Maybe.
Driving a car is using transport, and using a chainsaw is working with wood. I have never read the old testament, but depending on how you interpret it, they could easily be forbidden.

cars and chainsaws are out
because they involve igniting a power source fellas. you werent allowed to light or extinguish stuff, so for example using lekky or turning your car on (or off!) counts as "bad".

this goes as far as leaving lights on for the duration of the sabbath (and other holy days) or using timers (somehow theyre allowed, dont ask me im not practicing or really that much in the know) - and the use of a metal sheet on the cooker so some areas stay hotter than others for cooking - phenomenal waste of gas / electricity in my book.
