Setting Feed Rate

High Feed Rate .......................................20 FPM
The infeed and outfeed rollers move the work-
piece through the planer while keeping it flat and
providing a consistent rate of movement. The
speed that these rollers move the workpiece
through the planer is the feed rate.
Generally, low feed rates are used for finishing
passes, while higher feed rates are used for
dimensioning passes.
The figure below illustrates the three different
positions of the feed rate control knob:
• Push knob in to use high feed rate.
• Pull the knob out to use the low feed rate.
• Move knob to center position to place gear-
box in neutral.
Figure 21. Feed rate control knob positions.
NOTICE
Only change the feed rate when the planer
is running, but DO NOT attempt to change
the feed rate during any cutting operations
or damage to the gearbox will result.

Bed Roller Height

Bed Roller Height Range ..............0.002"–0.020"
The correct height of the bed rollers will vary,
depending on the type of material you intend to
plane. However, as a general rule, keep the bed
roller height within 0.002"–0.020" above the table
surface, as illustrated in Figure 22.

Figure 22. Recommended bed roller height
above the table surface.
When planing rough stock, set the rollers high
to keep the lumber 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 (refer to Accessories on Page
31) to gauge the bed roller height from the table
surface. If a Rotacator is not available, a straight-
edge and feeler gauges can be used, but care
must be taken to achieve accurate results.
NOTICE
Bed rollers that are not adjusted to the cor-
rect height or out of alignment with each
other can cause poor finishes, inconsistent
planing thickness, and other undesirable
results.
