Safety Instructions

Note: Failure to follow these Safety Instructions can result in serious injury.
As with all machines, there are typical dangers associated with the operation and handling of a Sanding Belt.
Careful operation and correct handling of the machine significantly reduce the risk of accidents. However, if normal precautionary measures are disregarded, risks of accident for the operator are unavoidable.
The design of this machine is specific to its intended use. Therefore, we strongly advise against carrying out any modifications of the machine or forcing it force it to perform tasks for which it has not been designed.
If you have any questions about the use of this machine and if you do not find the appropriate answer in this Instructions Manual, please contact your dealer who will be able to help you.
General safety rules and guidelines for handling machines

1. For your own safety, first read and become familiar with the entire Instructions Manual before operating the machine. Learn the machine’s applications, its operating limits, and specific hazards.
   This Manual gives also information about the risks involved in case of negligence.

2. Keep guards in place and in perfect working order, do not remove them.

3. Always connect the electrical machinery equipped with mains plug with protective contact (earth contact) to a socket with earth contact.
   When using adapters without earth contact, connect directly to the earth terminal of the machine. Never start a machine that is not connected to an outlet with ground connection.

4. Before turning the machine ON, remove loose clamping levers or keys from the machine. Systematically make sure that there are no loose parts near the moving elements.

5. Provide sufficient working space around the machine. Cluttered work stations and benches invite accidents.

6. Do not operate the machine in a dangerous environment. Do not use the machine in wet or damp areas and do not expose it to rain. Always keep the work area and workstation well lit.

7. Keep children and visitors away from the machine and at a safe distance from the machine and from the work area.

8. Secure the workshop or workroom against unauthorised access. Fit child safety devices, e.g., door latches, lockable main switches, etc. in order to prevent children from turning on.

9. Do not overload the machine. Its performance will be better and the operation safer if it is operated within the specified ranges without exceeding the capacities for which it has been designed.

10. Do not use the machine to perform tasks for which it is not designed. The machine is exclusively designed for its intended use.

11. Wear appropriate clothing. Do not wear loose clothing, gloves, neckties, rings, necklaces or bracelets and other jewellery that may be caught in moving parts of the machine. Wear non-slip footwear. Wear protective hair covering to contain long hair.

12. Always wear safety glasses and a dust mask, if necessary. Proceed according to the accident prevention regulations.

13. Always secure the workpiece in a vice or clamping device. Holding the workpiece with the hands is risky and it is recommended that both hands remain available for handling the machine.

14. Do not overreach. Keep proper footing and balance at all times.

15. Always keep the machine in good working order. Keep the cutting faces sharp and clean for optimum performance. Follow the instructions for cleaning, lubricating and replacing accessory equipment/tools.

16. Always disconnect the machine from the mains before carrying out any maintenance work or replacing machine parts such as saw blade, drill bits, cutting tools etc.

17. Only use the recommended accessories. Follow the instructions in the User Manual. The use of unsuitable accessories may cause accidents.

18. Prevent any accidental starting. Before connecting the equipment to the mains, always check that the operating switch is in OFF position (O).

19. Never stand on the machine. Any tipping over of the machine or contact with the cutting tool can result in very severe accidents.

20. Check for damaged parts. Damaged guards or parts should be properly repaired or replaced before further operation.

21. Never leave a running machine unattended. Always switch off the mains supply. Do not leave the machine unattended until it has come to a complete standstill.

22. Never operate the machine if you are under the influence of alcohol, medication or drugs.

Always wear safety glasses!

Sanding Examples

Example 1
Sanding with the roller.
Place the workpiece on the table and move it to the corner of the table.
Protect the belt with the stop.
Example 2
Flat sanding.
Remove the top guard. Place the workpiece on the belt and secure with the stop.
Example 3
Suction.
Sanding generates dust, which contaminates the atmosphere.
