CUTTING POSITIONS
The cutting position is adjusted using the lever 8 fig. 2.
The plate can be set in 4 different cutting positions from 35 to 100 mm.
In case of uneven ground, humps or dips, the plate should be kept in the highest cutting position to prevent
knocks by the blade.
SPECIFIC MAINTENANCE
COMPULSORY - Before every use make sure that the intake zone for the cooling and the
*
clean. OTHERWISE, THE WARRANTY WILL BE NULLIFIED.
*The engine
Consult the maintenance manual, herewith attached.
*The grass-cutter lawn mower
After every use, clean with care the cutting-carter and remove from the engine possible vegetable residues.
Check the cutting-blade; it must always be very sharp, to obtain an as much as possible clean cutting, so a better
capability of your pruning saw.
Attention: if you sharp the cutting-blade, check its stability. Moreover, every 25 working hours, lubricate the
bearings, the axles. Often check the bolts screwing up in general.
MAINTENANCE AND LUBRICATION
CAUTION
Disconnect the plugs 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.
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. 7).
HYDROSTATIC AXLE
With the engine cold, check the expansion tank (fig. 7); it must be empty.
Clean the hydraulic motor cooling fans often, every 4 working hours in summer when conditions are very dusty
(fig. 8).
Replace oil after the first 50 working hours, then every 200 hours, use 10W30 engine oil; quantity: 1.85 l, for
replacing follow the instructions given:
1) remove the two plugs fig. 10;
2) remove the plug using a screwdriver fig. 11;
3) screw the two caps fig. 10 (torque 13-17 N.m);
4) add oil, fix the cap fig. 11;
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 front wheel fig. 12 every 20 hours.
Lubricate the handlebar joints and the cables.
AIR FILTER
Check the air filter every 4 hours, or more frequently if working in a very dusty environment (fig.2 n°15).
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.
