STIHL recommends using genuine protective equipment designed for chainsaw use. Proper PPE significantly reduces the risk of injury and is essential for safe operation of the chainsaw.
Operating the Chainsaw
Ensure the chain is properly tensioned and the saw is fueled with a correct petrol-oil mix. Start the engine on a flat surface‚ following the manual’s starting procedure. Maintain firm control‚ keeping both hands on the handles. Engage the chain only at full throttle and avoid cutting overhead or in tight spaces. Always monitor your surroundings and keep bystanders at a safe distance. Refer to the manual for detailed operational guidance and safety tips.
Assembly and Preparation
Follow the instruction manual for proper assembly and preparation. Ensure the chain and bar are correctly installed and aligned. Check the chain tension and brake function before use.

Always test the chain brake and throttle response before cutting; Ensure the saw is well-maintained and ready for use. Consult the manual for detailed assembly instructions and preparation guidelines.
Starting the Engine
Before starting the engine‚ ensure the chain brake is engaged. Place the chainsaw on a firm‚ flat surface. Prime the engine by pressing the primer bulb 4-6 times. Move the choke lever to the “start” position. Hold the handle firmly and pull the starter rope with a smooth‚ steady motion until the engine coughs. Reset the choke to the “run” position and pull the starter rope again until the engine starts. Allow the engine to warm up for a few seconds. Disengage the chain brake and test the throttle response. Always follow the manual’s specific starting procedure for the Stihl MS170. Proper starting ensures reliable performance and prevents potential issues.
Basic Cutting Techniques
Always maintain proper posture and grip when cutting. Start with small‚ manageable branches to build confidence. Use a steady‚ controlled motion for straight cuts. For horizontal cuts‚ position the saw at a slight angle to avoid binding. When cutting thicker logs‚ use the “boring” technique: apply light pressure and let the chain do the work. For smaller branches‚ the “snip” method is effective—quick‚ precise cuts with minimal saw movement. Keep the chain sharp and well-lubricated for optimal performance. Avoid overreaching and maintain a clear escape path. Always follow the direction of the wood’s natural fall. Practice these techniques to ensure safe and efficient cutting with your Stihl MS170 chainsaw.
Advanced Cutting Techniques
For advanced cutting‚ master techniques like plunge cutting and angled cuts. Plunge cutting involves inserting the bar vertically into the wood‚ ideal for precise notches. Maintain control by leveraging your body weight and ensuring the chain remains sharp. When making angled cuts‚ align the bar at the desired angle while keeping the saw steady. Use the “pull” technique for smoother cuts by applying gentle pressure. For specialized cuts‚ such as carving or precision trimming‚ slow‚ deliberate movements are essential. Always maintain proper posture and grip to prevent loss of control. Regularly inspect and sharpen the chain for optimal performance. Advanced techniques require practice and patience to achieve professional results safely and efficiently with your Stihl MS170 chainsaw.
Stopping the Engine
To stop the engine of your Stihl MS170 chainsaw‚ follow these steps for safe and proper shutdown. First‚ engage the chain brake to ensure the chain stops moving‚ preventing accidental injury. Next‚ move the master control lever to the “STOP” position‚ which disengages the engine. Finally‚ switch off the ignition to completely power down the saw. Allow the engine to cool slightly before storing or servicing the chainsaw. Always ensure the chain is stationary and the engine is off before leaving the saw unattended. Proper shutdown helps maintain the longevity of your chainsaw and ensures safety.
