1.3 Safety instructions for particular operating phases
Before commencing work
Before commencing work, make yourself familiar with the working environment at the place of
use. The working environment includes: obstacles in the area of work and manoeuvre, the
firmness of the floor, necessary protection at the site relating to public thoroughfares and the
availability of help in the event of accidents.
Site the machine on an even, firm and stable base!
Check for correct mounting of the blade regularly.
Immediately remove damaged or badly worn blades, as they endanger the operator whilst
rotating.
The material to be cut must be held securely in place on the table to allow no unexpected
movement during cutting operation.
Always cut with the blade guard in position.
Only fit NORTON diamond blades with continuous rim to the machine! The use of other tools
can damage the machine!
Read the blades’ specifications carefully to choose the correct tool for your application.
Attention is drawn to the use of BS2092 safety goggles in conformity with specified Processes
No.8 of the Protection of Eyes Regulation 1974, Regulation 2(2) Part 1. Also use the other
safety equipment as mentioned in the symbols plus a dust mask when dry cutting is applied.
Electrical powered machine
Always turn off the TR 231 and separate it from the main source of electricity before any work on
the machine is done.
Make all electrical connections securely to eliminate contact of live wires with spray water or
dampness
When TR 231 is used with water, it is IMPERATIVE that you earth the machine properly. Let a
qualified electrician check in case of doubt.
Press the red button (0) on the switch to stop the machine in case of emergency.
In the event of the TR 231 breaking down or stopping for no apparent reason, switch off the
main electricity supply. Only a qualified electrician is allowed to investigate the trouble and
remedy the fault.

The vibration value is lower and does not exceed 2.5 m / s.
Values determined using the procedure described in the standard EN 12418.
The measurements are made with new machines. Actual values may vary with site conditions, in
terms of:
Materials worked
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 AND COMMISSIONING
The TR 231 is delivered fully equipped. It is ready for operation after assembly of the diamond blade
and after connection to the appropriate power supply.
3.1 Assembly of the legs
Lift up one side of the saw and unfold the legs without wheels. Lift up the other side of the saw and
unfold the legs with the wheels.
3.2 Cutting head
You have to detach the cutting head by unscrewing the knob securing the head on the rail of the
machine.
3.3 Tool assembly
Only NORTON blades with a diameter of 231 mm can be used with the TR 231.
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 assemble a new blade, follow these steps:
Loosen the three screws holding the outer cover of the blade guard using the crosshead
screwdriver supplied with TR 231, and remove it.
Loosen the hexagonal nut (left threaded) on the blade shaft using the 18 mm wrench supplied
with TR 231, which holds the removable outer flange.
Remove the outer flange.
Clean the flanges and blade shaft and inspect for wear.
Mount the blade on the shaft ensuring that direction of rotation is correct (check with the arrow
on the blade guard). Wrong direction of rotation blunts the blade quickly.
WARNING: The blade bore must correspond exactly to the blade shaft. Cracked or damaged
bore is dangerous for the operator and for the machine.
Put outer blade flange back in place.
Tighten hexagonal nut using 18 mm wrench.
Put the outer cover of the blade guard back in place and tighten the three holding screws with
the crosshead screwdriver.
WARNING: 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.

3.4 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.
3.5 Water cooling system
Fill the TR 231 with clean water up to 1cm under the top edge of the water tray. The pump will
switch on together with motor.
Ensure that water is delivered adequately to 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.
3.6 Starting the machine
Connect the machine to the electrical supply. You can start it by pressing the switch on I. To stop
the machine, press switch on 0. 0 is also the emergency switch.

4 TRANSPORT AND STORING
4.1 Securing for transport
Before transporting the machine, always remove the blade and empty the water pan. Secure the
cutting head on the rail by using the knob. Store the longitudinal cutting guide and the side
extension in the pan. Fold the legs.
WARNING: this machine is not suited to be lifted with a crane.
Lock cutting head
Tighten angular cutting guide
Store the longitudinal cutting guide and the side extension
oDismount the table (unlock on each side)

4.2 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 water tray, and clean it thoroughly.

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 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 TR 231.
5.2 Cutting
To use the TR 231 correctly, you must face it with one hand on the cutting head, and the other on
the material to be cut to maintain it against the material stops. Always keep your hands away from
the moving blade.
The long longitudinal cutting guide and the side extension can help you to achieve high accuracy
cuts, even with large materials.
Put in place longitudinal guide

5.3 Cutting with an angle
You can cut from 0º to 45º by tilting the head rail. For this purpose:
Loosen the two knobs maintaining the head rail to tilt the head to the desired angle.
Retighten the two knobs.
5.4 General advice for the cutting
Only materials with max. dimensions of 1200x800x20mm and max. weight of 15kg can be cut
with the TR 231.
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.
Make sure the water pan contains enough water.
