34. Before reinstalling the gear box cover, try
raising and lowering the conveyor table with
the crank handle. If the worm wheel and
worm gear teeth (see
Figure 51) are not
engaged, the crank handle will only raise the
table.
If this happens, loosen the crank handle
mounting bolts, and move the worm gear
around until the teeth mesh with the worm
wheel, then secure the crank handle.
