MAINTENANCE AND LUBRICATION
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!
- Efficient maintenance and correct lubrication help to keep the machine in perfect working
order.
ENGINE
For the lubrication intervals, follow the instructions provided in the engine handbook;
the oil must in any
case be changed after the first 20 working hours,
using AGIP SAE 30 engine oil. To remove the oil,
cut the plastic strapping that keeps the oil discharge pipe attached to the frame (fig. 20B) and position a
container to collect the exhaust oil. Then unscrew the tap at the end of the pipe using a lock key. Change
the oil filter (fig. 10).
FINAL DRIVE GEARBOX
Check the oil level every 100 hours by unscrewing the cap (fig. 11, ref. A); if necessary top up with
80W90 (API GL-5) gearbox oil. To drain the oil unscrew the cap (fig. 11, ref. B). Change the oil every
1000 hours. Quantity 1.9 litres (fill through the tap fig. 11A).
HYDRAULIC MOTOR
Check the level in the expansion tank when the motor is cold. It should come up to the level notch (fig.
3). If necessary, add AGIP SAE 15W50 or 20W50m oil. Change the oil every 200 working hours. To drain
the oil, unscrew the cap (fig. 4); pour into the tank. Keep the fins and coil of the hydraulic motor (fig. 3A
and 7) thoroughly cleaned. Quantity 1 litre.
AIR FILTER
Check the air filter every 4 hours, or more frequently if working in a very dusty environment (fig. 6).
Check the air intake grid for engine cooling (fig. 5). The external and internal grids must always be kept
clean to avoid blocking the air flow needed for the engine cooling. Keep the engine compartment, the
hydrostatic transmission and the intake grid clean.
CHECKING THE BLADES AND DECK
A blunt blade tears the grass, leaving it unattractive. The blades cutting edges must be always
sharpened. To remove a blade, take hold of it firmly, wearing work gloves, and unscrew the central
screw, remembering that the screw is located on the right. 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.
CAUTION!
Tighten the fixing screw firmly. Always replace damaged or crooked blades; never attempt to repair them!
ALWAYS USE ORIGINAL BLADES!
110 MP CUTTING DECK
This cutting deck with 3 blades has a cutting width of 1100 mm. It has two functions: rear discharge and
mulching. If you want to change from rear discharge function to mulching function you simply have to
use the lever. It is namely not necessary to change the blades (fig. 26 – 27). The cutting height can be
adjusted electrically using the button on the dashboard (fig. 36).
