9.1
Fitting the belt arm
If the grinder is fitted with a grinding
screen this must be completely
removed before the belt arm is fitted.
When fitting the belt arm, first fit the
link (H). The belt arm can then be
fitted onto the link and you can
secure it with the bolt (I). Then you
can put the spacer (G) on the shaft,
followed by the contact wheel (F) and
finally the nut (E). Then put the
grinding belt (D) onto the belt arm,
and finally secure the outer shield (C)
to the wheel (B) and nut (A).
9.2
Replacing the grinding belt
When the grinding belt has worn down it must be replaced, which is done in the
following way: Remove the outer shield (A) (see
fig. 3.2
) of the casing and pull the
handle (B) down. This releases the grinding belt (C), so it can be removed and
replaced by a new one, which should be fitted in reverse order. Check that the
direction of the arrows on the rear of the belt corresponds to the direction of rotation.
Once the new grinding belt has been fitted, it is necessary to ensure a straight
running action by adjusting the handle (D), which should be loosened until the
grinding belt runs straight on the contact wheel. Then tighten the handle (B).
This adjustment of the grinding belt must only be carried out by pulling the
grinding belt manually, and never with the machine switched on.
