Stabilize the Gas and the Engine
- Add a fuel stabilizer to your two-stroke gas mixture and fill the chainsaw’s gas tank.
- Run the engine until the machine is warm to coat the entire engine with the stabilized mix.
Drain the Gas
- Dump the gas back into your tank
- Note: because the gas is stabilized, you can use it next season.
- Pump your primer bulb while emptying the gas to flush all the gas out.
Re-start the Engine
- To remove as much gas from the engine as you can, start the engine back up and let it die out.
- Continue to start it up after it dies until it won’t start anymore.
- Pro Tip: Giving the chainsaw a shake or two while it’s idling will help move any leftover gas along.
Clean or Replace the Filter
- Open up the case and check the filter.
- If it looks dirty, clean it gently with a shop towel or brush.
- If it’s damaged or too caked with dust, replace it before starting it back up next season.
- Pro tip: Filters are specific to each engine. If you’re replacing one, make sure it’s the correct filter for your engine.
Clean the Engine
- Clean off the coil fins and any grunge that might be inside the case.
- Pro Tip: A chip brush is the perfect tool for this job.
Remove Bar and Chain
- Open the chain sprocket cover and remove the bar and chain.
- Clean the sprocket and all the grime around it.
- Clean the bar and chain with a biodegradable corrosion inhibitor to keep the chain and bar from rusting. Then reassemble the chainsaw.
Put it to Bed
- Wipe the entire powerhead down, then store it in a dry place out of the reach of children.
- When you need it the following season, fill it with gas and it’s ready to go.
