Adjusting the Subfences
The (2) MDF (medium density fiberboard) subfences are
designed to slide along the fence approximately 2".
This results in a router bit opening from 0 to 4".
A. "Close" Setting
Many applications require adjusting the subfences close
to the router bit. This accomplishes nearly the same
benefits of a true "zero clearance" setting (see "B")
without cutting the subfences. Before the router is
turned on, and after the fence and router bit height are
properly adjusted, slide the subfences toward the bit to
reduce the gap. Confirm that the router bit can freely
rotate without touching the subfences!
B. "Zero Clearance" Setting
Cutting the subfences into the router bit profile produces
"zero clearance". Zero clearance eliminates the gap
between the fence and router bit. This prevents the
workpiece from getting pulled into the fence just before
the router bit. Moreover, a zero clearance setting
achieves a cleaner cut because the subfence supports
the workpiece fibers. If a true zero clearance setting is
desired, follow these steps:
1. Adjust the bit height and fence position. Note: the
subfences must NOT contact the router bit at this time.
2. Install the bit guard and secure.
4. Start router, and use dust collection. From the back of
the fence, slightly loosen the subfence knobs and
carefully slide the infeed subfence into the spinning
router bit. Hold onto the subfence knobs.
5. After the subfence has reached the guide bearing of
the router bit, fully tighten the knobs on the subfence.
Note: If the bit does not have a guide bearing (i.e.
vertical raised panel bits), slide the subfence half-way
into the bit, then tighten the subfence knobs.

The infeed subfence is wide open, and the
outfeed subfence is set to "close".

adjusted to zero clearance.

Important Notes:
The outfeed subfence is rarely set to zero clearance,
because doing so has little performance benefit and can
damage the subfence. A "close" setting is more desirable for
most applications. Setting the outfeed subfence to zero
requires great care because the router bit can cause a
portion of the subfence to chip or break. If an outfeed zero
clearance is absolutely necessary, slide the outfeed
subfence very slowly into the bit to minimize the chipping
and tearing.
The subfences can be flipped when changing profiles or bit
heights. New, replacement subfences are available when a
new profile is to be created or if the subfence cannot be
trimmed to provide a fresh edge.
MDF works very well as a subfence because it is softer than
most woods and is much less likely to damage expensive
router bits. MDF also retains the shape of delicate profiles
and thus allows proper support for zero clearance settings.
When adjusting the fence, ensure that no part of the
aluminum fence body could contact the router bit.
Caution: Never adjust or slide the
subfences from the front! Always work
from the back with both hands on the
adjustment knobs.
