STIHL - 1146-200-0055 - Petrol Chainsaw Ultralight MS 151 C-E 1.5 hp

The lightest STIHL petrol chainsaw for preparing firewood and for tree care and small thinnings. Ergonomic and easy to operate. Comfortable starting thanks to the manual fuel pump and the STIHL ErgoStart system. Narrow kerf and easy guiding thanks to the use of the PM3 1/4" saw chain. With the economical 2-MIX engine. The STIHL 2-stroke engine with 2-MIX technology provides high power while saving fuel consumption by up to 20% compared to 2-stroke STIHL engines of similar power without 2-MIX technology. Exhaust emissions drop by approx. 50%. Manual fuel pump The manual fuel pump allows fuel to be delivered to the carburettor by pressing a button. This reduces the number of starter rope pulls needed to start the device after a longer standstill. Easy-to-use filter system Tool-free removal of the carburettor cover enables the filter to be cleaned in one grip. STIHL ErgoStart (E) A spring placed between the starter rope pulley and the crankshaft compensates for load peaks on the starter rope, making them almost imperceptible to the operator. Result: Compared to conventional starting systems, the STIHL ErgoStart system halves the force required to start the device and enables the starting speed to be reduced by about two thirds. STIHL four-channel technology In the four transfer channels, the fuel-air mixture is swirled before ignition. This ensures better fuel combustion and significantly increases engine efficiency. Effect: lower fuel consumption and high torque over a wide speed range. Anti-vibration system Strong vibrations transmitted through the handles of mechanical devices can lead to vibration disease. For this reason, STIHL developed the anti-vibration system. In mechanical devices equipped with the AV system, the handle zones significantly reduce the number of vibrations generated by the combustion engine and the working tool. Filter cleaning only becomes necessary when the engine power noticeably drops. The STIHL compensator located in the carburettor ensures that despite increasing contamination of the air filter, engine power, harmful substance content in the exhaust and fuel consumption remain constant for a longer period. This allows longer operation without the need for maintenance work. Side chain tensioner The tensioning screw is turned with a special knob passing through the sprocket cover of the saw chain. This avoids hand contact with the sharp saw chain and the teeth of the bumper spike. Practical tank cap Special, patented fuel and oil tank caps. Tanks of mechanical devices equipped with such caps can be opened and closed quickly - without force and without any tools.
