CHECKING THE CLEARANCE BETWEEN THE TOOTH AND THE
UPPER BLADE GUIDE
Before activating the mower, one must periodically check that the
blade holder rod (M, Fig. 38) and the upper blade guides (N) are
coupled properly.
After many hours of work, wear of the blade guide material may
be seen, and this will cause an increase in the coupling tolerance
with the tooth blade.
An excessive coupling tolerance between the parts results in
material entering between the same, causing likely breakage of
the cutting blades or parts of them, also compromising the quality
of the cut.
In contrast, a reduced coupling tolerance generates a strong sliding
friction of the blade with consequent breakage of the blade holder
rod, the blade head or other elements of the hinge (connecting-
rod assembly).
Therefore it is important to restore the coupling properly!
The check must be carried out on all blade guides (Fig. 40) using
a 1 mm thick shim plate, supplied.
Always use personal protective equipment.
The tolerance allowed for optimal coupling is determined by
the insertion of a single plate (O, Fig. 41).
If a plate does not ¿ t between the teeth blade and the blade guide
one must add a shim (Fig. 38-39);
If instead two coupled plates can be inserted (P, Fig. 41) one must
remove a shim to restore the optimal coupling tolerance conditions.
CAUTION: when fi tting the blade guide it is important to leave
a coupling tolerance of about 1 mm with the sections holder
rod (L, Fig. 38).
Only with some models, before disassembling the blade guides (N,
Fig. 38), one must previously remove the ¿ nger blade tie rod (Q)
in Figure 42. Use a punch to facilitate the operation (R, Fig. 42).
Subsequently, only after having made sure that the blade guides
have been blocked, one must tighten the ¿ nger blade again via the
nuts, located at both ends, keeping to the 15 mm shown in Figure
42. Use a punch to facilitate the operation (R, Fig. 42).
This measurement allows to maintain the cutting bar in traction,
without bending it downwards
IMPORTANT: when replacing the teeth or the tooth-holding
bar, carry out the check described above. When required, put
back the shims to avoid striation or damage.
