How do I lubricate the bar and chain?

Chainsaws from McCulloch are self-lubricating. Use only Universal powered by McCulloch bar and chain oil. This oil has been specially developed to retain its viscosity at the extreme temperatures generated by the chain and bar. If the bar is fitted with a nose roller, this should also be lubricated regularly.
