MS 151 TC-E Petrol Chainsaw: STIHL’s lightest top-handle chainsaw

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.

You can find videos showing you how to fill your machine with fuel and oil, fit bars and chains and start your chainsaw here.

Exterior design of STIHL guide bars are subject to change. Technical specifications remain the same.

Features

The pictures shown are sample photos. The actual appearance of the equipment features and their specific attachment to the product may differ from the pictorial representations, but will have the same functionality.

STIHL ANTI-VIBRATION SYSTEM

FOR MORE PLEASANT WORK. Vibrations can occur when you put your tools through their paces, and these are particularly noticeable in the grip area. The buffer and spring elements of the STIHL anti-vibration system reduce the transmission of engine vibrations to the handle area and therefore to your body. The result is that your tool is more comfortable to hold and your work is much less tiring.

FOLD-OUT HOOK

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.

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.

STIHL 2-MIX ENGINE

HIGHLY POWER-EFFICIENT. With the STIHL 2-MIX engine, you can reduce exhaust emissions and fuel consumption, and therefore operating costs. This 2-stroke engine is low-maintenance and uses fuel efficiently even at high power levels. Use a mixture of petrol and engine oil as fuel. The STIHL 2-MIX engine complies with the strict EU Stage V emissions directive.

STIHL ERGOSTART

EFFORTLESS STARTING. STIHL ErgoStart saves you energy when starting your tools. A smooth and even pull on the starter cord is all that’s needed. The required speed on the starter cord is significantly reduced, and the engine starts quickly and reliably even with a slow pull. An additional spring between the crankshaft and the starter cord roll makes this easier.

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.

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.

SERVICE-FRIENDLY AIR FILTER SYSTEM

The carburetor can be accessed without tools, so you can clean the air filter in a single step.

MANUAL FUEL PUMP

FOR FEWER STARTING STROKES. The manual fuel pump reduces the number of strokes required to start the tool, making the start-up process quicker and easier This is particularly helpful after longer breaks in operation. To use it, actuate the pump several times before starting. This will ensure that there is enough petrol in the carburettor when starting.

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.
