The Stihl MS290 is considered an ideal work saw for landowners, and sits firmly in Stihl’s “Farm and Ranch” category. Known as the “Farm Boss” in the United Sates, it was a one-time best-selling chainsaw in the region. It appears that the MS290 first entered the market around 2004. It has since been replaced in the product range by the Stihl MS271 (Farm Boss).
There are nearly 1000 listings on Ebay for MS290 spares and accessories. This is great news for current owners and testament to just how popular this saw was in the day.
Engine spares, whole engines, replacement housings and regular consumables are all widely available to keep your old saw running. If you are considering purchasing a used Stihl MS290 then you can do so safe in the knowledge that there are plenty of spares to fix it up and keep it working.
Weighing 5.9 kg (dry, no bar, no chain) with a 2.8 kW power output from the 56cc engine, this mid-range chain saw should pack enough power to accomplish the various sawing tasks found on gardens, farms, plantations and orchards. Even local authorities might find the MS290 useful for light maintenance work.
The MS290 features a variable-displacement oil pump which precisely controls delivery of lubrication to the chain. The Stihl Ematicâ„¢ chain lubrication system also features which specifically targets lubrication to chain links and guide bar rails. These two features combine in order to dramatically reduce oil consumption by up to 50%.
Stihl have also included a key feature in the carburetor that ensures a consistent air / fuel ratio mixture. The compensator adjusts the quantity of fuel delivered to the carburetor when air flow drops as contamination in the air filter builds up. This system means that the owner has to replace the air filter less frequently. Despite this feature a wise saw owner would replace the air filter more regularly to get the best performance from their machine.
Each Stihl MS290 operator benefits from the designed in anti-vibration system. The system significantly reduces mechanical vibration felt by the operator using the machine.
This feature reduces the likelihood of operators developing Hand-Arm Vibration Syndrome (HAVS) which is also know as Vibration White Finger. This is a very important feature because operators who develop HAVS can suffer a loss of sensitivity in their hands and fingers, pain and reduction in their strength of grip.
