3.1 Starting the Engine
Starting the STIHL FS 70 R engine requires a systematic approach to ensure smooth and safe operation. Begin by priming the engine, which involves pressing the primer bulb 2-3 times to deliver fuel to the carburetor. Next, move the choke lever to the “start” position and grip the handle firmly. Pull the starter rope gently until resistance is felt, then give a sharp, steady pull to engage the engine. Once the engine starts, gradually move the choke to the “run” position. For cold starts, ensure the air filter and spark plug are clean, and use fresh fuel mix as recommended. Always refer to the manual for detailed starting procedures and safety guidelines to avoid complications.
3.2 Cutting Techniques and Best Practices
Effective cutting with the STIHL FS 70 R requires proper technique and adherence to best practices. Hold the trimmer at a slight angle, keeping the cutting head parallel to the ground for even results. Maintain a consistent swath width to avoid overloading the engine, and overlap cuts slightly to ensure thorough trimming. Apply gentle to moderate pressure, as excessive force can damage the machine or surrounding surfaces. Regularly inspect and replace the cutting line to maintain efficiency. For thicker vegetation, use a metal blade attachment for better performance. Always cut in a controlled, sweeping motion, working from one side to the other to achieve uniform results. This method ensures productivity, safety, and longevity of the equipment.
