4. Special Safety Instructions

4.1 Cut-off machine safety warnings

a) The guard belonging to the power tool must be securely attached to the power tool and positioned for maximum safety, thus ensuring that the least amount of wheel is exposed towards the operator. Position yourself and bystanders away from the plane of the rotating wheel. The guard helps to protect operator from broken wheel fragments and accidental contact with wheel.

b) Use only bonded reinforced or diamond cut-off wheels for your power tool. Just because an 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) Wheels must be used only for recommended applications. For example: do not grind with the side of cut-off wheel. 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 diameter 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 arbour size of wheels and flanges must properly fit the spindle of the power tool.

Wheels and flanges with arbour holes that do not match the mounting hardware of the power tool will run out of balance, vibrate excessively and may cause loss of control.

h) Do not use damaged wheels. Before each use, check the abrasive wheels for chips and cracks. If power tool or wheel is dropped, inspect for damage or install an undamaged wheel. After inspecting and installing 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 wheels will normally break apart during this test time.

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 filtrating particles generated by your operation. Prolonged exposure to high intensity noise may cause hearing loss.

j) Keep bystanders a safe distance away from 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.
1) Position the cord clear of the spinning accessory. If you lose control, the cord may be cut

or snagged and your hand or arm may be pulled into the spinning wheel.

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 run the power tool while carrying it at your side. Accidental contact with the spinning accessory could snag your clothing, pulling the accessory into your body.
o) Regularly clean the power tool's air vents. 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

Kickback is a sudden reaction to a pinched or snagged rotating wheel. Pinching or snagging causes rapid stalling of the rotating wheel which in turn causes the uncontrolled power tool to be forced in the direction opposite of the wheel's rotation at the point of the binding.

For example, if an abrasive wheel is snagged or pinched by the workpiece, the edge of the wheel that is entering into the pinch point can dig into the surface of the material causing the wheel to climb out or kick out. The wheel may either jump toward or away from the operator, depending on direction of the wheel's movement at the point of pinching. 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 auxiliary 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 in line with the rotating wheel. Kickback will propel the tool in 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 attach a saw chain, woodcarving blade, segmented diamond wheel with a peripheral gap greater than 10 mm or toothed

saw blade. Such blades create frequent kickback and loss of control.

f) Do not “jam” the 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 binding of the wheel in the cut and the possibility of kickback or wheel breakage.
g) When wheel is binding or when interrupting a cut for any reason, switch off the power tool and hold the power tool motionless until the wheel comes to a complete stop. Never attempt to remove the 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 binding.
h) Do not restart the cutting operation in the workpiece. Let the wheel reach full speed and carefully re-enter 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:

WARNING – Always wear protective goggles.

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).

Always use the additional side handle (3) provided when working with the wall chaser.

The workpiece must lay flat and be secured against slipping, e.g. using clamps. Large workpieces must be sufficiently supported.

The diamond cut-off wheels must fit without play in relation to the support flange. Do not use adapters or reducers.

Diamond cut-off wheels must be stored and handled with care in accordance with the manufacturer's instructions.

Ensure that the diamond cut-off wheels are installed in accordance with the manufacturer's instructions.

Never switch on the machine without the guard installed.

Ensure the sparks emitted during use do not pose any risk,

for example, to the user or other personnel and are not able to ignite inflammable substances. Areas at risk must be protected with flame-resistant covers.

Always keep a fire extinguisher on hand when working in areas prone to fire risk.

ENGLISHen

The diamond cut-off wheels 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.

Damaged, eccentric or vibrating tools must not be used.

Avoid damage to gas or water pipes, electrical cables and load-bearing walls (static).

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.

Reduce dust exposure:

Some of the dust created using this power tool may contain chemicals known to cause cancer, allergic reaction, respiratory disease, 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, arsenic and chromium from chemically-treated lumber, hard wood like oak or beech, metals, asbestos.

The risk from exposure to such substances will depend on how long you or bystanders are being exposed.

Do not let particles enter the body.

To reduce your exposure to these substances: work in a well ventilated area, and work with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.

Observe the relevant guidelines for your material, staff, application and place of application (e.g. occupational health and safety regulations, disposal).

Collect the generated particles 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.

9. Depth of cut

After undoing the cross handled screw (2) you can set the desired cutting depth using the scale (1).

Tighten the cross handled screw (2) back up again.

10. Extracting the stone dust

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.

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 (6). The bayonet catch prevents the suction hose from coming loose while the machine is in operation.

Using a second suction hose 6.30344 allows you to set up the extraction unit at a distance of up to 8 m 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.

11. Switching on and off

Always guide the machine with both hands.

Switch on first, then guide the accessory towards the workpiece.

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 securely and concentrate.

Avoid the machine swirling up or taking in dust and chips. After switching off the machine, only place it down when the motor has come to a standstill.

15 0 ①

Switching on: Push the slide switch (15) forward. For continuous activation, now tilt downwards until it engages.

Switching off: Press the rear end of the slide switch (15) and release it.

12. Working With the Wall Chaser

Always guide the device with both hands on the main handle (5) and side handle (3).

Only use the wall chaser with the side handle (3) attached!

Position the side handle so that it can be gripped firmly without touching the guard.

Contact with live wires energises the metal parts of the housing and can cause electric shock to the operator.

The side handle (3) may be adjusted after the screw (14) is undone. Bring the side handle to the desired position and tighten the hex screw (14).

At the rear end of the guide shoe (12) there is a triangular marking (9). The marking is on the extension of the rear diamond cut-off wheel and is used, when cutting grooves, as a cut indicator.

Place the wall chaser (with the motor switched on) with the guide shoe (12) on the surface into which a groove is to be cut, and slowly guide down until the set cutting depth has been reached.

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 groove is complete, switch off the tool and hold it steady until the diamond cut-offel comes to a stop. Never attempt to remove cutting disc from the cut while the wheel is motion otherwise kickback may occur. Lay pool on its side.

You can remove the remaining strip between the two chases with the chase extraction chisel provided.

Grooves of greater depth cannot be cut into hard material (e.g. cement) in one movement.

13. Cleaning

It is possible that particles deposit inside the power tool during operation. This impairs the cooling of the power tool.

The power tool should be cleaned regularly, often and thoroughly through all front and rear 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.

14. Overload protection

14.1 Safety clutch

There is an automatic safety coupling built-in to the gears of the wall chaser. This protects the operator from the high torque that may, for example, occur if the diamond cut-off wheel is canted during work. The safety coupling protects and at the same time takes the strain off the motor and the gears of the machine. When the safety coupling engages, immediately switch the motor off (do not allow the coupling to drag!),

14.2 Electronic overload protection

In the event of a brief, very high overloading of the machine, the integrated electronic overload protection limits the power consumption and thus prevents the overheating of the machine.

15. Accessories

Use only genuine Metabo accessories.

Use only accessories which fulfil the requirements and specifications listed in these operating instructions.
