.

4.4. How to apply the mulching adapter

1. For taking this procedure the lawn-mower

must be turned o and disconnected from

the power source. The user must wear

adequate gloves and clothing.

2. Remove the grass bag from the machine;

4. Place the mulching adapter as shown on

picture K. Be sure that the mulching adapter

is properly xed before replacing the

machine on its normal position.

4.5. How to mow

This lawn-mower can be used to mow in the

following dierent ways:

- With grass bag applied : the grass is eectively

colected and compressed inside the bag.

- With mulching adaptor : the grass is cut

and smashed in to very little pieces which

will turn into a good fertilizer for the lawn.

1. Start mowing on the area next to the

power supply socket, so that the extension

cable may extend over the lawn as you get

far from the socket.

2. Mow more often during the growth period,

as the grass must be cut maximum a 1/3

height at a time.

Do not overcharge the lawn-mower

Cutting a too high grass will lead to a lower

engine rotation which can be clearly heard.

As speed decreases, the engine may become

overloaded and the lawn-mower damaged. If

the grass is very high and dense the rst cut

must be made at a reasonable height, and, if

you want a shorter grass, cut it a second time

at a lower height. This is a good way to avoid

the engine overcharge.
