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 minimise the risk of coming into contact with the rotating spindle.

High temperatures can result after long-term operation.

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 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 fulfil all conditions necessary to ensure perfect operation of the grinder. Damaged protective devices and parts must be repaired or replaced according to specifications by an authorised specialist workshop.

Reduce dust exposure:

Particles generated when working with this machine may contain substances that can

cause cancer, allergic reactions, respiratory diseases, birth defects or other propagation defects. Some of these substances include: Lead (in paint containing lead), mineral dust (from bricks, concrete etc.), additives used for wood treatment (chromate, wood preservatives), some wood types (such as oak or beech dust), metals, asbestos. The risk depends on for how long the user or nearby persons are exposed to the substance.

This dust must not be allowed to enter your body. Do the following to reduce exposure to these substances: Ensure good ventilation of the workplace and wear appropriate protective equipment, such as respirators able to filter microscopically small 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 (see chapter 9.), thus less particles enter the environment in an uncontrolled manner.

Use a suitable extraction unit.

Reduce dust exposure with the following measures:

• Use an extraction unit and/or air purifiers
