APPLICATION ADVICE

Because of its application methods, non-sparking tools have to be softer than conventional tools. For this reason, the use of these tools has to be used with special care. Overstraining has to be avoided.

The use of non-sparking tools must not be the only preventive measurement in areas of fire and explosion risk.
For overall protection of staff and equipping, please follow the instructions of your professional association.
