This type of research was descriptive. The subjects were seven vehicle maintenance activities in both types of the workshops and the respondents were 8 mechanics for filling out the questionnaire of Nordic Body Map. The results showed that 86 percent (right side) and 71 percent (left side) activities in “X” hydraulic motorcycle shop and 57 percent (right and left side) activities in “Y” non-hydraulic motorcycle shop had a score of medium risk level. In addition, there were 14 percent (right side) and 29 percent (left side) activities in “X” hydraulic motorcycle shop and 43 percent (right and left side) activities in "Y” non-hydraulic motorcycle shop with high risk level. The results of the questionnaire of Nordic Body Map was showed that the mechanics in “X” hydraulic motorcycle felt pain on the waist.
