3.8 Installation of the material holding system
In order to ensure an optimal material holding during the cut, use the grasshoppers envisaged
for this purpose.
3.9 Tool assembly
Only NORTON blades with a diameter of 250 mm can be used with the TR 252.
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 252, and remove it.
Loosen the hexagonal nut (left threaded) on the blade shaft using the 18 mm wrench supplied
with TR 252, 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.
