Recommendations about safety use
Recommendations about safety use of flap wheels according GOST 52588-2011
Flap wheels are to be used only on the specially designed equipment.
Before starting work you are to check equipment and be sure that wheels were not broken during transportation or because of careless storage.
Spindle rotation frequency must not exceed number of rotations per minute (min-1), indicated on the wheel.
During work wheel rotation direction must coincide with arrow on the label.
To fix the wheel on machine spindle without slant, to screw it up with specially designed clamp. To be sure that wheel is properly fixed with snap ring of the required dimension (if necessary).
To switch the machine on and check wheel rotation at idle speed. There should be no hopping or axis displacement when the wheel rotates. The sanding starts when the wheel is at the max. number of rotations per minute.
While working avoid sudden loadings, especially when you start processing sharp edge.
Effective sanding by wheels is made during optimal load on them in accordance with required modes of exploitations of the used equipment.
Use the air suction device in the sanding area.
During work its necessary to follow protective measures:
wear eye protection wear gloves
wear a respirator not permitted for wet grinding (depends on coated abrasives features and used tools)
wear hearing protection
Recommendations about storage
Recommendations about storage of flap wheels
Storage warranty period – 12 months from the production date.
Storage temperature not bellow +2 °С.
Not used wheels to keep in mill package.
