摘要： An operator operates a throttle lever and by maximizing the extent of said operation, the drive state is initiated, and the crank shaft rotation rate R increases and reaches the maximal value (RC) thereof. Subsequently, the operator operates the dressing operation lever so as to be in a second state at elapsed time (t0) while keeping the extent of the throttle lever operation maximized. Because a microswitch is turned off, the crank shaft rotation rate (R) is controlled in a range of R1

摘要： A chainsaw in which a remaining amount of chain oil to be supplied to a saw chain can be easily checked is provided. In a chainsaw 1 including: a saw chain 6 driven by a motor embedded in a main body; and an oil tank 11 in which the chain oil to be supplied to the saw chain 6 in wood cutting process is stored, an illumination unit (LED 15) is provided in vicinity of the oil tank 11. In this manner, the chain oil of the oil tank 11 positioned on a left side of the LED 15 can be illuminated. This illumination unit is configured to be used also as an illuminating device for illuminating the vicinity of the saw chain 6, that is, an area indicated by dotted lines from 21c to 21d. According to the present invention, in a dark location, the remaining amount of the chain oil can be checked, and besides, a positional relationship among the chainsaw 1 main body, the saw chain 6, and the periphery thereof can be easily visually checked, so that the working efficiency can be improved.

摘要： In a hedge trimmer, a main body is configured of: a main body front portion on a front side (a side on which the cutting blade protrudes); a main body rear portion on a rear side; and a supporting portion for connecting them on a lower side. One end of a main handle and the other end of the same are connected to an upper portion of the main body front portion on the rear end side and an upper portion of the main body rear portion on the front end side. The main handle has a linear shape in parallel to a longitudinal direction of a cutting blade. In this configuration, the main handle is set in substantially parallel to the supporting portion, and a grip space is formed between the main handle and the supporting portion.
