JISHU HOZEN STEP 1: INITIAL CLEANINGJISHU HOZEN STEP 1: INITIAL CLEANING
Identifying abnormalities through stratified fuguai tags: Interesting findings not known so far Changing Look of the machines: providing sense of pride to the workmen Increased awareness to identify: difficult to clean/lubricate/ inspect areas and the need for counter measures Specific tools developed in-house for cleaning difficult-to-access areas Spectrum covered small capacity welding machines to as big as 100 Ton – capacity machines, where each job goes on for months (to a size of 8.5 m components)

RESULTS OF STEP 1RESULTS OF STEP 1
More than 14000 fuguai tags identified and
attended In a span of about couple of years, 114 machines
were adopted for JH out of 147 machines Concept of doing JH in non-machine areas
introduced e.g. in fabrication/ assembly areas, sub-
stores.
