General Safety Instructions
WARNING – Reading the operating instructions will 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. Pass on your
electrical tool only together with these documents.
Special Safety Instructions
Safety instructions for all operations
- Wear ear protectors when impact drilling. Exposure to noise can cause hearing loss.
- Use the auxiliary handle. Loss of control can cause personal injury.
- Brace the tool properly before use. This tool produces a high output torque and without prperly 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 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.
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 and loss of control, resulting in personal injury. Pull the plug out of the plug socket before any adjustments or servicing are performed.
- Avoid inadvertent starts by always unlocking the switch when the plug is removed from the mains socket or in case of a power cut.
- 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).
- Smaller workpieces must be secured such that they are not carried along with the drill bit when drilling (e.g. by clamping in a vice or on a work bench with screw clamps).
- Keep hands away from the rotating tool! Remove chips and similar material only with the machine at standstill.
- Metabo S-automatic safety clutch. When the safety clutch responds, switch off the machine immedi-ately! If 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.
- The Metabo S-automatic safety clutch must not be used for torque control.
- Caution with hard screwdriving (driving of screws with either a metric or an imperial thread into steel)! The head of the screw may rip off or high restoring torques may be incurred at the handle.
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.

Initial Operation
- Before plugging in the device, check to see that the rated mains voltage and mains frequency, as specified on the rating label, match your power supply.
- Always install an RCD with a maximum trip current of 30 mA upstream.
- To guarantee secure purchase of the chuck: After initial drilling (clockwise), use a screw-driver to firmly tighten the safety screw inside the drill chuck (if available/depending on the model). THE SAFETY SCREW HAS A LEFT-HANDED THREAD!
Fitting the additional handle (2) Fig. B
For safety reasons, always use the additional handle supplied.
Tighten the additional handle firmly by turning it.

Selecting gear Fig. F
Change thumbwheel (1) only when the machine is in the process of running down
(briefly switch it on and off).
Setting impulse function Fig. G
impulse function switched on constantly (to facilitate tightening and
releasing of screws that are tight even when the screw heads are damaged. To
enable clean drilling without
centre punching in tiles, aluminium or other materials).
Preselecting rotational speed Fig. H
See the table for recommended rotational speeds for drilling.
Switching On and Off
Switching on, rotational speed Fig. A: Press the trigger (13).

If the chuck is very tightly closed: Firmly grip the chuck with an open-end
spanner at the chuck head and firmly turn the sleeve in the direction of the
arrow -1.
Clamping the tool
- Insert the tool -2- as far as possible.
- Using one hand, hold the retainer ring securely (depending on fittings).
- Turn sleeve in direction -3- until the noticeable mechanical resistance has been overcome.
- Caution! The tool is not yet fully tightened!Keep turning the sleeve (it must “click” when turning) until it cannot be turned any further – only now is the tool safely clamped.
With a soft tool shank, retightening may be required after a short period of operation.
Tool change, geared chuck (4) Fig. K
Unscrew the chuck (when driving screws without the chuck or for use with attach-ments) Fig. L, M, or N
Note for Fig. M, N: Release by tapping lightly with a rubber hammer, as shown,
and unscrew.
Note: If a bit clamping bush (order no. 6.31281) is attached, the screwdriver
bit inserted in the hexagon socket of the spindle is held in place.
Cleaning, Maintenance
Keyless chuck cleaning:
After prolonged use hold the chuck vertically, with the opening facing down,
and fully open and close it several times. The dust collected falls from the
opening. The application of cleaning spray to the jaws and jaw openings at
regular intervals is recom-mended.
Troubleshooting
Electronic signal display (10):
Rapid flashing – restart protection (SBEV 1300-2, SBEV 1300-2 S, SBEV 1100-2
S, SBE 1000-2)
When power is restored after a power failure, the machine – which is still
switched on – will not start for safety reasons. Switch machine on and off
again.
Slow flashing – carbon brushes worn
(SBEV 1300-2, SBEV 1300-2 S, SBEV 1100-2 S) The carbon brushes are almost
completely worn. If the brushes are completely worn, the machine switches off
automatically. Have the brushes replaced by an authorized service centre.
Permanently lit – overload
(SBEV 1300-2, SBEV 1300-2 S, SBEV 1100-2 S) If the machine is subject to long
periods of contin-uous overloading, the power input of the machine is limited.
This prevents the further unauthorized heating of the motor.
Run the machine in idling until it cools down and the electronic signal
display switches off.
Accessories
Use only genuine Metabo accessories.
Use only accessories which fulfil the requirements and specifications listed
in these operating instructions.
Fit accessories securely. Secure the machine if it is operated in a bracket.
Loss of control can cause personal injury.
