Choose the Correct Fit
Confirm the cut-off machine model and serial prefix. Use the exact service diagram rather than a general screw-bar description.
Disconnect power before vise service. Keep the release mechanism, support seat and associated hardware organized during disassembly.
Installation & Care
Inspect the screw engagement and vise movement before installing the replacement. Follow the manufacturer’s assembly procedure and replace damaged associated parts separately.
Verify secure work clamping and release operation before cutting. Do not operate the saw with a vise that binds, slips or fails to hold the work.
