Not be used for the grinding operations other than its intended purpose.
14. Information emitted noise and vibration.
The values are measured according to EN 60745.
Sound pressure level: Lp
Sound power level: Lw
Work with earmuffs!
Level of vibration a
In rough surface grinding and polishing: vibrations generated: a
uncertainty K = 1,5 m/s
Sanding with sandpaper: vibrations generated a
of generated vibrations can be used for comparison with other power tools. That level of vibration
generated is representative of the most common uses of angle grinder. If grinding is used for other
activities, working with other instruments or if not maintained as prescribed, the level of generated
vibrations can be changed.
15. Preparing for the job.
15.1. Installation of protective equipment.
Before carrying out any activities grinders unplug the plug from the feed network.
