Sound pressure level dB (A). Sound power level dB (A). Vibration level left / right m / s². 6.9 / 5.6. The newly developed HD2 filter with a polyethylene filter element has 70% smaller pores than nonwovens and polyamide filters, which allows it to effectively filter out even the finest dust.In addition, it has good oil and water repellency and is therefore very easy to clean. Replacing the filter cartridge with PET can be done without the help of special tools. When the engine is started, the decompression valve releases a portion of the compressed mixture from the cylinder. As a result, the required thrust force on the start-up cable is noticeably reduced. It becomes easier for the operator to work, and the entire launch system wears out less intensively. Allows you to accurately dispense oil, depending on the need. A 50 percent reduction in oil supply is possible with an E mark.
With a long saw headset or with very dry wood, it is possible to install additional oil supply (see illustration). STIHL chainsaws with a heated carburetor can be relied on even in winter. In winter mode, the carburetor is blown with heated intake air, which prevents icing.Switching from summer to winter mode is done with one hand movement. QuickStop brake for instant chain stop. The QuickStop chain brake is a protective mechanism when working with chainsaws. The chain brake is activated by pressing the front palm rest and stops the saw chain in a fraction of a second.
With a fairly strong recoil, the QuickStop chain brake works automatically. Strong vibration in the area of the arms can lead to chronic impairment of blood circulation in the hands. Therefore, STIHL has developed a highly effective anti-vibration system (AS). For instruments with AC, the motor vibration transmitted to the handles is markedly reduced. Economical engine STIHL 2-MIX with channel technology "1 in 4" has a high torque in a wide range of revolutions.At the same time, the engine saves up to 20% of fuel compared to two-stroke STIHL engines of similar power without 2-MIX technology. At the same time the volume of exhaust emissions is reduced to 50%.
The STIHL compensator, the regulator in the carburetor, provides almost constant engine power, exhaust quality and fuel consumption for a long time despite increasing pollution of the air filter. Cleaning the air filter is required only with a noticeable drop in power.It becomes possible to work for a long time without maintenance. When replacing the cutting headset, the nuts on the chain sprocket cover can no longer be lost. Machine functions such as cold and hot start, operation and shutdown are controlled by a separate lever.
This makes management particularly convenient and safe, as the right palm remains on the handle. Access to the tensioning screw is provided from the side through the chain sprocket cover. This prevents hands from contacting the sharp chain and the tips of the dog. The STIHL Ematic system consists of an Ematic guide rail, an Oilomatic saw chain and an adjustable feed oil pump. The special design of the tire and chain causes every drop of oil to go exactly where it is required for lubrication.
This reduces oil consumption by 50%. As a result of the pressure of compression at the start of two-stroke engines, jerky forces arise that load muscles and joints. The ElastoStart starter significantly reduces these harmful effects.
The damping element in the handle of the ElastoStart starting device alternately takes over, then gives up energy according to the compression process, and thus the launch occurs evenly, without jolts. Special patented caps for fuel and oil tanks. Tanks, if available, open and close easily, quickly and without tools.
