4.1 Safety instructions for abrasive cut-off

machines a) The guard belonging to the power tool must be securely attached and positioned for maximum safety so that the minimum area of the wheel is exposed towards the operator. Ensure that neither you or bystanders are positioned within the plane of the rotating abrasive wheel. The guard helps to protect operator from broken wheel fragments and accidental contact with wheel. b) Only use diamond cut-off wheels for your power tool. Just because the accessory can be attached to your power tool, it does not assure safe operation. c) The rated speed of the accessory must be at least equal to the maximum speed marked on the power tool. Accessories running faster than their rated speed can break and fly apart. d) Abrasive wheels must only be used for the applications recommended. e.g.: Never use the side surface of a cut-off wheel for grinding. Abrasive cut-off wheels are intended for peripheral grinding, side forces applied to these wheels may cause them to shatter. e) Always use undamaged wheel flanges that are of correct size and shape for your selected wheel. Proper wheel flanges support the wheel thus reducing the possibility of wheel breakage. f) The outside diameter and the thickness of your accessory must be within the capacity rating of your power tool. Incorrectly sized accessories cannot be adequately guarded or controlled. g) The abrasive wheels and flange must fit precisely onto your power tool's grinding spindle. Accessories with arbour holes that do not fit the power tool's grinding spindle will run out of balance, vibrate excessively and may cause loss of control. h) Do not use damaged abrasive wheels. Before each use, check the abrasive wheels for chips and cracks. If the power tool or the abrasive wheel is dropped, inspect for damage. Never use a damaged abrasive wheel. Once you have checked and installed the wheel, position yourself and bystanders away from the plane of the rotating wheel and run the power tool at maximum no-load speed for one minute. Damaged abrasive wheels will normally break apart during this test period.

i) Wear personal protective equipment.

Depending on application, use face shield, safety goggles or safety glasses. As appropriate, wear dust mask, hearing protectors, gloves and workshop apron capable of stopping small abrasive or workpiece fragments. The eye protection must be capable of stopping flying debris generated by various operations. The dust mask or respirator must be capable of filtering particles generated by your operation. Prolonged exposure to high intensity noise may cause hearing loss. j) Keep bystanders a safe distance away from the work area. Anyone entering the work area must wear personal protective equipment. Fragments of workpiece or of a broken accessory may fly away and cause injury beyond immediate area of operation. k) Hold the power tool by insulated gripping surfaces only, when performing an operation where the cutting accessory 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. l) Position the cord clear of the spinning accessory. If you lose control of the tool, the cord may be cut or snagged and your hand or arm may be pulled into the spinning accessory. m) Never lay the power tool down until the accessory has come to a complete stop. The spinning accessory may grab the surface and pull the power tool out of your control. n) Do not carry the power tool while it is running. Your clothing could become caught accidentally in the rotating cutting accessory, and this accessory could then drill into your body. o) Regularly clean the ventilation slots on your power tool. The motor’s fan will draw the dust inside the housing and excessive accumulation of powdered metal may cause electrical hazards. p) Do not operate the power tool near flammable materials. Sparks could ignite these materials. q) Do not use accessories that require liquid coolants. Using water or other liquid coolants may result in electrocution or shock.

4.2 Kickback and Related Warnings

WARNING – Always wear protective goggles. Kickback is the sudden response to an abrasive wheel that is jamming while rotating. Jamming causes the rotating accessory to stop abruptly, which in turn causes the uncontrolled power tool to be forced in the direction opposite to the accessory’s rotation at the point of jamming. For example, if an abrasive wheel jams in the workpiece, the edge of the wheel entering into the workpiece can snag, thus causing either kickback or the wheel to break off. Abrasive wheels may also break under these conditions. Kickback is the result of power tool misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below. a) Maintain a firm grip on the power tool and position your body and arm to allow you to resist kickback forces. Always use additional handle, if provided, for maximum control over kickback or torque reaction during start-up. The operator can control torque reactions or kickback forces, if proper precautions are taken. b) Never place your hand near the rotating accessory. Accessory may kickback over your hand. c) Do not position your body either before or behind the rotating wheel. Kickback will propel the tool in the direction opposite to the wheel’s movement at the point of snagging. d) Use special care when working corners, sharp edges etc. Avoid bouncing and snagging the accessory. Corners, sharp edges or bouncing have a tendency to snag the rotating accessory and cause loss of control or kickback. e) Do not use a chainsaw blade, toothed saw blade or segmented diamond disc with slots wider than 10 mm. Such blades create frequent kickback and loss of control. f) Do not “jam” the cut-off wheel or apply excessive pressure. Do not attempt to make an excessive depth of cut. Overstressing the wheel increases the loading and susceptibility to twisting or jamming of the wheel in the cut and the possibility of kickback or wheel breakage. g) If the wheel gets jammed or you interrupt operation for any reason, switch off the power tool and hold the power tool still until the wheel comes to a complete stop. Never attempt to remove the cut-off wheel from the cut while the wheel is in motion otherwise kickback may occur. Investigate and take corrective action to eliminate the cause of wheel jamming. h) Do not restart the tool while in the workpiece. Let the wheel reach full speed and carefully reenter the cut. The wheel may bind, walk up or kickback if the power tool is restarted in the workpiece.

i) Support panels or any oversized workpiece

to minimize the risk of wheel pinching and kickback. Large workpieces tend to sag under their own weight. Supports must be placed under the workpiece near the line of cut and near the edge of the workpiece on both sides of the wheel. j) Use extra caution when making a "pocket cut" into existing walls or other blind areas. The protruding wheel may cut gas or water pipes, electrical wiring or objects that can cause kickback.

4.3 Additional Safety Instructions

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). Always use the additional side handle provided when working with the wall chaser (9). The workpiece must lay flat and be secured against slipping, e.g. using clamps. Large workpieces must be sufficiently supported. The diamond cutting blades must fit without play in relation to the support flange. Do not use adapters or reducers. Diamond cutting blades must be stored and handled with care in accordance with the manufacturer's instructions. Ensure that the diamond cutting blades are installed in accordance with the manufacturer's instructions. Never switch on the machine without the protective cover installed. Ensure that sparks produced during work do not constitute a risk to the user or other personnel and are not able to ignite inflammable substances. Endangered areas must be protected with flame- resistant covers. Make sure that fire-risk areas are always provided with suitable fire extinguishers.ENGLISH en

The diamond cutting blades continue running after the machine has been switched off. Always wear protective goggles, dust mask, gloves, ear protectors and sturdy shoes when working with this tool. Dust from material such as paint containing lead, some wood species, minerals and metal may be harmful. Contact with or inhalation of the dust may cause allergic reactions and/or respiratory diseases to the operator or bystanders. Use a suitable extraction unit! Certain kinds of dust are classified as carcinogenic, especially in conjunction with additives for wood conditioning (chromate, wood preservative). Material containing asbestos must only be treated by specialists. - To achieve a high level of dust collection, use a suitable Metabo vacuum cleaner together with this tool. - The work place must be well ventilated. - The use of a dust mask of filter class P2 is recommended. Follow national requirements for the materials you want to work with. Materials that generate dusts or vapours that may be harmful to health (e.g. asbestos) must not be processed. When working in dusty conditions, ensure that ventilation openings are not blocked. If it becomes necessary to remove dust, first disconnect the power tool from the mains supply (use non-metallic objects) and avoid damaging internal components. Damaged, eccentric or vibrating tools must not be used. Avoid damage to gas or water pipes, electrical cables and load-bearing walls (static). Connect a FI circuit-breaker with max. release current (30 mA) upstream when using the machine outdoors! Pull the plug out of the socket before making any adjustments, converting or servicing the machine. A damaged or cracked additional handle must be replaced. Never operate a machine with a defective additional handle. A damaged or cracked safety guard must be replaced. Never operate a machine with a defective safety guard. Do not switch on the machine if tool parts or guard devices are missing or defective. An electronic error is present if the machine accelerates very quickly to maximum speed when switched on. Other safety-related electronic functions are no longer available. Have the machine repaired immediately (see 16.).

• depending on equipment/not in scope of delivery Before plugging in, check that the rated mains voltage and mains frequency, as stated on the rating label, match with your power supply. To position the safety guard (if required): - Release the clamping screw (12). - Turn the safety guard until the closed section is facing the operator. - Tighten the clamping screw (12) firmly. Make sure that the guard is seated securely - you should not be able to turn the safety guard (19).

6.1 Pivotable main handle

Only work with the main handle (8) engaged. See illustration B on page 2. - Push in the button (7). - The main handle (8) can now be turned 90° to both sides and can be engaged. - Make sure that it is securely positioned: the main handle (8) must be engaged and it should not be possible to move it. See page 2. Switch off the machine. Disconnect the mains plug! - Lie the tool on its side (the scale (2) for depth of cut must be visible). - Release the lever (1) for setting the depth of cut and select the small depth. - Press down the locking button (11) and turn the spindle until you can feel the locking button lock in place (only when tool is stopped!). - Remove and clean the back flange (17), spacers (14) and adjusting nut (13). - Fit the back flange (17) on the spindle. The flange should not turn on the spindle when properly attached. - Fit the cut-off wheel (16) onto the back flange. Make sure the direction of rotation is correct.

6. Initial Operation

The direction of rotation is indicated by arrows on the cut-off wheel and guard. - Fit the spacers (14). For groove width and spacers required, see table on page 2. - Fit the cut-off wheel (15). Make sure the direction of rotation is correct. The direction of rotation is indicated by arrows on the cut-off wheel and guard. Regardless of the groove width, all seven spacers must always be fitted. There must be at least one spacer between the two diamond cut-off wheels. - Screw on the adjusting nut (13). - Press and hold down the locking button (11). - Using a 2-hole spanner, tighten the adjusting nut (13) (18). Since the mounted cut-off wheels protrude from the safety guard, store the tool by placing it on its side, not on the rollers. Carry out a test run: Position yourself and bystanders away from the plane of the rotating wheel and run the power tool at maximum no-load speed for one minute. Damaged abrasive wheels will normally break apart during this test period. Stop immediately if significant vibrations occur or if other defects are noted. If such a situation occurs, check the machine to determine the cause. If you remove the front diamond cut-off wheel and leave only the rear wheel on the machine, the wall chaser is then suited for cutting through materials (e.g. tiles). Release the lever (1) and set the depth of cut. Tighten the lever (1) again. Tip: In the case of very hard concrete and cuts deeper than 35 mm, we recommend setting the cut in two steps to avoid overloading the machine. Caution! Never work without a dust extraction device. Dusts can be harmful to health! Never work without a dust extraction device. The motor can quickly choke on stone dust. Use a suitable Metabo vacuum cleaner (see section15.). To extract stone dust generated during work with the wall chaser, insert the suction hose 30 344 (4 m) in the aperture of the extraction unit (3). The bayonet catch prevents the suction hose from coming loose while the machine is in operation. Using a second suction hose 30 344 allows you to set up the extraction unit at a distance of up to 8m from the work place. (Suction hose not included in scope of delivery). To connect a suction hose without a bayonet catch, use the connection adapter provided. Always guide the machine with both hands. Switch on first, then guide the accessory towards the workpiece. The machine must not be allowed to draw in additional dust and shavings. When switching the machine on and off, keep it away from dust deposits. After switching off the machine, only place it down when the motor has come to a standstill. Avoid inadvertent starts: always switch the tool off when the plug is removed from the mains socket or if there has been a power cut. 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 in a safe position and concentrate. See illustration A on page 2. Torque activation Switching on: Slide the lock (5) in the direction of the arrow and press the trigger (6). Switching off: Release the trigger (6). Continuous operation (depending on features) Switching on: Slide the lock (5) in the direction of the arrow, press the trigger (6) and keep it pressed. The machine is now switched on. Now slide the lock (5) in the direction of the arrow once more to lock the trigger (6) (continuous operation). Switching off: Press the trigger (6) and release. Only use the wall chaser with the additional handle attached (9)! Once the retaining screw is released (10), you can adjust the handle holder in 30° steps to the relevant working position. When the retaining screw is tightened, the 4 fixing pins on the handle holder are introduced into the corresponding holes. Always hold the tool by the main handle and additional handle, using both hands. Position the wall chaser with the rear guide rollers on the work surface. Slowly move the operating machine downward until all guide rollers are lying flat on the work surface. Then pull the machine in the chase direction, e.g. from top to bottom as shown in Fig. A below (page 4) or - for horizontal chases - back towards itself as shown in Fig, B (page 4). Once the channel is complete, switch off the tool and hold it steady until the wheel comes to a stop. Never attempt to remove the cut-off wheel from the cut while the wheel is in motion otherwise kickback may occur. Lay the tool on its side. You can remove the remaining strip between the two chases with the chase extraction chisel provided.

8. Using the machine with only

one diamond cut-off wheel

11. Switching on and off

To clean the motor: To prevent stone dust from collecting inside the wall chaser, you must occasionally clean the motor by blowing compressed air through the air duct on the back of the motor housing, if the machine is used for extended periods. If possible, this process should NOT be carried out indoors/in a confined space. Button (7) for adjusting the handle: Occasionally blow compressed air through the button (when pressed, in all 3 main handle positions). - Overload protection: The electronic signal display (4) lights up and the load speed decreases slightly. The machine is overloaded. Work with a reduced load until the electronic signal display goes out. - Overload protection: The electronic signal display (4) lights up and the load speed decreases dramatically. The motor temperature is too high! Run the machine in idling until it cools down and the electronic signal display switches off. - Metabo S-automatic safety stop: The electronic signal display (4) lights up and the machine SWITCHES OFF automatically. If the slew rate of the current is too high (for example, if the machine suddenly seizes or kickback occurs), the machine switches off. Switch off the machine at the trigger (6). Switch it on again and continue to work as normal. Try to prevent the machine from seizing. See section 4.2. - Restart protection: The electronic signal display (4) FLASHES and the machine does not start. The restart protection is active. If the mains plug is inserted with the machine switched on, or if the current supply is restored following an interruption, the machine does not start up. Switch the machine off and on again. - When switched on, the machine accelerates to maximum speed very quickly, i.e. automatic restriction of the starting current does not work (soft start). An electronic error exists. Other safety-related electronic functions are no longer available. Have the machine repaired immediately (see 16.). Use only genuine Metabo accessories.

= Uncertainty (vibration) The vibration emission level given in this information sheet has been measured in accordance with a standardised test given in EN 60745 and may be used to compare one tool with another. It is also suitable for a provisional estimate of the vibratory load. The specified vibration level applies to the main applications of the power tool. However, if the tool is

used for other applications, with different accessories or when poorly maintained, the vibration level may vary. An estimation of the level of exposure to vibration should also take into account the times when the tool is switched off or when it is running but not actually in use. This can considerably reduce the vibratory load over the entire working period. Identify additional safety measures to protect the operator from the effects of vibration such as: maintain the tool and the accessories, keep the hands warm, organisation of work patterns.
