Model G1033/X/Z (Mfd. Since 02/19)

To adjust table parallelism:
1. DISCONNECT MACHINE FROM POWER!
2. Remove motor access panel and locate
chain on underside of table.
3. Loosen lock bolts and idler sprocket (see
Tensioning Table Height Chain instructions
on
Page 45).
4. Move chain away from sprocket you want to
adjust so only that sprocket can be rotated
independent of chain.
Note: If the left side of the table is too high,
the left two sprockets will need to be adjust-
ed. Each tooth on the sprocket represents
0.016" of vertical movement as the cogs are
turned. Make sure, as you turn the sprockets,
to keep an accurate tooth count to ensure
that the table is adjusted equally.
5. Mark location of one tooth of sprocket that
you are adjusting.
NOTICE
When making adjustments, tighten fasten-
ers after each step to ensure the accuracy
of your tests. When adjusting the chain
sprockets, keep in mind that if the chain
becomes too loose, it will fall off of all the
sprockets, and returning it to its proper
location can be extremely difficult.
6. Carefully rotate sprocket (clockwise to lower
table; counterclockwise to raise table) just
enough to position next tooth at marked loca-
tion, then fit chain around sprocket again.
7. Repeat Steps 4–6 with each sprocket that
needs to be adjusted until table-to-cutterhead
clearance is within 0.016" from one side to
the other.
8. Make sure chain is properly fitted on sprock-
ets, then re-tighten idler sprocket and lock
bolts.
9. If necessary, micro-adjust table position by
loosening cap screws shown in
Figure 66
and raising or lowering table until it is properly
aligned with cutterhead.
Note: This process may require adjusting the
columns on both the left and right hand sides
until you find the correct combination.
