5.3 DIRECTIONS BEFORE STARTING WORK
Before starting to mow, it is necessary to carry out several checks and operations to
ensure you can work efficiently and in maximum safety.
5.3.1 Seat adjustment
To change the seat position, loosen the four fixing
bolts (1) and slide it along the slots.
Once you have found the right position, tighten
the four screws (1).
5.3.2 Tyre pressure
Having the right tyre pressure is the main condi-
tion for ensuring that the cutting deck is horizon-
tal and mows evenly.
Unscrew the valve caps and connect a com-
pressed air line with a gauge to the valves.
The pressures are:
FRONT 1.5 bar (13 x 5.00-6)
1.0 bar (15 x 5.00-6)
REAR 1.2 bar

5.3.3 Filling with oil and fuel
The engine manual indi-
cates what type of oil and fuel you can use.
With the engine off, check the oil level.
According to the instructions in the engine
manual, this must be between the MIN and
MAX marks on the dipstick.
Refuel using a funnel, but do not
completely fill the tank.
The tanks capacity is about 6 liters
(Type I) or 4.5 liters (Type II). 
Refuelling
should be carried out in an open or
well-ventilated area with the
engine off. Always remember that
petrol fumes are inflammable. DO
NOT USE A NAKED FLAME TO
LOOK INSIDE THE TANK AND DO
NOT SMOKE WHEN REFUELLING.
Do not drip petrol onto the plastic parts to avoid damaging them.
In the event of accidental spills or leaks, rinse immediately with water. The warranty
does not cover for damage to plastic parts of the bodywork or the engine caused by
petrol.
5.3.4 Fitting the protection at the exit (grass-catcher or stone-guard)
Never use the machine without having fitted the exit guards!!WARNING!

							20ENHOW TO USE THE MACHINE
Attach the grass-catcher (1) to the brackets (2) and
centre it up with the rear plate, so that the two ref-
erence marks (3) coincide.
Centering is ensured by using the right bracket as
lateral support.
Make sure that the lower pipe of the grass-catcher
opening is attached to the pawl (4).
If you decide to mow without the grass-catcher,
you can mount an optional stone-guard kit  (☛8.2).
This has to be attached to the rear plate as indicat-
ed in the instructions.
5.3.5 Checking machine safety and efficiency
1. Check that the safety devices function as described  (☛5.2).
2. Check that the brake is in perfect working order.
3. Do not start mowing if the blades vibrate or if you are unsure whether they are
sharp enough. Always remember that:
– A badly sharpened blade pulls at the grass and causes the lawn to turn yellow.
– A loose blade causes unwanted vibrations and can be dangerous.
Do not use the machine if you are unsure whether it is work-
ing safely or efficiently. If in doubt, contact your Dealer immediately to make
the necessary checks and repairs.

area! ALWAYS REMEMBER THAT EXHAUST GASES ARE TOXIC!
To start the engine:
– open the fuel stopcock (1)  ( if fitted);
– shift in the gear into neutral («N») (☛4.22 or 4.32);
– disengage the blades (☛4.7);
– apply the parking brake on sloping ground;
– when starting from cold, move the throttle to the
«CHOKE» position shown on the label;
– if the engine is already warm, position the lever
between «SLOW» and «FAST»;
– put in the ignition key and turn to «ON» to make electri-
cal contact, then turn to «START» to start the engine;
– release the key once the engine has started.
When the engine has started, move the throttle to «SLOW».
The choke must be closed as soon as the engine is running
smoothly. Using it when the engine is already warm can foul the spark plugs and
cause the engine to run erratically.
If there are engine starting problems, do not insist as you can risk
running the battery flat and flooding the engine. Turn the key to «OFF», wait for a few
seconds and then repeat the operation. If the malfunction persists, refer to the
engine manual and chapter «7» in this manual.
Always bear in mind that the safety devices prevent the engine
from starting if safety requirements have not been met (☛5.2).
In these cases, once the situation has been corrected, the key must first be turned
back to «OFF» before the engine can be restarted.
5.4.2 Starting and moving without mowing
This machine has not been approved for use on public roads.
It has to be used (as indicated by the highway code) in private areas closed to
traffic.
When moving the machine, the blades must be disengaged and the cutting deck
raised as high as possible (position «7»).

							22ENHOW TO USE THE MACHINE
Position the throttle between «SLOW» and
«FAST», and the gear lever in 1st gear (☛4.22).
Keep the pedal pressed down and release the parking brake. Slowly release the
pedal to shift from “brake” to “clutch”, thus operating the rear wheels (☛4.21).
The pedal has to be released gradually, as a sudden
engagement may cause the vehicle to tip over and the driver to lose control.
Gradually reach the desired speed using the throttle and gear lever. To change gear,
press the clutch halfway down (☛4.21).
When moving the machine from one area to
another, position the throttle between «SLOW» and «FAST».
Disengage the parking brake and release the brake pedal (☛4.31).
Press the drive pedal (☛4.32) in direction «F» and reach the required speed by
gradually increasing pressure on the pedal and working the throttle.
Drive must be engaged as described  (☛4.32) ) to prevent
sudden engagement from causing tipping up and loss of control of the vehicle,
particularly on slopes.
5.4.3 Braking
First reduce the machine’s speed by reducing the engine’s r.p.m., and then press the
brake pedal (☛4.21 or 4.31) to slow down the machine until it stops.
The machine already slows down considerably
by just releasing the drive pedal.

5.4.4 Reverse
Reverse must be engaged only when the machine has stopped
moving.
Press the pedal until the machine stops and
then go into reverse by shifting the lever sideways and into position «R»  (☛4.22).
Gradually release the pedal to engage the clutch and then begin moving in reverse.
When the machine has stopped moving, start
reversing by pressing the drive pedal in direction «R»  (☛4.32).
5.4.5 Grass cutting
To start cutting:
– move the throttle to «FAST»;
– raise the cutting deck as high as possible;
– engage the blades (☛4.9);
– start moving forwards on the grass very slowly and with utmost caution, as already
described;
– regulate the cutting height and speed (☛4.8) considering the conditions of the lawn
(the height, density and dampness of the grass).
When cutting on sloping ground, reduce your speed to
ensure safe conditions ( ☛ 1.2 - 5.5).
Whatever the conditions, always reduce the speed if you notice a drop in engine speed
– if you travel too fast compared to the amount of grass being cut, you will not be able
to mow the grass well.
Disengage the blades and raise the cutting deck as high as possible whenever you
need to get past an obstacle.
5.4.6 Emptying the grass-catcher
This operation can only be done with the blades disengaged, oth-
erwise the engine stops.
Do not let the grass-catcher become too full as this may block the collector channel.

							24ENHOW TO USE THE MACHINE
When the grass-catcher is full you will hear a
sound warning. At this point:
– disengage the blades (☛4.7) and the sound
will stop;
– lower the engine speed;
– shift into neutral (N)  (☛4.22 - Mechanical
transmissionor 4.32 - Hydrostatic transmis-
sion) and stop moving forward;
– engage the parking brake on slopes;
– pull out the lever (1) and tip up the grass-
catcher to empty it;
– close the grass-catcher so that it hooks onto
the pawl (2).
5.4.7 Unblocking the collector channel
Cutting very tall or wet grass, particularly at excessively high speed, can clog up the
collector channel. If this happens proceed as follows:
– stop moving forward, disengage the blades and stop the engine;
– remove the grass-catcher or stone-guard;
– remove the grass cuttings; you can reach them from the exit of the collector chan-
nel.
This job must only be performed with the engine turned off.
5.4.8 End of mowing
When you have finished mowing, disengage the blades, lower the engine speed and
ride the machine with the cutting deck raised as high as possible.
5.4.9 End of work
Stop the machine, move the throttle to «SLOW» and turn
off the engine by turning the key to «OFF».
When the engine has stopped, close the fuel stopcock (1)
( if fitted).
To avoid backfire, position the
throttle on «SLOW» for 20 seconds before stopping
the engine.

Always take out the ignition key before leaving the machine
unattended!
To keep the battery charged, do not leave the key in the «ON»
position when the engine is not running.
5.4.10 Cleaning the machine
After use, clean the outside of the machine, empty the grass-catcher and shake it to
remove grass and other debris.
Always empty the grass-catcher and do not leave containers
full of cut grass inside a room.
Clean the plastic parts of the body with a damp sponge using water and detergent,
taking care not to wet the engine, the electrical parts or the electronic circuit board
located under the dashboard.
Never use hose nozzles or harsh detergents to clean the body-
work or the engine!
When washing the inside of the cutting deck and the collector channel, the machine
must be on firm ground with:
– the grass-catcher or stone-guard fitted;
– the operator seated;
– the engine running;
– the transmission in neutral;
– the blades engaged.
Connect a water hose to each of the pipe fit-
tings (1) one at a time and run water through
each one for a few minutes, with the blades
moving.
When washing, the cutting deck should be
lowered right down. Take off the grass-catcher,
empty and rinse it, and then put it in a position
where it can dry quickly.

5.4.11 Storage and inactivity for long periods
If you intend not to use the machine for a long period (more than 1 month), disconnect
the battery cables and follow the instructions in the engine instruction manual.
Empty the fuel tank by disconnecting the tube situated
at the inlet of the fuel filter (1) and follow the instruc-
tions in the engine manual.
Carefully remove any dry grass
cuttings which may have collected around the
engine or silencer to prevent their catching fire
the next time the machine is used!
Put the machine away in a dry, sheltered place and
preferably covered with a cloth (☛8.4).
The battery must be kept in a cool and dry place. Before a long
storage period (more than 1 month), always charge the battery, and then recharge
before using again  (☛6.2.4).
The next time the machine is used, check that there are no fuel leaks from the tubes,
fuel stopcock or carburettor.
5.4.12 Card protection device
The electronic circuit board has a self-resetting protector which breaks the circuit if
there is a fault in the electrical system. This causes the engine to shutdown and is indi-
cated by the indicator light going our ( machine with indicator light) or by the com-
plete shutdown of the control panel ( machine with 6 indicator light control panel).
The circuit automatically resets after a few seconds but the cause of the fault should
be ascertained and dealt with to avoid reactivating the protection device.
To avoid activating the protection device:
– do not invert the leads on the battery terminals;
– do not use the machine without its battery or damage may be caused to the
charging regulator;
– be careful not to cause short-circuits.
