8.  USE WARNINGS

We recommend following the indications below in order to always work in safety conditions.

All the operations must be carried out complying strictly with the safety rules of the country

where the device is to be installed.

It is STRICTLY FORBIDDEN to smoke during the installation or adjustment operations of the

cutting unit.

The Customer undertakes to comply with and make his staff observe all the rules and

regulations in force concerning safety, prevention of accidents and health in the work

place. Therefore, the Customer assumes the responsibility to strictly follow all the rules and

regulations in force, as well as the special provisions in force in sport and public installations

the Customer declares to know after receiving all the relative necessary information.

The cutting unit works also without its safety protective device. This protective

device must NEVER be removed.

Always check the resistance of the material to be cut and the kind of blade which is being used.

The Customer shall equip his own personnel with all the individual safety protections for

the execution of the works, as well as with the ones which might be prescribed by the

Manufacturer due to specific danger conditions of the plant or of the area where the

personnel must work.

Do not make any adjustment while the blade is working or while the electric plug is

connected.

Always pay attention to the electric cable position to prevent it from being cut or damaged

by the blade.

It is allowed to assemble cutting unit GRT12SM on machines O.E.M. on condition that their

original structure is not modified. Otherwise, the intervention must be certified by Rasor

®

.

Firstly make sure that the lines are able to supply the cutting unit with power correctly,
in compliance with the safety rules (for the feature required see par. 5).

We suggest installing a magnetothermic safety device before the cutting unit and check that

the ground circuit is effective. Before working on the feeding cable pull the plug out. Check

that electric connections and protections correspond to the driving force and the plate data
values (voltage and current), required by the different electric circuits. By referring to the

CEI 11-27/1 standard all the works carried out by means of electric current must be performed

by  staff provided with all the devices required by the above-mentioned standard. For the
works carried out under voltage, it is necessary that the employer certifies the staff suitability,

after a training period. The cutting unit GRT12SM is supplied

with electric cable connected to the connector block located

near the motor. The user must connect the cutting unit to the
mains (the cable complies with the CEI 20-22 III Standard).

Never change the length of the supplied cable. If necessary, use

a longer cable and replace the one supplied. To connect the
new cable open cover “

A

” by unscrewing the 4 cross-slotted

screws “

B

” (see picture 3). Connect the phase cable to the

terminal board. The minimum section of the connecting cables

must be determined by the operator in charge of the installation.

We recommend using  IMQ approved safety cables and sockets.
Check the connection by enabling the cutting unit and verify

the rotation direction. The cutting unit is provided with earthing

(yellow-green cable).
