The throttle is controlled by the lever (1) and positioned as shown on the relative plate. Some models have a fixed speed, and therefore no need of a throttle.

Blade brake
The blade brake is controlled by the lever (1) which must be held against the handle for ignition and during lawnmower operations.
The engine stops when the lever is released.
STOP14356687/2
OPC (Operator Presence Control) lever release: engine stop.

IMPORTANT – The blade must stop within a few seconds of when the lever is released; if you notice that more time is required for it to stop, contact a Specialised Centre immediately.

Drive lever (if provided)
On power-driven models, pull the lever (1) against the handle for forward movement.
The lawnmower stops moving forward when the lever is released.
The engine must always be started with the drive-off.
Transmission is active.

Cutting height adjustment
The cutting height is adjusted by the specific lever (1).
DO THIS WHEN THE BLADE IS STOPPED.

GRASS CUTTING

Fastening the grass-catcher
Lift the stone-guard and fasten the grass-catcher (1) correctly as shown in the illustration.

Engine ignition
During ignition, follow the instructions in the engine manual.

Manual ignition models (“I”)

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 (“III – “IV”)

• 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).

Grass cutting
The appearance of the lawn will improve if you alternate cutting in both directions at the same height.
If there is a grass-catcher with contents indicator device (if applicable): while working, with the blade in motion, the indicator remains lifted as long as the grass-catcher is able to hold cut grass; when it lowers, it means that the grass-catcher is full and it must be emptied.

Emptying the grass-catcher
When the grass-catcher is too full, grass is no longer collected efficiently, the sound of the lawnmower changes and the grass-catcher is no longer inflated by the air flow created by the blade.
To remove and empty the grass-catcher,

• stop the engine and wait for the blade to stop;
• lift the stone guard, grasp the handle and remove the grass-catcher keeping it in an erect position.

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 proceeding any further.

Lawn care recommendation
Each type of grass has different features and may thus require different ways to care for the lawn; always read the instructions on seed boxes for mowing height for the growth conditions in the work area.
Keep in mind that the 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:

• too low a cut causes grass tears and uprooting, with a “spotted” aspect;
• in the summer, cutting must be higher to avoid the ground from drying;
• do not cut wet grass; this could reduce blade efficiency due to sticky grass and tear the lawn;
• for particularly high grass, initially mow at maximum admitted machine height followed by a second mow after two or three days.

ROUTINE MAINTENANCE

MPORTANT – Routine and accurate maintenance is essential in maintaining original machine safety and performance levels..
Each adjustment or maintenance operation must be done with the engine stopped, after removing the spark plug cap.
Store the lawnmower in a dry place.

1. Wear sturdy work gloves before cleaning, maintaining or adjusting the machine.
2. Accurately wash the machine with water after each mowing, and remove grass debris and mud accumulated under the chassis to prevent it from drying and causing problems the next time the lawnmower is used.
3. Use the specific attachment for the water hose to clean the internal parts of the lawnmower (if provided). Place the machine in a flat firm surface, select the lowest cutting height and always stand behind the lawnmower handle when cleaning
4. The paintwork on the inside of the chasis may peel off in time due to the abrasive action of the cut grass; in this case, intervene promptly by touching up the paintwork using a rustproof paint to prevent the formation of the rust that would lead to corrotion of the metal .
5. If accessing the lower part is necessary, only tilt the machine on the side indicated in the engine manual, following the relevant instructions.
6. Do not drip petrol onto the plastic parts of the engine or the machine to prevent damaging them and remove all traces of spilt petrol immediately.
   The warranty does not cover damage to plastic parts caused by petrol.

Blade maintenance
Each adjustment made to the blade is best if done at a specialized Centre that has the most appropriate tools.
On this machine must be used blades with code shown in the table on page 2.
Given product evolution, the above-mentioned blades may be replaced in time by others, with similar interchangeable and operating safety features.
Reassemble the blade (2) with the code facing the ground, following the steps indicated in the illustration.
Tighten the central screw (1) using a torque wrench set to 35-40 Nm.

Battery recharging (where applicable)
Electric key ignition models

To recharge a flat battery, connect it to the battery charger (1) following the instructions in the battery maintenance manual.
Do not connect the battery charger directly to the engine terminal. It is not possible to ignite the engine using the battery charger as a power source, as it may get damaged.
If you do not use the lawnmower for a long period of time, disconnect the battery from the engine wiring, making sure the charge level is good.

Electric push-button ignition models
Read the engine instruction manual for instructions regarding autonomy,recharging, reinstating and maintenance of the battery.
