3 Assembly and commissioning

The machine is delivered fully equipped. It is ready for operation after assembly the diamond blade,
the blade guard and the guide-a-cut, and after connection to the appropriate power supply.

3.1 Tool assembly

Only NORTON CLIPPER continuous rim blades with a maximum diameter of 250 mm can be used
with the TT250G.
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 two screws (1) on the side of the machine and remove the water tank.
•
Loosen the hexagonal nut (3) on the blade shaft with the 19mm wrench (Caution: left threaded),
which holds the removable outer flange.
•
Remove the outer flange.
•
Clean the flanges and blade shaft and inspect for wear.
•
Mount the blade on shaft 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.
•
Reassemble the water tank in the frame, and retighten the two screws (1).
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.
