Wipe up any spills immediately and securely replace the fuel cap. Never smoke while fueling.

Starting the Chainsaw

Before starting, ensure the chain brake is engaged and the chainsaw is placed on a firm, level surface. Follow the cold start procedure by setting the choke, priming the fuel bulb, and pulling the starter cord firmly. For a warm start, disengage the choke.

Never attempt to drop or throw start the chainsaw; this is extremely dangerous.

Cold Start Procedure

Begin by engaging the chain brake for safety. Set the choke lever to the “full choke” position. Prime the fuel bulb approximately six to ten times until fuel is visible. Position your foot firmly on the rear handle and grasp the starter handle. Pull the starter cord with a smooth, firm motion.

Repeat until the engine starts, then disengage the choke.

Warm Start Procedure

Ensure the chain brake is engaged for safety. With a warm engine, set the choke lever to the “half choke” or open position. Prime the fuel bulb a few times – typically three to five pumps are sufficient. Firmly plant your foot on the rear handle and grip the starter handle securely.

Pull the starter cord smoothly until the engine restarts.

Operating Instructions

Always maintain a firm grip with both hands while operating the Poulan Pro PR4218. Be acutely aware of kickback potential, a dangerous reaction that can occur when the guide bar’s tip contacts an object. Employ proper cutting techniques, avoiding plunging cuts.

Ensure a clear work area, free from obstructions, and always plan your escape route. Never overreach or cut above shoulder height for optimal control and safety.

Proper Cutting Techniques

When using the Poulan Pro PR4218, utilize a firm stance and maintain a secure grip. Begin by opening the cut with a controlled plunge, then utilize the saw’s weight to assist in the cutting process. Avoid forcing the blade, letting the chain do the work.

Always plan your felling direction and be mindful of branches that may spring back. Use bore-cutting for limbing, and avoid twisting the bar within the cut.

Avoiding Kickback

Kickback, a sudden, forceful upward or backward motion, is dangerous. To minimize risk with your Poulan Pro PR4218, avoid contact between the guide bar’s upper quadrant and any object. Maintain a firm grip with both hands, and never overreach.

Always keep the chain properly sharpened and tensioned. Be acutely aware of the bar’s position during cutting, and never cut above shoulder height.

Chain Sharpening and Maintenance

Maintaining a sharp chain is crucial for safe and efficient operation of your Poulan Pro PR4218. Regularly sharpen the chain to ensure clean cuts and reduce strain on the engine; Inspect the chain for damage, replacing it if necessary.

Consistent sharpening and proper tension contribute to optimal performance and minimize the risk of kickback. Refer to the manual for detailed sharpening instructions and tensioning guidelines.

Sharpening the Chain

To sharpen the chain, use a round file of the correct size, guided by a sharpening tool. Maintain the correct filing angle, ensuring each tooth is sharpened uniformly. File from the inside of the tooth outward, using smooth, consistent strokes.

Check the depth gauges and file them down if needed, maintaining proper height for optimal cutting performance. A properly sharpened chain significantly improves cutting efficiency and safety.

Checking Chain Tension

Proper chain tension is crucial for safe and efficient operation. With the engine off, pull the chain away from the bar; it should lift slightly, approximately 1/8 inch. Adjust tension using the tensioning screw, ensuring the chain moves freely around the bar.

Regularly check tension, especially during initial use, as a new chain stretches. Incorrect tension can lead to derailment or damage to the chainsaw.

Bar Maintenance and Care

Regular bar maintenance extends its lifespan and ensures optimal cutting performance. Frequently clean the bar with a soft cloth, removing sawdust and debris after each use. Inspect the bar rails for wear and burrs; file them smooth if necessary.

Maintain proper lubrication and periodically check for bending or damage. A well-maintained bar contributes significantly to chainsaw safety and efficiency.

Cleaning the Bar

Regularly cleaning the chainsaw bar is crucial for smooth operation and longevity. After each use, utilize a soft cloth to meticulously remove accumulated sawdust, pitch, and wood debris. Pay close attention to the bar’s groove, ensuring it remains free from obstructions.

A clean bar facilitates proper chain lubrication and reduces wear, contributing to efficient cutting and overall chainsaw health.

Bar Rail Maintenance

Maintaining the bar rails is essential for optimal chainsaw performance. Regularly inspect the rails for burrs or damage, as these can cause chain binding and increased wear. Use a flat file to carefully remove any burrs, ensuring smooth, even rails.

Properly maintained rails promote efficient chain travel, reducing friction and extending both bar and chain life, ultimately improving cutting efficiency.

Troubleshooting Common Issues

Encountering problems? If your chainsaw won’t start, check fuel levels, spark plug condition, and ensure the chain brake is disengaged. A chain running at idle often indicates carburetor issues; refer to the carburetor adjustment section.

Avoid attempting unsafe starting methods like dropping or throwing the chainsaw. Always consult this manual for detailed solutions before seeking professional repair services.

Chainsaw Won’t Start

If the engine fails to ignite, first verify adequate fuel in the tank and a proper 50:1 fuel mixture. Inspect the spark plug for fouling or damage, cleaning or replacing it as needed. Ensure the chain brake is fully disengaged.

Confirm proper flooding isn’t occurring; excessive fuel can hinder starting. Consult the carburetor adjustment section if issues persist.

Chain Runs at Idle

If the chain unexpectedly moves when the engine is idling, immediately stop the chainsaw and disconnect the spark plug wire for safety. This indicates a carburetor issue requiring adjustment. Refer to the CARBURETOR ADJUSTMENT section within this manual for detailed instructions.

Do not attempt to throw or drop-start the chainsaw, as this is extremely dangerous and can cause severe injury.

Carburetor Adjustment

Proper carburetor adjustment is crucial for optimal engine performance. All repairs and adjustments not detailed in the Operator’s Manual must be performed by qualified service personnel. Adjustments impact idle speed and mixture, affecting cutting efficiency and fuel consumption.

Consult the manual for specific procedures regarding adjusting the carburetor and achieving the correct idle speed for your Poulan Pro PR4218 chainsaw.

Adjusting the Carburetor

Carburetor adjustment impacts engine performance, requiring qualified personnel for repairs beyond the Operator’s Manual. Fine-tuning ensures efficient cutting and fuel use. Improper settings can cause starting issues or poor operation. Refer to the manual for detailed steps.

Adjustments affect the air-fuel mixture, influencing idle speed and overall responsiveness. Precise calibration is vital for optimal chainsaw functionality and longevity.
