CAUTION!
- 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.
ENGINE
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).
HYDROSTATIC AXLE
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.
LUBRICATION
Grease every 20 hours:
- the wheel pivots (fig. 16)
- the bushing in the belt stretcher of cutting deck- engine belt using remote grease gun (fig. 16/A).
- the blade shaft bearings using remote grease gun (fig. 20).
- the rack steering joints after having removed the board (fig. 20A).
AIR FILTER
Check the air filter every 4 hours, or more frequently if working in a very dusty environment (fig. 8 – 8A).
CHECKING BLADES AND CUTTING DECK
A blunt blade tears the grass, leaving it unattractive. The cutting edges of both blades must be sharpened. To remove the
complete blade, take hold of it firmly, wearing work gloves, and unscrew the screws (no. 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.
CAUTION!
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.
ADJUSTING THE CUTTING DECK
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.
