Stock Inspection & Requirements; Fence Boards - Grizzly T1240 Owner's Manual

Stock Inspection &
Requirements
Follow these rules when choosing and routing
stock:
DO NOT cut stock that contains large or
•
loose knots. Injury to the operator or dam-
age to the workpiece can occur if a knot
becomes dislodged during the cutting opera-
tion.
DO NOT cut against the grain direction.
•
Cutting against the grain increases the like-
lihood of kickback, as well as tearout on the
workpiece.
Routing with the grain produces a better
•
finish and is safer for the operator. Cutting
with the grain is described as feeding the
stock on the router table so the grain points
down and toward you as viewed on the edge
of the stock (see Figure below).
Note: If the grain changes direction along the
edge of the board, decrease the cutting depth
and make additional passes.

bit.
• Scrape all glue off the workpiece before
jointing. Glue deposits on the workpiece,
hard or soft, will gum up the router bit and
produce poor results.
Remove foreign objects from the work-
•
piece. Make sure that any stock you pro-
cess with the router is clean and free of dirt,
nails, staples, tiny rocks, or any other foreign
objects that could damage the router bit and
be thrown from the machine with significant
speed/force.
Note: Wood stacked on a concrete or dirt
surface can have small pieces of concrete or
stone pressed into the surface.
Make sure all stock is sufficiently dried
•
before routing. Wood with a moisture con-
tent over 20% will cause unnecessary wear
on the router bits and poor cutting results.
Excess moisture can also hasten rust and
corrosion.

Fence Boards

The fence on the Model T1240 has two fence
boards (infeed and outfeed). Each fence board
can be moved sideways up to 1" to increase or
decrease the space between the boards and
the router bit. The fence boards are held to the
fence base with flat head screws and wing nuts
(see Figure 20). Use the wing nuts to loosen or
tighten the fence boards to the fence base.
