How to Lubricate

1. Fill the Oil Reservoir:

Chainsaws have a separate reservoir for bar and chain oil, which should be filled according to the manufacturer's instructions. 

2. Use the Correct Oil:

Always use a dedicated bar and chain oil, not regular engine oil or vegetable oil, as these are not formulated to withstand the heat and friction of a chainsaw. 

3. Check the Lubrication System:

Start the chainsaw with the chain brake off. 

Rev the engine a few inches from a piece of cardboard or a tree trunk. 

A visible spray of oil on the surface indicates that the lubrication system is working correctly. 

When to Lubricate

Before Use:

A new or newly sharpened chain should be saturated with oil by placing it in a bag with bar oil and letting it soak, according to YouTube. 

Regularly During Use:

The chainsaw's oiler system automatically feeds oil to the chain while you are cutting. 

As Needed:

If the chainsaw begins to run hotter or if you notice increased friction, it's a sign that you need to check your oil level.
