MS 172 petrol chainsaw: perfect for processing wood in home gardens
The STIHL MS 172 petrol chainsaw is a powerful petrol chainsaw for homeowners. Whether you are cutting firewood or felling small trees, the MS 172 is an ideal choice that packs plenty of power to get the job done.
Powered by a STIHL 2-MIX engine, the MS 172 has great cutting performance and low fuel consumption. It’s available with a 12” or 14” guide bar and fitted with a 3/8″ P saw chain which has high cutting performance thanks to the narrow kerf. The STIHL anti-vibration system reduces transmission of vibrations to the handle, which relieves strain on your muscles and joints. The MS 172 has single-lever operation and is effortless to restart after interruptions thanks to the combi-lever. It’s also fitted with a transparent fuel and oil tank, so you can clearly see when the chainsaw needs a fuel or oil top up.
Instruction is necessary to recognize or assess the dangers of a chainsaw. Please wear protective clothing and equipment.
You can find videos showing you how to fill your machine with fuel and oil, fit bars and chains and start your chainsaw here.

Features
The pictures shown are sample photos. The actual appearance of the equipment features and their specific attachment to the product may differ from the pictorial representations, but will have the same functionality.
COMBI LEVER WITH STOP FUNCTION
SIMPLIFIED OPERATION. Only one start position is required on the combi lever. Thanks to the stop function, once the machine is turned off the control lever immediately moves back into the operating position. This allows a warm machine to be restarted immediately.
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.
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.
STIHL ANTI-VIBRATION SYSTEM
FOR MORE PLEASANT WORK. Vibrations can occur when you put your 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 tool is more comfortable to hold and your work is much less tiring.
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.
TRANSPARENT OIL TANK
Thanks to the soft grip on the control handle, the chainsaw sits comfortably in the hand and can be operated safely. In addition, the users grip is improved by the soft material, which helps when using the chainsaw in wet conditions.
ADVANCED COMBUSTION TECHNOLOGY
Four overflow channels swirl the fuel-air mix before ignition, allowing for optimum combustion and highly efficient performance. The result is lower fuel consumption and high torque across a broad rpm range.
