Chainsaw refueling equipment in forestry harvesters

摘要

An object of the present invention is to provide a chain saw lubricating device that is devised so that even if the chain saw is used to cut a thick tree having a diameter of 30 cm or more, the saw chain does not run out of oil. An electric pump (13) is provided in a chain saw oil supply device (10) in a forestry harvester. At the same time as the operation, the electric pump 13 is operated to continuously supply oil to the saw chain during operation of the chainsaw. [Selection] Figure 2
