  STIHL 2-MIX ENGINE

  HIGHLY POWER-EFFICIENT. With the STIHL 2-MIX engine, you can reduce exhaust emissions and fuel consumption, and therefore operating costs. This 2-stroke engine is low-maintenance and uses fuel efficiently even at high power levels. Use a mixture of petrol and engine oil as fuel. The STIHL 2-MIX engine complies with the strict EU Stage V emissions directive.

• 

  CARBURETTOR PRE-HEATING

  FOR RELIABLE OPERATION EVEN IN WINTER. Thanks to carburettor preheating, you can work reliably with your chainsaw even in winter. You can change the operation from summer to winter mode in just one simple step. In the winter setting, pre-heated intake air flows around the carburettor, preventing it from icing up.

• 

  SIDE-MOUNTED CHAIN TENSIONING

  FOR SIMPLE AND SECURE RE-TENSIONING. Side-mounted chain tensioning allows for protected, easy and quick chain tensioning and replacement. The tensioning screw is inserted laterally through the sprocket cover.

• 

  COMPENSATOR

  REDUCED MAINTENANCE. The compensator is a control system in the carburettor, which uses pressure compensation to ensure that engine performance, exhaust gas quality and fuel consumption remain virtually constant over a long period of time, despite increasing contamination of the air filter. You do not need to clean the air filter until there is a noticeable drop in performance. This means that you can work for a long time without maintenance.

• 

  STIHL ANTI-VIBRATION SYSTEM

  FOR MORE PLEASANT WORK. Vibrations can occur when you put your power tools through their paces, and these are particularly noticeable in the grip area. The buffer and spring elements of the STIHL anti-vibration system reduce the transmission of engine vibrations to the handle area and therefore to your body. The result is that your power tool is more comfortable to hold and your work is much less tiring.

• 

  Single-lever master control

  All important functions such as start, choke, throttle and stop are operated via a single lever.

• 

  Tool free fuel caps

  Special caps to open and close the tank cap quickly, easily and without tools.

Retrofitted equipment

• 

  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.

• 

  LONG-LIFE AIR FILTER SYSTEM FOR CHAINSAWS

  EXTENDED FILTER SERVICE LIFE. Pre-separation routing removes coarse, larger particles from the airstream before they can reach the actual filter. The HD2 filter keeps even fine dust away from the engine, ensuring a long engine service life, long cleaning intervals and easy maintenance of your chainsaw. When we refer to a long-life air filter system in chainsaws, this exclusively describes models that have pre-separation routing and an HD2 filter. With this system, you benefit from a significantly longer filter service life compared to conventional air filter systems.

• 

  HD2-FILTER

  INCREASES SERVICE LIFE. The HD2 filter protects your power tool’s engine against even the finest dust, ensuring a longer service life and reduced wear. The filter made from PET material has up to 70% finer pores than fleece and polyamide filters, and is also oil- and water-repellent. This also makes it easier to clean the filter. When needed, the filter cartridge can be easily replaced without tools.

    STIHL Smart Connector

    The STIHL Smart Connector forms the basis for using all STIHL connected functions. These functions can be used via both the STIHL connected App and the STIHL connect Portal. Once correctly attached to a STIHL power tool or another manufacturer’s power tool, the STIHL Smart Connector records operational hours while the machine is running, stores them and transmits them to your smartphone via Bluetooth as soon as it is within range. The data received in the STIHL connected App is transferred to the STIHL Cloud when there is an internet connection. The data is stored there in compliance with data protection regulations. The STIHL connected App and STIHL connected Portal allow you to access your power tool data at any time. STIHL connected opens up new avenues for professional users to obtain a convenient and transparent overview of their own power tool fleet. At the same time, STIHL connected provides information including operational hours, power tool status including reminders of overdue maintenance, the last known location, and whether or not the power tools are currently nearby. For professional users, this means improved digital fleet management, more efficient processes within companies, and even closer contact with STIHL dealers. Private users can also use the system to keep an eye on their power tools and carry out maintenance at the right time.
