■) The machine VIBRATES more than expected
-) Missing, broken, bent blades => see CHAP. 7c 4).
-) Loosened fixing bolts => Tighten immediately and consider a total replacement of the fixing
nuts, if they have lost their locking ability (M10 self-locking nuts, cone-lock type).
-) Blades and bolts are in good conditions, rotor bent due to the hits received => total rotor
replacement carried out by an authorised workshop.
-) Loosened engine plate => tighten the 4 bolts fixing the engine to the plate and the 4 bolts fixing
the plate to the rest of the frame.
■) The machine makes more NOISE than expected
-) If the noise does not come from the rotor but from the machine rear part => lubricate with WD
40 the hoses containing the contrast springs of the belt tensioners under the engine.
-) If the noise comes from the hydrostatic transmission => wait until the machine has cooled down
and check if the noise goes away; if not, inspect and then completely replace the oil at an
authorised workshop.
-) Exhaust issues => check the tightening of the band holding the muffler on the manifold.
■) The engine produces anomalous SMOKE (it burns oil)
-) The engine burns oil because the machine is used uphill too much => reduce the exposure of
the engine heads downstream, and alternate uphill cutting operations with downhill ones and
"recovery" times on flat surfaces more often.
-) The engine oil level is too high => proceed as described in CHAP. 7b, do not fill over the
indicated MAX limit.
■) The ENGINE gets too hot
-) Presence of debris all around the engine and especially in the upper part, close to the flywheel
cover => Free all engine surfaces from debris build-ups, especially the upper part.
-) Oil quantity in the block is too low => fill up immediately as described in CHAP. 7b and in the
engine manufacturer manual.
■) CUTTING RESULTS are uneven
-) Blades partially broken, worn or missing => Proceed as described in CHAP. 7c 4)
-) The mowing deck is clogged => It is necessary to start working with a clean mowing deck
internal volume, as described in CHAP. 7c 3)! Wash using the supplied sleeves. The cutting quality
strongly depends on the free volume around the rotor!
-) The engine (and, therefore, the rotor) is not turning at its maximum RPMs => Bring the throttle
to the maximum during cutting operations, so to have an ideal impact speed.
-) The forward speed and/or cutting height are not proportional to the type of terrain and density
of the vegetation to be cut => decrease the speed and raise mowing deck until an ideal cut is
achieved. If necessary, pass on the vegetation cut once more.
-) If the vegetation cut is asymmetrical, it is likely that the rotor casing received some hits which
have bent the lifting rods or the hinge on which it rotates, tilting it on one side => have the
machine checked by an authorised workshop.
-) If the vegetation cut is asymmetrical and the mowing deck did not receive hits => check the tyres
pressure, looking for possible differences between left and right wheels.
-) If on an exclusively grassy terrain the vegetation cut is too coarse => INCREASE the travel speed
lowering the rotor height, so to clog the casing more and increase the grinding before the
vegetation is discharged on the ground. On the other hand, IF THE TERRAIN HAS BRANCHES OR
SHRUBS, these precautions are counterproductive.
