BELT TENSION
It is important to the check the belt tension especially
in the first hours of working. To check the tension, it is
necessary to exert upon each belt a pressure of nearly
Ib. 8/9 if the flexion is over 1/2" "A", proceed as
follows:
1)
Lift the machine so as to unload the
spring.
2)
Loosen the two M14 bolts of the pulley support "C".
3)
Stretch the belt by means of the relative M14 screw
after having loosened the lock-nut "B".
4)
Check that the tension is correct and then tighten
the M14 bolts.
When the belts are worn always replace them
in complete series (3 belts).
USE
To begin mowing work, after having placed the bar on the ground, the blades should be well oiled
and the relative parts greased, then insert the power take-off and accelerate gradually until
reaching a speed of 500-550 revs per min.
BLADE REPLACEMENT
Blade replacement in the mowers is greatly facilitated
by the new fixture system and is carried out as follows:
unscrew the three M8 screws "D" rotate the head
upwards (this remains attached to the connect rod kit),
and extract the blade from the exterior using the
relative hook. To re-assemble the blade make sure
that the alignment of the two pegs with the head is
perfect (clean if necessary), then tighten the three
screws. The toothed blade is extracted from the
interior by unscrewing the M12 bolt that locks the head
to the connect rod kit lever "E".
