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 unattended 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; the oil must in any
case be changed after the first 20 working hours and then every 100 hours, using SAE 30 engine
oil. To remove the oil unscrew the tap (fig. 20A). Change the oil filter (fig. 10).
WHEEL 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 Lt. (fill through the vent 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 15W50 or 20W50 oil. Change the oil every 200 working hours. To drain the oil,
unscrew the cap (fig. 4) and pour into the tank. Keep the fins and coil of the hydraulic motor thoroughly
cleaned (fig. 3A – fig. 7). 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 engine cooling grid (fig. 5). Both the inner and outer 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. The engine cylinder cooling fins are easily accessed to for
cleaning by loosening the screw (fig. 6, A) on both sides.
CUTTING DECK AND BLADES
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. 1C, no. 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. 13).
IMPORTANT: Firmly tighten the fixing screw (fig. 1C, no. 3). Always replace damaged or crooked blades.
Never attempt to repair them! When fitting, always follow the diagram (fig. 13). ALWAYS USE ORIGINAL
BLADES! If they are worn they can be turned round since they have two cutting edges.
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. Use both the right and left adjusting screws (fig.
14) and those located on the front arms of the cutting deck (fig. 14A) to set the cutting deck border at the
same distance from the floor, that is 210 mm (fig. 24 – fig. 24A) on both sides with the operator sitting on
board and the cutting deck in the highest cutting position. If you are unable to carry out this adjustment,
contact an authorised service centre. A baffle is delivered together with brush-cutter (fig. 15) to be
