Refer to online Use and Maintenance Manual PDF which can be downloaded from 

Before starting up the engine, always check that:
the travel lever is in the idle position (fig. 3);
the engine oil level is correct (fig. 4);
the engine cooling intake grilles are clean (fig. 7);
air filter is clean (fig. 8 – 8A).
the mowing deck is clean;
the hydraulic motor fins are clean (fig. 5);
the blades are sharp and firmly fastened in place;
the screw in the centre of the blade hub is safety tightened (no. 3, fig. 9)
the oil in the hydraulic axle is at the correct level (fig. 5); the correct level is 12 mm underneath the bottom of the tank (fig. 6);
Fill the fuel tank using a funnel with very fine filter (no. 4, fig. 10). Adjust the seat by using the lever fig. 11.

Push the throttle half way in (no. 5, fig. 3)
If the engine is cold, use the choke (no. 6, fig. 3). Turn the ignition key (no. 1, fig. 1).
Once the engine has started, turn off the choke and wait for a few minutes to allow the engine to warm up.
N.B. When travelling with the mower from one place to another, you are advised to keep the cutting deck at the maximum height setting.

To switch on the headlamp, put the ignition key in the second position (fig. 18, position A).
IMPORTANT: It is necessary to switch on the headlamp once the engine has started up to avoid battery discharge.

Choose the desired cutting height by means of the lever (no. 8 fig). 2. Suitably accelerate the engine and engage the PTO lever using the switch on the dashboard (fig.1, no. 6). Gently operate the forward travel lever (no. 2, fig. 3) and start work. To stop, return the forward travel lever to the stop position.  The lever (no. 2, fig. 3) is also used to reverse. When it is moved back, the machine moves backwards; always operate it gently.

The front brake (4, fig. 1) must be used only as emergency brake, sloping down in order to avoid the machine sliding. If you use it together with the differential lock, the machine is steadier, above all in slope conditions. In normal conditions, to slow down and brake you need only to use the feed lever.
In order to adjust the cables you have to operate on the adjusters fig. 26.

To engage the parking brake lift the loop up 10, fig. 3 and hook the lever. To adjust the parking brake use the register (fig. 5).

The differential locking pedal is the one indicated in fig. 1 no. 5.
Press the differential locking pedal in case of driving-wheels skidding. It is advisable to use the diff lock on steep downward slopes to keep both driving-wheels in traction. Attention! Do not use the differential locking when bending.
In case of disengagement, keep the coupling and the drive-chains (fig. 27) lubricated with grease 

The machine is equipped with the an hourmeter with three different functions:
1) It always shows the number of hours worked, even when the key is not inserted.
2) It displays the number of hours to the next engine oil change (OIL CHANGE IN...HS). The first oil change must be carried out after the first 20 working hours than every 100 working hours. The indicator “OIL CHANGE” flashes automatically when it is necessary to change the oil.
3) It displays the number of hours to the next lubrication (LUBE IN...HS). Lubrication must be carried out every 50 working hours. The indicator “LUBE” flashes automatically when lubrication must be carried out.
By pushing the white button you can choose the function to be displayed on the hour meter (fig. 1, no. 2).

1) Never strain the engine: when fumes are emitted from the exhaust it means that it is being strained. Slow down.
2) Do not leave the machine out in the rain.
3) Frequently sharpen the mower blades: the cut will be better and the engine will not be strained as much.
4) Check the land before mowing to make sure that there are no stones, sticks or foreign bodies.
5) Keep the engine at peak rpm during mowing, adjust the speed according to the height of the grass.
6) Keep the grilles above the engine and the cooling fins of the hydraulic motor (fig. 4 – 5) clean.

The cutting position is adjusted using the lever (n. 8 fig. 2).
The deck can be set in 4 different cutting positions from 35 to 80 mm and one travel position in which the blade disengages automatically.
In case of uneven ground, humps or dips, the deck should be kept in the highest cutting position to prevent knocks by the blade.

If possible, steep slopes must be mown in the up/down direction, taking great care when turning that the wheels upstream do not strike obstacles (stones, branches, roots, etc.) which might cause the machine to overturn, or lead to loss of control.
Assess the conditions and take care if the ground and grass are damp since the machine might slip. Downhill, set off at low speed and do not pass over dry or cut grass since the wheels lose grip; please remember that if you engage the differential lock and eventually the front emergency brake (4, fig. 1) the machine is steadier.

Remember that the engine will stop whenever:
The operator gets up from the seat. The engine will not start up if:
The blade is engaged.
Nobody is sitting in the driver’s seat.
If the forward lever isn’t at STOP setting.
If the mower deck isn't in the highest transfer position.

Disconnect the plug before performing any cleaning, maintenance or repair operation. Always wear suitable clothing and working gloves.
When the machine or part of it is lifted to carry out maintenance operations, always remember to use suitable fixing tools such as holders and safety locks.
When carrying out maintenance operations and/or when the machine is tilted without safety locks or supports, never leave it unguarded in places where inexperienced people  and children could have easy access to it.
Protect the environment: carefully dispose of used oils, petrol and any other pollutant product!
Effective maintenance and correct lubrication help to keep the machine fully efficient.

For the lubrication intervals, follow the instructions provided in the engine handbook; in all cases the oil must be changed after the first 5 working hours, and then every 50 hours or every season, together with the oil filter (fig. 12, oil drain plug; please, use a second key in the fixing part). Replace the engine oil filter (fig. 13). The first precaution is to ensure that the engine is correctly serviced with the air filter, cooling fins and cylinder head clean and the oil at the correct level. Check the air filter every 4 hours, or even more often in very dusty environments. Check the engine cooling intake grille (fig. 4).

With the engine cold, check the expansion tank (fig. 5); it must be empty. Clean the hydraulic motor cooling fans often, every 4 working hours in summer when conditions are very dusty (fig. 5). Replace oil after the first 50 working hours, then every 200 hours, use 10W60 engine oil; quantity: 1.85 litres, for replacing follow the instructions given:
1) remove the two plugs fig. 14;
2) remove the plug using a screwdriver fig. 15;
3) screw the two caps fig. 14 (tightening torque 13-17 Nm);
4) add oil, fix the cap fig. 15;
5) make sure the expansion tank is empty, the correct oil level is 12 mm underneath the bottom of the expansion tank, fig. 6.

Grease every 20 hours:
  • the wheel pivots (fig. 16)
  • the bushing in the belt stretcher of cutting deck- engine belt (fig. 16/A).
  • the forward levers joints (fig. 20).
  • the rack steering joints after having removed the board from the steering column (fig. 20A).

Check the air filter every 4 hours, or more frequently if working in a very dusty environment (fig. 8 – 8A).

A blunt blade tears the grass, leaving it unattractive. The cutting edges of both blades must be sharpened. To remove a blade, take hold of it firmly, wearing work gloves, and unscrew the central screw,  remembering that the screw has a right-   thread (3 fig.  9).  Sharpen both cutting edges    using a medium-grain grinding wheel and check that the blade is balanced by standing it on a round bar inserted in the central hole. Fit the two cutting blades following the diagram in fig. 9.

Tighten the fixing screw (3 fig. 9) firmly. Always replace damaged or crooked blades; never attempt to repair them! When fitting, always follow the diagram (fig. 9). ALWAYS USE ORIGINAL BLADES! If they are worn they can be turned round since they have two cutting edges. Always check that the blade bolts are not worn or damaged.

Levelness of the cutting deck is essential in order to obtain an evenly mown lawn.
Park the mower on a flat surface and check that the tyre pressure is correct. Adjust the 4 adjustment devices (fig. 17 – 17A), so that the edge of the cutting plate is at the same distance from the floor, 110 mm, on both sides (with the operator sitting on board and the cutting deck in the position no. 1 (fig. 18/A). If you are unable to level off the deck, contact an Authorised After-Sales Service Centre.

To adjust the belt tension operate on the register (fig. 18). If the belt becomes twisted or comes off, make all the checks and adjustments stated below, keeping the deck at the lowest position. Take care when positioning the belt guides; move them towards the belt, checking the deck at the various height settings (fig 19).

These belts are self-adjusting and do not require any adjustment.  Simply check the spring tension.  To replace the belts, release the tension spring (fig. 21).

Rotation is started and stopped using the on/off switch (no. 6, fig. 1).
When rotation is engaged the engine must be running at medium rpm and the machine must not be in the grass for cutting. Never start the blades with the engine at maximum rpm. The machine is equipped with an electromagnetic clutch which also brakes the blade during disengagement. The blades are also disengaged automatically when the cutting height adjuster lever is moved to the highest position.
CAUTION: for safety reasons if the operator pushes down the height adjustment lever from the highest position with the PTO button engaged, the blades do not start automatically. To start the blade the PTO button must be switched off and switched on again.
The blade must stop within 5 seconds, if this is not the case, adjust the 3 nuts of the electromagnetic clutch, placing a 0.3 mm feeler gauge under the brake plate. N.B. This operation must be carried out by an authorized after-sales service center.

The movement is transmitted from the motor to the hydraulic transmission and to the blades  by means of two v-belts. Replace the belts as soon as they show signs of wear! Their replacement and subsequent adjustment are fairly complex procedures and must be carried out by an Authorised After-Sales Service Centre. For cutting deck drive belt, the belt guide beside the deck pulley has to be removed (fig. 19); release the belt stretcher spring (Fig.20). ALWAYS USE ORIGINAL BELTS!

On both sides of the differential lock axle there are two chain tensioners. To regulate them slightly unlock the two nuts (fig. 28, ref. A) and use the screw (fig. 28, ref. B). CAUTION: In order not to overload the transmission, do not tension the chain. The chain should move about 1 mm.

The traction release device is located at the back of the machine (fig. 22); if the machine breaks  down, to allow it to be towed or moved by hand, move the lever to idle position (B, fig. 22). In the position (A) shown in fig. 22 the machine is in working condition.

The electrical system is protected by a fuse which cuts out the entire electrical system if blown. After finding and repairing the fault, replace the fuse with another of the same rating. Never replace the fuse with one of a different rating. The electrical system fuses are on the left-hand side of the steering wheel (fig. 23). If the problems persist after all the procedures described above have been carried out, contact the Authorised After-Sales Service Centre. Never attempt to make difficult repairs unless you have the necessary equipment and technical expertise.

Take care not to reverse the battery polarity.
Never operate the mower without the battery, since it is equipped with a charge regulator.
Take care not to cause short-circuits.

Adjust the device (fig. 24) by loosening the counter-nut and acting on the central screws.

To adjust the forward and reverse travel speeds, use the screws (A, fig. 25) if the forward lever automatically returns to zero adjust the self-locking nut (B, fig. 25).

After mowing, disengage the blades and drive back to base with the cutting deck in the highest position.
To stop, move the travel lever to the STOP position (2, fig. 3), set the throttle lever on the minimum rpm, switch off the engine by turning the key (1, Fig. 1) and lower the deck to the lowest position.

Clean the outside of the mower after each use. Do not use high pressure washers or water blasters!

Store the mower in a dry place, away from atmospheric agents, and preferably cover with a sheet. If the mower is not going to be used for a long period (over 1 month), disconnect the red battery cable (fig. 23) and follow the instructions given in the engine manual. Also lubricate all of the articulated joints. Regularly check that the battery voltage does not drop below 12 volts. If it does, recharge the battery. Use the preservative additive for unleaded petrol. If the machine is to be out of use for more than 30 days, drain the fuel from the engine to prevent sticky deposits from forming in the fuel intake system or in vital parts of carburettor. To protect the engine we advise you to use the Briggs &  Stratton fuel additive, available from all Briggs & Stratton authorised services centres. Add the  additive to the fuel in the tank or in the fuel container. Run the engine a little to circulate the additive through the carburettor. The engine and carburettor can be stored for up to 24 months. NB.: If no additive are used or the engine is running on petrol which contains alcohol, drain the fuel tank and run the engine until there is no fuel left.

If the machine is transported on a truck or trailer, lower the cutting deck, engage the parking brake and fasten the machine to the truck with ropes or strops.
