To adjust the bed rollers:
1. Lower the table to give yourself at least 4" of
working room below the cutterhead.
2. Loosen the locking set screws (Figure 12)
above the roller adjusters (4 total).
3. Raise or lower the rollers by rotating the
adjusters to reach your desired height.
4. Verify both sides of the bed roller are at the
same height and lock them in position with
the locking set screws.
5. Double check the roller heights to make sure
they did not move when you locked them (if
they did, repeat the procedure).

The height of the bed rollers will vary, depend-
ing on the type of material you intend to plane,
but as a general rule keep the roller height within
0.002"–0.020" above the table. When planing
rough stock, set the rollers high to keep the lum-
ber from dragging along the bed. When planing
milled lumber, set the rollers low to help minimize
snipe.

To ensure accurate results and make the adjust-
ment process quicker and easier, we recommend
using a Rotacator (see
Page 20) to gauge the
bed roller height from the table. If a Rotacator is
not available, a straightedge and feeler gauges
can be used, but care must be taken to achieve
satisfactory results.
Note: Misaligned bed rollers can be the root of
many planing problems, such as:
• Workpiece chatter and/or noisy operation
• Washboard surfaces
• Workpiece rotating during planing
• Tapered cuts
• Binding, causing the workpiece to jam
