DO NOT USE THE HEAVIEST LINE!
Use either 2.0mm or possibly 2.4mm line, do not use thicker as it will cause problems as the machine is not powerful enough.
Oil mixture ratio depends on the oil you purchase but as a guide mix
Mineral Oil at 25:1
Synthetic oil 50:1
If you are in the UK go to Homebase and buy a Fuel Mixing bottle to make it easy.
Or Call ALM Manufacturing 01423 797208 for advice/stockists
