The decompression valve temporarily reduces the compression in the combustion chamber during cranking and helps reduce the effort needed to pull the starter rope, it is opened manually and closes automatically as soon as the engine fires

The fuel and oil cap retainers keep the caps attached to the unit for added convenience

The Adjustable Automatic Oiler allows the user to adjust the lubricant of the guide bar and saw chain for different bar lengths and cutting conditions

The side-access chain tensioner makes it much more convenient for the user to adjust the saw chain with a bar wrench as opposed to the typical location of the guide bar adjustment screw

STIHL has developed a system for minimizing the vibration levels of handheld outdoor power equipment, the STIHL anti-vibration system helps reduce operator fatigue and provides a more comfortable working experience

The ElastoStart starter handle is an exclusive feature of STIHL, it is a starting grip with a built-in shock absorber that helps reduce the effort when pulling on the starter cord

The ElastoStart starter grip noticeably reduces the sudden peak forces (compression) normally felt during cranking, the forces which occur at the grip after the first compression stroke are smoothed out

The HD2 air filter on this unit is washable, providing extremely long filter life and lowering maintenance costs

The large surface area allows for longer run times between cleanings and high performance even while operating in dusty and dry conditions, overall the HD2 air filter provides better protection of the engine compared to standard air filters

The decompression valve, also referred to as ‘deco’ or ‘deco valve’, vents compression in the cylinder for easier starting
