Electrical safety
Observethefollowingruleswhenworkingonelectricalequipments.
Important:
Use only approved tools and test equipments. Some hand tools have handles
covered with a soft material that does not insulate you when working with live
electrical currents.
Many customers have rubber floor mats near their machines that contain small
conductive bers to decrease electrostatic discharges. Do not use such kind of mat
to protect yourself from electrical shock.
