IMPORTANT In order not to compromise
the efficiency of the electromagnetic clutch:
- do not let the clutch come into contact with oil;
- do not spray pressurised water
directly on the clutch unit;
- do not clean the clutch with petrol.
b. Cleaning the exterior
Do not let debris and dried grass
accumulate in the upper part of the
cutting-means assembly in order
to maintain maximum machine
efficiency and safety levels.
To clean the upper part of the
cutting-means assembly:
• lower the cutting-means assembly
completely (position «1»);
• direct an air jet through the apertures in
the left and right safety guards (fig. 36).
7.7
NUTS AND BOLTS
• Keep all nuts, bolts and screws tight to be sure
the equipment is in safe working condition.
8. EXTRAORDINARY MAINTENANCE
8.1 SAFETY RECOMMENDATIONS
You must go to a specialized
Service Centre or contact your Dealer
if the following are malfunctioning:
- the brake
- the cutting means engage
and disengage functions
- switching the drive to forward
or reverse gears.
8.2 CUTTING-MEANSASSEMBLY
8.2.1 Aligning the cutting-means assembly
The cutting-means assembly should be properly
adjusted to obtain an evenly mown lawn (fig. 37).
If mowing is uneven, check the
tyre pressure (par. 6.1.3).
If this is not sufficient to achieve an even
cut, please contact your Dealer to adjust the
alignment of the cutting-means assembly.
8.2.2 Cutting mean
A badly sharpened cutting mean pulls at the
grass and causes the lawn to turn yellow.
All work on the cutting means
(disassembly, sharpening, balancing,
repairing, reassembly and/or replacing)
are demanding jobs that require special
skills as well as special tools. For
safety reasons, these jobs are best
carried out at a Specialised Centre.
Always replace damaged, bent
or worn cutting means, together
with their nuts and bolts, in order to
ensure they remain balanced.
IMPORTANT We strongly recommend
changing all the cutting means at the same
time, especially in the case of uneven wear.
IMPORTANT Always use original
cutting means bearing the code
indicated in the "Technical Data".
Given product evolution, the cutting means
listed in the "Technical Data" table may be
replaced in time with others having similar
interchangeable and operating safety features.
8.3 REPLACING OF FRONT
/ REAR WHEELS
8.3.1 Preparation
IMPORTANT Use a suitable lifting
device, for example a scissor jack.
Before changing the wheels it is necessary
to complete some preliminary operations:
• Remove all attachments.
• Position the machine on a solid
and even surface that guarantees
stability of the machine.
• Engage the parking brake;
• Stop the engine;
• Remove the key from the ignition;
• Position the jack in the lifting position near the
wheel to be changed (par. 8.3.2; par. 8.3.3).
• Check that the jack is perfectly
perpendicular to the ground.
8.3.2 Choice and positioning of the
jack on the rear wheels
Position some wooden wedges (fig. 38.A)
at the base of the wheel (fig. 38.B) next to
the wheel to be changed (fig. 38.C).
For models with rear collection:
• The maximum possible jack height
when closed is 110 mm. (fig. 39).
