INSPECTION OF ROTOR BEARINGS
Spin the rotor shaft by hand and feel any irregularities in the bearings. Moreover, try to move
the axle from side to side to detect any gaps. If either or both of these occur, remove the axle
caps to closer inspect the bearings. Replace if necessary
INSPECTION OF WHEEL BEARINGS
First make sure that all the wheel nuts / bolts are securely tightened; Jack up one side of the
mower so that one of the wheels is just above the ground. Spin the wheel by hand and check
the wheel placement. In order to check bearings, try to move the wheel from right to left to
feel any gap. Replace worn bearings.
GREASE 50MM TRACTION COUPLING
Check the link to see signs of damage or wear, spin coupling 36 degrees and check if the bush-
ings are not worn. Replace damaged and / or worn parts. Lubricate the coupling regularly.
MAINTENANCE OF KNIVES
The mower is equipped with knives made to last for a long time. If the blade becomes loose
or broken, it is important to replace it immediately. If there is a possible imbalance, which is
very serious, then the blade should be changed and the blade on the opposite side of the
rotor must be controlled for current damage and wear. If it is partly or completely worn out,
it should be replaced to maintain the correct weight balance. When the first edge is getting
blunt, the whole set should be reversed or replaced. Using dull blades will reduces the cutting
efficiency and increases fuel consumption. Replacing the blades is instructed as follows:
A) Ensure that the engine is off and the blades are not rotating. Turn off the fuel valve and al-
low the engine to cool for five minutes. Remove the spark plug to make sure the engine does
not start.
B) Raise mower to its maximum cutting height.
C) Raise gently the drawbar to a slightly inclined position so that the height adjustment hinge
may bear some weight.
D) Loosen and remove the bolts.
E) Replace the blades (note the direction of rotation).
F) Replace the bolts properly, and check that if the blades can move on the shaft.
Never use worn, cracked or repaired shackle when the blades are reinstalled. Replace with new
ones. For repairs beyond those previously listed adjustments, please contact your local dealer.
WARNING!!
Never install different types of flails on the mower. When replacing flails, always check the
thightening of the screws. Make sure all screws are properly tightened.
