Electrical safety
Observethefollowingruleswhenworkingonelectricalequipments.
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.
