Do not use the machine if the protection and/or safety devices are not efficient.
Before any maintenance intervention, set the main switch to zero and warn about the
machine stop by a sign.
5.1.1 Safety measures
Periodically press the emergency push button to make sure it is efficient.
Check if the motor brake stops the shaft for a max. time of 10 s; otherwise, to adjust
it, refer to § 5.3.
5.1.2 Tool maintenance
a) Keep the tools always cleaned to get the best working conditions.
b) Resin deposits mixed with wooden dust and small chips must be removed by a
hard bristle brush dipped in a suitable and safe thinner.
c) Do not use any other product, nor synthetic thinners of any kind.
d) By a jet of compressed air, remove every dirt residue and dry every part.
e) Clean the working table with a dry cloth.
Use gloves when handling the tools.
5.2 ELECTRIC SYSTEM MAINTENANCE
The maintenance of the electric parts must be performed by skilled personnel, with the
machine stopped, under authorization of the person in charge with the safety.
Before any intervention, it is indispensable to cut the machine electric supply out rotat-
ing the lockable main switch on “0”, than disconnect it electrically from the mains.
It’s not possible to perform any preventive intervention on the electrical system, but you
can only intervene when an element is damaged providing for its replacement; how-
ever it is possible to improve the reliability of the electrical parts following some provi-
sions:
•
all the motors are supplied with overload cutout, calibrated on the motor rated
current; avoid starting and stopping several times consecutively, as this
causes a motor overheating and make the overload cutout ineffective;
•
do not remove material required a power higher than the installed one;
•
replace the faulty components with others having the same features;
•
calibrate the overload cutouts at the rated current indicated on the motor plate.
