Features

Adjustable Automatic Oiler

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.

Anti-Vibration System

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.

Decompression Valve

The decompression valve reduces the compression in the combustion chamber during cranking and helps reduce the effort needed to pull the starter rope.

STIHL ElastoStart™

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.

Fuel and oil caps with retainers

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

Side-Access Chain Tensioner

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.

Wrap Handle (R)

Saw can be used in multiple positions for felling or limbing with hands in the proper positions.

HD2 Air Filter

The new 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.

STIHL OILOMATIC Saw Chain
