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 – Reading the operating instructions will 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.
Pass on your power tool only together with these documents.
Special Safety Instructions
- Wear ear protectors. Exposure to noise can cause hearing loss.
- Use the additional handle supplied with the tool. Loss of control can cause personal injury.
- Hold the power tool by the insulated gripping surfaces when performing an operation where the cutting accessory may contact hidden wiring or its own cord. A cutting accessory contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.
- Always work with the additional handle correctly installed.
- Always hold the machine with both hands at the intended handles, take a secure stance and concentrate on the work.
- Always wear protective goggles, gloves, and sturdy shoes when working with this tool.
- Ensure that the spot where you wish to work is free of power cables, gas lines or water pipes (e.g. using a metal detector).
- If the safety coupling responds, switch off the machine immediately.
- Do not touch the rotating tool!
- Secure the workpiece to prevent slipping or rotation (e.g. by securing with screw clamps).
- Remove chips and similar material only with the machine at a standstill.
- Caution must be exercised when driving screws into hard materials (driving screws with metric or imperial threads into steel)! The screw head may break or a high reverse torque may build up on the handle.
- Pull the plug out of the socket before making any adjustments, changing tools, carrying out maintenance or cleaning.
- Avoid inadvertent starts by always unlocking the switch when the plug is removed from the mains socket or whenever the power fails.
- A damaged or cracked additional handle must be replaced. Never operate a machine with a defective additional handle.
- Safety clutch: f the tool jams or catches, the power supply to the motor is restricted. Due to the strong force which can arise, always hold the machine with both hands using the handles provided, stand securely and concentrate.
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 at yourself or nearby persons or on dust deposits,
- use an extraction unit and/or air purifiers,
- ensure good ventilation of the workplace and keep clean using a vacuum cleaner. Sweeping or blowing stirs up dust.
- Vacuum or wash the protective clothing. Do not blow, beat or brush.

Assembly of the additional handle
For safety reasons, always use the additional handle supplied.
Open the clamping ring by turning the side handle (7) counter-clockwise. Push the additional handle onto the collar of the machine. Insert the depth stop (8). Securely tighten the additional handle at the angle required for the application.
Use
Depth Stop Setting
Loosen the additional handle (7). Set the depth stop (8) to the desired
drilling depth and retighten additional handle (7).
Switching On and Off
Press the trigger switch (15) to switch on the machine.
The speed can be changed using the trigger switch.
UHEV 2860-2 Quick:
The electronic soft start means that the machine accelerates continuously up
to the pre-selected speed.
For continuous operation, the trigger button can be locked using the lock
button (14) . Press the trigger switch again to stop the machine.
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.
Select speed (only for UHE…)
Select the optimal speed at the thumbwheel (12) depending on the application.
Operating mode selection
Press the lock (9) and turn the thumbwheel (10).
- When a chisel is fitted, only operate the machine in the chiselling operating mode
- Avoid levering with the machine when a chisel is fitted.
Selection of direction of rotation
Only activate the rotation selector switch (13) when the motor has
completely stopped.
Select direction of rotation:
R = clockwise rotation (for drilling, hammer
drilling, chiselling, drive in screws)
L=anti-clockwise rotation (for the removal of screws)
Drill chuck change
Ensure a clean spindle (6) when changing the chuck. Apply a light coating of
grease to the spindle. (Special grease: Order No.: 6.31800)
