SCREENS REPLACEMENT
The screens are changed when they have worn so
much that they are about to break or when you are
going to grind a different material to the one that is
specified for the screen that is set.
The steps to change the screens are the following:
1. Turn the feed hopper (A).
To perform this operation, pull and turn any of the
security bolts.
Repeat the operation with the second security bolt.
Stand on the opposite side and remove the lock.
Slowly press the feed hopper from the point of entry
of this until it rests on the tire.
2. Verify that the screen is not bent or blocked with
some of the flanges, guides or hammers.
3. Pull the screen from its fold (B). If the screen does
not come out, with the help of a piece of wood, push
it slowly from the opposite side and pull it again until
it comes out.
4. Place the screen that you want to use, being careful
to slide it only between the guides (C) and the flange
(D), not over them as it can get stuck, resulting very
difficult to remove it since the hammers will hold it.
5. Push the crib until it hits the stop (E).
ATTENTION: When placing the screens
you must be careful with your hands (wear
gloves). Once the screen is supported on the
flanges, push it gently so that when it reaches
to the stops, you can remove your fingers to
avoid an accident.
