Special Safety Instructions

General Safety Recommendations for Grinding, Sanding, Wire Brushing or

Abrasive Cutting

Use

a) This power tool is intended to function as a grinder, sander, wire brush or cut-off tool. 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.
b) Operations such as polishing are not recommended to be performed with this power tool. Operations for which the power tool was not designed may create a hazard and cause personal injury.
c) Do not use accessories which are not specifically designed and recommended by the tool manufacturer. Even if an accessory can be attached to your power tool, this does not ensure safe operation.
d) 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.
e) The external diameter and thickness of your accessory must be within the capacity rating of your power tool. Incorrectly sized accessories cannot be adequately guarded or controlled.
f) The threaded mounting of accessories must match the grinder spindle thread. For accessories mounted by flanges, the arbour hole of the accessory must fit the locating diameter of the flange. Accessories that do not match the mounting hardware of the power tool will run out of balance, vibrate excessively and may result in a loss of control.
g) Do not use damaged accessories. Inspect accessories such as grinding discs before each use for chips and cracks and inspect backing pads for cracks, tear or excess wear and wire brushes for loose or cracked wires. If a power tool or accessory is dropped, inspect for damage or install an undamaged accessory. After inspecting and installing an accessory, position yourself and bystanders away from the plane of the rotating accessory and run the power tool at the maximum no-load speed for one minute. Damaged accessories will normally break apart during this test time.
h) Wear personal protective equipment. Use a face shield, safety goggles or safety goggles depending on the application. If necessary, wear a dust mask, hearing protectors, gloves and a workshop apron capable of stopping small abrasive or workpiece fragments. Eye protection must be capable of stopping flying debris generated by various operations. A dust mask or respirator must be capable of filtering particles generated by your operation. Prolonged exposure to high intensity noise may cause hearing loss.
i) Keep bystanders a safe distance away from the work area. Anyone entering the work area must wear personal protective equipment. Fragments of a workpiece or broken accessory may fly off and result in injury beyond the immediate area of operation.
j) Only hold the cordless tool by its insulated grip areas while completing work where the tool may come into contact with hidden power lines or its own power cable. Cutting accessory contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.
k) Position the cord clear of the rotating accessory. If you lose control, the cord may be cut or snagged and your hand or arm may be pulled into the rotating accessory.
I) Never lay the power tool down until the accessory has come to a complete stop. The rotating accessory may grab the surface and pull the power tool out of your control.
m) Do not run the power tool while carrying it at your side. Accidental contact with a rotating accessory could snag your clothing, pulling the accessory into your body.
n) Regularly clean the power tool’s air vents. The motor’s fan will draw the dust inside the housing and an excessive accumulation of powdered metal may cause electrical hazards.
o) Do not operate the power tool near flammable materials. Sparks could ignite these materials.
p) Do not use accessories that require liquid coolants. Using water or other liquid coolants may result in electrocution or shock.

Kickback and related warnings

Kickback is a sudden reaction to a pinched or snagged sanding wheel, backing pad, brush or any other accessory. Pinching or snagging causes the rotating accessory to stall rapidly, This in turn causes the uncontrolled power tool to be forced in the opposite direction from which the accessory is rotating at the pinched or snagged point. For example, if an abrasive wheel is snagged or pinched by the workpiece, the edge of the wheel entering the pinch point can dig into the surface of the material causing the wheel to climb out or kick out. The abrasive wheel may either jump toward or away from the operator, depending on direction the disc is moving at the pinch point. 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 if suitable precautionary measures are taken as described below.
a) Maintain a firm grip on the power tool and position your body and arm so that you can resist kickback forces. Always use the additional handle, if provided, for maximum control over kickback or a 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 a rotating accessory. The accessory may kickback over your hand.
c) Do not position your body in the area where the power tool will move if kickback occurs. Kickback will propel the tool in the direction opposite to the grinding wheel’s movement at the pinch or snag point.
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 or toothed saw blade. Such blades create frequent kickback and can cause you to lose control.

Safety Warnings Specific for Grinding and Cut-Off Grinding

a) Use only wheel types that are recommended for your power tool and the specific guard designed for the selected wheel. Wheels for which the power tool was not designed cannot be adequately guarded and are unsafe.
b) The grinding surface of the center depressed wheels must be mounted below the plane of the guard lip. An improperly mounted grinding wheel that projects through the plane of the guard lip cannot be adequately guarded.
c) The guard must be securely attached to the power tool and positioned for maximum safety so that the least amount of wheel is exposed towards the operator. The guard helps to protect operator from broken wheel fragments and accidental contact with the wheel and sparks which could ignite clothing.
d) Grinding media must be used only for recommended applications. For example: do not grind with the side of the cutting disc. Cutting discs are intended for grinding using the edge of the disc. Applying force to the sides of these discs may cause them to shatter.
e) Always use undamaged wheel flanges that are the correct size and shape for your selected grinding wheel. Proper wheel flanges support the grinding wheel, reducing the possibility of breakage. Flanges for cutting discs may be different from grinding wheel flanges.
f) Do not use worn down grinding wheels from larger power tools. Grinding wheels intended for larger power tools are not suitable for the higher speed of a smaller tool and may break.

Additional Safety Warnings Specific for Cut-Off Grinding

a) Do not “jam” the cutting disc or apply excessive pressure. Do not attempt to make an excessively deep cut. Overstressing the cutting disc increases the load and makes the disc more susceptible to twisting or bending in the cut and more likely to kick back and break.
b) Do not position your body in line with or behind the rotating cutting disc. When the cutting disc is moving away from your body at the point of operation, any kickback can propel the spinning disc and the power tool directly towards you.
c) If the cutting disc is stuck or when interrupting a cut for any reason, switch off the power tool and hold the power tool motionless until the disc comes to a complete stop. Never attempt to remove the cutting disc from the cut while the disc is in motion; otherwise kickback may occur. Investigate and take corrective action to eliminate the cause if a disc becomes stuck.
d) Do not restart the cutting operation in the workpiece. Let the cutting disc 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.
e) Support panels or any oversized workpiece to minimize the risk of cutting disc pinching and kickback. Large workpieces tend to sag under their own weight. Supports must be placed under the workpiece near the line of the cut and near the edge of the workpiece on both sides of the wheel.
f) Use extra caution when making “pocket cuts” into existing walls or other blind areas. The protruding cutting disc may cause kickback when cutting gas or water pipes, electrical wiring or other objects.

Safety Warnings Specific for Sanding Operations

a) Do not use excessively large sanding disc paper. Follow the manufacturers recommendations when selecting sandpaper. Larger sandpaper that extends beyond the sanding pad presents a laceration hazard and may cause snagging or kickback, or may cause the disc to tear off.

Safety Warnings Specific for Wire Brushing Operations

a) Be aware that wire bristles are thrown by the brush even during ordinary operation. Do not overstress the wires by applying excessive load to the brush. Wire bristles can easily penetrate light clothing and/or skin.
b) If a guard is recommended for wire brushing, do not allow the wire wheel or brush to come into contact with the guard. The wire wheel or brush may expand in diameter due to the work load and centrifugal forces.

Additional Safety Instructions

WARNING – Always wear protective goggles.

Use elastic cushioning layers if they have been supplied with the grinding media and if required. Observe the specifications of the tool or accessory manufacturer! Protect discs from grease or impact! Grinding wheels must be stored and handled with care in accordance with the manufacturer’s instructions.
Never use cut-off wheels for roughing work! Do not apply pressure to the side of cut-off wheels. The workpiece must lay flat and be secured against slipping, e.g. using clamps. Large workpieces must be sufficiently supported.
If accessories with threaded inserts are used, the end of the spindle may not touch the base of the hole on the sanding tool. Make sure that the thread in the accessory is long enough to accommodate the full length of the spindle. The thread in the accessory must match the thread on the spindle. See page 3 and the 12. Technical Specifications chapter for more information on the spindle length and thread.
It is recommended to use a stationary extraction system and to place a ground fault circuit interrupter (GFCI) downstream. If the angle grinder is shut down via the GFCI, it must be checked and cleaned. See the 8. Cleaning chapter for more information on cleaning the motor.
Damaged, eccentric or vibrating tools must not be used.

Avoid damage to gas or water pipes, electrical cables and load-bearing walls (building structure). 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 the machine with a defective additional handle. A damaged or cracked safety guard must be replaced. Never operate a machine with a defective safety guard.
This power tool is not suitable for polishing work. Improper use of the machine will void the warranty! The motor may overheat and damage the electric power tool. We recommend using our angle polisher for polishing work.
Secure small workpieces, for example by clamping them in a vice.

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 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.

• Lock the spindle (see chapter 6.1). Turn the two hole nut (8) anticlockwise using the two-hole spanner (9) to unscrew.

Use

Switching on and off

  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 and keep it away from dust deposits. After switching off the machine, only set 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 securely and concentrate.

Machines with a slide switch

Switching on: push the slide switch (4) forwards. For continuous operation, tilt it downwards until it engages.
Switching off: press the rear end of the slide switch (4) and release it.

Working directions

Grinding and sanding operations:
Press down the machine evenly on the surface and move it back and forth so that the surface of the workpiece does not become too hot.
Rough grinding: position the machine at an angle of 30° – 40° for the best working results.

Cut-off grinding

Always work against the run of the disc (see illustration). Otherwise the machine may kick back from the cut in an out of control manner. Guide the machine evenly at a speed suitable for the material being processed. Do not tilt, apply excessive force or sway from side to side.

Wire brushing:
Press down the machine evenly.

Cleaning

Particles may become deposited inside the power tool during operation. This impairs the cooling of the power tool. Conductive build-up can impair the protective insulation of the power tool and create an electrical hazard.
