Makita 18V LXT Lithium-Ion Cordless Recipro Saw Kit, var. spd., tool-less blade change, case (5.0Ah). Manufacturer's Product Number: MK-XRJ04T. The Makita 18V LXT® Lithium-Ion Recipro Saw Kit combines cutting speed with convenience features for faster, more efficient cutting. It’s powered by the industry’s fastest-charging 18V lithium-ion batteries, allowing users to remain in one battery platform and use the same fast-charging 18V batteries on the XRJ04T as they use across the Makita 18V LXT® cordless tool line-up. The XRJ04T is equipped with efficiency features for faster cutting. The long 1-1/4” stroke length increases cutting efficiency, and the refined crank mechanism design minimizes blade deflection and reduces vibration. Convenience features include a large two-finger variable speed trigger, electric brake, and “tool-less” blade change for faster blade installation and removal. Features

WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry products, and
• arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.
