- Engage the chain brake.
- Push the primer bulb several times until fuel is visible.
- Set the choke to the full choke position.
- Place the chainsaw on a firm, flat surface.
- Hold the front handle firmly with one hand and pull the starter cord with the other until the engine attempts to start (pops).
- Move the choke to the half-choke position and pull the starter cord again until the engine starts.
- Once started, allow the engine to warm up briefly before disengaging the chain brake and beginning operation.

Operating Instructions
Before each use, inspect the chainsaw for any damage, loose parts, or leaks. Ensure the chain is sharp and properly tensioned. Always maintain a firm grip with both hands on the handles. When cutting, let the saw do the work; do not force it. Be mindful of kickback and always cut with the lower part of the guide bar. Plan your cuts and escape routes carefully, especially when felling trees.

Maintenance
Regular maintenance is crucial for the longevity and safe operation of your Poulan Pro PR4218 chainsaw. Key maintenance tasks include:
- Chain Sharpening: Keep the saw chain sharp for efficient and safe cutting. Dull chains can cause kickback and strain the engine.
- Bar Oiling: Regularly check and refill the bar oil reservoir. The automatic oiler relies on a sufficient supply of oil to lubricate the bar and chain.
- Air Filter Cleaning: Periodically clean or replace the air filter to ensure proper engine performance and prevent damage.
- Spark Plug Inspection: Inspect and clean the spark plug as needed. Replace if worn or fouled.
- General Cleaning: Keep the chainsaw clean from sawdust and debris, especially around the engine cooling fins and air intake.
