The lightest top handle saw made by STIHL.
This upgraded version of the MS 151 features a new 2-MIX engine that consists of a new cylinder, piston and exhaust. These changes mean there is an increase in power of the saw by up to 1.05 kW and a 15% increase in torque to 1.1 Nm – all while retaining the lightweight nature of the saw.
Fitted with a manual fuel pump and STIHL’s ErgoStart (E) technology, this saw is easy to start-up so you can get on with the job straight away.
STIHL ErgoStart (E)
A genuine advance in easy starting. STIHL ErgoStart (E) cuts the effort required to start the tool by half, while the starter cord can be pulled at just one third of the normal force. All it takes is 2 fingers and a gentle pull action.
1-in-4 channel technology. The economical STIHL 2-MIX engine with 1-in-4channel technology features a high torque over a wide speed range. The chainsaw provides fuel savings of up to 20% compared to STIHL two-stroke engines in the same performance class without 2-MIX technology. Exhaust emissions are reduced by up to 50%.
Manual fuel pump (Purger)
A small fuel pump delivers fuel to the carburettor at the touch of a button. This reduces the number of starting strokes required following extended breaks in operations.
Side chain tensioner
The tensioning screw can be found on the side of the chain saw through the sprocket cover. This removes the need for contact with the sharp saw chain.
Tool free filler caps
Special catches on the fuel and oil tanks for easy opening and locking without the need for tools.
Service-friendly air filter system
The carburetor can be accessed without tools, so you can clean the air filter in a single step.
Intense vibration at the handles of power tools can lead to long-term effects on blood vessels in the hands and arms. STIHL has therefore developed an effective anti-vibration system whereby the oscillations from the machine’s engine are dampened which significantly reduces vibrations at the handles
The fold-out hook serves as a carrying rope attachment for lowering the arborist saw and for security. When it is pushed in, the hook doesn’t get in the way of your work or when it’s in storage.
This controller in the carburettor prevents the fuel-air mixture getting richer as the air filter becomes clogged. The correct quantity of fuel is delivered to the carburettor depending on the quantity of air passing through the air filter. This keeps the fuel/air ratio in the combustion mixture constant and hence also the engine power. The filter doesn’t need to be cleaned until an appreciable drop in power occurs.
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.
