Just bought a Brown & Sharpe 618 Micromaster. Small issue
Apr 17, 2018· The Brown and Sharpe 618 operation and maintenance manual suggests purging the cross feed cylinder of air to cure erratic motion. If that does not work it suggests checking the ways for adequate lubrication, checking the piston rod for damage, inspecting the piston seal for leakage, and verifying that there are no leaks in the hydraulic lines.
