Wear Machine
Lack of maintenance
Inappropriate tool for application
Tool in poor condition
Unskilled operator
Etc…
The exposure time to vibration is based on the performance of work (related to the adequacy
Machine / Tool / worked material / operator)
When evaluating risks due to hand-arm vibration, you need to take into account effective usage at
rated power of machine during a full day of work; quite often you will realise that effective utilisation
time represents around 50% of overall duration of work. You have to consider, of course, breaks,
water feeding, preparation of work, time to move the machine, disk mounting…

3 ASSEMBLY ANDCOMMISSIONING
The machine is delivered fully equipped. It is ready for operation when you mount the diamond
blade, the handles and the conveyor cart and after you connect to the appropriate power supply.
3.1Tool assembly
Only NORTON blades should be used.
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:
Loosen the screw in front of the blade guard and disconnect the water hose on its the left side
and open it.
Loosen the hexagonal nut on the blade shaft (attention: left threaded), which holds the
removable outer flange, with the supplied wrench.
Remove the outer flange.
Clean the flanges and blade shaft and inspect for wear.
Mount the blade on arbour ensuring that direction of rotation is correct. Wrong direction of
rotation blunts the blade quickly.
Replace outer blade flange.
Tighten the hexagonal (attention: left threaded), nut with the supplied wrench.
Close the blade guard, retighten the screw on the front of the blade guard and reconnect the
water hose.
ATTENTION: 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.
3.2Feet mounting
Use the provided screws to mount the feet on the frame.
3.3Electrical 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.
3.4Starting the machine
Press the green button to start the machine. Press the red one to stop it. The red button is also an
emergency stop button.

VERS.2016.01.12 CST 100/120/150_MAN_EN

3.5Water cooling system
Fill the water pan with clean water to approximately 1cm 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.

5 OPERATING THE MACHINE
In this part, you will find some safety tips to use the machine.
5.1Site of work
5.1.1 Sitting 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 around the machine for usage and maintenance of the CST.
5.2Cutting material
To use the CST correctly, you must face it with one hand on one of the 3 handles of the cutting
head, and the other ready to shut the machine down in case of emergency. Always keep your hands
away from the moving blade.
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 thanks to the hand wheel to the desired cutting depth. In “through
cutting”, lower cutting head until blade periphery reaches max. 3mm under the surface of the
conveyor cart (for maximal cutting depth).
Put the material on the table and maintain it firmly against the butting. (or the cutting guide when
appropriate).
Pull the cutting head slowly and without undue pressure towards the material.
You can tilt the head for bevel cuts. For this purpose, untighten the two black buttons on each
side of the frame, and tilt the head to the desired position (from 0 to 45º). Tighten then the two
buttons.
To cut thicker materials, you can cut a first side, and then reverse it to cut the total depth. You
can cut materials until 220mm depth. (370mm for the 500mm blade versions).
