2. 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 and instructions. Failure to follow all safety warnings and instructions may result in electric shock, fire and/or serious injury.
   Keep all safety instructions and information for future reference.
   Always include these documents when passing on your power tool.

3. Special Safety Instructions
   Wear ear protectors. Exposure to noise can cause hearing loss. Use auxiliary handle(s), if supplied with the tool. Loss of control can cause personal injury. Hold power tools by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring or its own cord. Contact with a live wire will make exposed metal parts of the tool live and shock the operator.
   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. Always wear protective goggles, gloves, a dust mask, and sturdy shoes when working with this tool.
   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 centimeters 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, and asbestos. Other known diseases are e.g. allergic reactions and 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, and 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.

Initial Operation

Before commissioning, check that the rated mains voltage and mains frequency stated on the type plate match your power supply.
Always install an RCD with a maximum trip current of 30 mA upstream.
Use only extension cables with a minimum crosssection of 1.5 mm 2
. Extension cables must 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.
THE…:
Open the clamping ring by turning the additional handle (3) anticlockwise. Secure the additional handle at the required angle. Tighten the additional handle.

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 the tool shank and apply supplied special grease (accessories: Order no. 6.31800)! Use only SDS-max tools.
Positioning tool:
Turn the tool and insert it 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) backward in the 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…)
Chiseling
N The setting 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 N
– 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 chiseling 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. For 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 chiseling mode ):
