C. Cleaning of coolant tank and the swarf collection tray .
Empty the swarf collection tray and the coolant tank and keep the waste materials for future disposal . Clean out the
shavings and the metallic powder , taking care not to scatter this over the machine especially around the motor and the
box containing the electrical equipment . Fill the tank with the amount and liquid stated previously ( 8 litres ) .
D. Adjustment of slides .
The slides of the head are tempered and ground . The adjustment has been made by the manufacturer but play may
form after some time . This space can be eliminated with a screw ( Encl.6 ) .
10. INFORMATION REGARDING ENVIRONMENTAL NOISE
An environmental noise test carried out on the NTS 370 cutting-off machine with circular blade , identical to the
machine to which these operation instructions refer , has given the following results :
ACOUSTIC RADIATION PRESSURE
1.
LAeq = 83.8 dB ( A )
2.
Lpeak = 92 dB ( the maximum acceptable value is 140 dB ) .
3.
The level of background noise has no influence = 48.5-54.2 dB ( A ) .
The considerable data are the result of tests made under the D. lgs. 277/1991 in the implementation of the directives nr.
80/1107/CEE , nr. 82/605/CEE , nr.84/477/CEE , and 88/642/CEE .
11. LAYING OFF AND DISMANTLING
11.1 LAYING OFF
If the machine is to be laid off or left idle for a long period , the following operations must be carried out :
1. Disconnect the machine from the electricity mains .
2. Empty oil from the gear box and cooling liquid from its tank
3. Clean carefully the machine by getting rid of all traces of grease , especially on the worked parts that must be
protected with anti-oxidants .
4. Cover the machine with a sheet , preferably not plastic as it can cause rust due to the humidity condensation .
5. Store the machine in a closed , dust-free place .
11.2 DISMANTLING
If the machine must be definitively dismantled , its components must be sub-divided for the purpose of a possible
recycle of the materials and for the environment safety . The following table is given for your guidance :
Steel

Used oil and materials must be disposed of according to 87/101/EEC Directives and to country specific regulations .
The disposal of electrical components is provided for by European Directives 2011/65/UE .
