W1747 20" Planer
SERVICE
To adjust the height of the infeed and outfeed rollers,
chip breaker and pressure bar using wood blocks and a
feeler gauge, do these steps:
1. Build the wood blocks by cutting a straight 6' long
2x4 in half.
Note: Having the wood blocks at an even height is
critical to the accuracy of your overall adjustments.
For best results, remove board warpage by squaring
the 2x4 with a jointer and table saw before cutting
in half.
2. DISCONNECT THE PLANER FROM THE POWER SOURCE!
3. Lower the bed rollers below the table.
4. Place one wood block along the left side of the
table, and place the other wood block along the
right side of the table, as illustrated in Figure 30.
5. Remove the dust port, top cover, and belt cover.
6. Adjust the table and use the feeler gauge until you
have a 0.040" gap between the edge of a knife at
bottom dead center (find by rocking cutterhead pul-
ley) and the wood blocks.
7. Lock the table height in place, as the wood blocks
will now be your reference points for the rest of the
adjustments.
8. Loosen the infeed roller adjustment jam nuts (Figure
32) and turn the adjustment set screws on each end
to raise the feed roller above the wood block (if nec-
essary), then bring it back down so it just touches
the wood block on both sides.
9. Lock the infeed roller adjustment set screws in place
with the jam nuts, making sure they do not move
while tightening.
10. Without moving the table, adjust the chip breaker
(Figure 29), pressure bar (Figure 28), and outfeed
roller (Figure 27) in the same manner, using the
wood blocks as your reference point.
11. When you are finished with the adjustments, replace
the top cover, dust port, and belt cover.
