## Overview

Designed specifically for homeowners seeking reliable cutting performance without professional-grade complexity, this lightweight chainsaw from Stihl delivers impressive capability in a user-friendly package. Its compact 31.1cc engine generates 1.9 horsepower, providing sufficient power for typical residential tasks like pruning, firewood cutting, and small tree felling. Weighing just 4.7 kg without bar and chain, the MS 172 reduces operator fatigue during extended use sessions.

## Frequently asked questions

### Who is the Stihl MS 172 for?

Stihl lists the MS 172 for homeowners and light duty work. Its 31.1 cc engine produces 1.4 kW, or 1.9 hp, which suits cutting firewood, clearing storm damage and taking down small trees on a property. Continuous professional felling is beyond what a saw of this output is meant to do.

### How much power does the Stihl MS 172 have?

The Stihl MS 172 produces 1.4 kW, equivalent to 1.9 hp, from a 31.1 cc engine. That places it at the light end of petrol chainsaws: enough to pull a chain through limbs and small trunks without complaint, but it will bog down if pushed into hardwood using the full 40.6 cm bar.

### What bar and chain does the Stihl MS 172 run?

The Stihl MS 172 is specified with a 40.6 cm bar and 3/8 inch Picco chain, written 3/8"P. Picco is the narrow, low-profile version of the 3/8 inch pitch, made for smaller engines: it cuts a thinner kerf, so the 1.4 kW motor is not asked to remove more wood than it can.

### How much does the Stihl MS 172 weigh?

The Stihl MS 172 weighs 4.7 kg without bar and chain. Adding the 40.6 cm bar, a chain and a full tank pushes real handling weight higher. Even so, 4.7 kg dry puts it among the lighter petrol saws, which matters most when limbing, with the saw held away from the body.

### What fuel does the Stihl MS 172 take?

The Stihl MS 172 is specified for E-10 fuel, meaning petrol containing no more than 10 percent ethanol. Blends with more ethanol can attack fuel lines and carburettor parts, and fall outside what Stihl specifies for this saw. The manual sets out the oil and mix ratio for its 31.1 cc engine.
