3 ASSEMBLY AND COMMISSIONING
The machine is delivered fully equipped (although without diamond blade). It is ready for operation
assembly the diamond blade, the feet and the conveyor cart and after connection to the appropriate
power supply.
3.1 Tool assembly
Only NORTON blades with a maximum diameter of 350 mm can be used with the CM 350B.
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
battery.
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 Feet and conveyor cart assembly
Feet and conveyor cart are located in the water pan. Place the four feet in the four openings on
each corner of the frame. Tighten the four locking screws.
Place the conveyor cart on the guiding rails with the material stop facing the operator.

position) the 3 LEDs will lit.
•Wait until the green LED on the control panel is the only one lit
•Put the switch to ON to start the motor and the rotation of the blade (2)
NOTE: When removing the battery, remember to replace the plastic cover on the motor plug to keep
it clean.
NOTE: These operations must be done each time the motor is restarted (even if the engine has just
been stopped)
To stop the machine, put the switch on the control panel to OFF or press the emergency stop.

VERS. 2023.06.12 CM 350 B_MAN_EN
16
3.5 Charging the battery
This machine works with a battery, so you have to think
about charging it. A fast charger is available for this. It will
take between 1h and 1h30 to recharge a full battery charge.
When charging the battery, the charger fan turns on to
prevent the battery from heating up. The charger will stop
automatically once the battery is fully charged, but the fan
will remain on for a while to keep the battery cool.
NOTE: The battery must not be charged at a temperature
equal to or lower than 5°C.
3.6 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 the water-tap on 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 OPERATING THE MACHINE
4.1 Site of work
4.1.1 Siting the machine
•Remove from the site anything, which might hinder the working procedure!
•Make sure the site is sufficiently well lit!
•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.
4.1.2 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 CM 350B.
4.2 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. Always keep your hands away from the moving blade.
To start the machine, press the power button, when the green LED is the only one lit, put the switch
on the ON position. To stop the machine, put the switch on the OFF position or press the
emergency stop.
4.2.1 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
•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 as shown on the picture.
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. 2023.06.12 CM 350 B_MAN_EN
18
4.2.2 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.
4.2.3 General advice for the cutting
•Material weight under 15 kg and having dimensions smaller than 500x500x150mm 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!
•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 and wait until the motor has cooled down before starting the machine again.
