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

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.

10
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.
