Safety instructions

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.
Keep all safety instructions and information 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 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 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 and clothing 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.
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 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.
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

Always charge the batteries only in chargers recommended by the manufacturer.
Chargers designed for a specific type of battery may pose a fire hazard when used together with other battery types.
Use only the batteries provided for this purpose in the power tools. Using other
batteries may cause injuries and pose a fire hazard.
When not in use, keep batteries away from paper clips, coins, nails, screws or other small metal objects that could bridge the contacts.
Short circuits between battery contacts can cause burns or fires.
Fluid may escape if batteries are used inappropriately. Avoid all contact with this fluid. In the event of accidental skin contact, rinse the affected area thoroughly. If the fluid enters your eyes, seek immediate medical assistance. Escaping battery fluid can cause skin irritation or burns.
Do not use damaged or modified batteries. Damaged or modified batteries may behave unpredictably and lead to fire, explosion or risk of injury.
Do not expose the battery pack to fire or excessive temperatures. Fire or temperatures above 130 °C can cause an explosion.
Follow all instructions on charging and never charge the battery or the cordless tool outside the temperature range indicated in the operating instructions. Incorrect charging or charging outside the permitted temperature range may destroy the battery and increase the risk of fire.

Service

Have your power tool serviced by a qualified technician using only original replacement parts. This will ensure that the safety of the power tool is maintained.
Never service damaged batteries. Any servicing of batteries should only be carried out by the manufacturer or authorized customer service points.

Hammer and Drill Safety Warnings

Safety instructions for all operations

Wear ear protectors. Exposure to noise can cause hearing loss.
Brace the tool properly before use. This tool produces a high output torque and without properly bracing the tool during operation, loss of control may occur resulting in personal injury.
Hold the power tool by insulated gripping surfaces, when performing an operation where the cutting accessory or fasteners may contact hidden wiring. Cut-ting accessory or fasteners contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.

Safety instructions when using long drill bits

Never operate at higher speed than the maximum speed rating of the drill bit. At higher speeds, the bit is likely to bend if allowed to rotate freely without contacting the workpiece, resulting in personal injury.
Always start drilling at low speed and with the bit tip in contact with the workpiece. At higher speeds, the bit is likely to bend if allowed to rotate freely without contacting the workpiece, resulting in personal injury.
Apply pressure only in direct line with the bit and do not apply excessive pressure. Bits can bend causing breakage or loss of control, resulting in personal injury.

Additional safety information

Use auxiliary handle(s), if supplied with the tool. Loss of control can cause personal injury.
Hold the power tool firmly with both hands and make sure you have a stable footing. The power tool can be more securely guided with both hands.
Switch the power tool off immediately if the application tool becomes blocked. Be prepared for high torque reactions which cause kickback. The application tool becomes blocked when it becomes jammed in the workpiece or when the power tool becomes over-loaded.
Secure the workpiece. A workpiece clamped with clamping devices or in a vice is held more secure than by hand.
Use suitable detectors to determine if there are hid-den 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 ex-plosion. Breaking water pipes causes property damage.
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, va-pours may be emitted. The battery can set alight or ex-plode. 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 with products from the manufacturer. 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.

Technical data determined using the battery that comes with the product.

Noise/Vibration Information

Noise emission values determined according to EN 60745-2-6.
Typically, the A-weighted noise level of the power tool is: Sound pressure level 85 dB(A); sound power level
96 dB(A). Uncertainty K = 3 dB.
Wear hearing protection!
Total vibration values ah (triax vector sum) and uncertainty K determined according to EN 60745-2-6, EN 62841-2-1:
Hammer drilling into concrete: ah=13 m/s2, K=3 m/s2,
Drilling into metal: ah=4 m/s2, K=1.5 m/s2,
Screwdriving: ah=2.5 m/s2, K=1.5 m/s2,
The vibration level and noise emission value given in these instructions have been measured in accordance with a standardised measuring procedure and may be used to com-pare power tools. They may also be used for a preliminary estimation of vibration and noise emissions.
The stated vibration level and noise emission value represent the main applications of the power tool. However, if the power tool is used for other applications, with different application tools or is poorly maintained, the vibration level and noise emission value may differ. This may significantly increase the vibration and noise emissions over the total working period.

To estimate vibration and noise emissions accurately, the times when the tool is switched off or when it is running but not actually being used should also be taken into account. This may significantly reduce vibration and noise emissions over the total working period.
Implement additional safety measures to protect the operator from the effects of vibration, such as servicing the power tool and application tools, keeping their hands warm, and organizing workflows correctly.

Assembly

Remove the battery from the power tool before carrying out work on the power tool (e.g. maintenance, changing tool, etc.). The battery should also be re-moved for transport and storage. There is risk of injury from unintentionally pressing the on/off switch.
Before any work on the tool (e.g. maintenance, tool change etc.) as well as during transport and storage, set the rotational direction switch to the middle position. There is risk of injury from unintentionally pressing the on/off switch.

Battery Charging (see figure A)

Use only the chargers listed in the technical data. Only these chargers are matched to the lithium-ion battery of your power tool.

Note: The battery is supplied partially charged. To ensure full battery capacity, fully charge the battery in the charger before using your power tool for the first time.
The lithium-ion battery can be charged at any time without reducing its service life. Interrupting the charging process does not damage the battery.
The lithium-ion battery is protected against deep discharge by the “Electronic Cell Protection (ECP)”. When the battery is discharged, the power tool is switched off by means of a protective circuit: The application tool no longer rotates.

Do not continue to press the On/Off switch after the power tool has automatically switched off. The battery can be damaged.
- To remove the battery (10), press the release button (18) and pull the battery to the rear and out of the power tool. Do not use force to do this.

Follow the instructions on correct disposal.

Selecting drill chucks and tools
An SDS quick application tool is required for hammer drilling.
To drill without impact in wood, metal, ceramic and plastic you can use a suitable SDS quick application tool, a hexagonal shank application tool or the keyless chuck with application tools that do not have SDS quick.
For screwdriving, only use screwdriver bits which have a ball catch (14) (DIN 3126-E6.3). Other screwdriver bits (13) can be inserted using a universal bit holder with ball catch (12).

You will find a selection of suitable application tools in the accessories overview at the end of these operating instruc-tions.

Changing the Keyless Chuck
You must use the keyless chuck (19) to work with application tools that do not have SDS-Quick (e.g. cylindrical shank drill bits).

Inserting the keyless chuck (see figure B)

Clean and lightly grease the insertion end of the shank.
Insert the keyless chuck (19) with the shank into the tool holder while turning it until it locks automatically.
Check that it is locked by pulling the keyless chuck. Removing the Keyless Chuck
Push the locking sleeve (3) back and remove the keyless chuck (19).

Changing the Tool

****The tool holder can also accommodate different application tools with a hexagonal shank with groove and SDS quick shank. The tool holder allows for simple and convenient tool-free changing of the application tool.

As a requirement of the system, the application tool can move freely. This causes a certain radial run-out at no-load, which has no effect on the accuracy of the drill hole, as the drill bit centers itself upon drilling.
The dust protection cap (2) largely prevents the penetration of drilling dust into the tool holder during operation. When inserting the tool, make sure that the dust protection cap (2) does not become damaged.

Replace a damaged dust protection cap immediately. It is recommended that you have use an after-sales service for this.

Inserting SDS-Quick application tools (see figure C)

Clean and lightly grease the insertion end of the application tool.
Insert the application tool into the tool holder while turning it until it locks automatically.
Check the latching by pulling the tool.

Removing SDS-Quick application tools (see figure D)

Push the locking sleeve (3) back and remove the application tool.

BOSCH-Uneo-Maxx-Cordless-Rotary-Hammer-3

Inserting application tools that do not have SDS-Quick (see figure E)
Note: Application tools that do not have SDS-Quick must not be used for hammer drilling. Hammer drilling will damage tools without SDS-Quick along with their chucks.

Insert the keyless chuck (19).
Hold the rear sleeve (21) of the keyless chuck (19) firmly and turn the front sleeve (20) anti-clockwise until the tool can be inserted. Insert the tool.
Hold the rear sleeve of the keyless chuck (19) and firmly tighten the front sleeve by hand in a clockwise direction until it stops clicking. This will automatically lock the drill chuck.
Check that it is seated securely by pulling the tool.
Note: If the tool holder was unscrewed all the way, a scraping sound may be heard while retightening the tool holder and it may not fully tighten.
In this case, turn the front sleeve (20) anti-clockwise by one turn. This will allow the tool holder to be fully tightened.
Turn the “Drilling/hammer drilling” selector switch (4) to the “drilling” position.

Removing application tools that do not have SDS-Quick (see figure F)
Hold the rear sleeve (21) of the keyless chuck firmly and turn the front sleeve (20) of the keyless chuck anti-clock-wise until the application tool can be removed.

Dust/Chip Extraction
Dust from materials such as lead-containing coatings, some wood types, minerals and metal can be harmful to one’s health. Touching or breathing-in the dust can cause allergic reactions and/or lead to respiratory infections of the user or bystanders.
Certain dust, such as oak or beech dust, is considered carcinogenic, especially in connection with wood-treatment additives (chromate, wood preservative). Materials containing asbestos may only be worked by specialists.

Provide for good ventilation of the working place.
It is recommended to wear a P2 filter-class respirator. Observe the relevant regulations in your country for the materials to be worked.

Avoid dust accumulation at the workplace. Dust can easily ignite.

Operation

Start-up

Inserting the Battery

Use only original Bosch lithium-ion batteries with the voltage stated on the type plate of your power tool. Using other batteries can lead to injuries and pose a fire hazard.
- Set the rotational direction switch (7) to the middle position to avoid unintentionally switching it on.
- Insert the charged battery (10) into the handle until you feel it engage and it is flush with the handle.

Setting the Operating Mode
Use the “Drilling/hammer drilling” selector switch (4) to select the power tool’s operating mode.

Note: Only change the operating mode when the power tool is switched off. Otherwise, the power tool may become dam-aged.

To change the operating mode, slide the “Drilling/hammer drilling” selector switch (4) to the required position.

Position for hammer drilling into concrete or stone
Position for drilling without impact in wood, metal, ceramic and plastic and for screw-driving

Setting the rotational direction (see figure G)

Only operate the rotational direction switch (7) when the power tool is not in use.

The rotational direction switch (7) is used to change the rotational direction of the power tool. However, this is not possible while the on/off switch (8) is being pressed.

Right rotation: To drill and to drive in screws, press the rotational direction switch (7) through to the left stop.
The rotational direction indicator for right rotation (5) lights up when the on/off switch (8) is pressed and the motor is running.
Left rotation: To loosen and unscrew screws and nuts, press the rotational direction switch (7) through to the right stop.
The rotational direction indicator for left rotation (6) lights up when the on/off switch (8) is pressed and the motor is running.

BOSCH-Uneo-Maxx-Cordless-Rotary-Hammer-05

Switching On/Off

To start the power tool, press and hold the on/off switch (8).
The lamp (11) lights up when the on/off switch (8) is lightly or fully pressed, meaning that the work area is illuminated in poor lighting conditions.
For low temperatures, the power tool reaches the full hammer/ impact capacity only after a certain time.
To switch off the power tool, release the on/off switch (8).

Adjusting the Speed/Impact Rate

Adjust the speed/impact rate of the power tool when it is on by pressing in the on/off switch (8) to varying extents.
Applying light pressure to the on/off switch (8) results in a low rotational speed/impact rate. Applying increasing pressure to the switch increases the speed/impact rate.

Run-out brake
Upon releasing the on/off switch (8), the drill chuck is slowed down, which prevents the application tool from continuing to rotate.
When driving in screws, you should therefore only release the on/off switch (8) once the screw has been inserted flush into the workpiece. This way, the head of screw will not penetrate the workpiece.

Battery Charge Indicator
When the on/off switch (8) is pressed in halfway or completely, the battery charge indicator (9) indicates the battery’s state of charge for several seconds. The indicator consists of three green LEDs.

BOSCH-Uneo-Maxx-Cordless-Rotary-Hammer-12

Temperature-dependent overload protection
In normal conditions of use, the power tool cannot be over-loaded. If the power tool is overloaded or not kept within the permitted battery temperature range, the power output is reduced or the power tool is switched off. The power tool will not run at full power output again until the permitted bat- tery temperature has been reached.
The three LEDs in the battery charge indicator (9) and the lamp (11) flash quickly when the temperature of the battery is outside the operating temperature range of -20 to +50 °C and/or the overload protection has been triggered.

Protection against deep discharge
The lithium-ion battery is protected against deep discharge by the Electronic Cell Protection (ECP). When the battery is discharged, the power tool is switched off by means of a protective circuit: The application tool no longer rotates.

Practical Advice

Only apply the power tool to the screw/nut when the tool is switched off. Rotating tool inserts can slip off.

Maintenance and Service

Maintenance and Cleaning

Remove the battery from the power tool before carry-ing out work on the power tool (e.g. maintenance, changing tool, etc.). The battery should also be re-moved for transport and storage. There is risk of injury from unintentionally pressing the on/off switch.
