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 can be used with the CM501.
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:
•Open the shaft vent cover on the blade guard.
•Loosen the hexagonal nut on the blade shaft, which holds the removable outer flange.
•Remove the outer flange.
•Clean the flanges and blade shaft and inspect for wear.
•Mount the blade on arbor ensuring that direction of rotation is correct. Wrong direction of rotation
blunts the blade quickly.
•Replace outer blade flange.
•Tighten hexagonal nut with spanner supplied for this purpose.
•Shut the vent cover.
The blade bore must correspond exactly to the diameter of the blade shaft. Cracked or damaged
bore is dangerous for the operator and for the machine.
3.2 Electrical connections
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.
3.3 Starting the machine
230V Motor
Open the switch cover and press the green button to start the machine. To stop either use the red
button or press directly on the switch front cover.
115V Motor

0.

VERS. 2017.06.21 CM 501 ME_MAN_EN
18
400V Motor
Put the ON-OFF-Switch on ON. Then put the Star-Triangle-Switch on Y. Wait until the blade
reaches its maximum rotational speed, then turn the Star-Triangle-switch on ∆.
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.
Machine dual voltage 230V/400V
Set the 230V/400V switch on the voltage corresponding to the one supplied to your machine. A
wrong voltage choice can damage the electrical equipment of your machine.
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.
3.4 Water cooling system
Fill the water pan with clean water to approximately 2cm from top (ensure that bottom of pump is
fully immersed in water).
Open water-tap at blade guard (note that handle on water-tap should be in line with water-flow).
Ensure that water is flowing freely in the circuit and is delivered adequately to both sides of the
blade, as insufficient water supply may result in premature failure of the diamond blade.
The water pump must never run without water. Always make sure that there is enough water in the
pan and refill if necessary.
In case of frost, empty the water cooling system from its water.
4 TRANSPORT AND STORING
4.1 Securing for transport
•Before transporting or lifting the machine, always remove the blade and the conveyor cart and
empty the water pan.
4.2 Transport procedure
If you transport the machine using a fork-lift truck, you have to use EXCLUSIVELY the two fork lift
brackets under the water pan.
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
•Loosen the drive belts
•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 CM501.
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 conveyor cart. You can possibly press on the pedal with one foot. Always keep your
hands away from the moving blade.
5.2.1 Full depth or fixed cutting
In full depth 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. 3mm under the surface of the conveyor cart) by means of the
handle on the blade guard or of the foot pedal, or using the crank.
•Put material on conveyor cart against the backstop.
•Push the conveyor cart slowly and without undue pressure towards the rotating blade and cut
the material as shown on the picture.
NOTE: While recommended, it is not absolutely necessary to lock the cutting head into a given
depth position with the crank when jam cutting. The desired cutting depth can be maintained by
holding firmly the depth feed handle on the blade guard or pressing on the foot pedal. If the full
depth of cut requires excessive pressure (on very dense material e.g.) make 2 or 3 shallow cuts.

VERS. 2017.06.21 CM 501 ME_MAN_EN
20
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 as shown on the picture) 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 weighting under 40 kg and having dimensions smaller than 600x500x390mm (cut with
reversing of the material) can be cut with the machine.
•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 (dry or wet cut) to be carried out and the required efficiency.
•Apply cooling water continuously whilst cutting and in good time! Make sure the water pan
contains enough water.
•When dry cutting, ensure sufficient dust extraction and wear a dusk protection mask! You can
also order a dust extraction device (Art. Number 00310004580).
•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, reactivate the motor by pushing on the black button located on the
motor (230V motors) or on the switch (115V motors) or allow the thermal protection to cool down
(400V and dual tension 230V/400V motors). Wait a few minutes to allow the motor to cool down
before restarting the machine.
