For your safety.
Do not use this machine before you have thoroughly read and completely understood these operating instructions, including the figures, specifications, and safety regulations.
Please also observe the relevant national industrial safety regulations (e.g. in Germany: BGV A2, BGR 500).
Non-observance of the safety instructions in the said documentation can lead to an electric shock, burns and/or severe injuries.
This Instruction Manual should be kept for later use and enclosed with the power tool, should it be passed on or sold.
Intended use of the machine.
This machine is intended for grinding metal materials (except magnesium) using the grinding belts recommended by FEIN in weather-protected environments.
Special safety instructions.
Wear personal protective equipment. Depending on application, use face shield, safety goggles or safety glasses. Where 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.
While working, do not wear loose clothing, jewellery or open, long hair. Despite protective devices, loose objects can be snagged or caught by moving parts and lead to injury.
Do not use worn, torn or heavily clogged grinding belts. Handle grinding belts carefully and store them according to the manufacturer's instructions. Do not bend or fold grinding belts! Damaged grinding belts can tear, be flung away and injure someone.
Do not use grinding belts or other accessories which are not specifically designed and recommended by the power tool manufacturer. Safe operation is not ensured merely because a grinding belt or accessory fits your machine.
Always use the protective devices attached on the machine. The protective devices must be securely mounted to the machine in order to achieve maximum safety. The protective devices are supposed to protect the user from grinding particles thrown from the machine and from accidental contact with the grinding belt.
Warning! Danger of fire and explosion! When grinding metals (e.g., aluminium), dust develops that may be combustible or explosive. Do not operate the machine near flammable materials. Sparks could cause these materials to ignite.
Warning! Danger of fire! When grinding metals, glowing metal and sanding-belt particles develop that are collected in the chip/grinding-dust box. Before emptying, the contents of the chip/grinding-dust box must have cooled down sufficiently and may only be disposed of in suitable containers.
Pay attention that other persons are not put at risk from sparking. Remove flammable materials in close vicinity. Sparking occurs when grinding metal.
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.
The workpiece must always lie securely on the grinding rest and the stop. Workpieces that are too small or too thin may not be worked. Danger of injury from workpieces being thrown from the machine.
The surface being worked can become very hot. Do not touch it with your hands.
Never touch the running grinding belt. Danger of injury.
In situations of danger, immediately press the safety pushbutton. The machine runs on for approx. 50 seconds.
Clean the ventilation openings on the power tool at regular intervals using non-metal tools. The blower of the motor draws dust into the housing. An excessive accumulation of metallic dust can cause an electrical hazard.
Ensure that the machine is positioned securely and horizontal. Serious injuries can be caused if the machine tips over during operation.
The mains plug of the machine may be mounted only by a qualified electrician. The protective conductor in the mains socket outlet must be connected with the protective earthing of the mains supply.
Pull out the mains plug for maintenance and repair! Switching the machine on unintentionally can lead to serious injuries.
Have the electrical safety of the machine checked regularly in accordance with statutory regulations. For machines that have not been checked, there may be danger of electrical shock!
Check the rotation direction of the motor before starting the operation of the machine for the first time. If the rotation direction of the motor is incorrect, the workpiece can be thrown from the machine and cause an accident. The rotation direction may be changed only by a qualifiedelectrician.
Make sure that you or other persons are not standing directly next to the grinding belt when switching the machine on. The grinding belt can tear apart and cause serious injuries.
Handling hazardous dusts
For work procedures with this power tool where material is removed, dusts develop that can be hazardous to one's health.
Contact with or inhaling some dust types, e. g. asbestos and asbestos-containing materials, lead-containing coatings, metal, some wood types, minerals, silicate particles from materials containing stone, paint solvents, wood preservatives, antifouling paints for vessels, can trigger allergic reactions to the operator or bystanders and/or lead to respiratory infections, cancer, birth defects or other reproductive harm. The risk from inhaling dusts
depends on the exposition. Use dust extraction matched appropriately for the developing dust, as well as personal protective equipment and provide for good ventilation of the workplace. Leave the processing of asbestos-containing materials to specialists.
Wood and light-metal dust, hot mixtures of grinding dust and chemical materials can self-ignite under unfavourable conditions or cause an explosion. Avoid sparking in the direction of the dust collector as well as overheating of the power tool and the materials being sanded, empty the dust collector/container in time, observe the material manufacturer's working instructions, as well as the relevant regulations in your country for the materials being worked.

Assembly instructions (figure 5)
Fasten the machine to the floor using suitable dowel/bolt connections.
All connections must withstand the forces that arise during working.
Faulty assembly can cause the machine to tip over during operation and lead to serious accidents.
Electrical connection.
The electrical connection, which is to be provided by customer, must be carried out by a qualified electrician.
Observe mains voltage: The mains voltage and the frequency of the power source must agree with the data on the type plate of the machine.
Before starting operation for the first time, check the rotation direction of the motor. The rotation direction may be changed only by a qualified electrician.
Adjustments.
Before any work on the machine itself, pull the mains plug.
Adjusting the spark guard (1).
Loosen wing bolt (2) and adjust the spark guard (1) in such a manner that the grinding belt is covered as far as possible.
Tighten wing bolt again.
Adjusting the grinding rest (3) (figure 2).
Loosen star-knob bolt (5) and adjust the gap size to 2 mm (max.).
Tighten the star-knob bolt again.
Adjusting the belt tracking.
Switch the machine on only briefly and check the belt tracking. If the grinding belt moves left or right, adjust the belt tracking with the starknob bolt (8) until centred.
If the belt tracking cannot be adjusted centred:
Clean the drive wheel (13) and the contact wheel (12) with compressed air.
Check the drive wheel and the contact wheel for wear, deformation and damage. Have damaged components replaced without delay!
