Stihl MS 172 Chainsaw

STIHL MS 172: The Next-Generation Firewood & Garden Saw

The STIHL MS 172 is the modern benchmark for domestic firewood cutting, garden pruning, and light timber felling. Serving as the upgraded successor to the legendary MS 170, this compact chainsaw pairs a 31.8 cc 2-MIX engine with a high-efficiency 3/8″ Picco Micro saw chain, delivering a 1.4 kW (1.9 HP) output while drastically slashing fuel consumption and emissions. Designed with ergonomic safety in mind, it features an advanced 4-spring anti-vibration array that minimizes hand fatigue, alongside a single-lever master control with an integrated auto-reset stop function so the saw is always ready to restart without flooding. Weighing just 4.5 kg (bare tool), the MS 172 delivers commercial-grade engineering in an accessible package for Irish homeowners and estate managers seeking maximum cutting speed with minimal maintenance downtime.

• STIHL 2-MIX Engine Architecture: Combines strong cutting torque with up to 20% fuel savings and a 70% reduction in exhaust emissions compared to conventional two-stroke engines.

• Single-Lever Combi-Control with Auto-Stop: All essential functions—start, choke, run, and stop—are governed by one master lever. The lever automatically springs back to the operating position after stopping, preventing accidental engine flooding.

• Side-Mounted Chain Tensioner: Adjust the chain tension easily from the side of the housing. This design keeps your hands safely away from the sharp cutter teeth and the spike bumper.

• Ematic™ Controlled Chain Lubrication: The STIHL Ematic system precisely targets bar oil flow to the chain links, reducing bar lubricant consumption by up to 50% while extending the life of your cutting gear.

• Transparent Fuel & Oil Reservoirs: Clear tank windows allow for instant visual checks of your fuel and chain oil levels, eliminating guesswork and preventing unlubricated bar runs.

• Diagnostic Socket Connectivity: Features a built-in diagnostic port allowing authorized service dealers to quickly run electronic health checks, verify operating hours, and troubleshoot ignition data.

• Narrow-Kerf Cutting System: Standard with a 14″ (35 cm) guide bar and narrow-kerf 3/8″ P chain, maximizing engine efficiency by removing less wood per pass for faster cutting speeds.
