WARNING: Perspiration can pool inside the handle of the GH700/750 electric trimmer/edgers, collecting around the small Honeywell microswitch which is activated by the black spring-loaded external toggle. The switch will short out and burn, rendering the trimmer completely useless (no "internal" replacement parts available to customers) AND CAUSING ELECTRIC SHOCK TO THE OPERATOR. Recommend wearing gloves when operating B&D electric yard tools.
