STIHL MS 251, .325", Guide bar L04, 45cm/18"

Stihl MS 251, .325", Guide bar L04, 45cm/18"

The compact, robust STIHL MS 251 petrol chainsaw is well-suited for both domestic tasks and professional use by skilled tradespeople. Its high cutting performance and durable STIHL .325 RM Pro saw chain make it ideal for efficiently felling and processing even thick tree trunks, particularly when harvesting firewood in the forest.

Powered by a 2.2 kW (3.0 hp) STIHL 2-MIX engine, the MS 251 features a single-lever control that enables one-handed operation of essential functions like starting and stopping. This allows the user to maintain a secure grip on the anti-vibration-equipped handle, protecting their joints and muscles from engine and tool vibrations.

Additional user-friendly features include a tool-free fuel cap and a pre-separation routing system that keeps coarse particles away from the HD2 air filter, ensuring long-lasting engine protection from fine dust. Overall, the STIHL MS 251 is a versatile, high-performance petrol chainsaw well-suited for both domestic and professional applications.

Key Features:

• For domestic users and landscapers
• Durable .325” cutting attachment
• Side-mounted chain tensioning

Features:

HD2-Filter

INCREASES SERVICE LIFE. The HD2 filter protects your power tool’s engine against even the finest dust, ensuring a longer service life and reduced wear. The filter made from PET material has up to 70% finer pores than fleece and polyamide filters, and is also oil- and water-repellent. This also makes it easier to clean the filter. When needed, the filter cartridge can be easily replaced without tools.

Long-life Air Filter System For Chainsaws

EXTENDED FILTER SERVICE LIFE. Pre-separation routing removes coarse, larger particles from the airstream before they can reach the actual filter. The HD2 filter keeps even fine dust away from the engine, ensuring a long engine service life, long cleaning intervals and easy maintenance of your chainsaw. When we refer to a long-life air filter system in chainsaws, this exclusively describes models that have pre-separation routing and an HD2 filter. With this system, you benefit from a significantly longer filter service life compared to conventional air filter systems.

Stihl Anti-vibration System

Intense vibration at the handles of power tools can lead to longer-term effects of blood vessels in the hands and arms. STIHL have therefore developed an effective anti-vibration system where by the oscillations from the machines engine are dampened which significantly reduces vibrations at the handles.

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.

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 Ematic System

REDUCES OIL CONSUMPTION. The STIHL Ematic system comprises a STIHL Ematic or Ematic S guide bar, a STIHL Oilomatic saw chain and a controlled-delivery oil pump. It ensures that the chain oil gets to where it is needed for lubrication. This allows you to reduce oil consumption by up to 50%. If you often work in dusty conditions or if you use long guide bars, you can quickly and easily increase the oil quantity at any time with the new oil pump system.

Tool-free Fuel Cap For Oil And Fuel Tanks

QUICK AND EASY TO USE. With tool-free fuel cap, you can open and close oil and fuel tanks in just a few simple steps, thanks to a bayonet closure.

Stihl 2-MIX Engine

The STIHL 2-MIX engine is both powerful and economical. Separating the exhaust emissions from the unburnt gas minimises scavenging losses, and therefore increases the power output while reducing consumption.

The two-stroke engine with STIHL 2-MIX technology saves up to 20% of fuel and reduces emissions by up to 70% compared to STIHL 2-stroke engines of the same performance class without 2-MIX technology.
