Two-handed start option boosts safety Stanley has developed a new ergonomic two-handed start solution that keeps the operator's hands away from rotating spindles and pinch points while using DC electric nut runners. A low force spring-loaded sleeve with a second switch allows the operator to grip the tool comfortably in any orientation. Both switches must be actuated within 500 meters for the tool to start. The option is available on any E23L through E55L QPM model.
