TRIGGER SWITCH AND
"LOCK-ON" BUTTON
Your router can be turned ON or OFF by
squeezing or releasing the trigger. Your router is
also equipped with a "Lock-ON" button located
to the left of trigger that allows continuous
operation without holding the trigger.

depress button and release trigger (Fig. 2).
TO UNLOCK THE SWITCH: Squeeze trigger
and release it without depressing the "Lock-ON"
button.
If the "Lock-ON" button

is
depressed, the trigger cannot be released.
Always make sure that the bit is not touching the
work when turning the switch on or off. Contact
the work with the router after the router has
reached full speed, and remove it from the work
before turning the switch off. Operating in this
manner will prolong switch and motor life and
will greatly increase the quality of your work.
SOFT START FEATURE
Electronic feedback control minimizes torque
twist customary in larger routers by limiting the
speed at which motor starts.
ELECTRONIC VARIABLE SPEED CONTROL
The electronic speed control feature allows motor
speed to be matched to cutter size and material
hardness for improved finish, extended bit life,
and higher performance. Speed changes are
achieved by rotating Speed Control Dial
FORWARD to decrease speed, BACK to increase
speed, as indicated on housing (Fig. 12). Speed
may be changed while tool is on. The reference
numbers on the dial facilitate re-setting control to
desired speed.
