3 ASSEMBLY AND COMMISSIONING
The machine is delivered fully equipped and assembled (although without diamond blade) and is
ready for operation after connection to the appropriate power supply.
3.1 Tool assembly
Only NORTON blades with a maximum diameter of 700 mm can be used with the CM70 ALU.
All tools used must be selected with regard to their maximum permitted cutting speed for the
machine’s maximum permitted rotation speed.
Before mounting a new blade into the machine, switch off the machine and isolate it from the main
source of electricity.
To mount a new blade, follow these steps:
1. Use the cardboard accessory to support the head while you fix it in place
2. Depending on the size of blade you will use, fix the head in one position or another.
3. Install the spring.
4. Unfold the legs and fix them in place

VERS. 2018.05 CM70 ALU_MAN_EN

3.2 Electrical connections
Electrical connections
The electrical equipment of the CM70 ALU cutting tables manufactured by Norton Clipper has an
IP54 protection degree. The power supply on this machine has an under-voltage coil to prevent the
machine from starting up unexpectedly. When there is a power cut or voltage drop that causes the
machine to stop, and once the normal power conditions have been re-established, the motor does
not start until the green button is pressed.
Check that,
the voltage/phase supply corresponds to the information indicated on the motor plate.
Available power supply must have ground connection in conformity with safety regulations.
The connecting cables should have at least a 2.5mm2-section per phase.
Switch on the machine
230V Motor
To start the machine, press the green button. To switch it off, press the red button.
Direction of rotation
The direction of rotation is indicated on the blade guard. If the direction of rotation does not
correspond to the direction shown by the arrow, then reverse the motor polarity by turning the phase
inverter inside the male plug with a screwdriver.
Emergency Stop
To restart the machine after an emergency stop, press green button. To stop the machine, press the
red button.
3.3 Water cooling system
Material saws are designed to work with water-cooled diamond blades. This is why one of the
essential components of its structure is the water tank that acts as a closed circuit cooling tank
(water is pumped up to the blade).
Put enough water in the tank (up to about 2.5 cm from the top edge), making sure the pump
body is fully submerged.
The blade should be sufficiently watered on both sides. You can adjust the amount of water
using the tap in the blade housing.
If the blade is not sufficiently watered, the segments may heat up, which accelerates damage
and increases the risk of blade rupture. This is why the pipes and nozzles must not be clogged.

VERS. 2018.05 CM70 ALU_MAN_EN
16
In no case should the water pump run empty. Therefore, ensure that the water level in the tank
never falls below the water suction of the pump.
If there is a risk of frost, please empty the blade cooling system completely.
During cutting operations, many impurities accumulate in the bottom of the tank. It is then
necessary to frequently change the water in order to guarantee the proper functioning of the
pump and optimal cooling of the blade. The tank is equipped with a drain plug which facilitates
this task.
4 TRANSPORT AND STORING
Take the following measures in order to transport the CM70 ALU securely.
4.1 Securing for transport
Before transporting or lifting the machine, always remove the blade and empty the water pan.
The conveyor cart must be secured:
move the conveyor cart to the end of the machine
fix it using the pin on the rear post of the chassis and the eye screw on the conveyor cart.
4.2 Transport procedure
The machine can be moved on a flat surface using its wheels. Only use the lift brackets to lift the
machine, as other parts of the machine are not designed for this purpose. The machine is not
intended to be transported by crane.
4.3 Long period of inactivity
If the machine is not going to be used for a long period, please take the following measures:
Completely clean the machine
Empty the water system
Take the water pump out of the slurry and clean it thoroughly.
The storage site must be clean, dry and at a constant temperature.

5 OPERATING THE MACHINE
5.1 Site of work
5.1.1 Siting the machine
Remove from the site anything, which might hinder the working procedure!
Make sure the site is sufficiently well lit!
Observe manufacturer's conditions for connecting to power supplies!
Place electric cables in such a way that damage by the device is excluded!
Make sure you have a continual adequate view of the working area so you can intervene in the
working process at any time!
Keep other staff out of the area, so you can work securely.
5.1.2 Space required for operation and maintenance
Leave 2 m in front of the machine and 1,5 m around it for usage and maintenance of the CM70
ALU.
5.2 Cutting methods
To use the machine correctly, you must face it with one hand on the handle of the cutting head, and
the other on the handle of the conveyor cart. Always keep your hands away from the moving blade.
5.2.1 Jam or fixed cutting
In jam or fixed cutting, the cutting head is locked in a fixed position and the material is pushed into it
as shown.
Lower the cutting head to the desired cutting depth (in “through cutting”, lower cutting head until
blade periphery reaches max. 3-5mm under the surface of the conveyor cart) by means of the
handle on the blade guard
Fix position by tightening the clamping device
Put material on conveyor cart
Push the conveyor cart slowly and without undue pressure towards the rotating blade and cut
the material.
NOTE: While recommended, it is not absolutely necessary to lock the cutting head into a given
depth position when jam cutting. The desired cutting depth can be maintained by holding firmly the
depth feed handle on the blade guard.
If the full depth of cut requires excessive pressure (on very dense material e.g.) make 2 or 3 shallow
cuts.

VERS. 2018.05 CM70 ALU_MAN_EN
18
5.2.2 Multiple step cutting
Multiple step cutting consists of moving the conveyor cart with the material to be cut back and
forward under the rotating blade,
Place the material to be cut on the conveyor cart firmly against the guide-a-cut and the
backstop, keeping the hands well away from the blade.
Move conveyor cart forward near the blade and pull down the cutting head until blade is lowered
to a point where it will lightly contact the surface of the material.
Then pass the material beneath with rapid full length strokes, taking a shallow cut
(approximately 3 mm deep) on the forward. On the backward stroke, lift the blade just clear over
the cutting line.
Complete each rapid stroke backward and forward by passing the material beyond the centre of
the blade before starting the reverse movement of the conveyor cart.
NOTE: the harder the material, the more rapid should be the forward and backward strokes.
Step cutting lessens the area of the blade circumference in contact with the material, keeping the
blade cool, running free and cutting at peak efficiency.
5.2.3 General advice for the cutting
Material weighing under 30 kg and having dimensions smaller than 600x500x265mm can be cut
with the CM70 ALU.
Before commencing work make sure tools are firmly seated!
Select the right tools as recommended by the manufacturer depending on the material to be
worked, the working procedure (wet cut) to be carried out and the required efficiency.
Apply cooling water continuously whilst cutting and in good time!
When cutting work is finished, close the water-tap so you can remove the cut pieces from the
conveyor cart without getting wet.
If the thermal protection trips, wait a few minutes to allow the motor to cool down before
restarting the machine.
In case of the triggering of the thermal protection, press the black button on the switch (230V
motor) .
