MAINTENANCE AND LUBRICATION
CAUTION
Remove the key and disconnect the plug before performing any cleaning, maintenance or repair operation.
Always wear suitable clothing and working gloves.
IMPORTANT!
Protect the environment: carefully dispose of used oils, petrol and any other pollutant product!
Efficient maintenance and correct lubrication help keep the machine in perfect working order.
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 10W30 engine oil; quantity: 1.85 lt, 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 N.m);
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.
FRONT WHEEL AXLE
Grease the wheel pivot pins (fig. 16) every 20 hours.
Lubricate the steering joints.
Lubricate the bushing in the belt stretcher of cutting deck- engine belt (fig. 16/A).
AIR FILTER
Check the air filter every 4 hours, or more frequently if working in a very dusty environment (fig. 8).
CHECKING THE BLADES AND CUTTING DECK
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-hand 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.
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 - 17/A), so that the edge of the cutting plate is at the same distance from the floor, 100 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.
