ROCKER “ON/OFF” SWITCH
Your tool can be turned “ON” or “OFF” by the
rocker switch located on the motor housing.
One side of the switch is marked “I” for “ON“,
and the other side of switch is marked “O” for
“OFF“.

P
ush the side
of the switch marked “I”.
TO TURN THE TOOL “OFF”: Push the side
of the switch marked “O”.
SOFT START FEATURE
Electronic feedback control minimizes torque
twist customary in routers by limiting the
speed at which motor starts.
ELECTRONIC VARIABLE SPEED
CONTROL
(Model PR20EVS Only)
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
Control Dial RIGHT to increase speed, LEFT
to decrease as indicated on housing (Fig. 1).
Speed may be changed while tool is on. The
reference numbers on the dial facilitate re-
setting control to desired speed.
The speed chart indicates the relationship
between settings and application, exact
settings are determined by operator
experience and preference. The bit
manufacturer may also have a speed
recommendation.
CONSTANT RESPONSE™ CIRCUITRY
The router's Constant Response™ Circuitry
monitors and adjusts power to maintain the
desired RPM for consistent performance and
control.
FEEDING THE ROUTER
In addition to the main palm-grip area at the
back of the motor housing and base, the
base has Bosch-exclusive finger support
pockets to provide additional stability for the
router. The pockets feature finger guards to
provide a barrier between the finger pockets
and the bit area (Fig 12).
As seen from the top of the router, the bit
turns clockwise and the cutting edges face
accordingly. Therefore, the most efficient cut
is made by feeding the router so that the bit
turns into the work, not away. Figure 13
shows proper feed for various cuts. How fast
you feed depends on the hardness of the
material and the size of the cut. For some
materials, it is best to make several cuts of
increasing depth.
If the router is hard to control, heats up, runs
very slowly or leaves an imperfect cut,
consider these causes:
1.
Wrong direction of feed — hard to control.
2.
Feeding too fast — overloads motor.
3. Dull bit — overloads motor.
4. Cut is too large for one pass — overloads
motor.
5. Feeding too slow — leaves friction burns
on work.
Feed smoothly and steadily (do not force).
You will soon learn how the router sounds
and feels when it is working best.
Always hold the router off 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.
