4.2 DESCRIPTION OF THE MACHINE AND ITS COMPONENTS
The NTS 370 circular cutting-off machine for ferrous metals produced by MACC is made from a solid casting , carefully
machined and provided with holes for fastening to the platform : the upper surface has been worked using precision
machinery to allow the attachment of a sturdy vice with burr-proof jaws .
The bar-stop device allows the length required to be present and a constant level of performance for repeated cuts .
The blade-holding head made from a cast-iron structure is a reduction unit in oil bath built onto the motor . The coolant
pump is installed on a tank which is situated inside the machine platform .
The main switch is located on the front panel . Another switch is used to select motor rotation speed and therefore
cutting speed . The blade is protected by a guard which in its turn protects the operator from ejected shavings and
coolant . The machine is supplied with a set of service spanners .
4.3 INTENDED AND UNSUITABLE USES OF THE MACHINE
The NTS 370 cutting-off machine ith circular blade has been designed and built to cut bars , structural steel
and ferrous metal pipes in accordance ith the instructions contained in this manual .
Therefore , the cutting of other materials is not permitted : if the above recommendations are not observed , the
machine could be damaged and the health and safety of the operator put at risk .
Cutting is not permitted , if the bar has not been first locked in the vice .

7. MACHINE INSTALLATION
A. MACHINE CHECK
The machine should be checked to make sure that it has not been damaged during transportation and handling . f the
machine appears to have been damaged, contact MACC immediately. Fit all the supplied accessories onto the machine
B. FASTENING OF THE MACHINE
The machine ill be able to operate in keeping ith the technical parameters supplied by MACC if it is
positioned correctly and fastened securely to the bench or the factory floor so that vibrations are minimal
during operation . Levelling : Open vice ja s manually to maximum extent . Place machine level on vice bed
and level machine using the levelling scre s provided .
C. ASSEMBLY OF CIRCULAR BLADE
1-Remove guard 61 exposing saw shaft and saw collars .
2-Remove bolt 97 and outside flange 57 .
3-Loosen screw on pinchip wheel bracket and slide pinchip wheel out of the way .
4-Mount the saw blade on the arbor with teeth of blade moving counter clockwise .
5-Move pinchip wheel into the saw blade , meshing the pins and teeth loosely . Rotate the blade by hand to ensure
proper mesh with pinchip wheel . The pins should not protrude through the saw blade more than 1/16” .
6-Replace outside flange 55 and bolt . Turn blade clockwise up against drive pins and securely tighten bolt .
7-Replace guard 61 .
( Points 3 and 5 should only be followed for machines with scrap-breaker ) .
D. ELECTRICAL CONNECTION TO THE MAINS
Install a differential thermomagnetic s itch ith characteristics suited to the mains .
Make sure that the power supply voltage corresponds to the voltage on the motor plate . Connect the cable to the power
supply line observing the colour codes of the individual wires , pay particular attention to the earth wire . Connect the
machine , make sure that the rotation of the circular blade is in the direction shown by the arrow on the guard .
E. CUTTING COOLANT
For the cooling of the circular blade , fill the tank with emulsible oil obtained from a mixture of water and WLADO L
EMULSOL SGA/NF oil with a percentage of 5-7%

8.3 OPERATION
CHECKS TO CARRY OUT BEFORE EACH CUT
A. Make sure that the circular blade is fastened securely by means of screw 97 ( Encl.5 )
B. Check that the hand indicates the required cutting angle .
C. Make sure that the piece to be cut is adequately secured in the vice .
D. Make sure that the coolant is circulating in the machine .
E. Adjust the head stops so that the idle stroke is not too long .
F. Position the clamp vice by operating on the screws , so that it is the nearest possible to the blade .
G. When starting the motor , make sure that the blade rotates in the direction of the arrow
CUTTING OPERATION
A. Before starting to cut , if the tilting of the cut is not satisfactory , adjust this by raising the working head to
maximum up position , loosening the fastening handle 94 and turning the rotating head to the required position and
then fastening with the same handle .
B. Position the vice at 4 mm from the part . Adjust the head stops so that the idle stroke is not too long . Set the lowering
of the head by making it perform an idle cycle . Place the part to be cut to the set size , rotate the motor head commut-
ator in the wanted position then press the START push-button .
To make a series of cuts , position the bar-stop 145 at the size required . Fix it into position by using the knob .
C. To replace the circular blade carry out the same operations used to assemble the circular blade . ( chapter 7c ) .
D. For the choice of most suitable blade consult the table Encl.1 .
E. Every time the machine is s itched on , hen it s itches off or if the emergency push-button has been
pressed , set the machine to the starting position and press the RESET button to start the cycle again
( in the third case , release the emergency button first ) .
We strongly discourage the use of blades ith ruined or insufficiently sharp cutting edges
8.4 SPECIAL SAFETY CHECKS
A. Before using the machine , check carefully that the safety devices are in good working order , that the mobile parts
are not blocked , that no parts are damaged and that all the components are installed correctly and are functioning
properly .
B. Make sure , before operating the machine , that the scre s of the guards and other protective devices are
adequately secured , especially the scre s on the circular blade guard .
C. Check that the safety micros itches and the emergency button are functioning correctly . Test them during a
loadless machine cycle .
D. Pay attention to environmental conditions . Do not expose the machine to rain ; to not use it in damp environments ,
position the machine on a clean dry floor that has no oil or grease stains .
E. Before using the machine , the operator should make sure that all tools and service spanners used for maintenance
or adjustment have been removed .
8.5 GENERAL SAFETY RULES
A. Wear appropriate clothing . The operator's clothing should not be loose or dangling nor should it have parts which
could easily get caught . Sleeves should contain elastic .
Belts , rings or chains should not be worn . Long hair should be kept in a net .
B. Avoid unstable operating positions . Find a safe and evenly balanced position to operate the machine .
C. Keep the work area tidy , untidiness increases the risk of accidents .
D. Do not use the power supply cable to disconnect the plug from the socket. Protect the cable from high temperatures ,
oil or sharp edges . For outdoor use , only use extension cables which are in line with current regulations .
8.6 MEASURES TO PREVENT RESIDUAL RISKS
A. The removal of guards and tampering with the safety devices is strictly forbidden .
B. Gloves safety glasses should always be worn .
C. Standard work clothing should be used and kept closed and should not have flapping parts .
D. The machine should not be cleaned with liquids under pressure .
E. n the event of fire , extinguishers should not be used unless they are the powder type . The electric power supply to
the machine should always be disconnected in these circumstances .
F. Do not insert foreign bodies into the motor cover and to not supply the machine with voltage by tampering with the
safety microswitches or main switch .
G. Take the necessary precautions to avoid the machine being started by other people during loading ,
adjustment , piece changing or cleaning .
