| Abstract | This research compared the operational efficiency between gasoline and battery operated chainsaws under 3 different aspects; cutting speed, noise, and vibration levels. The test was performed on dried eucalyptus logs with a diameter of 13 cm. Each type of chainsaw was used on 3 randomly selected logs (replicates), and each log was cut into 10 slides (repetitions). The mean differences of each of the parameters between the types of chainsaws were tested using an Independent-samples T-test. The results showed that the average time per cycle of wood cutting for the battery operated chainsaws was significantly less than the gasoline chainsaws (p = 0.033), with a mean value of 11.57 and 12.90 seconds, respectively. The operating noise level of the battery chainsaw was significantly lower than that of the gasoline chainsaw (p < 0.001), with a mean value of 81.25 and 94.65 dB(A), respectively. The mean noise level of the battery chainsaw was 15% less than the gasoline chainsaw. The operating vibration level of the battery chainsaw was statistically significant and less than that of the gasoline chainsaw (p < 0.001), with a mean value of 0.19 and 1.30 m/s2, respectively. The vibration while operating a battery chainsaw was 7 times less than a gasoline chainsaw. According to the current research, we conclude that battery chainsaws can run faster and are less affected by noise and vibration than gasoline chainsaws. |
