Electronic Feedback Circuitry; Placing The Router Onto The Workpiece And Starting The Cut - Craftsman 320.27683 Operator's Manual

The speed charts on the preceding page indicate the relationship between
the speed setting and the cutting application. Exact settings are determined
through operator experience and preference, and also by recommendations by
manufacturers of cutter bits.
ELECTRONIC FEEDBACK CIRCUITRY
The router electronic feedback circuitry monitors and adjusts power to maintain
the desired speed for consistent performance and control, providing constant
speed under load for a high-quality finish in all materials.
PLACING THE ROUTER ONTO THE WORKPIECE AND STARTING THE CUT
NOTE: Making test cuts is essential with most routing applications. A test cut
will give a feel for the set-up, the router's speed, the depth of cut, and how the
cutting bit reacts to the workpiece.
Much of routing is a trial-and-error process of making various adjustments,
followed by test cuts. To avoid ruining good material, make test cuts on
scrap materials.
How you place your router onto a workpiece (starting the cut) with a fixed base
or a plunge base depends on the type of routing you are going to produce: Edge
Routing or Internal Routing, as discussed on the following pages.
DEEP CUTS
The proper cutting depth for each pass is always determined by the material, the
cutter bit size and type, and power of the motor.
Always make several progressively deeper cuts: start at one depth and then make
several passes, each time increasing the cutting depth, until your desired depth is
reached.
Making a cut that is too deep will stress the router motor and the cutter bit,
and it may burn the workpiece and dull the cutter bit. It could also "grab" too
much of the workpiece and cause you to lose of control of the router, causing a
serious accident.
To be certain that your depth settings are correct, always make test cuts in
scrap material similar to your workpiece before beginning the final cutting
operation.
Remember, knowing the right depth for each
cut comes with routing experience. Fig. 17
EDGE ROUTING OR INTERNAL ROUTING
For ease of operation and to maintain proper
control, your router has two handles, one on
each side of the router base. When operating
the router, always hold it firmly with both
hands (Fig. 17 and 17a).
