Translation of the original instructions

- the oil is black;

- the oil has a whitish colour (it is contaminated with water);

- there is black coloured residue (partial oil deterioration).

To remove the oil undo the lower oil reservoir plug (fig. 20). To fill it in, unscrew the upper cap (fig. 6, ref. B). Pay

attention to possible impurities, which may get into the circuit, causing serious problems to your machine.

When you change the hydraulic oil, you must also change the two oil filters (fig. 46, ref. B); pay attention to the

filtration level of each filter (10 and 60 micron) and not to mix the filters up. On the dashboard there is a warning

light connected to the filter blocking sensor that shows when the filter has to be replaced.

Do not increase the drive wheels hydraulic system pressure over 280 bar; the hydraulic pump and the hydrostatic

engines on the wheels may be damaged.

To regulate the cutting deck and the grass catcher hydraulic pressure you must work on the screw with jam nut

located on the hydraulic distributor. This operation must be carried out by an Authorized Service Centre.

155 cm CUTTING DECK GEAR BOXES

Use synthetic oil LSX 75 W 90 (API GL4 + GL5; API MT1 and PG2), 1.550 litres, to be changed every 300 hours.

The oil level plug is positioned over the gear boxes.

If you notice any leakage, check and replace the oil seals to avoid the deterioration of the entire transmission.

GREASE LUBRICATION POINTS

Find the lubrication points following the scheme (fig. 3 no. 7). Grease the rear axle pivots, the pedals, the PTO

transmission belt guide pulley, the pivot connected to 2 points joint of the cutting deck, the grass catcher lifter arms

and the turbine shaft every 40 hours.

EMERGENCY AND PARKING BRAKE OIL

Every 50 hours check the brake oil level in the reservoir on the left side of the driving seat (fig. 40). If necessary,

add brake oil DOT4 (total quantity 0.5 litres). Periodically check the braking system to make sure there are no

leakage.

Whenever it is necessary, carry out the air bleed procedure. If you have the proper tool, connect it at the place of

the reservoir cap. If you have to carry out the bleed without the proper tool proceed as follows:

1) Put the oil into the reservoir.

2) Press the emergency brake pedal 3 times (fig. 1 no. 3): keeping the pedal pressed, slightly unscrew the drain

plugs on the calipers to let the air out.

3) Repeat the procedure twice, until the circuit gets under pressure when pressing the pedal.

4) Attention, the brake pedal has to have a little clearance to prevent that the circuit is steadily kept in pressure,

which would damage the brakes.

NOTE: Use the brake pedal only in case of emergency. To stop, just release the feed and reverse pedal.

SHARPENING THE BLADES

For the cutting deck check and maintenance proceed as follows:

1) lift the cutting deck hydraulically;

2) release the two side shock absorber (fig. 11);

3) lift the cutting deck by hand and hitch it with the special lever (fig. 22).

You do not need to release the universal joint nor the deck loading duct. Before starting the machine, make you

sure that the universal joint is well connected and that the stop push button is protruding.

A blunt blade pulls at the grass giving it an unsightly appearance, the cutting edges of the blades must therefore be

kept sharp at all times. As the blades wear they lose their cutting efficiency and tend to become unbalanced,

causing the lawnmower to vibrate; sharpen both blades uniformly.

When you substitute the blades, it is compulsory to substitute also the screw and respective nut (fig. 23). Do not

lock the blade ends: they must be without play, but free to float if they hit against something.

To remove a blades’ disc, hold it firmly using safety gloves and unscrew the fixing plate and the central screw.

Caution: the right blade central fixing screw has a left-handed thread (fig. 23).

Caution! Always replace damaged or bent blades; never try to repair them! ALWAYS USE ORIGINAL BLADES!

ADJUSTING THE CUTTING DECK

An even deck is essential for achieving a uniform cut over the whole lawn.

With the lawnmower on a flat surface, check the tyre pressures, check the tension of the two deck floating springs

(fig. 24) and act on the adjusting screw if necessary. If a satisfactory parallel set-up cannot be achieved, contact an

Authorised Service Centre. The two deck floating springs also give the drive wheels a better grip, especially on

slopes.

To remove the deck from the mower, undo the two side brackets (fig. 11) and the two pins (fig. 25).

Attention! When the pins are unhooked, please remember to keep the two cutting deck lifting arms pressed

strongly, because they jump up and can be very dangerous.

Unhook the two lateral springs on the grass loading duct and pull forward the whole cutting deck, unscrew the

loading duct from the turbine. Caution! When refitting the deck always remember to reconnect the universal

joint, the loading duct must be screwed for 2 complete turns and does not have to hit the turbine wheel.
