Controls
ELECTRONIC SPEED CONTROL DIAL
The speed of your router is variable. Use the electronic speed
control (Fig. 3) dial to produce uniform cutting results in wood,
plastics and aluminum. Use the lower settings (1-3) for large
diameter cutters and the higher settings for small diameter cutters.
See Table A for more information.
Your router is equipped with constant speed cutting—as you load
the router, the selected cutting speed does not slow down during
normal use. The electronic control governs the motor and gives you
a consistent finish to your work. Only under very heavy loading will
the speed of the unit fall below the governed speed.
QUICK
To set the router speed (from 8,000 rpm to 24,000 rpm) rotate the
ADJUSTER
speed control wheel shown in Fig. 3. The higher the number the
higher the speed. Consult the table below to help select the proper
speed for your application.
