DRUM BLOCKAGE -- Figures 38 and 39
Should the drum become blocked, proceed as fol-
lows:
1. Lower the concave to its lowest position and try to
unblock by engaging the threshing mechanism at
low engine speed.
2. If this is ineffective, try to unblock the drum by us-
ing the drum socket wrench A (i.e. when the stan-
dard drum variator is fitted).
The drum socket wrench A is located under the
fuel tank and is secured with latch B.
