General Power Tool Safety Warnings
WARNING
Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed below 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 (cord-less) 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 un-avoidable, use a residual current device (RCD) protected supply. Use of an RCD 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 a 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 energising 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 jewellery. Keep your hair and clothing away from moving parts. Loose clothes, jewellery 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.

• Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.

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.

• Disconnect the plug from the power source and/or remove the battery pack, if detachable, 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 and accessories. Check for mis-alignment 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.

• Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.

Battery tool use and care

• Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.

• Use power tools only with specifically 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 metal objects, that can 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.

• Do not use a battery pack or tool that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behaviour resulting in fire, explosion or risk of injury.

• Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or temperature above 130 °C may cause explosion.

• Follow all charging instructions and do not charge the battery pack or tool outside the temperature range specified in the instructions. Charging improperly or at temperatures outside the specified range may damage the battery and increase the risk of fire.

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.
• Never service damaged battery packs. Service of battery packs should only be performed by the manufacturer or authorized service providers.

Safety instructions for edge routers

• 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
  un-stable and may lead to loss of control.

• The permitted speed of the cutting bit must be at least equal to the maximum speed marked on the power tool. If cutting bits run faster than their rated speed, they may break and fly off.

• Routers and other accessories must be able to fit exactly in the tool holder (collet) of your power tool. Application tools that do not fit exactly in the tool holder of the power tool will turn unevenly, vibrate heavily and may cause a loss of control.

• Only bring the power tool into contact with the work-piece when switched on. Otherwise there is danger of kickback if the cutting tool jams in the workpiece.

• Never rout over metal objects, nails or screws. The router could become damaged and cause increased vibration.

• Use suitable detectors to determine if there are hidden supply lines or contact the local utility company for assistance. Contact with electric cables can cause fire and electric shock. Damaging gas lines can lead to explosion. Breaking water pipes causes property damage.

• Do not use blunt or damaged routers. Blunt or damaged routers cause increased friction, create imbalances and may become jammed.

• Always wait until the power tool has come to a complete stop before placing it down. The application tool can jam and cause you to lose control of the power tool.

• In case of damage and improper use of the battery, vapours may be emitted. The battery can set alight or explode. Ensure the area is well ventilated and seek medical attention should you experience any adverse effects. The vapours may irritate the respiratory system.

• Do not open the battery. There is a risk of short-circuiting.

• The battery can be damaged by pointed objects such as nails or screwdrivers or by force applied externally. An internal short circuit may occur, causing the battery to burn, smoke, explode or overheat.

• Only use the battery in the manufacturer’s products. This is the only way in which you can protect the battery against dangerous overload.

Protect the battery against heat, e.g. against continuous intense sunlight, fire, dirt, water and moisture. There is a risk of explosion and short- circuiting.

Removing the routing base (see figure A)

Before fitting a router bit, you must first separate the routing base (2) from the drive unit (1).
Open the wing bolt (12) on the routing base (2).
Pull the drive unit out in an upward direction.

Changing the Collet (see figure B)

Depending on the router bit used, you may have to change the collet with the cap nut (6) before fitting the router bit. If the right collet for your router bit is already installed, follow the work steps in the following section.
The collet must sit in the cap nut with a small amount of play. The collet with the cap nut (6) must be easy to fit. If the cap nut or collet is damaged, replace it immediately.
Press and hold the spindle lock button (8). If necessary, turn the motor spindle manually until it is locked in place. Unscrew the cap nut (6) anticlockwise with the open-ended spanner (21).
Release the spindle lock button.
Note: Alternative possibility for replacing collet (without pressing the spindle lock button (8)): Place two wrenches on the shaft using a dihedron, in order to loosen or tighten the cap nut (6).
If required, clean all the parts you want to fit with a soft brush or by blowing them clean with compressed air before assembling them.
Place the new cap nut on the tool holder (20).
Loosely tighten the cap nut.

• Do not, under any circumstances, tighten the collet with the tightening nut until a router bit has been fitted. The collet may otherwise become damaged.

Fitting the router bit (see figure C1 – C2)

Router bits are available in a wide variety of designs and qualities depending on the intended application.
Router bits made of high-performance high-speed steel (HSS) are suited to machining soft materials such as soft-wood and plastic.
Router bits with carbide tips (HM) are especially suitable for hard and abrasive materials such as hardwood and aluminium.
Original router bits from the extensive range of Bosch accessories are available from your specialist dealer.
Only use undamaged and clean router bits.

Installing the Routing Base (see figure A)
To start routing, the routing base (2) must be fitted back onto the drive unit (1).
Open the wing bolt (12) on the routing base (2).
Slide the drive unit (1) into the routing base (2).
Close the wing bolt (12) on the routing base (2).
Note: The wing bolt (12) and the knurled screw (3) can be exchanged with each other.

• After assembly, always check that the drive unit is firmly seated in the routing base.

Dust/Chip Extraction

The dust from materials such as lead paint, some types of wood, minerals and metal can be harmful to human health. Touching or breathing in this dust can trigger allergic reactions and/or cause respiratory illnesses in the user or in people in the near vicinity.
Certain dusts, such as oak or beech dust, are classified as carcinogenic, especially in conjunction with wood treatment additives (chromate, wood preservative). Materials containing asbestos may only be machined by specialists.

• Use a dust extraction system that is suitable for the material wherever possible.
• Provide good ventilation at the workplace.
• It is advisable to wear a P2 filter class breathing mask. The regulations on the material being machined that apply in the country of use must be observed.
• Avoid dust accumulation at the workplace. Dust can easily ignite.

Fitting the dust extraction adapter
To ensure optimum extraction, the dust extraction adapter (29) must be cleaned regularly.

Connecting the Dust Extraction System (see figure D)

Insert the adapter for dust extraction (11) into the power tool from the front. It audibly engages. To remove, grasp the side of the adapter (11) and pull it off forwards.
Insert an extraction hose (dia. 35 mm) (30) (accessory) or a dust extraction adapter (29) (accessory). Connect the dust extraction hose (30) to a dust extractor (accessory).
The dust extractor must be suitable for the material being worked.
When extracting dry dust or dust that is especially detri-mental to health or carcinogenic, use a special dust extractor.

Operation

Setting the routing depth

• The routing depth must only be set while the power tool is switched off.
• Place the power tool with a fitted router bit onto the work-piece you want to machine.
• Reopen the wing bolt (12) on the routing base (2) in order to set the required routing depth based on the scale for setting routing depth (19) either by hand or with the knurled screw (3).
• Close the wing bolt (12) on the routing base (2).
• Check the routing depth you have set by carrying out a practical test and correct it if required.

Starting Operation
Preselecting the speed
You can preselect the required speed using the speed preselection thumbwheel (16), even during operation.

The values displayed in the following table are guidelines. The required speed depends on the material and the working conditions; it can be ascertained through practical tests.

After working for a long time at a low speed, you should let the power tool rotate at no load for some time at maximum speed to cool down.

Switching on/off
To switch on the power tool, set the on/off switch (13) to I. To switch off the power tool, set the on/off switch (13) to 0.

Constant electronic control
The Constant Electronic keeps the speed at no load and under load virtually consistent, guaranteeing uniform performance.

Working Advice

• Protect router bits against shock and impact.
• Before carrying out any work on the power tool (e.g. maintenance, tool change etc.), remove the battery from the power tool. There is risk of injury from
  unintentionally pressing the on/off switch.

Routing direction and routing process (see figure E)

• Routing must always be carried out with the work-piece being moved against the direction in which the router bit (5) is turning (up cut). If the workpiece is moved in the same direction as the router bit is turning (down cut), the power tool may be pulled out of your hands.
• Only use the power tool when the routing base (2) is fitted. Losing control of the power tool can cause injuries.

Note: Be aware that the router bit (5) always protrudes slightly from the base plate (10). Do not damage the template or the workpiece.
Set the routing depth you want.
Switch on the power tool and guide it to the point you want to machine.
Switch off the power tool after routing.

• Do not put the power tool down before the router bit has come to a complete stop. Application tools that are still running can cause injuries.

Routing with guide bushing (see figure F1 – F3)

Using the guide bushing (22), you can transfer contours from templates or patterns to the workpiece.
Select the guide bushing that is suitable for the thickness of the template or pattern. Due to the protruding height of the guide bushing, the template must have a minimum thickness of 8 mm (see figure F1).

• Select a router bit with a diameter that is smaller than the interior diameter of the guide bushing.

Unscrew the four cylinder screws on the underside of the guide plate (9) and remove the guide plate.
Insert the guide bushing (22) into the guide plate (see figure F2).
Loosely screw the guide plate back onto the base plate (10). It must still be possible to move the guide plate freely.
To ensure that the distance between the centre of the router bit and the edge of the guide bushing is uniform, the guide bushing and guide plate must (if necessary) be centrally aligned with each other.

• Align the guide plate such that the router bit and guide bushing are centred on the opening in the guide plate (see figure F3).
• Hold the guide plate in this position and firmly tighten the fastening screw.

To rout with the guide bushing (22), proceed as follows:

• Place the power tool with the guide bushing (22) onto the template.
• Guide the power tool with the protruding guide bushing along the template using lateral pressure.

Edge or profile routing (see figure G)

For edge and profile routing without a parallel guide, the router bit must be fitted with a pilot pin or a ball bearing.
While it is switched on, guide the power tool towards the workpiece from the side until the pilot pin or the ball bearing of the router bit is touching the side of the workpiece edge that you want to machine.
Guide the power tool along the workpiece edge. Pay attention that the router is positioned perpendicularly. Too much pressure can damage the edge of the workpiece.

Routing with a parallel guide (see figure H)

You can fit a parallel guide (23) for when cutting parallel to an edge.
Fit the parallel guide (23) to the routing base (2) using the knurled screw (4).
Set the required stop depth using the wing bolt on the parallel guide (24).
While it is switched on, guide the power tool along the work-piece edge with a uniform feed and while applying lateral pressure to the parallel guide.

Routing with a pilot (see figure I)

The pilot (25) helps when routing edges with router bits without a pilot pin or ball bearing.
Fit the pilot to the routing base (2) using the nut (4). Guide the power tool along the workpiece edge with a uniform feed.
Lateral clearance: To change the amount of material being removed, you can adjust the lateral clearance between the workpiece and the guide roller (28) on the pilot (25). Loosen the wing bolt (26), set the lateral clearance you want by turning the wing bolt (27), then retighten the wing bolt (26).
Height: Set the vertical alignment of the pilot according to the router bit you are using and the thickness of the work-piece you want to machine.
Loosen the nut (4) on the pilot, slide the pilot into the desired position and retighten the bolt.

Maintenance and Service

Maintenance and Cleaning

• Before carrying out any work on the power tool (e.g. maintenance, tool change etc.), remove the battery from the power tool. There is risk of injury from
  unintentionally pressing the on/off switch.
