Troubles
14.1 Possible functioning troubles.
Causes and remedies
A correct operation of the machine depends mostly on a correct set-up and maintenance.
It is very important that the rotor speed (r.p.m.) is conforming to the prescribed settings, i.e.
between 1000 and 1500 r.p.m.
The chipped material appearance (sharp cutting profile and no defibration) lets you
understand whether the counter-blade is properly adjusted or the blade and counter-blade
are sharp.
A fibrous chopped material signals for a blunt cutting edge or an excessive distance between
blade and counter-blade; these situations cause an excessive stress of the engine and can
provoke clogging at outlet with consequent blockage of the machine.
