Flex-Hone Tool Instructions - RPM, Lubricant, Cross-Hatch Honing Procedure

This document is a photograph of the instruction panel printed on a Flex-Hone® tool box. It provides a seven-step usage procedure for the Flex-Hone cylinder honing tool. Key instructions include: using 10-30 weight oil or Flex-Hone Oil as a lubricant, except when honing hydraulic brake cylinders, in which case brake fluid should be used as the honing lubricant; keeping the tool rotating during both entry into and removal from the cylinder; operating within the recommended 500-800 RPM range while avoiding air tools and high-speed motors; using 60-120 strokes per minute depending on RPM, with final stroking accelerated to achieve a 45 degree cross-hatch angle; limiting honing time to approximately 20-45 seconds per cylinder; avoiding solvents for honing or cleaning; and cleaning cylinders after honing with warm or hot water and detergent using a brush, followed by oiling the cylinder. A reader learns the correct lubrication, speed, stroke rate, duration, and post-honing cleaning procedure for using this tool on engine or brake cylinders.
