CAUTION!
- Disconnect the plugs 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 manual; in all cases the oil
must be changed after the first 20 working hours, and then every 100 hours or every season,
together with the oil filter (fig. 12, oil drain plug; please, remove the tap while keeping the piece
connected to the engine blocked with a key). 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 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 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).
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 (fig. 9, ref.3). 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 (fig. 9).
CAUTION!
Tighten the fixing screw (fig. 9, ref. 3) firmly. Always replace damaged or crooked blades; never attempt
to repair them! ALWAYS USE ORIGINAL BLADES!
