JS-131 Joint Clean-out Saw

Part Number: SX77131

The JS-131 Gas – Joint Clean-out Saw is a gas-powered walk-behind saw used for joint clean-out, concrete sawing, and trench cutting. 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.  A 225 CFM is acceptable with certain blade and jobsite configurations, but 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.
