Electronic Variable Speed Control; Electronic Feedback Circuitry - Craftsman 320.17542 Operator's Manual

Electronic Variable Speed Control
The electronic speed control feature allows motor speed to be matched to cutter size and
material hardness for an improved finish and extended bit life.
Variable Speed Selection Chart
Never exceed these bit speeds
Cutter Bit Diameter Max. Speed
Up to 1-in. (25mm) 6
11/4-in. to 2-in. (30-50mm) 4 - 5
2!/4-in. to 21/2-in. (55-65 mm) 2 - 3
3-in. to 31/2-in. (75-90mm) 1 - 2
Reduce the speed when using extra large l-in., plus, or heavy cutter bits.. Changing the
router's rate of feed can also improve the quality of the cut,

The speed charts above indicate the relationship between speed settings and the
cutting application. Exact settings are determined by operator experience and preference,
and also by recommendations by manufacturers of cutter bits.
ELECTRONIC FEEDBACK CIRCUITRY
The router's electronic feedback circuitry monitors and adjusts power to maintain the
desired RPM for consistent performance and control, providing constant speed under
load for a quality finish in all materials..
PLACING THE ROUTER ONTO THE WORKPIECE AND STARTING THE CUT
Z_ WARNING:
Before operating your router follow all safety instructions ]
in this manual. Failure to do so could result in serious personal injury.
