USING THE TOOL
Periodically wipe the columns clean with a dry cloth. DO NOT lubricate columns.
IMPORTANT: Before using your router, consider the kind and total amount of
material to be removed. Depending on the material, it may be necessary to make
more than one cut to avoid overloading the motor. Before beginning the cut on
the actual workpiece, make a sample cut on a piece of scrap lumber. This will
show exactly how the cut will look as well as enable you to check dimensions.
Generally speaking, when working on a bench, hold the workpiece on the bench
by wood clamps. When routing edges, hold the router firmly down and against
the work by both handles.
Since the cutter rotates clockwise (when viewing router from top), you can cut
more efficiently if the router is moved from left to right as you stand facing the
work. When working on the inside of a templet, move the router in a clockwise
direction. When working on the outside of a templet, move the router in a counter-
clock-wise direction.
opposite that shown in Fig. 12). "Climb-
Cutting increases the chance for loss
of control resulting in possible personal
injury. When "Climb-Cutting" is required
(backing around a corner), exercise
extreme caution to maintain control of
router.
The speed and depth of cut will depend
largely on the type of material being worked
upon. Keep the cutting pressure constant but do not crowd the router so that
the motor speed slows excessively. More than one pass may be necessary on
exceptionally hard woods or problem materials to get the desired depth of cut.
When making cuts on all four edges of the workpiece, make the first cut on the
end of the piece across the grain. Thus, if chipping of wood occurs at the end of a
cut, it can be removed when making the next cut parallel with the grain.
An accessory edge guide is available to aid in straight edge planing, parallel
grooving, dado, or slotting operations.
To attach, insert the
grooved end of the guide
rods (W) Fig. 13, in holes
in base and secure with
two screws (X). (NOTE:
These screws should
engage the groove in the
guide rod.) Slide the guide
(Y) Fig. 13 on the rods,
and adjust to the desired
position. Secure with the
two thumb screws (Z).
When through-cutting, be sure the router bit has enough
clearance under workpiece.
Firmly clamp or otherwise secure the workpiece before making
a cut.
Avoid "Climb-Cutting"
