General Power Tool Safety Warnings |
|
Read all safety warnings and all instructions. Failure to follow the warnings |
! WARNING |
|
|
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 use any adapter plugs with earthed (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 use common sense when operating 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 switch is in the off-position before connecting to power source and / or battery pack, picking up or carrying the tool.
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 control of the power tool in unexpected 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 dustrelated hazards.
Power tool use and care
Do not force the power tool. 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 cannot be controlled with the switch is dangerous and must be repaired.

BM 2610021461 06-12_BM 2610021461 06-12.qxp 6/26/12 1:38 PM Page 3
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.
Many accidents are caused by poorly maintained power tools.
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 repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.
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 unavoidable, disconnect all fuses 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 workpiece on top of hard surfaces, like concrete, stone, etc...
Protruding cutting bit may cause tool to jump.
Always wear safety goggles and dust mask. Use only in well ventilated area.
Using personal safety devices and working in
safe environment reduces risk of injury.
After changing the bits or making any adjustments, make sure the collet nut and any other adjustment devices are securely tightened. Loose adjustment device can unexpectedly shift, causing loss of control, loose rotating components will be violently thrown.
Never start the tool when the bit 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 the tool from the top, the bit rotates clockwise. Feed direction of cutting must be counter-clockwise. NOTE: inside and outside cuts will require different feed direction, refer to section on feeding the router. Feeding the tool in the wrong 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.
-3-
BM 2610021461 06-12_BM 2610021461 06-12.qxp 6/26/12 1:38 PM Page 4
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
spinning bit can grab the surface and pull the tool out of your control.
Cutter diameter must be at least 1/4” smaller than opening for the bit and cutter.
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 workpiece 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 the tool since internal wires may be misplaced or pinched or safety guard return springs may be improperly mounted.
Certain cleaning agents such as gasoline,
carbon tetrachloride, ammonia, etc. may damage plastic parts.
Risk of injury to user. The power cord must only be serviced by a Bosch Factory Service Center or Authorized Bosch Service Station.
Some dust created by power sanding, sawing, grinding, drilling, and other construction activities
contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:
•Lead from lead-based paints,
•Crystalline silica from bricks and cement and other masonry products, and
•Arsenic and chromium from chemicallytreated lumber.
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.

Assembly
SELECTING BITS
Your Bosch palm router is designed for a wide variety of routing applications that use 1/4" shank bits. These include woodworking applications such as edge forming, grooving, and sign making. This router is also ideal for trimming laminates, phenolics, and other materials that have been bonded to a substrate overhang the substrate typically by about 1/8" (3 mm).
A wide assortment of router bits with different profiles are available as accessories. Only use good quality bits.
To prevent personal injury, ! WARNING always remove the plug
from power source before removing or installing bits or accessories.
Installing a Router Bit *
1.Lay the router or motor on its side (unless router is in the plunge-base router configuration). The router can also be stood "on its head" for bit changes, such as when in the plunge-base configuration.
2.Press spindle lock to prevent rotation of collet chuck. NOTE: it may be necessary to rotate collet nut to engage spindle lock (Fig. 3).
3.Next, use the collet wrench to loosen the collet chuck assembly in a counter-clockwise direction (viewed from bottom of router).
4.Insert the shank of the router bit into the collet chuck assembly as far as it will go, then back the shank out until the cutters are approximately 1/8" to 1/4" away from the collet nut face.
5.With the router bit inserted and the spindle lock engaged, use the collet wrench to firmly tighten the collet chuck assembly in a clockwise direction (viewed from bottom of router) (Fig. 4).
To ensure proper gripping of the router bit and minimize run-out, the shank of the router bit must be inserted at least 5/8".
Cutter diameter must be at least 1/4” smaller than
opening for the bit and cutter.
! CAUTION |
To prevent damage to tool, |
|
|
do not tighten collet without |
|
a bit. |

(BASE REMOVED FOR CLARITY)
*As an alternative to the spindle lock, the thin 10mm wrench can be used on the ‘flats’ of the spindle.
NOTE: The bit shank and chuck should be clean and free of dust, wood, residue and grease before assembling.
Removing the Router Bit*
1.Press spindle lock to prevent rotation of collet chuck, and turn the collet chuck assembly in a counter-clockwise direction.
2.Once the collet chuck assembly is loosened, continue to turn the collet chuck assembly until it pulls the collet free from the spindle, and the router bit can be removed.
NOTE: The collet chuck is self-extracting; it is NOT necessary to strike the collet chuck to free the router bit.

COLLET CHUCK CARE
With the router bit removed, continue to turn the collet chuck counter-clockwise until it is free of the shaft. To assure a firm grip, occasionally blow out the collet chuck with compressed air, and clean the taper in the armature assembly shaft with a tissue or fine brush. The collet chuck is made up of two component parts that snap together (Fig. 5); check to see that the collet is properly seated in the collet chuck nut and lightly thread the collet chuck back onto the armature shaft. Replace worn or damaged collet chucks immediately.
REMOVING MOTOR FROM BASE
1.Open the clamping lever (Fig. 6).
2.Turn the motor so that the single triangle on the base lines up with “unlocked” symbol on the motor. (Make sure that the single triangle the base is aligned with the line under the “unlocked” symbol on the motor. Otherwise, the router can be damaged.) (Fig. 6)
3.Pull the motor away from base until it stops (Fig. 6).
4.Turn motor counterclockwise until it stops (Fig. 7).
5.Pull motor out of base (Fig. 7).

6.Close the clamping lever. Always make sure the motor sits tightly in the base. (The tension of the clamping lever can be changed by re-adjusting the nut.) (Fig. 10)
CHECK SUBBASE LOCATION
Make sure that the bit and its cutter are centered in the subbase opening. If necessary, adjust the location of the subbase as follows:
1.Loosen the four screws that hold the subbase.
2.Adjust the location of the subbase as needed so that the bit and its cutter are centered in the subbase opening. The optional RA1151 centering device makes this easy.
3.Tighten the four screws that hold the subbase (Fig. 11).
Cutter diameter must be at least 1/4” smaller than
opening for the bit and cutter.
When the subbase has been centered in this manner, the left and right edges of the subbase are equidistant from the cutter, and either side of the subbase can be used as a guiding surface without worrying about a difference in the cut line. See "Guiding The Router" on page 13.
Note: This subbase is not designed for use with templet guides. See optional PR009 and PR010 Accessories for use of templet guides with the palm router.

6.Make a trial cut to verify that the router is set to make the cut as desired.
TO CLAMP MOTOR
When final macro and fine adjustments have been made, fasten the base clamp lever to secure adjustments. (If additional clamping force is desired: using a 8 mm wrench, rotate clamp nut clockwise SLIGHTLY (1/8 turn or less), then test clamp. Do not over-tighten.)
DEEP CUTS
For deep cuts, make several progressively deeper cuts by starting at one depth and then make several subsequent passes, increasing the cutting depth with each pass.
To be certain that your depth settings are as desired, you may want to make test cuts in scrap material before beginning work.

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 resetting 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).
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
EDGE
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.

BM 2610021461 06-12_BM 2610021461 06-12.qxp 6/26/12 1:38 PM Page 14
RATE OF FEED
When routing or doing related work in wood 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 length necessary to produce 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 to a straight edge. 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 router 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.

USING SELF-PILOTED BITS
Self-piloted bits have an integral round tip or 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 straight guide 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 residue. 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 bit clears the top 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. 17
FIG. 18
Use of the Roller/Bushing Guide
1.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.
2.To maintain a consistent width of cut, a consistent angle must be maintained between the router and the workpiece.

PR009 AND PR010 ROUND SUBBASES & USE OF TEMPLET GUIDE BUSHINGS WITH PR001 FIXED BASE
(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 fit into the corresponding places in the templet guide. (When using the RA1100 adapter, first place the rubber O-ring between the antirotation stops and the subbase.) (Fig. 20).
3.Loosely attach round subbase using panhead screws that come with that accessory.
4.Center the templet guide around the bit. (The optional Bosch RA1150 Centering Cone can be used to ensure that the templet guide is properly centered.)**
5.Tighten the panhead screws to hold the templet guide and subbase in position.
Note: If a templet guide seems loose, repeat steps 2- 5 after adding the rubber O-ring.

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.

PR004 OFFSET BASE
(Included with PR20EVSNK. Also available as optional accessory)
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 (Fig. 24).
Heat Build-Up
To reduce the risk of injury, ! WARNING do not use the offset base
for more than 10 minutes continuously.
Prolonged continuous use will result in the tool becoming hot to the touch.
The nature of a belt drive mechanism like the 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.
Motor Installation
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)

Installation of Bit
1.Insert bit to the desired depth as per the instructions on page 9.
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 helps to maintain a consistent angle 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 roller/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.

PR005 TILT BASE
(Included with PR20EVSNK. Also available as optional accessory)
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).
Motor Installation
The motor is installed according to the instructions on page 9.
Angle Adjustment
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 are detents at every 7.5°. Whenever 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.
Depth Adjustment
The depth is adjusted according to the instructions on page 12.
Using the Tilt Router
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 the motor and the other gripping the elsewhere on the back of the tool.
To reduce the risk of injury, never grip the base directly
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

PR006 UNDERSCRIBE ATTACHMENT
(Included with PR20EVSNK. Also available as optional accessory)
The PR006 Underscribe Attachment is used to create precision-fit seams between two sheets of laminate (Fig. 33), such as stile and rail constructions and very large surfaces. It is attached to the bottom of the PR001 Fixed Base or PR011 Plunge Base. See PR011 Plunge Base for use of PR006 with that base.
Installation (Fig. 34)
1.Remove rear screws used to hold subbase onto PR001 Fixed Base.
2.Attach infeed side of PR006 to the Fixed Base using hex screw*
3.Insert eccentric adjuster into pocket on outfeed side of PR006.
4.Attach outfeed side of PR006 to the Fixed Base using hex screw*
*When used with PR007 Side-Handle Base, the longer set of attachment screws should be used.
Bit Installation
•The recommend bit for use with the Underscribe Attachment is the Bosch 85213M with 1/8” cutting diameter.
•It should be installed according to the instructions on page 9.
Bit Height Adjustment
After installing the bit, the height should be adjusted as follows:
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.
Front-to-Back Adjustment
If necessary, the cutting point can be adjusted front-to-back as follows (Fig. 35):
1.Loosen the two screws holding the aluminum plate.
2.Using the pin wrench, adjust the eccentric adjuster as follows:
•For a tighter seam, turn the eccentric adjuster clockwise (as viewed from under the base)
•For a looser seam, turn the eccentric adjuster counterclockwise, (as viewed from under the base)
3.Retighten the screws

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 material. The optional PR007 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

DEPTH ROD AND TURRET
The depth rod and the depth stop turret are used to control cutting depth as follows;
1.With the bit installed, gently lower the motor until the tip of the router bit just contacts the level surface the router is sitting on. This is the “zero” position, from which further depth adjustments can be accurately made.
2.Rotate depth stop turret until the lowest step is aligned with the depth rod. Loosen depth indicator knob and lower the depth rod until it contacts the lowest step of the turret. Slide the depth indicator until the red line indicates zero on the depth scale, indicating the point at which the bit just contacts the work (Fig. 40).
3.Slide the depth rod up until the red depth indicator line attains the desired cutting depth, and secure the rod in position by firmly tightening the depth indicator knob.
4.The desired depth of cut may now be achieved by plunging the router until the depth rod contacts the lowest stop on the turret.
ALTERNATE SET-UP FOR
DEPTH ROD AND TURRET
1.An alternative to place a jig of the desired routing depth (such as a hinge which needs to be mortised) on the bottom step of the turret.
2.Next, lower the depth rod until it contacts the jig.
3.Secure the rod in position by firmly 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.

The PR011 plunge base is equipped with a fine adjustment system that allows you to micro adjust the plunge depth of the router bit for superior routing accuracy.
Each complete revolution of the fine adjustment knob adjusts the plunging depth by 1/32”, and each of the four indicator marks on the knob represents 1/128”.

DEPTH STOP
TURRET
To use the fine adjustment knob, once the depth rod and turret have been set, check the final depth setting and fine-adjust as follows:
To micro-increase the plunge depth, raise the fine adjustment stop by turning it counterclockwise by the desired amount.
To micro-reduce the plunge depth, lower the fine adjustment stop by turning it clockwise by the desired amount.
Notes:
•When micro-adjusting the plunge depth, it is more convenient to move the fine adjustment stop up than down. Before setting the depth rod and turret, make sure the fine adjustment stop has been turned several revolutions down from its top position so that it can be adjusted upward.
•The fine adjustment stop cannot be used to reduce the plunge depth when the depth rod is already touching the depth stop turret.
The router must be raised before such an adjustment can be made.
THE PR012 ROUTER DUST COLLECTION
FOR PLUNGE BASE
This dust extraction hood is designed for use the plunge base (PR011) when routing is done in the middle of the workpiece, such as when creating slots or routing patterns for inlays. If you have a shop vacuum system, you can attach the dust extraction hood for improved visibility, accuracy and utility, particularly in freehand routing.
To attach, position as shown and secure adapter to base with the thumbscrews provided (Fig. 41).
The dust extraction hood can also be installed with the hose outlet facing the front of the tool.

DELUXE ROUTER GUIDE
(Not included, available as accessory)
The Bosch deluxe router guide is an optional accessory that will guide the router parallel to a straight edge or allow you to create circles and arcs.
The deluxe router guide is supplied with two rods and screws to fasten the guide (Fig. 44). In addition, it features a fine adjustment knob and indicator 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 deluxe router guide may also be positioned directly under the router base for operations where a cut is needed close to or at the edge of the work.
The deluxe router guide includes a dust extraction hood and the VAC002 vacuum hose adapter.
For complete instructions on installation and operation, please refer to the instructions which are included with this accessory.

CENTERING THE SUB-BASE OR
TEMPLET GUIDES
Your PR011 plunge base features the Bosch “Precision Centering Design”. Its subbase is precisely centered at the factory. This positions the bit at the center of the subbase and optional templet guides.
Precision centering allows you to use the edge of the subbase or templet guides to closely follow jigs such as straight guides, templets, and dovetail fixtures without worrying about bit walk-off from the intended cut line for any reason, including the orientation of the router’s handles relative to the jig.
To most precisely re-center the subbase or templet guides, attach the subbase using the optional Bosch RA1151 Centering Device. Follow steps 1-8 (Fig. 47).
1.If a templet guide is to be centered, Install the templet guide adapter and template guide (optional attachments) as described elsewhere in this manual.
2.Loosen the four screws that hold the subbase to the base.
3.Prepare the Centering Device:
•Use narrow end of steel shaft.
•When centering subbase or templet guide that has opening of more than ½”, slide the wide plastic sleeve over the steel shaft.
4.Slide centering sleeve through the subbase or templet guide and into collet. Tighten collet nut with fingers to put slight grip on centering cone.
