The Stihl 290 chainsaw is a popular choice among both professional loggers and homeowners looking for a reliable tool to handle cutting and felling tasks. In this article, we’ll provide a concise and clear technical overview of the Stihl 290 chainsaw, suitable for both technical and non-technical audiences.
Engine Specifications
The Stihl 290 chainsaw is equipped with a powerful two-stroke engine known for its durability and performance. Key engine specifications include:
Displacement: The engine has a displacement of 56.5 cc, which is a measure of the engine’s size and power output. A larger displacement typically results in more cutting power.
Power Output: The Stihl 290 chainsaw delivers around 3.8 kW (5.1 hp) of power, making it well-suited for a wide range of cutting tasks.
Fuel Mixture: Like most two-stroke engines, the Stihl 290 requires a specific fuel mixture of unleaded gasoline and two-stroke engine oil. It’s crucial to follow the manufacturer’s recommendations for the correct fuel-oil ratio.
Bar and Chain
The chainsaw’s cutting performance heavily relies on its bar and chain specifications:
Bar Length: The Stihl 290 is available with different bar lengths, typically ranging from 16 to 20 inches. The choice of bar length depends on the type of cutting you plan to do. Longer bars are suitable for larger trees and thicker branches.
Chain Pitch and Gauge: The chain’s pitch and gauge determine its compatibility with the bar. The Stihl 290 chainsaw usually uses a 3/8-inch pitch chain with a 0.063-inch gauge. Different chain types are available for various cutting conditions.
Weight and Ergonomics
Considering the weight and ergonomics of a chainsaw is crucial for user comfort and control:
Dry Weight: The Stihl 290 chainsaw weighs around 13 pounds (5.9 kg) without the bar and chain. This weight is manageable for most users but may become tiring during extended use.
Ergonomic Design: Stihl chainsaws are designed with user comfort in mind. They feature anti-vibration systems and ergonomic handles to reduce operator fatigue during long cutting sessions.
Starting Mechanism

To keep your Stihl 290 chainsaw in optimal condition, regular maintenance is essential:
Chain Tension: Proper chain tension is crucial for cutting performance and safety. Check and adjust the chain tension regularly to prevent it from slipping off the bar.
Air Filter: Keep the air filter clean to ensure the engine receives a proper air supply for combustion.
Bar and Chain Maintenance: Lubricate the bar and chain regularly to reduce friction and extend their lifespan.
Spark Plug: Check and replace the spark plug as needed for reliable engine ignition.
