charge chute (8) is locked in place.
To remove the side discharge chute:
–    P ush the safety lever (3) slightly and lift the side dischar-
ge guard (4).
– Release the side discharge chute (8).
To remove the chute flap:
– Lift the rear discharge guard (1).
–    P ush in the middle to release the tooth (7).
3.2 Engine ignition
During  ignition,  follow  the  instructions  in  the  engine  ma-
nual.
3.2a
• Manual ignition models ("I - "II" - "III")
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).
3.2b
• Electric push-button ignition models ("IV - "V")
–  Insert  the  supplied  battery  in  the  relative  engine  com-
partment (4); (follow the instructions provided in the en-
gine manual).
–  Insert the key as far as possible (if fitted) (5).
–  Pull  the  engine  cutting  means  brake  lever  towards  the 
handle (1).
NOTE Keep pulling the engine / cutting means brake or
the engine will stop.
– Press and hold the starter button until the engine
switches on (6).
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;
– lift the rear discharge guard, grasp the handle and re-
move the grass catcher keeping it in an erect position.
• For mulching or rear grass discharge: 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 according to the lawn condi-
tions 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.
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 perfor-
mance 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)    P aint  on  internal  chassis  parts  may  start  to  flake  over 
time due to the abrasive action of cut grass; if this hap-
pens, 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,  fol-
lowing  the  relevant  instructions,  making  sure  that  the 
machine  is  perfectly  stable  before  performing  any  in-
terventions.  On  side  discharge  models,  remove  the  di-
scharge chute (if installed – see 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)  ì  U se the specific attachment for the water hose to clean 
the internal parts of the chassis (if provided). To per-
form the cleaning, adjust the cutting height to the low-
est setting, then start the engine and engage the cutting
means, standing behind the lawnmower handle. 
7)    T o  ensure  that  the  machine  will  function  properly  over 
time,  it  is  highly  recommended  to  change  the  engine 
oil  regularly,  following  the  timing  indicated  in  the  en-
gine's Instruction Manual. The oil can be discharged
at a specialised servicing centre, or by using a syringe 
to  suction  the  oil  out  through  the  filler  spout,  bear-
