- Abstract
The chainsaws are widely used in rural area. To keep them in a good state of use and maintenance it is necessary to carry out maintenance in an appropriate way. In this research chainsaws were characterized according to power classes and the motor, transmission and cutting assembly. We used a questionnaire to collect information from 73 chainsaws in use by rural producers. As result, it was verified that 63% of evaluated the chainsaw belong to the middle class power, these 82,6% presented the angle of sharpening of the chain teeth out of the recommended standard. It should be noted that the cleaning of the spark plug and the inversion of the saber were carried out in 70% of the chainsaws evaluated and 45% of machines showed wear in crown/pinion assembly. In the cutting set the chainsaws of the Middle class, it is evident that 82.6% of the verified units had sharpening angle of the chain teeth outside the recommended standard. Chainsaws of the middle and heavy classes presented the greatest number of problems. It should be noted that lack of maintenance can reduce the operational efficiency and the service life of the chainsaw.
