STIHL MS 172 Petrol Chainsaw

The MS 172 is one of STIHL’s lighter petrol chainsaws but packs a powerful punch, making it absolutely ideal for homeowners wanting to cut firewood or fell small trees.

Comfortable, reliable and easy to use, this petrol chainsaw is intelligently designed, made from robust materials, and capable of tackling most domestic wood-cutting tasks.

Overview of the STIHL MS 172 Petrol Chainsaw

Weighing roughly 5kg, without fuel but including its bar and chain, the STIHL MS 172 Chainsaw features a fuel-efficient 2-MIX engine and 3/8″ P saw chain, which has a narrow kerf to ensure very precise cutting.

This STIHL chainsaw has an impressive power-to-weight ratio of 3.2 kg/ kW. It is available with either a 30cm (12”) or 35cm (14”) guide bar, so you can match it to your exact cutting requirements.

The MS172 STIHL 2-MIX Engine

Even when used at maximum power, this chainsaw’s 1.9 hp (1.4 kW), low-maintenance 2-MIX engine is completely compliant with the EU’s strict Stage V Emissions Directive. Not only does this make the MS 172 kinder to the environment than most petrol chainsaws, but it also saves you plenty of money on fuel.

(Please note that the STIHL MS 172 Chainsaw runs on a mixture of unleaded fuel and high-quality 2-stroke engine oil. It comes with a recommended oil to fuel ratio of 1:50.)

Advanced Combustion Technology

Four overflow channels swirl the fuel-air mix before ignition to optimise combustion. This results in a high torque across a broad rpm range, lowering fuel consumption and enhancing overall performance.

The STIHL MS 172’s Control Lever

When you stop this petrol chainsaw, the master control lever automatically returns to the operating position. This simplified system allows you to immediately restart the chainsaw, as long as its engine is still warm.

Side-Mounted Chain Tensioning

Thanks to the STIHL MS 172’s side-mounted chain tensioning, you can quickly and safely tighten, loosen or replace the chain, so you won’t need to waste unnecessary time before resuming work.

(Please note that the tensioning screw is horizontally inserted through the sprocket cover.)

Anti-Vibration System for Added Comfort

The MS 172’s buffer and spring elements dampen the engine’s vibrations before they reach the handle, making the chainsaw exceptionally comfortable to use.

Therefore, this anti-vibration system allows you to work far more safely and effectively, particularly on longer jobs.

The Fuel and Oil Tanks

Thanks to their transparent tanks, you can easily monitor the fuel and chain oil levels, without removing the tank caps. Again, this helps you maximise your productivity at work.

When fuel or oil eventually does need adding, the tank caps’ bayonet design makes them easy to open and close, without the need for tools.

A Compensator Means Less Maintenance

The STIHL MS 172’s carburettor is fitted with a compensator. This control system ensures that the engine’s performance, emissions and fuel consumption remain consistent over long periods of time, so you won’t need to worry about cleaning the air filter until there’s a noticeable drop in performance.

STIHL Warranty

STIHL is amongst the world’s oldest and most-trusted manufacturers of handheld power equipment, making it a go-to brand for petrol chainsaws. A reassuring 2-year domestic warranty (or 1-year commercial warranty) is included as standard with this MS 172 model.

Safety Advice

We advise always wearing protective clothing and equipment when operating a chainsaw.
