Operating the Chainsaw
Start the engine as instructed, then use the throttle and choke controls to adjust power. Apply proper cutting techniques, maintaining control and safety throughout operation. Always follow manual guidelines for efficient and safe use.
4.1. Starting the Engine
To start the engine, ensure the chainsaw is on a flat surface with the chain brake engaged. Wear safety gear, including gloves and protective eyewear. Move the choke to the “start” position, then pull the starter rope firmly until the engine coughs. Release the choke and pull the rope again until the engine runs smoothly. Allow the saw to warm up for a few seconds before cutting. Always follow the manual’s specific starting instructions for the 42cc engine to ensure safe and efficient operation. Proper starting techniques help maintain the chainsaw’s performance and longevity.
4.2. Throttle and Choke Controls
The throttle control regulates the engine’s speed, allowing you to adjust power during cuts. The choke is used primarily for starting and warming up the engine. With the choke in the “start” position, pull the starter rope to initiate the engine. Once the engine coughs, move the choke to the “run” position. For normal operation, the throttle should be used to maintain optimal speed without over-revving. Always refer to the manual for specific guidance on throttle and choke operation for the 42cc engine. Proper use ensures efficient performance and extends the life of the chainsaw.
4.3. Cutting Techniques
For efficient cutting with the Craftsman 18-inch 42cc chainsaw, maintain a firm grip and proper stance. Start with the chain at a 45-degree angle to the material. Apply steady, controlled pressure, allowing the chain to do the work without forcing it. Keep the chain sharp, as dull chains require more force and increase the risk of kickback. When cutting through thicker logs, use a “relief cut” to prevent binding. Always maintain a safe distance from the cutting area and ensure the saw is properly lubricated. Avoid over-revving the engine, as this can reduce control. Follow the manual’s guidelines for optimal cutting performance and safety.
Maintenance and Servicing
Regularly check and maintain chain tension, lubrication levels, and bar condition. Sharpen the chain when necessary for optimal performance. Follow manual guidelines for servicing schedules.

Conduct daily inspections to ensure optimal performance and safety. Check chain tension, lubrication levels, and bar condition. Inspect for wear or damage on chain, bar, and sprocket. Verify proper throttle and choke functionality. Clean or replace air filters as needed. Ensure all bolts and screws are tightened securely. Look for signs of oil or fuel leaks. Test ignition and spark plug operation. Properly lubricate moving parts to prevent friction and overheating. Address any issues promptly to avoid potential malfunctions. Regular maintenance ensures reliable operation and extends the lifespan of your chainsaw.
5.2. Lubrication
Regular lubrication is essential for maintaining your chainsaw’s performance and longevity. Use the recommended 2-cycle engine oil for the motor, following the specified mixing ratio. Apply chain oil to the bar and chain, ensuring even distribution. Properly lubricate the guide bar and sprocket to prevent wear and tear. Always refer to the manual for correct oil types and quantities. Lubrication helps reduce friction, prevents overheating, and ensures smooth operation. Regularly check oil levels and top up as needed. Maintain consistent lubrication schedules to keep your chainsaw running efficiently and effectively. This practice is crucial for preserving engine life and cutting performance.
5.3. Sharpening the Chain
Sharpening the chain is crucial for maintaining cutting efficiency. Use a file or electric sharpener specifically designed for chainsaw chains. Always sharpen in the same direction as the chain’s teeth. Keep the correct angle and depth to avoid damaging the teeth. Sharpening ensures clean cuts and reduces strain on the engine. Regular sharpening extends the chain’s lifespan and improves overall performance. Follow the manufacturer’s guidelines for the recommended angle and frequency of sharpening. Properly sharpened teeth will cut through wood effortlessly, making your tasks more efficient. Always wear protective gloves when handling sharp tools and ensure the chain is securely held during the process.
