Electronic Variable Speed Control; Dial Setting - Craftsman 320.27683 Operator's Manual

ELECTRONIC VARIABLE SPEED CONTROL (Fig. 16}
The electronic speed control feature allows
motor speed to be matched to cutter size and Fig. 16
material for an improved finish and extended
bit life.
Speed changes are made starting at "1" and
rotating the Speed Control Dial to the "LEFT"
to increase the speed, and to the "RIGHT" to
decrease the speed as indicated on the Dial,
numbered 1 through 6.
NOTE: The speed may be changed while the
router is "ON", but not if the cutter bit is in the
workpiece.
Your router motor top cap has a "Variable Speed Selection Chart," located
above the "ON/OFF" toggle switch, to help you determine the correct speed for
the cutter bit being used.
WARNING: Before operating your router, follow all safety instructions in this
manual. Failure to do so could result in serious personal injury.
NOTE: Choose the applicable cutting speed according the bit diameter and the
material being cut.
Variable Speed Selection Chart
Never exceed these bit speeds
Cutting-Bit Diameter Speed
UP to 1in .(25mm) 6
1-1/4 in. to 2in. (30-50mm) 4-5
2-1/4 in. to 2-1/2 in. (55-65 mm) 2-3
3 in. to 3-1/2 in. (75-90mm) 1-2
Reduce the speed when using extra large bits (with a cutting diameter 1 inch or
greater) or heavy cutting bits. Changing the rate of feed can also improve the
quality of the cut.
