3. General Safety Information

⚠ For your own protection and for the protection of your power tool, pay attention to all parts of the text that are marked with this symbol! WARNING ­ Read the operating instructions to reduce the risk of injury.
⚠ 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. Always include these documents when passing on your power tool.

4. Special Safety Instructions

4.1 Safety instructions for all operations

a) Wear ear protectors. Exposure to noise can cause hearing loss.
b) Use auxiliary handle(s), if supplied with the tool. Loss of control can cause personal injury.
c) Hold the power tool by insulated gripping surfaces, when performing an operation where the cutting accessory or fasteners may contact hidden wiring or its own cord. Cutting accessory contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.

4.2 Safety instructions when using long drill bits with rotary hammers

a) 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.
b) 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.

4.3 Further Safety instructions

Pull the plug out of the socket before making any adjustments, changing tools, carrying out maintenance or cleaning.
Always work with the additional handle correctly installed.
Always hold the machine with both hands on the intended handles, take a secure stance and concentrate on the work.
Wear personal protective equipment and always wear safety glasses. Protective equipment such as dust mask, non-skid safety shoes, protective gloves, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
Ensure that the place where you wish to work is free of power cables, gas lines or water pipes (e.g. check using a metal detector).
Work only with a correctly fitted tool. Pull on the tool to check that it is correctly seated. (It must be possible to move the tool a few centimetres in an axial direction.)
When working above ground level, ensure that the area below you is clear.
Never touch the tool or parts near the tool directly after work because they may be extremely hot and can cause burns to the skin,
Always position the power cable so that it leads away from the back of the machine.

A damaged or cracked additional handle must be replaced. Never operate a machine with a defective additional handle.

Secure the workpiece to prevent slipping or rotation (e.g. by securing with screw clamps).
Reducing dust exposure:
⚠ WARNING – 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 chemically treated 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.
This also applies to dust from other materials such as some timber types (like oak or beech dust), metals, asbestos. Other known diseases are e.g. allergic reactions, respiratory diseases. Do not let dust enter the body.
Observe the relevant guidelines and national regulations for your material, staff, application and place of application (e.g. occupational health and safety regulations, disposal).
Collect the particles generated at the source, avoid deposits in the surrounding area.
Use suitable accessories for special work. In this way, fewer particles enter the environment in an uncontrolled manner.
Use a suitable extraction unit.
Reduce dust exposure with the following measures: – do not direct the escaping particles and the
exhaust air stream towards yourself or nearby persons or towards dust deposits, – use an extraction unit and/or air purifiers, – ensure good ventilation of the workplace and keep it clean using a vacuum cleaner. Sweeping or blowing stirs up dust. – Vacuum or wash protective clothing. Do not blow, beat or brush protective gear.

6. Initial Operation

⚠ Before commissioning, check that the rated mains voltage and mains frequency stated on the type plate match your power supply.

⚠ Always install a universal current sensitive ground fault circuit interrupter (type B RCD) with a maximum trip current of 30 mA upstream.

Usescetioonnlyofe1x.t5enmsmio2n. cables with a minimum Extension cables must cross correspond to the power consumption of the machine (cf Technical Specifications). If a cable roller is used, always roll up the cable completely.

6.1 Assembly of the bow handle or additional handle

⚠ For safety reasons, always use the bow handle (2) or additional handle (3) supplied. MHEV…:
Release the clamping ring by turning the clamping knob (1) anticlockwise. Adjust the bow handle (2) to the required position and angle. Tighten the clamping knob firmly. KHEV…:
Open the clamping ring by turning the additional handle (3) anticlockwise. Secure the additional handle at the required angle. Tighten the additional handle.

7. Use

7.1 Depth Stop Setting

(Only for KHEV 5-40 BL)
Release the wing (4) screw. Set the depth stop (5) to the required drilling depth. Retighten the wing screw (4).

7.2 Positioning, removing tool

⚠ Before inserting, clean tool shank and apply supplied special grease (accessories: Order no. 6.31800)! Use only SDS-max tools. Positioning tool:
Turn tool and insert until it engages. The tool is automatically locked.
⚠ Pull on the tool to check that it is correctly seated. (It must be possible to move the tool a few centimetres in an axial direction.)
Remove the tool: Pull the tool lock (6) backwards in direction indicated by arrow (a) and remove tool (b).

7.3 Setting operating mode and chisel position

⚠ Avoid levering with the machine when a chisel is fitted.
⚠ Do not activate the switch button (7) until the motor has completely stopped.
Turn the switch button (7) to select the desired operating mode.
Impact drilling (only for KHEV…)
Chiselling
Setting which enables the chisel to be rotated to the desired position. Setting the position of the chisel: The chisel can be locked in different positions.
– Insert the chisel.
– Turn the knob (7) to the interim position .
– Turn the chisel to the required position.
– Turn the switch button (7) to position .
– Turn the chisel until it engages. When a chisel is fitted, only operate the machine in the chiselling operating mode .

7.4 Setting impact force

Press the button (14) to change the impact force (and the speed) (but not while the motor is running). Button (14) illuminated: reduced impact force, reduced speed (approx. 70%) Button (14) not illuminated: maximum impact force, high speed (100%) The correct setting is found by trial and error. Example: if work is being completed on soft, brittle material or if you want to keep breakage to a low level, work at “reduced impact force”. Use the “maximum impact force” setting for working with harder materials.

7.5 Switching on and off Torque setting:

Press the trigger switch (9) to switch on the machine.
To switch off release the trigger switch (9).
Continuous operation (only in chiselling mode ): The machine can be switched to continuous operation (only in chiselling mode ) by pressing the (10) button. ( (10) button illuminated.) To switch off, press the (10) button once again. ( (10) button not illuminated.)
In continuous operation, the machine continues running if it is forced out of your hands. Therefore, always hold the machine with both hands using the handles provided, stand securely and concentrate.

7.6 Metabo VibraTech (MVT)

For reduced vibrations and less stress on the hands.
Always apply a moderate amount of pressure to the handle when pushing down the machine and do not force. Vibrations are reduced most effectively at the central position (8).

8. Cleaning, Maintenance

The power tool should be cleaned regularly, often and thoroughly through all air vents using a vacuum cleaner or by blowing in dry air. Prior to this operation, separate the power tool from the power source and wear protective glasses and dust mask.
