The chainsaw therefore runs noticeably smoother. This allows the user to save their strength and work longer.     [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_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_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
