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
