W1747 20" Planer
SERVICE
To adjust the table parallelism, do these steps:
1. DISCONNECT THE PLANER FROM THE POWER SOURCE!
2. Remove the motor access panel and locate the chain
on the underside of the table.
3. Loosen the lock bolts and idler sprocket (see Chain
Tension instructions on Page 28).
4. Mark the location of one tooth in the sprocket that
you are adjusting.
5. Move the chain away from only the sprocket you
want to adjust so only that sprocket can be turned
independent of the chain.
Note: If the left side of the table is too high, the
left two sprockets will need to be adjusted. 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.
6. Carefully turn the sprocket (clockwise to raise the
table; counterclockwise to lower the table) just
enough to position the next tooth at the marked
location, then fit the chain around sprocket again.
7. Repeat Steps 4–6 with each sprocket that needs to
be adjusted until the table-to-cutterhead clearance
is within 0.016" from one side to the other.
8. Make sure the chain is properly fitted on the sprock-
ets, and tighten the idler sprocket and lock bolts.
9. Micro-adjust the table position by loosening the cap
screws (Figure 24) using a 6mm wrench, and lifting
the table upward or downward until the table and
cutterhead are in alignment.
Note: This process may require adjusting the col-
umns on both the left and right hand sides until you
find the correct combination.
10. Replace the motor access panel.
