The Jig Saw is compact and lightweight. Its T-shank blade change system allows the user to insert the blade just without the need for any tools, and when it’s time for a blade change, a turn of knob ejects the blade, so there is no need to touch a hot blade. This Jig Saw also features an always on blower and integrated LED light for enhanced visibility in the cutting area. The sophisticated electronics package includes Electronic Motor Protection (EMP), which protects the motor against overload and ensures a long lifetime and the Electronic Cell Protection (ECP) protects the battery (sold separately) against overload, overheating and deep discharge.
