IMPORTANT
☞
•
If the filtering element is excessively clogged or damaged,
provide for changing it.
This check must be carried out according to time intervals fixed
by the operator, since any anomaly regarding the wheel toe-in is
due to impacts or vibrations that depend on the type of surface
on which the machine works.
Another reason that shoud lead the operator to perform this
check is the excessive wear of the front tyres.
The machine has been designed with a toe-in equal to 0 mm.
Every adjustment must restore this value and must be carried
out on the coupling bars (1) after loosening the nuts (2) that lock
them. (Use 27 and 19 mm spanners).
During this check and the relevant adjustment, it is advisable to
check also the conditions of the articulated heads (3); if a con-
siderable slack is observed, immediately provide for changing
them.
