Special Safety Instructions

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!
a) Do not use a damaged accessory. Before each use, inspect the accessory such as the abrasive wheel for chips and cracks. After inspecting and installing an accessory, position yourself and bystanders away from the plane of the rotating accessory and run the power tool at maximum no-load speed for one minute. Damaged accessories will normally break apart during this test time.
b) 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.
c) Never grind on the sides of a grinding wheel. Grinding on the side can cause the wheel to break and fly apart.
The grinding wheel must match the machine. Observe the maximum grinding wheel diameter and thickness. The hole diameter must match the back flange without play. Do not use adapters or reducers.
Do not drill grinding wheels.
Do not trim grinding wheels.
The grinding wheels must be fitted perfectly and turn freely.
Prior to using the grinding wheels, ensure that they are free from defects. A sound inspection has to be carried out to detect cracks.
Damaged, eccentric or vibrating or deeply furrowed sanding discs must not be used.
When clamping the grinding wheels, only the flanges included in the delivery must be used. The intermediate layers between the flange and grinding tool must be made of elastic materials, e.g. soft cardboard, etc.
Protect grinding wheels against shocks, bumps, and grease.
Grinding discs must be stored and handled with care in accordance with the manufacturer’s instructions. Do not touch the rotating grinding wheel!
Always use the guard (7), the workpiece support (8), the transparent guard/Eye preservers (9), and the spark deflector (10) as required for the tools;
Only works when the safety cover (1) and sanding belt cover (16) are fitted.
Swivel the eye preservers (9) downwards before grinding.
Use the perimeter (not the sides) of the grinding wheels for grinding.
Do not reduce the speed of the grinding wheel by pressing on the sides.
The workpiece to be processed must be large enough, or small enough, to be held safely with both hands.
Only work when the grinding wheels are fitted to minimize the risk of coming into contact with the rotating spindle.
High temperatures can result after long-term operation.
WARNING
Always wear eye goggles, hearing protection, and protective gloves. Use other available personal protective equipment, e.g. suitable protective work clothing. 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.
The workpiece can become hot during grinding.
Do not allow water within the vicinity of electric machine parts or close to people in the working area.
If a grinding material blockage occurs, switch off the grinder immediately, allow the motor to stop, and unplug the grinder. Identify the cause and remove the blockage.
Clean, check and perform maintenance work on the machine and guard devices regularly. Regularly clean the inside of the grinding wheels and belt grinder housing. The grinding wheels and sanding belt must be able to rotate freely within the housing.
Unplug when the grinder is not in use, before making any adjustments or carrying out modifications, repairs, or maintenance.
Regularly check the power cable on the grinder and have it repaired by an approved expert if damaged.
Regularly check extension cables and replace them if damaged.
Check the grinder for possible damage: Before using the grinder, protective devices or slightly damaged components must be carefully checked to ensure they are operating perfectly and as intended. Check that moving parts are in perfect working order and do not jam and check whether parts are damaged. All parts must be correctly installed and fulfill all conditions necessary to ensure the perfect operation of the grinder. Damaged protective devices and parts must be repaired or replaced according to specifications by an authorized specialist workshop.
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, and asbestos. Other known diseases are e.g. allergic reactions and 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, and 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.
