flammable gas, place exposed to high temperature, dew condensation, direct sunlight,
wind and rain, or place exposed to vibration or impact.
If the Handy GOT is used in such a place, electrical shock, fire, malfunction, product
damage or deterioration may caused.
• Never drop cutting chips and electric wire chips into the ventilation window of the Handy
GOT when you drill screw holes or perform wiring.
