Designed to clean-out existing control joints to prepare for new joint fill application or remove failing or deteriorated existing joint fill material. This machine can be used to remove polyurea, epoxy, and polyurethane joint fill materials. This JS-131 has several key features to provide accuracy, high production rates, and a safe working environment.
The material is milled out of the joint in an upward direction and is collected by the debris collection port. It features a blade guard design with up-cut rotation, which permits easy dust extraction and a secure connection to the dust collection system. A dust collector with a minimum of 350 CFM is recommended for use with this machine for open joint cleanout. 225 CFM is acceptable with certain blade and jobsite configurations. Production speed is significantly dependent upon job site conditions.
The JS-131 joint clean-out saw uses dry diamond blades and cuts to a maximum depth of 3″. It features a secure screw-down depth control for added precision and safety power Source: 13 HP Honda gas engine.
