Read all safety warnings and all instructions. Failure to follow the warnings
and instructions may result in electric shock, fire and/or serious injury.
SAVE ALL WARNINGS AND INSTRUCTIONS FOR FUTURE REFERENCE
The term “power tool” in the warnings refers to your mains-operated (corded) power tool or
battery-operated (cordless) power tool.
Work area safety
Keep work area clean and well lit. Cluttered
or dark areas invite accidents.
Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gases or dust. Power
tools create sparks which may ignite the dust
or fumes.
Keep children and bystanders away while
operating a power tool. Distractions can
cause you to lose control.
Electrical safety
Power tool plugs must match the outlet.
Never modify the plug in any way. Do not
us e a ny adapter pl ug s with earthe d
(grounded) power tools. Unmodified plugs
and matching outlets will reduce risk of electric
shock.
Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges
and refrigerators. There is an increased risk
of electric shock if your body is earthed or
grounded.
Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
Do not abuse the cord. Never use the cord
for carrying, pulling or unplugging the power
tool. Keep cord away from heat, oil, sharp
edges or moving parts. Damaged or entangled
cords increase the risk of electric shock.
When operating a power tool outdoors,
use an extension cord suitable for outdoor
use. Use of a cord suitable for outdoor use
reduces the risk of electric shock.
If operating a power tool in a damp location
is unavoidable, use a Ground Fault Circuit
Interrupter (GFCI) protected supply. Use of
an GFCI reduces the risk of electric shock.
Personal safety
Stay alert, watch what you are doing and
us e co mmon sense w hen opera ting a
power tool. Do not use a power tool while
you are tired or under the influence of drugs,
alcohol or medication. A moment of inattention
while operating power tools may result in
serious personal injury.
Use personal protective equipment. Always
wear eye protection. Protective equipment
such as dust mask, non-skid safety shoes, hard
hat, or hearing protection used for appropriate
conditions will reduce personal injuries.
Prevent unintentional starting. Ensure the
sw itch is in th e o ff-po sitio n b efore
connecting to power source and / or battery
pa ck, picki ng up or carrying the t ool.
Carrying power tools with your finger on the
switch or energizing power tools that have the
switch on invites accidents.
Remove any adjusting key or wrench before
turning the power tool on. A wrench or a
key left attached to a rotating part of the
power tool may result in personal injury.
Do not overreach. Keep proper footing and
balance at all times. This enables better
co ntrol of the power tool in unexpe ct ed
situations.
Dress properly. Do not wear loose clothing
or jewelry. Keep your hair, clothing and
gloves away from moving parts. Loose
clothes, jewelry or long hair can be caught in
moving parts.
If devices are provided for the connection
of dust extraction and collection facilities,
ensure these are connected and properly
used. Use of dust collection can reduce dust-
related hazards.
Power tool use and care
Do not forc e the power to ol. Use the
correct power tool for your application. The
correct power tool will do the job better and
safer at the rate for which it was designed.
Do not use the power tool if the switch does
not turn it on and off. Any power tool that
ca nn ot be co nt ro lled with the swi tc h is
dangerous and must be repaired.
Disconnect the plug from the power source
and/or the battery pack from the power tool
before making any adjustments, changing
accessories, or storing power tools. Such
preventive safety measures reduce the risk of
starting the power tool accidentally.
Store idle power tools out of the reach of
children and do not allow persons unfamiliar
with the power tool or these instructions to
operate the power tool. Power tools are
dangerous in the hands of untrained users.
Maintain power tools. Check for misalignment
or binding of moving parts, breakage of
parts and any other condition that may
affect the power tool’s operation. If damaged,
have the power tool repaired before use.
Ma ny acci de nt s ar e ca us ed by poorly
maintained power tools.
Safety Rules for Routers
Hold power tool by insulated gripping
surfaces, because the cutter may contact
its own cord. Cutting a ”live” wire may make
exposed metal parts of the power tool ”live”
and shock the operator.
Use clamps or another practical way to
secure and support the workpiece to a
stable platform. Holding the work by your
hand or against the body leaves it unstable
and may lead to loss of control.
If cutting into existing walls or other blind
areas where electrical wiring may exist is
un av oi da bl e, disconnect all fu se s or
circuit breakers feeding this worksite.
Always make sure the work surface is
free from nails and other foreign objects.
Cutting into a nail can cause the bit and the
tool to jump and damage the bit.
Never hold the workpiece in one hand and
the tool in the other hand when in use.
Never place hands near or below cutting
surface. Clamping the material and guiding
the tool with both hands is safer.
Never lay workp ie ce on top of hard
surfaces, li ke co nc re te, stone, etc. ..
Protruding cutting bit may cause tool to jump.
Alway s wear safety goggles and dust
mask. Use only in well ventilated area.
Using personal safety devices and working in
Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting
edges are less likely to bind and are easier to
control.
Use the power tool, accessories and tool
bits etc. in accordance with these instructions,
taking into account the working conditions
and the work to be performed. Use of the
power tool for operations different from those
intended could result in a hazardous situation.
Service
Have your power tool serviced by a qualified
re pa ir person u sing on ly identical
replacement parts. This will ensure that the
safety of the power tool is maintained.

After changing the bits or making any
adjustments, make sure the collet nut and
any ot her ad justmen t devices are
se cu re ly ti gh tened. L oo se ad ju st ment
device can unexpectedly shift, causing loss
of control, loose rotating components will be
violently thrown.
Never start the too l wh en the bi t is
engaged in the material. The bit cutting
edge may grab the material causing loss of
control of the cutter.
The direction of feeding the bit into the
material is very important and it relates to
the direction of bit rotation. When viewing
th e tool from t he to p, the bit rot at es
clockwise. Feed direction of cutting must
be counter-clockwise. NOTE: inside and
outside cu ts will req ui re differe nt feed
direction, refer to section on feeding the
router. Feed in g the tool in the wro ng
direction, causes the cutting edge of the bit
to climb out of the work and pull the tool in
the direction of this feed.
Never use dull or damaged bits. Sharp
bits must be handled with care. Damaged
bits can snap during use. Dull bits require
more force to push the tool, possibly causing
the bit to break.
Never touch the bit during or immediately
after the use. After use the bit is too hot to
be touched by bare hands.
Never lay the tool down until the motor
has come to a complete standstill. The
Additional Safety Warnings
GFCI and personal protection devices like
electrician’s rubber gloves and footwear will
further enhance your personal safety.
Do not use AC only rated tools with a DC
power supply. While the tool may appear to
work, the electrical components of the AC
rated tool are likely to fail and create a hazard
to the operator.
Keep handles dry, clean and free from oil
and grease. Slippery hands cannot safely
control the power tool.
Use clamps or other practical way to secure
and support the work pie ce to a stable
platform. Holding the work by hand or against
your body leaves it unstable and may lead to
loss of control.
Develop a periodic maintenance schedule
for your tool. When cleaning a tool be
careful not to disassemble any portion of

FIG. 13
WORKPIECE
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
workpiece, not away. Figure 14 shows proper
feed for vario us 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
ve ry sl owly or leaves an imperfect cu t,
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.
and plastics, the best finishes will result if the
depth of cut and feed rate are regulated to
keep the motor operating at high speed. Feed
the router at a moderate rate. Soft materials
require a faster feed rate than hard materials.
The router may stall if improperly used or
overloaded. Reduce the feed rate to prevent
possible damage to the tool. Always be sure
the collet chuck is tightened securely before
use. Always use router bits with the shortest
cutting len gth necessa ry t o pr oduce the
desired cut. This will minimize router bit run-out
and chatter.
It may be necessary to make the cut in more
than one pass with progressively deeper
settings to avoid overloading the motor. If the
bit cuts freely and the motor does not slow
down, the cutting depth is generally correct.
GUIDING THE ROUTER
The router can be guided through the work in
any of several ways. The method you use
depends, of course, on the demands of the
particular job and on convenience.
For routing operations such as grooving or
dadoing, it is often necessary to guide the tool
in a line parallel t o a st raight edg e. One
method of obtaining a straight cut is to securely
clamp a board or other straightedge to the
work surface, and guide the edge of the router
sub-base along this path (Fig. 15).
PR002 STRAIGHT ROUTER GUIDE
(Included with PR20EVSK & PR20EVSNK,
also available as optional accessory)
The router guide is an optional accessory that
will guide the router parallel to a straight edge
(Fig. 16).
The router guide is supplied in two parts held
together with a bolt, wing nut and washer. It
also includes a wing screw and washer to
fasten the guide to the router.
The guide features a scale for accurately
positioning the edge guide relative to the bit.
With the guide installed and adjusted, the
router should be fed normally, keeping the
guide in contact with the edge of the workpiece
at all times.
The route r guide can also be positioned
directly under the router base for operations
where a cut is needed close to or at the edge
of the work, such as when rounding off deck
planks.
ball bearing which rides against the work
surface above or below the cutter to control
horizontal cutting depth (Fig. 17). When using
these bits, neither the roller guide or the
strai ght gui de is required . When guiding
against a laminated surface, use wax or other
lubricant and do not apply excess pressure or
the piloted end may mar the work. Bearing
pilots must be kept clean and free of adhesive
or other residu e. Router bit bearings are
sealed and permanently lubricated, and should
be replaced when they no longer turn freely to
avoid damaging the work surface.
PR003 ROLLER/BUSHING GUIDE
(Included with PR20EVSNK, also available as
optional accessory)
The optional PR003 Roller/Bushing Guide is
used when edge-forming or trimming with
unpiloted bits, non-bearing bits.
Attachment of Roller/Bushing Guide
The PR003 roller/bushing guide (Fig. 18) is
attached using the wing screw and washer.
Adjustment of Roller/Bushing Guide
Vertical Adjustment:
1. Loosen the wing screw and adjust up or
down as necessary to allow roller/bushing to
ride on the intended guiding surface.
2. Tighten wing screw.
Horizontal Adjustment:
Whether making straight or bevel cuts, the
width of material removed is determined by the
distance between the front of the router bit’s
cutter and the front of the roller/bushing. Adjust
the front of the roller/bushing as follows:
1. Loosen wing nut at bottom.
2. Rotate the wing nut on the back of the guide
to move the roller/bushing in or out to create
amount of cutter exposure needed to trim
the laminate flush with the guiding surface or
to create the desired bevel.
3. Be sure the bi t clears th e to p of the
roller/bushing guide by at least 1/8" (3 mm)
to avoid damage.
4. Tighten wing nut on the bottom of the guide
assembly
5. Make a trial cut to check the setting and
readjust as necessary.

FIG. 18
Use of the Roller/Bushing Guide
1. With the guide installed and adjusted, the
router should be fed normally, keeping the
gu ide in contac t wit h the edge of the
workpiece at all times.
2. To maintain a consistent width of cut, a
co nsistent an gle must be mainta ined
between the router and the workpiece.
(Available as optional accessories)
Optional large round subbases are available
separately and allow various templet guide
bushings to be used with the palm routers.
Templet guide bushings are used to guide the
router to repeatedly make consistent openings
and inlays using various templets (also referred to
as patterns and jigs). Templets for standard
routing applications are available commercially,
such as the Bosch hinge templet kit; and templets
for specialty applications are typically made by
users for their specific needs.
The PR009 Round Subbase accepts the Bosch
RA-Series Templet Guide Adapters.
The PR010 Round Subbase accepts threaded
templet guide adapters.*
*Note: The RA1100 Adapter for Threaded
Templets allows use of conventional threaded
templet guides with the PR009 Round Subbase.
PR009 Attachment of Templet Guide and
Round Subbase (Fig. 19)
1. Remove regular subbase.
2. Insert templet guide into top of round subbase
such that the anti-rotation stops in the subbase

Creating Templets
Templet patterns can be made of plywood,
hardboard, metal or even plastic. The design can
be cut with a router, jigsaw, or other suitable
cutting tool. Remember that the pattern will have
to be made to compensate for the distance
between the router bit and the templet guide (the
“offset”), as the final workpiece will differ in size
from the templet pattern by that amount, due to
the bit position (Fig. 22).
*See page 26 for available templet guide sizes.
**See page 25 for details about centering.
The PR004 Offset Base is designed for routing
in confined areas, especially for trimming
laminates in areas that are inaccessible with
the standard fixed base, such as locations that
are close to adjacent vertical surfaces like as
the tops of already-installed counter backsplash
backsplashes (Fig. 23).
The PR004 allows routing extremely close to
vertical surface in front of the tool, as close as
1/2” when 3/4” bit is used (Removal of the black
offset spindle cover further reduces distance
from 3/4” bit and vertical surface to 3/8”.) The
1-1/16” base opening makes it possible to use
bits that have cutters as wide 13/16”.
The PR004 can also be used to scribe the back
of a new counter backsplash so that it will mate
precisely with the wall against which it will rest

one in the PR004 Offset Base creates more
heat than when the motor is used in its other
bases. To help minimize heat build-up, the
PR004 has been designed with large bearings,
specially-designed heat sinks, carefully-directed
airflow and plastic heat shields. Depending on
the application, the PR004 Offset Base can be
used for up to about 10 minutes continuously
before it will need to be left idle so that it can
cool off.
1. Remove collet from motor and install toothed
drive pulley using collet wrench. Make sure
that drive gear is fully tightened onto the
motor’s spindle. (Fig. 25)
2. The motor is then installed into the base
according to the instructions on page 9.
3. Insert screwdriver (not included) through the
U-shaped opening in the subbase to fit belt
over drive pulley. (Fig. 26)

WARNING
To reduce the risk of injury,
do not use the offset base
2. Press large red spindle lock button on top of
offset spindle (Fig. 27).
3. Tighten collet nut using the same collet
wrench as is used on the motor’s own collet
nut. (The collet used on the PR004 is the
same type of self-releasing collet used on
the motor itself when used with the other
bases.)
4. Make a trial cut to check the depth and
readjust as necessary.
Using the Offset Router
The principles of using the offset router are
basically the same as for the fixed-base router
set-up (motor in fixed-base assembly), with the
following differences
1. The offset router should be gripped with one
hand gripping the motor gripping area and
the other hand gripping the back of the base
housing (Fig. 23) or gripping the top of the
offset spindle.
2. For routing backsplashes and other elevated
workpieces, some installers mount the offset
base to a wood block that matches the
height of the laminated backsplash. This
he lps to mai ntain a consisten t an gle
between the bit’s cutter and the workpiece
and to provide addition stability.
Offset Base Roller/Bushing Guide
The PR004’s roller/bushing guide is required
when edge-forming or trimming with unpiloted
non-bearing bits.
Attachment of Roller/Bushing Guide
The PR004’s roller/bushing guide is attached
using two screws with a Philips screwdriver
(not included). Fig. 28
Adjustment of Roller/Bushing Guide
Whether making straight or bevel cuts, the
width of material removed is determined by the
distance between the front of the router bit’s
cutter and the front of the roller/bushing. Adjust
the front of the ro ller/bushing as follows
(Fig. 29):
1. Using a Phillips screwdriver, to adjust,
loosen screw.
2. Rotate the knurled knob on back of the
guide to move the roller/bushing in or out to
create amount of cutter exposure needed to
trim the laminate flush with the guiding
surface or to create the desired bevel.

3. Be sure the bi t clears th e to p of the
roller/bushing guide by at least 1/8" (3 mm)
to avoid damage.
4. Tighten clamping screw using a Phillips
screwdriver.
5. Make a trial cut to check the setting and
readjust as necessary.
Use of the PR004 with
Roller/Bushing Guide
1. With the guide installed and adjusted, the
router should be fed normally, keeping the
gu ide in contac t wit h the edge of the
workpiece at all times.
2. To maintain a consistent width of cut, a
co nsistent an gle must be mainta ined
between the router and the workpiece.
The PR005 Tilt Base (Fig. 30) is used for the
following purposes:
• Trimming laminated edges at the point that
they reach adjacent vertical surface, such as
a kitchen counter’s backsplash (Fig. 32).
• Trimming special angles (Fig. 31)
• Making bevel cuts. One method of obtaining
a consistent bevel cut is to securely clamp a
board or other straightedge to the work
surface, and guide the edge of the router
subbase along this path (Fig. 15).
Th e motor is inst al led acc ording to the
instructions on page 9.
The total tilt range is 75°, from 45° forward to
30° backward.
To adjust the angle (Fig. 32):
1. Loosen the two wing screws.
2. Adjust the angle as desired using the scale
on the left side of the base. Note that there
ar e de tents at ev ery 7.5°. Whene ver
possible, the base should be positioned with
the motor tilted toward the closed end of the
base.
3. Tighten the wing screws. Be careful not to
over-tighten, or the base may be damaged.
Th e depth is adjust ed ac cording to the
instructions on page 12.
The principles of using the tilt router are
basically the same as for the regular router setup (motor in fixed-base assembly), with the
following difference.
1. The PR005 should always be used with a
self-piloted or bearing bit.
2. The proper grip position depends on the
angle of the cut and the tool. The router
should be gripped with one hand gripping
th e motor and the other gripp ing the
elsewhere on the back of the tool.

above or next to the exposed bit.
3. When trimming edges while the bit is tilted
toward the direction of feed, it is extremely
important to keep the base square with the

Bit Height Adjustment
After installing the bit, the height should be
adjusted as follows:
FIG. 35
1. Lower bit until it just enters the recess that is
machined in the underscribe attachment’s
aluminum plate.
2. The tool is now ready for making a test cut.

aluminum plate.
2. Using the pin wrench, adjust the eccentric
adjuster as follows:
• For a tigh ter seam, turn the e ccentri c
adjuster clockwise (as viewed from under
the base)
• For a loo ser se am, tu rn the eccentric
adjuster counterclockwise, (as viewed from
under the base)
3. Retighten the screws
4. Make a test cut
5. Repeat steps 1-4 as necessary
Creating a Seam
1. To create a precision seam, make sure he
guiding pi ece of la min ate has a clean,
straight edge, because it will serve as the
guide for the underscribe attachment.
2. Contact cement should be applied to the
substrate core material and the guiding
piece of laminate up to 1” from its guiding
edge.
3. The overlapping piece of laminate should
overlap the guiding piece by about 1/2".
(The overlapping sheet of laminate will then
pass over the aluminum plate and be cut at
the proper point by the router bit.)
4. Keep steady pressure on the tool so that the
guiding edge of the base remains in contact
with the fixed piece of laminate throughout
the operation. This is especially important at
the beginning and end of a cut.
5. It is also necessary to keep the laminate
pressed down tightly near the seam to keep
these chips from getting under the laminate.
This is especially important on larger pieces
of materia l. The op tional PR0 07 Side
Handle Subbase includes a dust extraction
hood port that connects to a vacuum hose
and helps to keep chips from getting under
the laminate.
PR007 SIDE-HANDLE SUBBASE
(Available as optional accessory)
See PR007 instruction sheet for complete
information about this accessory.
The PR007 Side-Handle Subbase and Dust
Extraction Kit (Fig. 36) is a versatile accessory
that provides several useful features:
FIG. 36
• Additional means of supporting the router
• Dust extraction and collection capability
PR007 Attachment to PR001 Fixed base
1. Remove regular subbase
2. Attac h si de handle sub base with the
panhead screws that are included with it.
Additional Means of Supporting
the Router
The kno b handle on the PR007 subbase
provides an additional gripping point for the
palm router / side-handle subbase assembly. It
is designed for use when the palm routers are
being use d in applic ations that are wide
enough that the knob sits over the workpiece.
Holding the knob and keeping it pressed down
over the workpiece helps keep the routers’
angle to the workpiece unchanged, and is
especially helpful when routing edges.
Attachment of PR006 Underscribe
The PR006 Underscribe Attachment can also
be used with the palm router and the sidehandle subbase.
Note: When the underscribe attachment is
used with the side-handle subbase, the longer
set of attachment screws should be used.

2. Next, lower the depth rod until it contacts
the jig.
3. Secur e t he rod in position by fi rm ly
tightening the depth indicator knob.
4. Finally, remove the jig.
DEEP CUTS
For deeper cuts, make several progressively
deeper cuts by starting with the highest step on
the depth turret, and after each cut, rotate the
depth turret to progressively lower steps as
desired, until the final depth (lowest step or flat)
is reached. Steps progress by 1/8” increments.
To be certain that your depth settings are as
desired, you may want to make test cuts in
scrap material before beginning work.
