Internal combustion engines used in chainsaws have many unwanted influences,
mainly environment pollution with exhaust gases and detrimental effects on the
worker’s health due to effects of vibrations, noise and carbon monoxide inhalation.
With the appearance of cordless electric chainsaws, which do not require a wired
connection to the electrical network, it is possible to use chainsaws with an electric
motor in forestry as well. To test these chainsaws in real-life forest conditions three
different cordless chainsaws were compared to a gas-powered chainsaw. In three
days of work 28,43m3 of round spruce wood were produced. The average work
performance of battery-powered chainsaw was 2,18m3
/h, while gas-powered
chainsaw produced 6,34m3/h. It was demonstrated that the effect of the gas-powered
chainsaw was significantly greater than that of a battery saw, however, the
battery-powered saws are more effective for tree diameters lower than 15cm.
