Electronic Variable Speed Control; Dial Setting - Craftsman 320.28084 Product Manual

Electronic Variable Speed Control (Fig. 23)
The electronic speed control Fig. 23
feature allows router motor
speed to be matched to cutter
size and workpiece-material
hardness for an improved
finish and extended bit life.
Speed changes are made by
rotating the Speed Control Dial
to the "LEFT," starting at "1 ,"
to increase the speed and to
the "RIGHT" to decrease the
speed, as indicated on the Dial.
The router motor top cap has
a "Variable Speed Selection
Chart" located above the "ON/OFF" toggle switch to help determine the correct
speed for the cutting bit being used.
WARNING: Before operating the router follow all safety instructions in this
manual. Failure to do so could result in serious personal injury.

Reduce the speed when using extra large bits (1-inor more in cutting diameter
or heavy cutting bits. Changing the router's rate of feed can also improve the
quality of the cut.
