  STIHL 2-MIX-Engine

  2-stroke engine with stratified charge. A fuel-free layer of air is created between the burned charge in the combustion chamber and the fresh charge in the crankcase, reducing the amount of fuel lost during the charge cycle. This results in more power with a lower weight, up to 20% lower fuel consumption than regular 2-stroke engines and significantly reduced exhaust emissions.

• 

  STOP BUTTON

  RESTART WORK QUICKLY. With the stop button, you can switch off your power tool quickly and easily for a short break, for example. As the button springs back to its original position after actuation, the engine is immediately ready to start again. This provides more comfort after breaks and increases your work efficiency.

• 

  Multi-function control handle

  Easy, comfortable thumb-operated control means the operator's hand never leaves the handle.

• 

  Manual fuel pump (Purger)

  A small fuel pump delivers fuel to the carburettor at the touch of a button. This reduces the number of starting strokes required following extended breaks in operations.

• 

  Goggles

  It is important to protect your eyes from flying particles and harmful UV radiation. Therefore a pair of safety goggles/glasses are supplied with the the machine. Note: Additional face protection must be worn when working with brushcutters.

  STIHL ErgoStart (FT)

  STIHL ErgoStart cuts the effort required to start the tool by half, while the starter cord can be pulled at just one third of the normal force. A coil spring between the starter cord and the crankshaft smoothes out force peaks, making them virtually undetectable through the cord itself.

• 

  Shoulder strap / carrying system

  Using a STIHL shoulder strap or carrying harness with soft padding makes work more comfortable, particularly during lengthy jobs.

    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.
