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".
TO TURN THE TOOL "ON": Push 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 the
Control Dial RIGHT to increase speed or 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 13).
APPLICATION
}
Larger-diameter bits
and cutters.
Softwoods, plastics,
}
laminates, smaller
diameter bits and
cutters
When using finger pockets,
WARNING
!
always place both finger
pockets over the workpiece and always hold
the router in a way that allows you to see your
finger and thumb.
FIG. 13
WORKPIECE
As seen from the top of the router, the bit turns
clockwise and the bit's cutting edges are
positioned to best cut into the workpiece.
Therefore, the most efficient cut is made by
feeding the router so that the bit turns into the
workpiece, not away. Figure 14 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.
