3.3 Tool assembly
Only NORTON blades with a diameter of 230 mm can be used with the TR 230.
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 230, and remove it.
•
Loosen the hexagonal nut (left threaded) on the blade shaft using the 18 mm wrench supplied
with TR 230, 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 2.5mm
2
-section per phase.
3.5 Water cooling system
•
Fill the TR 230 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.
