the engine will stop.
– Press and hold the starter button until the engine
switches on (6).
3.2 Mowing the lawn
The  appearance  of  the  lawn  will  improve  if  you  alternate 
cutting in both directions at the same height.
A machine that is equipped with a MULCHING system cuts 
the grass, chops it then distributes it over the lawn. It is not 
necessary to collect the cut grass.
For best MULCHING results, proceed as follows:
1.    N ever cut the grass too short. Only cut the grass by 1/3 
of its height.
2.    K eep the body shell perfectly clean (underneath).
3.    A lways use well sharpened cutting means.
4.    A void  mowing  wet  grass.  It  accumulates  more  easily 
under  the  body  shell  and  the  mowing  performance  de-
creases considerably.
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.
3.3
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
      R emove the ignition key (3).
• Electric push-button ignition models
      P ress 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) 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,  fol-
lowing  the  relevant  instructions,  making  sure  that  the 
machine  is  perfectly  stable  before  performing  any  in-
terventions.
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)    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  engine's 
Instruction Manual.
The oil can be discharged at a specialised servic-
ing  centre,  or  by  using  a  syringe  to  suction  the  oil  out 
through  the  filler  spout,  bearing  in  mind  you  may  need 
to  repeat  the  operation  several  times  in  order  to  com-
pletely empty the tank.
Remember to top-up with oil before using the ma-
chine again.
4.1 Cutting means maintenance
It is best if all interventions on the cutting means are done 
at a specialised Centre that has the most appropriate tools 
and equipment.
Only cutting means bearing the code indicated in the table 
on page ii must be used on this machine.
Given  product  evolution,  the  above  mentioned  cutting 
means may be replaced in time with others having similar 
interchangeable and operating safety features. 
Reassemble  the  cutting  means  (2)  with  the  code  facing 
the ground, following the steps indicated in the illustration.   
Tighten the central screws (1) using a torque wrench set to 
the values specified for each type of cutting means.
4.2 Drive adjustment
On  power-driven  models,  remove  the  guard  (1)  once  or 
twice  a  year  by  unscrewing  the  screws  (2)  and  releasing 
the  fittings  (3)  (if provided).  Then  clean  carefully  using  a 
brush or compressed air, removing the grass and dirt from 
the  area  around  the  transmission  and  belt.  Always  reas-
semble the guard (1).
1.    P ush  the  lawnmower  back  and  forth  with  the  transmis-
sion disengaged.
2.    S et  the  clutch  control  to  position  «
lawnmower until the front wheels engage. 
3. In this position, the spring (11) should have an extension
of 6 mm as opposed to the position when unloaded, to 
guarantee sufficient transmission locking force. 
4.    I f the spring is not sufficiently extended, adjust the wire 
nipple (13) near the bar.
5.    S tart  by  loosening  the  locknut  (12)  and  then  adjust  the 
nipple (13).
6.    S et the clutch control to the « » position and check that 
the  transmission  is  disengaged  by  pushing  the  lawn-
mower back and forth.
