Easy-to-grip front loop handle and soft-grip rear handle allow for comfort and a flat motor housing allows the machine to be laid flat when not in use. An adjustment lever allows for tool-less tensioning of the chain whilst an automatic oil pump allows the chain oil flow to be easily adapted to the air temperature and oil viscosity.
