–    P ush  the  safety  lever  (3)  slightly  and  lift  the  side  dis-
charge guard (2).
–    I nsert the side discharge chute (6) as shown in the figure.
–    L ower  the side discharge guard (2) so that the side dis-
charge chute (6) is locked in place.
• Only for models DM:
3.1e Preparation for grass cutting and collection in
the grass catcher:
– Lift the rear discharge guard (4) and fasten the grass
catcher (5) correctly as shown in the illustration.
3.1f Preparation for mowing and rear discharge of
grass:
–    L ift    the  rear  discharge  guard  (4)  and  remove  the  the 
grass catcher (5).
3.1g Preparation for mowing and mulching
–    L ift the rear stone-guard (4) and fit the chute cap (11) in 
the discharge opening, pushing it until the fastener tooth 
clicks into place (12).
To  remove  the  deflector  cap  (11),  use  the  lever  (13)  under 
the grip to release the tooth (12) and remove the deflector 
from the discharge opening.

3.2 Engine ignition

During ignition, follow the instructions in the engine manual
• Manual ignition models
Pull  the  cutting  means  brake  lever  (1)  against  the  handle 
and firmly tug the knob on the ignition cable (2). 
• Electric key ignition models
Pull  the  cutting  means  brake  lever  (1)  against  the  handle 
and turn the ignition key (3).
• Electric push-button ignition models
Insert the consent key (4) firmly in its seat, then pull the cut-
ting means brake lever (1) against the handle, press the ig-
nition button (5) and hold until the engine is running.

3.3 Mowing the lawn

The  appearance  of  the  lawn  will  improve  if  you  alternate 
cutting in both directions at the same height.
When  the  grass  catcher  is  too  full,  grass  collection  is  no 
longer efficient and the sound of the lawnmower changes.
To remove and empty the grass catcher, 
–    s top the engine and wait for the cutting means to stop;
–    l ift  the  rear  discharge  guard,  grasp  the  handle  and  re-
move the grass catcher keeping it in an erect position.
• For mulching: always  avoid  removing  a  large  quantity 
of grass. Never cut more than one third of the total grass 
height per single pass!  Regulate the forward speed ac-
cording  to  the  lawn  conditions  and  the  amount  of  grass 
removed.
• For side discharge (if applicable): it is best to mow in 
a pattern where cut grass is not discharged on the grass 
still to be cut.
• For a grass catcher with contents indicator device
(if applicable): while  working  with  the  cutting  means 
running,  the  indicator  remains  raised  for  as  long  as  the 
grass catcher is able to hold cut grass; when it lowers, it 
means that the grass catcher is full and must be emptied.
• Only for DML models:
IMPORTANT NOTE – If while working, you need to switch 
the  discharge  selection  switch  (*  2.5)  from  position  «B» 
(mulching)  to  another  with  the  lever  in  position  «A»  (rear 
discharge), turn off the machine and remove any grass from 
the  sliding  hatch  (1);  grass  on  the  hatch  may  prevent  the 
discharge selection lever from moving completely.
Lawn care recommendations
Each  type  of  grass  has  different  characteristics  and  may 
thus  require  different  ways  of  caring  for  the  lawn;  always 
read the instructions on seed boxes for mowing height for 
the growing conditions in the work area.
Keep in mind that most grass is made up of a stem and one 
or more leaves. If leaves are fully cut, the lawn is damaged 
and growth is more difficult.
The following indications generally apply:
–    c utting  too  low  tears  and  uproots  the  grass,  giving  it  a 
"spotted" appearance;
–    i n  the  summer,  cutting  must  be  higher  to  prevent  the 
ground from drying;
–    d o not cut wet grass; this could reduce cutting means ef-
ficiency due to sticky grass and tear the lawn.
–    f or particularly high grass, initially mow at the maximum 
height allowed by the machine then mow again after two 
or three days.
3.4

When work is finished

When work has been completed, release the brake lever (1) 
and disconnect the spark plug cap (2). 
• Electric key ignition models
Remove the ignition key (3).
• Electric push-button ignition models
Press the tab (5) and remove the consent key (4).
WAIT UNTIL THE CUTTING MEANS STOPS before pro-
ceeding any further.

4. ROUTINE MAINTENANCE

Store the lawnmower in a dry place.
IMPORTANT Routine and accurate maintenance is es-
sential in maintaining original machine safety and perform-
ance levels.
Adjustments or maintenance operations must only be per-
formed with the engine switched off and the spark plug ca-
ble disconnected.
1)    W ear  strong  protective  gloves  before  cleaning,  main-
taining or adjusting the machine.
2)    A ccurately  wash  the  machine  with  water  after  cutting; 
remove grass debris and mud accumulated in the chas-
sis  to  prevent  it  from  drying  and  causing  problems  the 
next time the lawnmower is used.
3) On models with painted chassis: paint on internal
chassis  parts  may  start  to  flake  over  time  due  to  the 
abrasive  action  of  cut  grass;  if  this  happens,  promptly 
touch-up  with  rust-proof  paint  to  prevent  rusting  that 
could corrode the metal.
4)    I f accessing the lower part is necessary, only tilt the ma-
chine on the side indicated in the engine manual, follow-
ing the relevant instructions. On side discharge models, 
remove the discharge chute (if installed –    s ee 3.1.d).
5) Do not drip petrol onto the plastic parts of the engine or
the machine to prevent damaging them and remove all 
traces of spilled petrol immediately. The warranty does 
not cover damage to plastic parts caused by petrol.
6) On models with AVS: If the handle vibrates unusually, 
check the anti-vibration sleeves and contact your Dealer
