Frequently Asked Questions: Chainsaws
Find the answers to some of the common questions and queries about McCulloch chainsaws.
How do I lubricate the bar and chain on my chainsaw?
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.
Why does my chainsaw chain pull or cut to one side?
Conditions that could cause a chainsaw chain to cut crooked are:
1. Dull cutters damaged by rocks or other hard objects. It's important to remove all nearby objects before using a chainsaw.
2. Different depth gauge settings from left to right. Keep all depth gauge settings equal from left to right.
3. Different top-plate angles from left to right. It's important to keep all top plates equal length.
4. A worn guide bar. A badly worn guide bar will definitely cause a chain to cut to one side.
My chainsaw starts and then dies what is wrong?
This could be a number of things and is most likely fuel or storage related.
Over a short period of time, fuel will become stale. If the unit is stored with stale gasoline, the system will become clogged or restricted. Fuel related failures are not warranty.
This would need to be serviced by a local Authorised service center.
When should I replace the chain for my chainsaw?
The chain should be replaced if :
1. The drive links are burred and do not fit into the bar correctly.
2. If any of the cutter teeth or drive links are broken or bent.
3. If the chain has been sharpened over two thirds the length of the chain.
