 Work area safety

Keep work a r e a clean and w e l l 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 ad a p t e r plugs with earthed (grounded) power tools. Unmodified plugs

and matching outlets will reduce risk of electric shock.

Avoid body contact with ea r t h e d or grounded s u r f a c e s such a s 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 w hen oper ating 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 eq u i p m e n t . 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.

2610052572_GKF125CE 9/18/18 12:11 PM Page 2

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, d i s c o n n e c t all fuses or circuit breakers feeding this worksite.

Always make sure the work surface is free fr om na ils a nd ot her f oreign 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 ha r d surfaces, like concrete, s t o n e , etc...

Protruding cutting bit may cause tool to jump.

Al ways wear safety goggl es and dust

Prevent unintentional starting. Ensure the switch is in the off-position before con necting 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.

Rem ove any adjustin g key or wren ch before turning the power tool on. A

wrench or a key left attached to a rotating part of the power to o l may result in personal injury.

Do not overreach. Keep proper footing and balance at all times. This enables

better c o n t r o l of t h e power t o o l 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

dust-related hazards.

 Power tool use and care

Do not force the power t ool. 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.

Disconnect t h e 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 an d do not al l o w 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 m a y affect the p o w e r 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 cl e a n .

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 et c . in accordance with th e s e ins t ructions, taking i n t o accoun t the working conditions and the work to be per f ormed. U se of the powe r 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.

2610052572_GKF125CE 9/18/18 12:11 PM Page 3

mask. Use only in well ventilated area.

Using personal safety devices and working in safe environment reduces risk of injury.

fter 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 rout e r . 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 t

he 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

spinning bit can grab the surface and pull the tool out of your control.

Cutter diameter must be at least 1/4” smal l e r than o p e n i ng for t h e bit a n d cutter.

Additional Safety Warnings

Use only router b its that have shank diameters that match the installed collet.

Using a router bit that has a smaller shank could cause the bit to come loose during operation and become a projectile.

Never operate router bits at speeds that ar e higher than their maxim um rat ed speed. Router bits running faster than their

rated speed can break and fly apart. 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.

Us e cla mps 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 Autho rized 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 ot her 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 chemically-

treated lumber.

Your risk from these exposu res 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.

 Selecting Bits

Your Bosch palm router is designed for a wide variety of ro u t i n g 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 ha ve been bonded to a su bstrate overhang the substrate typically by about 1/8" (3 mm).

A wide assortment of router bits with different profiles are availab le a s accessories. Only use good quality bits.

Use only router bits

that h a v e shank diameters that match the installed collet. Using a router bit that has a

smaller shank could cause the bit to co me loose du ring operat ion a nd become a projectile.

Never operate

router bits at speeds that are higher than their maximum rated speed. Router bits

running faster than their rated speed can break and fly apart.

To prevent personal

injury, always remove the plug from power source before removing or in stal ling bits or accessories.

 Installing a Router Bit

1. Lay the router or motor on its side. The router can also be stood "on its head" for bit changes.

2. Press spindle lock to prev ent 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 coun ter-c lockw ise 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 loc k 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 prope r grip ping o f the router bit and minimize run-out, the shank of the router bit mu s t be inserted at least 5/8".

Cutter diameter

must be at least 1/4” smaller than opening for the bit and cutter.

To prevent damage

to tool, d o no t tighten collet without a bit.

NOTE: The bi t shank an d chuck

should be clean and free of dust, wood, residue, and grease before assembling.

 Removing the Router Bit

1. Press spindle lock to prev ent 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 selfextracting; 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 col let ch u ck cou nterclockwise until it is free of the shaft. To assure a firm grip, occasionally blow out t h e collet chuck w i t h 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 w o r n or damaged collet chucks immediately.

 Removing Motor from

PR101 Fixed Base

1. Turn the clamping knob to the unlocked position (A, Fig. 6).

2. Pull the motor away from base until it stops. (Do not press on the flap in the base whi le pulling the motor.) (C, Fig. 6).

3. Press and hold the motor release button. (B, Fig. 6).

Bosch routers are designed for speed, accuracy and con venience in pe rformi ng ca binet wor k, fluting, beading, c o v e - c u t t i n g , rounding ed ges, d ovetailing, etc. They w ill enable you to accomplish inlay work, decorative edges and many types of special routing.

 Setting the Depth of Cut

Adjust the depth-of-cut only when the motor is switched off.

1. Install desired router bit.

2. Place the router on the workpiece.

3. Turn the clamping knob to the top, unlocked position (A, Fig. 9).

4. Slowly lower the motor until the router bit touches the workpiece (

Fig. 9)

5. Note the reading on th e scale (above the motor release button) and add the desired depth-of-cut to this value to determine the target scale value.

Operating Instructions

 Installing the Motor into

PR101 Fixed Base

1. Open the clamping knob to the unlocked position (A, Fig. 6).

2. Align the slot on the motor with the pin on the base (Fig. 7)

To avoid pinchi n g

injury, keep all parts of your hands away from the top rim of the base and away f rom m etal section of the motor when pushing motor into base.

3. Push the motor into the base to the approximate desired position has been reached. Do not press on the flap in the base while installing the motor.

4. Turn the clamping knob to the bottom, locked position (E, Fig.

9). Always make sure the motor sits tightly in the base.

 Check Subbase Location

Cutter diameter

must be at least 1/4” smaller than opening for the bit and cutter.

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 three 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 RA11 51 centering device makes this easy.

3. Tighten the three screws that hold the subbase (Fig. 8).

When the subbase has been centered in this ma n n e r , a n y part of the subbase can be used as a guiding surface wit hout worrying about a difference in t h e cut line. See "Guiding The Router" on page 13.

Note: This subbase is not designed for use with template guides. The optional PR110 Attachment allows use of template guides with this palm router.

4. Check the depth-of-cut and make an additional fine adjustment if necessary.

Note: the depth of the motor and bit may shift very slightly when the clamping knob is turned to the locked position.

5. Make a trial cut to verify that the router is set to make the cut as desired.

 DEEP CUTS

For dee p cut s, ma ke se veral progressively deeper cuts by starting at one d epth and then m ake 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 b e 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

The electronic speed control feature allows motor speed to be matched to cutter size and material hardness for improved finish, extended bit life, and

igher 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 c h a r t i n d i c a t e s the relationship between settings and application, exact settings are determined by operator experience and preference. The bit manufacturer may also have a speed recommendation.

Never operate

router bits at speeds that are higher than their maximum rated speed. Router bits

running faster than their rated speed can break and fly apart.

Operating Instructions

 Feeding the Router

n 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 g u a r d s to provide a barrier between the finger pockets and the bit area (Fig 10).

Wh en us ing finger

pockets, 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.

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 11 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 t o make se v e r a l cuts of increasing depth.

If the router is hard to control, heats up , runs very slowl y 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 fr o m the wo r k before turning the switch off. Operating in this manner will prolong switch and motor life and will greatly increase the quality of your work.

 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 s

tall if improperly used or overloaded. Reduce the feed rate to prevent possible damage to the tool. Alwa y s be su r e the c o l let 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

he router can be guided through the wor k in a ny of several ways. T he method you use depends, of course, on the demands of the particular job and on convenience.

For r o u t i n g operations su c h as grooving or dadoing, it is often necessary to guide the tool in a line parallel to a straight edge. On e 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. 12).

 PR102 Edge Guide

The edge g u i d e is an o p t i o n a l accessory that will guide the router parallel to a straight edge (Fig. 14).

The edge guide is supplied in two parts held together with a bolt, wing nut and washer.

 ATTACHING THE EDGE GUIDE

1. Remove the subbase by unscrewing the three screws.

2. Position the adapter in the gap in the base.

3. Fasten the adapter using the two Philips screws (Fig. 13).

4. Reattach the subbase.

Note: See “Check S u b b a b s e Location” section on how to center the subbase.

5. Attach the edge guide to the adapter using the knurled screw with two washers (Fig. 14).

The guide features a sc a l e f o r 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 e d g e g u i d e 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.

Operating Instructions

2610052572_GKF125CE 9/18/18 12:11 PM Page 15

 USING SELF-PILOTED BITS

elf -pilote d bits have an int egral round tip or ball bearing which rides against the work surface above or below the cutter to control horizontal cutting depth (Fig. 15). 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 fr e e 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.

 PR110 Round Subbase and

Use of Template Guide Bushings with PR101 Fixed base

(Available as optional accessories)

Optional large round subbases are available separately and allow various template guide bushings to be used with the palm routers.

Template guide bushings are used to guide the router to repeatedly make consistent openings and inlays using various templates (also referred to as pa tterns and jigs). Temp lates for standa rd r outing applications are available commercially and templates for specialty applications are typically made by users for their specific needs.

The PR110 Round Subbase accepts threaded template guide adapters.

 PR110 ATTACHMENT ROUND

SUBBASE OF THREADED TEMPLATE GUIDE (Fig. 16)

1. Remove regular subbase.

2. Loosely attach round subbase using panhead screws that come with that accessory.

3. Attach the threaded template guide by putting the template guide through the bottom and attaching the ring from the top.

4. Center the template guide around the bit. ( The o ption al Bosch RA1151 Centering device can be used to ensure that the template guide is properly centered.)

5. Tighten the panhead screws to hold the template guide an d subbase in position.

 CREATING TEMPLATES

Template patterns can be made of plywood, hardboard, metal or even plastic. The design can be cut with a router, jigsaw, or other suitable cutting t o o l . Remember that the pattern will have to be made to compensate for the distance between the router bit and the template guide (the “offset”), as the final workpiece will differ in size from the template pattern by that amount, due to the bit position (Fig. 17).

 PR111 Plunge Base

(

Included with GKF125CEPK and sold

separately)

To install motor in plunge base:

1. Release the base clamp lever (Fig.

18).

2. Push the motor into the base as far as it will go.

3. Fasten the base clamp lever. If additi onal clamping force is

desired: using a 8 mm wrench, rotate cl amp nut clockwise SLIGHTLY (1/8 turn or less), then test clamp. Do not over-tighten.

To remove motor from plunge base:

1. Release the base clamp lever.

2. Press and hold the motor release button.

3. Pull motor up and out of base.

 DEPTH ADJUSTMENT

The plunge feature simplifies depth adjustments and will allow the cutting bit to easily and accurately enter the workpiece.

1. To lower, push plunge lock lever to the left, apply downward pressure until you reach desired depth, and release pressure on lever to lock (Fig. 19). The plunge lock lever is spring lo aded an d retur ns automatically to the locked position.

2. To raise the router, push plunge lock lev er to the left, release pressure on router and the router will automatically retract the bit from the workpiece. It is advisable to retract the bit whenever it is not engaged in work piece.

 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 ad justm ents c an 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. 20).

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 in dicator knob.

4. Finally, remove the jig.

 DEEP CUTS

For deeper c u t s , make s e v e r a l 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.

 FINE ADJUSTMENT

The PR111 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 kn o b represents 1/128”.

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 counter-clockwise 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 th e 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.

 Using the Router in the

Plunge Base
