5.2.1 Mounting the crushing plates
The fixed crushing plate (18) has plane parallel surfaces, the movable crushing
plate (22) is convex on the crushing surface and it is a bit longer.
To replace the fixed crushing plate (18), remove the guide bolt (3) and take out the
crusher jaw (15).
After loosening the clamping block (16) the crushing plate (18) can be removed, the
replacement crushing plate can be inserted and the clamping block (16) must be
very firmly re-screwed.
To replace the movable crushing plate (22), pull the collecting vessel (12) out of its
mount. The screws of the clamping block (24) are now accessible without removing
the movable crusher jaw (21). Loosen the clamping block (24) and lift out the
crushing plate (22). Insert the new plate (or the old turned one) from below and
fasten it to the clamping block (24), which must then be screwed in tightly.
CAUTION Crushing jaw (15) hold on tight!
