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 adapt e r p lugs wi t h e arthed (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 c o mmon sen se w hen operati ng 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 the off- posi tion be fore connecting to power source and / or battery pa ck, pic king up or car ryin g t he tool.

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.

Safety Rules for Routers

Use c lamp s o r a noth er prac tica l w ay 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.

arrying 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 n trol of the pow er t o ol i n une x p ected 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 for ce the pow e r too l . 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 n n o t be control l e d with the switch 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

arts and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use.

Ma n y a c c i dents are caused by poo r l y 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.

Battery tool use and care

Recharge only with the charger specified by th e ma nufa ctur er. A c harg er t hat is

suitable for one type of battery pack may create a risk of fire when used with another battery pack.

Use po wer tools only with sp ecificall y designated battery packs. Use of any other

battery packs may create a risk of injury and fire.

When battery pack is not in use, keep it away from other metal objects like paper clips, coins, keys, nails, screws, or other small m e t a l objects that c a n make a connection from one terminal to another.

Shorting the battery terminals together may cause burns or a fire.

Under abusive conditions, liquid may be ejected from the battery, avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the

battery may cause irritation or burns.

Service

Have your power tool serviced by a qualified re p a i r pe r s o n us i n g onl y ident i c a l replacement parts. This will ensure that the

safety of the power tool is maintained.

160992A400_GKF12V-25 10/9/17 2:58 PM Page 3

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 la y wo r k p iece on to p of hard surfaces, li k e concr e t e , stone, et c . . .

Protruding cutting bit may cause tool to jump.

Always wear safety goggles and dust mask. Us e only in w e l l ventilated a r e a . Usi n g

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

After c h a n g i n g t he bits or m a k i n g a n y adjustments, make sure the collet nut and any other adjustment devices are securely tigh t e n e d . Loose adjustment d e v i c e can

unexpectedly shift, ca using loss of control, loose rotating compo nents wi ll be violently thrown.

Never start the tool when the bit is engaged in the material. The bit cutting edge may grab

the m ater ial cau sing los s o f co ntro l of th e 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 to o l fr o m t h e t o p , the bit rotates clockwise. Feed direction of cutting must be counter-clockwise. NOTE: inside and outside

uts 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.

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

Use this tool with Bosch recommended batteries only. Use of any other battery pack

may create a risk of injury and fire.

Use only router bits with rated speed at least equal to the maximum no load speed marked on the router. Router bits running

faster than their rated speed can break and fly apart.

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 su pport 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 th e tool sinc e inter nal wire s may be misplaced or pinched or safety guard return

sp ring s may be improp erly mount ed.

Certain cleaning agents such as gasoline, carbon tetrachloride, am mon ia, etc. ma y 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 ca use ca ncer , bi r t h de f e cts or ot h er 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.

Yo u r risk fr o m these e x p o sures v a r i es, depending on how often you do this type of work. To re duc e y our exposu re 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 routing applications that use 1/4" sh a nk bi t s. Th e se in c lude woo d workin g applications such as edge forming, grooving, and sign making. This router is also ideal for trimming la minat es, phenolics, and oth er ma t erial s that h a ve bee n bonde d 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.

Use only router bits with

rated speed at least equal to the maximum no load speed marked on the router. Router bits running faster than their

rated speed can break and fly apart. NOTE: The bit shank and chuck should be

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

To pre v ent p erson a l

FEEDING THE ROUTER

In addition to the main gripping area 13, the base has Bosch -excl usive finger suppo rt pockets 20 to provide additional stability for the router (Fig. 8).

Always hold the router

with b oth hands. Keep

fingers away from router bits and cutters.

Hands contacting with rotating router bit can cause serious personal injury.

Always place both finger

po c kets o ver the workpiece and always hold the router in a way that allows you to see your fingers and thumb.

Ne ver hold the too l in

ot h er way s , such a s those shown in figures 9 and 10.

FIG. 9

160992A400_GKF12V-25 10/9/17 2:58 PM Page 11

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. 12). When using

these bits, n either the roller g uide or the straight gu ide is requi red . W hen gu idi ng 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 oth er re sidue. Rou ter b it be aring s are sealed and permanently lubricated, and should be replaced when they no longer turn freely to avoid damaging the work surface.

The following maximum workpiece dimensions apply for edge and profile routing operations:

Material Radius Chamfer

Hardwood 3/8” / 10mm 1/4” / 6mm

Softwood 1/2” / 12mm 3/8” / 10mm

MDF sheets 1/2” / 12mm 3/8” / 10mm

Plastic 1/2” / 12mm 3/8” / 10mm

Plywood sheets 3/8” / 10mm 1/4” / 6mm

As seen from the top of the router, the bit 17 turns clockwise (23) and the bit’s cutting edges are positioned to best cut into the workpiece

21. Therefore, the most efficient cut is made by feeding (22) 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 to make several cuts of increasing depth.

If the router is hard to control, heats up, runs ve r y slo wly or leaves an impe rfect 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.

. 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 workpiece 21 when turning the switch on or off. Contact the workpiece with the router after the router has reached full speed, and remove it from the workpiece 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 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 cu ttin g l engt h ne cess ary to prod uce the desired cut. This will minimize router bit run-out and chatter.

It may be necessary to make the cut in more than o ne pass with prog ressi vely 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.
