Info

When you select a hand-held power tool, you not only infl uence the task the tool is intended to perform, but also the operator´s work situation and the entire working environment. Combined, these factors have a major infl uence on operator health, safety and productivity. Based on more than 50 years of research, testing and experience, this book examines the interaction between these factors.
