This MetaboHPT 36V brushless jig saw offers users best in class cutting performance both in the shop or on the job site. Low vibration enables smooth cutting, while a low startup speed ensures ease when aligning the blade to the cut line. When the saw is in use, an auto mode enables the speed to automatically switch from 1,400 strokes per minute to 3,500 strokes per minute, and the variable control feature helps maintain speed. The CJ36DAQ4 is compatible with 36V MetaboHPT (and Hitachi) Lithium Ion slide batteries and the tool itself is warranted from manufacturing defects for a lifetime. Battery and charger sold separately. SPEED: Adjust from 800-3,500 strokes per minute ORBITAL ACTION: 4-Stage orbital action helps to reset the blade for the next cutting stroke AUTO MODE: Vibration is reduced when in a ��no-load�� situation, making blade alignment easier SPEED CONTROL: Variable speed control enables a change to the stroke speed LOCK-On SWITCH: On-lock switch improves operability under continuous working situations CUTTING ANGLE: 45 degrees to the right and left
