Thanks to its special material, the filter can easily be cleaned by washing, for example with STIHL Varioclean and warm water.     [caption id="attachment_3720" align="alignleft" width="140"] STIHL Anti-vibration System[/caption] STIHL anti-vibration system Precisely calculated buffer zones minimise the transfer of engine and saw chain vibrations to the front and rear handles. The chainsaw therefore runs noticeably smoother. This allows the user to save their strength and work longer.     [caption id="attachment_3724" align="alignleft" width="140"] STIHL ElastoStart[/caption] STIHL ElastoStart Due to compression pressure, jerky stresses occur when starting internal combustion engines. The damping element in the ElastoStart special starter grip alternately absorbs and releases force according to the compression pattern. The result is smooth, even starting.     [caption id="attachment_3723" align="alignleft" width="140"] Decompression valve[/caption] Decompression valve The decompression valve is part of the easy starting system. The valve should be pressed before starting to reduce the compression pressure when starting, as well as reducing the effort needed to pull the starter rope. The decompression valve is semi-automatic; it must be pressed manually before starting, but then closes automatically.     [caption id="attachment_3721" align="alignleft" width="140"] Compensator[/caption] Compensator This controller in the carburettor prevents the fuel-air mixture getting richer as the air filter becomes clogged. The correct quantity of fuel is delivered to the carburettor depending on the quantity of air passing through the air filter. This keeps the fuel/air ratio in the combustion mixture constant and hence also the engine power. The filter doesn't need to be cleaned until an appreciable drop in power occurs.   [caption id="attachment_3725" align="alignleft" width="140"] STIHL Ematic System[/caption] STIHL Ematic System Compared to conventional bars without Ematic, the STIHL Ematic system reduces the consumption of chain lubricant by up to 50 %, depending on the type of wood and the cutting attachment used. This system comprises a STIHL Ematic or Ematic S guide bar, a STIHL Oilomatic saw chain and a variable-flow or reduced-flow oil pump. As a result, virtually every drop of chain lubricant is delivered to exactly the right spot.   [caption id="attachment_3726" align="alignleft" width="140"] QuickStop Chain Brake[/caption] QuickStop Chain Brake The chain brake on your STIHL chainsaw can be triggered automatically or manually. In both cases, the brake band encloses the clutch drum and prevents the chain starting to move even when the throttle trigger is squeezed. The chain brake is applied manually by pressing the front hand guard on your STIHL chainsaw forwards. It is activated automatically whenever a sufficiently strong kickback is encountered.   [caption id="attachment_3727" align="alignleft" width="140"] Side-mounted chain tensioning[/caption] Side-mounted chain tensioning Side-mounted chain tensioning makes it easy to tension the chain safely         [caption id="attachment_3728" align="alignleft" width="140"] Single-lever master control[/caption] Single-lever master control All important functions such as start, choke, throttle and stop are operated via a single lever         [caption id="attachment_3722" align="alignleft" width="140"] Controlled-delivery oil pump[/caption] Controlled-delivery oil pump Different bar lengths, wood types and sawing techniques require different amounts of oil. The controlled-delivery oil pump allows the user to select just the right amount of oil for the job at hand.
