– the speed presetting lever (fig. 1 no. 1) is in the stop position;
– the PTO blade rotation lever is in the neutral position (fig. 1 no. 2);
– the air filter is clean (fig. 2 - petrol engine; fig. 3 and 4 - diesel engine), to check the engine lift the machine casing;
– the strainer inside the grass catcher is clean (fig. 5);
– the cutting deck, turbine and grass entry ducts are clean.
Fill the fuel tank using a funnel fitted with a very fine mesh filter.

STARTING THE PETROL ENGINE

Push the throttle to half-way (fig. 1 no. 4).
If the engine is cold, pull on the choke located on the left, by the side of the seat (fig. 1 no. 3). Turn the ignition key
on the instrument panel (fig. 1 no. 8); once the engine starts release it, disengage the choke and place it in the RUN
position, wait a few minutes to warm the engine.

STARTING THE DIESEL ENGINE

Put the key into the ignition switch; turn it to the right to warm-up; when the plug light goes out, turn the key to the
right in the ST position and release it as soon as the engine starts.
To switch off the engine turn the key to the OFF position (fig. 1 no. 8A).

STARTING WORK

Release the cutting deck (fig. 1 no. 9), rev up the engine, engage the PTO lever (fig. 1 no. 2). Gently move the speed
presetting lever (fig. 1 no. 1) and start work.
The two central levers (fig. 1 no. 5) are for steering the machine to the left and to the right; when they are both pulled
backwards together the machine goes into reverse.
When the grass catcher is full, a sensor automatically disengages the blade rotation to avoid blocking up the grass
entry ducts; when the lever (fig. 1 no. 6) is pushed upwards the basket empties automatically (basic version).
Use the 4 pins (fig. 1 no. 10) to adjust the cutting height.

GUIDELINES FOR EFFECTIVE USE

The machine can also be used under harsh conditions without any risk of jamming up. Certain measures must be
taken.
1. Before starting work check that the deck and the entry ducts are perfectly clean without any dried grass or soil.
2. Check the terrain before mowing, that there are no stones, sticks or foreign objects.
3. While mowing keep the engine at maximum revs., adjust the speed to suit the height of the grass. Be careful
when coming across tall thick clumps of grass, slow down when required.
4. Sharpen the lawnmower blades regularly; the cut will be better and the engine will not have to work so hard.
5. After emptying the grass from the catcher, engage the blades a few metres before reaching the grass to be
cut, this will clean the deck and the grass entry ducts.
6. Keep the grid inside the catcher clean.
7. If the grass is wet or very tall, do not cut in the lowest position, but at a mid-way height.
8. Check the tension on the belts that work the turbine and the deck; using the adjuster if necessary (fig. 6).
9. Check that the blades are not worn, especially the fins that push the grass into the entry duct.
10. Check the vanes on the entry turbine for wear.
11. Check that no foreign objects have clogged the turbine.
12. Check the rotation of the duct inside the grass catcher.
13. Check that the blades disengage automatically when the grass catcher is full; to do this, turn the ignition key,
turn on the panel without starting the engine, engage the PTO blade rotation lever (fig. 1 no. 2) and touch
by hand the vane fitted to the duct sensor (fig. 7). The PTO should now disengage.
14. Check the engine revs.
15. Always mow with the engine at maximum revs; if the engine revs drop, slow down for a while, to allow the engine
to reach the right level again.
16. Check that the blades are fitted properly.
17. On the 126 cm Professional deck the blade terminals that are already equipped with holes can be blocked with
mild steel screws. The rigid terminal gives a greater push to the grass inside the grass entry duct.
18. Check that the entry duct fits correctly and is aligned inside the turbine.
19. If the grass is very tall and wet, the exhaust gas deviator can be used (fig. 8), to prevent the turbine becoming
blocked and help the grass entry; under normal conditions this device should not be used.
