DIRECTION OF
FEED - EXTERNAL CUTS (FIG. 17)
The cutter bit rotates clockwise. (When
installed on a router table, the rotation is
counterclockwise.) Feeding the bit from left
to right will cause the bit to pull the router
towards the workpiece (FIG. 17). If the router
is fed in the opposite direction (right to left),
the rotating force of the cutter bit will tend to
throw the bit away from the workpiece.
This is called “Climb-Cutting”. “Climb-
Cutting” may cause loss of control, possibly
resulting in personal injury. When “Climb-
Cutting” is required (e.g. backing around
a corner), exercise extreme caution to
maintain control of the router. The high
speed of the cutter bit during a proper
feeding operation (left to right), results in
very little kickback under normal conditions.
However, if the cutter bit strikes a knot,
an area of hard grain, or a foreign object,
“Kickback” may result. Kickback may
damage your workpiece and could cause
you to lose control of the router, possibly
causing personal injury. Kickback is always
in the opposite direction of the clockwise
cutter bit rotation, or counterclockwise. To
guard against and help prevent Kickback,
plan your set-up and direction of feed so
that you’re always keeping the sharp edges
of the cutter bit biting straight into uncut
wood. Always inspect your workpiece for
knots, hard grain, and foreign objects.
WARNING:
Kickback causes the
power tool to jerk back toward the user,
causing possible loss of control and
serious injury. Always take precautions
against kickback as described in the
operator’s manual.
KICKBACK
Because of the high speed of the cutting
bit during a proper feeding operation (left
to right), there is very little kickback under
normal conditions. However, if the cutting
bit strikes a knot, an area of hard grain in
the workpiece, or a foreign object, the
normal cutting action could be affected
and cause “Kickback.” This Kickback may
cause damage to your workpiece, and could
cause you to lose control of the router,
possibly causing serious personal injury.
Kickback is always counterclockwise: the
opposite direction of the clockwise cutting
bit rotation.
To guard against and help prevent kickback,
always inspect the workpiece for knots,
hard grain, and foreign objects that could
cause a kickback problem and plan the set-
up and direction of feed so that the router is
always moving, and keep the sharp edges
of the cutting bit continuously biting straight
into new (uncut) wood (workpiece).
DIRECTION OF FEED – INTERNAL
CUTS (FIG. 18-19)
When making an internal cut, such as a
groove, dado, or slot, always try to have the
guide you are using with the router (edge
guide, straight edge, board guide), on the
right-hand side of the router as you make
the cut (FIG. 18).

GUIDE
When the guide is positioned on the
right-hand side of the router, the router
travel should be from left to right and
counterclockwise around curves (FIG. 18).
This counterclockwise action around the
curve could cause “Climb cutting”. Always
be alert and exercise extreme caution to
maintain control of the router when making
this type of cut around curves.
When the guide is positioned as shown in
FIG. 19, the router travel should be from left
to right and clockwise around curves.
