To start your Stihl 029 or 039 chainsaw, first ensure the chain brake is engaged. Then, set the master control lever to the cold start position. Pull the starter rope until the engine fires briefly, then move the lever to the warm start position and pull again until the engine starts.
The correct fuel mixture for a Stihl 029 or 039 chainsaw is a 50:1 ratio of unleaded gasoline to 2-stroke engine oil. Use high-quality oil specifically designed for air-cooled, 2-stroke engines.
If your Stihl 029 or 039 won't start, check the fuel level and ensure the fuel isn't stale. Inspect the spark plug for fouling or damage and replace if necessary. Also, check the air filter for clogs and clean or replace it.
You should clean the air filter on your Stihl 029 or 039 after every 5 hours of operation or more frequently if operating in dusty conditions. A clean air filter ensures optimal performance and prolongs engine life.
Use a high-quality bar and chain oil specifically designed for chainsaws. This oil provides proper lubrication and reduces wear on the chain and bar.
To sharpen the chain, use a round file of the correct diameter for your chain size. File the cutters at a consistent angle and depth, typically 30 degrees, ensuring all cutters are sharpened evenly.
Regularly inspect the bar for wear and the chain for sharpness. Keep the chain properly tensioned and lubricated. Flip the bar periodically to ensure even wear on both sides.
Common signs include difficulty starting, loss of power, excessive vibration, and unusual noises. Regular maintenance checks can help prevent these issues and maintain performance.
To replace the spark plug, first remove the spark plug boot. Use a spark plug wrench to unscrew the old plug, then install the new plug by hand to avoid cross-threading before tightening with the wrench.
It's recommended to check the air filter, spark plug, and chain tension before each use. Clean the air filter every 5 hours of operation and replace the spark plug annually. Regularly inspect the chain and bar for wear.
