CAUTION: Do not insert the cutting blades with the engine running at maximum revs. The engine
has to run at half speed. Insert the cutting blades at half speed and at some distance from the
grass to be cut.
IMPORTANT
1) Adjust the travel speed in order to avoid overloading the deck when at work and cut with the
engine at maximum revs.
2) Always keep the blades sharp.
In case of wear, sharpen or replace them as required.
Gently press the speed selection pedal (fig.1, n.1) and start work. Push the pedal to position A to
travel forward and to position B to travel in reverse. If the pedal is released, the machine
immediately stops. Lever (fig.3, n.7) is the parking brake; in the "P" position (fig. 2) the parking
brake is engaged.
When the grass-catcher is full the blades automatically disengage. The grass-catcher is equipped
with an inner moving sensor that automatically disengages the blades when the grass-catcher is
full (fig.38). The grass-catcher has therefore to be emptied. The grass-catcher can be emptied
directly from the driver's seat using the buttons (fig. 5, n.12 to lift the grass-catcher and n.13 to
empty the grass-catcher). The grass-catcher door automatically opens. The grid inside the grass-
catcher must always be kept clean to improve grass collection and to prevent clogging (fig. 7).
During summer and in very dusty environment it is recommended to mount the plastic protection
plate (fig. 7A) inside the grass-catcher. This plate and the necessary screws are delivered with the
machine.
GRASS-CATCHER CLOSING
The grass-catcher can be checked opening the door (fig. 8, A). The closing can be regulated (fig.
8, B). The grass-catcher door opens automatically when the operator uses the button from the
driver's seat. To keep the grass catcher door open use the rod (fig.9, A). CAUTION: Do not
engage the blades when the grass catcher door is open.
GUIDELINES FOR EFFECTIVE USE
1. Check the condition of the ground before mowing. Make sure there are no stones, sticks or
other foreign objects.
2. When mowing, keep the engine at full revs and adjust the speed to suit the height of the
grass. Take care when you come to thick clumps of tall grass; slow down if necessary.
3. Sharpen the mower blades frequently; the cut will be better and the engine will be under less
strain.
4. Engage the blades a few metres before you come to the grass for cutting.
5. Always keep the engine at full revs when mowing; if the engine slows down, decelerate for a
moment to allow the engine to recover r.p.m.
6. For best lawn appearance, alternate one longitudinal and one transverse cut, both at the
same height.
7. If the duct tends to become clogged with grass, reduce the travel speed since it may be too
high for the lawn's condition. If the problem persist, probable cause are blunt blades, dented
fins profile, slack belt or clogged grass catcher grid.
8. If the grass is very long, it is best to cut in two passes, the first with the blades at the highest
level, perhaps working on reduced width, and the second at the final height required.
9. Take great care when cutting close to bushes and low kerbs which might damage the edge of
the back and the blades.
10. When you finish work, engage the parking brake and always turn off the petrol tap (fig.3,
no.7).
MOWING POSITION
To adjust the cutting height use the button (fig.2 n.4). On rough or uneven ground, always work
with the deck in the highest cutting position in order to avoid knocks on the blades.
