Some workpieces are not safe to cut or may
require modification before routing. Before rout-
ing, inspect all workpieces for the following:
• Material Type: this router is intended for cut-
ting natural and man-made wood products,
laminate covered wood products, and some
plastics. this machine is not designed to
cut metal, glass, stone, tile, etc.
• foreign Objects: nails, staples, dirt, rocks
and other foreign objects are often embed-
ded in wood. While shaping, these objects
can become dislodged and hit the operator,
cause kickback, or break the bit, which might
then fly apart. always visually inspect your
workpiece for these items. if they can't be
removed, do not cut the workpiece.
• Large/Loose Knots: loose knots may
dislodge during a cutting operation. Knots
can cause kickback and machine damage.
Choose workpieces that do not have large/
loose knots or plan ahead to avoid shaping
through them.
• Wet or "Green" Stock: routing wood with a
moisture content over 20% causes unneces-
sary wear on the cutters, increases the risk of
kickback, and yields poor results.
• Excessive Warping: Workpieces with exces-
sive cupping, bowing, or twisting are danger-
ous to cut because they are unstable and
often unpredictable when being shaped. do
not process workpieces with these charac-
teristics unless you properly square up the
stock with a jointer and planer.
• Minor Warping: Workpieces with slight cup-
ping can be safely supported if the cupped
side is facing the table or the fence. a
workpiece supported on the bowed side will
rock during a cut and could cause kickback or
severe injury.
Workpiece
Inspection
Jointing the edge of a board involves using a
straight cutting router bit to remove wood from the
face of the board. the result is a perfectly flat and
square edge.
To joint the edge of a workpiece:
1. diSConnECt routEr FroM poWEr!
2. Secure a straight cutting bit into your rout-
er according to the router manufacturer's
instructions.
3. install the smallest table insert into the router
table that still allows the router bit to freely
rotate.
4. raise the bit to a height slightly more than
that of the workpiece, then rotate it by hand
until the cutting flute is perpendicular to the
fence boards.
5. Check the thickness of the existing infeed
fence board.
— if the infeed fence board is the same
width as the outfeed fence board, remove
the fasteners securing it to the support
board, then remove the infeed fence board.

Edge Jointing
Table Inserts
the Model h7507 features a 29 x 99mm insert
and a 60 x 99mm insert that fit into the opening
on the router table.
the smallest size table opening provides maxi-
mum support and stability to the workpiece during
operation, which increases safety.
using the smallest-size opening also allows any
unused portion of the router bit to remain below
the table surface, which increases operator pro-
tection.
after installing the insert, use a ruler to make sure
it is flush with the router table surface.
