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.

Electrical powered machine

• Always turn off the machine 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 the machine 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 on the switch to stop the machine in case of emergency.

• In the event of the machine 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.

3 Assembly and commissioning

The machine is delivered fully equipped. It is ready for operation after assembly the diamond blade
and after connection to the appropriate power supply.

3.1 Assembly of the legs

Lift up one side of the saw, slide in the legs (with no wheels) to the front side of the saw. Lock the
wing nut to tighten the legs in place. Lift up the other side of the saw and slide in the legs with the
wheels. Lock the wing nut to fasten the legs in place.

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 maximum diameter of 250 mm can be used with the TR 250.
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 on the two nuts holding the outer cover of the blade guard, and remove it.

• Loosen the hexagonal nut (left threaded) on the blade shaft with the 30mm wrench, 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 arbor ensuring that direction of rotation is correct (check with the arrow

on the blade guard). Wrong direction of rotation blunts the blade quickly.

• Replace outer blade flange.

• Tighten hexagonal nut.

• Retighten the two mutter screws maintaining the outer cover the blade shaft.

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.

10

3.5 Water cooling system

• Fill the water pan with clean water to 1cm of the edge of the water tray.

• Ensure that water 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.

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.

11

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.

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.

The storage site must be clean, dry and at a constant temperature.

12

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 TR 250.

5.2 Cutting methods

To use the machine correctly, you must face it with one hand on the cutting head, and one on the
material to be cut to maintain it against the material stops. 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 depth pushed into the material 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 table) by means of the handle on
the blade guard

• Fix position by tightening the clamping device

• Put material on table

• Push the cutting head slowly and without undue pressure towards the material 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 cutting head. If the full depth of cut requires excessive pressure (on very
dense material e.g.) make 2 or 3 shallow cuts.

13

5.2.2 Multiple step cutting

Multiple step cutting consists of moving the head back and forward on the material to be cut.

• Place the material to be cut on the table firmly against the guide-a-cut and the backstop,
keeping the hands well away from the blade.

• Move blade forward near the material 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 blade 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 cutting head.

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.

5.3 Cutting with an angle

You can cut from 0º to 45º by tilting the head. To this purpose:

• Loosen the two knobs maintaining the head to tilt the head to the desire angle.

• Retighten the two knobs.

5.4 General advice for the cutting

• Only materials with max. dimensions 1110x490x60mm and max. weight 10kg 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.

• Make sure the water pan contains enough water.

• Set the guide-a-cut to the desired width of cut, and to the desired angle using the two engraved

measurements to align it correctly.
