Starting a Stihl MS170 chainsaw is a straightforward process. Here is a step-by-step guide on how to start your Stihl MS170 chainsaw: 1. Preparation: - Ensure you are in a well-ventilated area and on a stable surface. - Check that the chain brake is engaged by pulling the chain brake lever towards the front handle. - Set the master control lever to the Cold Start position, which is the first setting on the choke control. 2. Fuel and Oil: - Fill the fuel tank with a mixture of unleaded gasoline and high-quality two-stroke engine oil at the recommended ratio specified in the owner's manual. Usually, a 50:1 ratio is common for Stihl chainsaws. - Make sure the oil reservoir for the chain lubrication is filled with the appropriate bar and chain oil. 3. Starting Procedure: - Place the chainsaw on the ground, ensuring the chain does not come into contact with any objects. - Push the decompression valve (if your chainsaw is equipped with one). The decompression valve reduces the compression during starting, making it easier to pull the starter cord. - With your left hand, hold the front handle of the chainsaw firmly, and place your right foot in the rear handle to stabilize the saw. - Grasp the starter cord handle with your right hand. 4. Starting: - Pull the starter cord slowly until you feel resistance. Then, give a firm, quick pull to start the engine. - Once the engine fires, squeeze the throttle trigger slightly to release the high idle speed setting. - As the engine warms up, move the master control lever to the Half-Throttle position. - After a few moments, move the master control lever to the Run position. 5. Running and Warm-Up: - Allow the engine to warm up for a few moments before starting the cutting operation. - If the engine stalls during warm-up, set the master control lever to the Half-Throttle position and repeat the starting procedure. It's important to note that these instructions are a general guide. Always refer to the specific starting instructions outlined in your Stihl MS170 chainsaw's owner's manual for the most accurate and detailed information. Additionally, ensure you follow all safety precautions, wear appropriate protective gear, and operate the chainsaw responsibly.

It is secured by several screws. - Unscrew the clutch cover screws using a suitable screwdriver or wrench, and carefully remove the clutch cover. 3. Removing the Clutch Drum: - With the clutch cover removed, you will see the clutch drum and the clutch mechanism. - To prevent the clutch drum from rotating, you will need to use a clutch removal tool. - Insert the clutch removal tool into the clutch drum and engage it with the drum's notches or openings. - Rotate the clutch removal tool counterclockwise to loosen the clutch drum. 4. Removing the Clutch: - Once the clutch drum is loose, you can remove it by hand. Carefully slide it off the crankshaft, taking note of the orientation of any washers or spacers that may be present. - Underneath the clutch drum, you will see the clutch itself, which is attached to the crankshaft. 5. Detaching the Clutch: - To detach the clutch from the crankshaft, you will need a clutch removal tool specifically designed for Stihl chainsaws. - Insert the clutch removal tool into the clutch and engage it with the clutch's splines. - Rotate the clutch removal tool counterclockwise to loosen the clutch from the crankshaft. - Once the clutch is loose, you can remove it from the crankshaft by hand. It's worth mentioning that removing the clutch on a chainsaw requires some mechanical knowledge and the right tools.

Installing the New Fuel Filter: - Take the new fuel filter and ensure it is the correct size and type for your Stihl MS170 chainsaw. - If necessary, soak the new fuel filter in fuel for a few minutes to lubricate the rubber gasket and ease installation. - Insert the fuel line into the small hole or nipple on the new fuel filter. Ensure a snug fit. 4. Reassembling and Testing: - Once the new fuel filter is installed, carefully place the fuel line back into the fuel tank. - Ensure the fuel line is properly positioned and secured in the tank, so it does not come loose during operation. - Reattach the fuel tank cap, making sure it is tightened securely. - Reconnect the spark plug wire.
