The Stihl MS181 chainsaw is recommended by Masseys for home owner use including chopping fire wood or pruning trees. The chainsaw has a 31.8 cc engine that produces 1.3 kW / 1.8 hp power output and yet it still only weighs 4.3 kg without the bar and chain. The chainsaw sits in the middle of the Stihl petrol chainsaws designed for property maintenance. The MS181 features the environmentally friendly Stihl 2-MIX engine. The Stihl 2-stroke engine with 2-MIX provides plenty of torque and yet save around 20 on fuel compared to standard Stihl 2-stroke engines.

Masseys assemble your chainsaw, PDI it and make sure it is running before you leave the store which will reduce any unwanted down time. Don’t forget, Masseys in Swadlincote, Derbyshire has one of the largest Stihl displays in the UK!

      Stihl Moto mixWe advise STIHL MotoMix® which is Stihl’s patented premixed fuel, specially blended for ultimate performance. Like a sports drink for your engine, this 50:1 mixture is a combination of premium non-ethanol, high-octane motor fuel and our highest-quality STIHL HP Ultra oil. Clean and convenient, MotoMix® eliminates the hassle of mixing your own 2-stroke engine fuel while providing superior performance and lubrication. STIHL MotoMix® contains no ethanol, allowing it to maintain stability for up to two years after the seal is broken – so it stays fresh in your equipment during long storage periods. MotoMix® is also made of non-aromatic fuel and fully synthetic, highly biodegradable engine oil.

The Stihl MS181 in detail:

Advanced combustion technology

Gives lower fuel consumption and high torque across a broad rpm range.

Stihl 2-Mix engine

The chainsaw provides fuel savings of up to 20 percent compared to STIHL two-stroke engines

Anti-Vibration System

A great anti vibration system to help reduce vibrations at the handles.


A Stihl compensator will keep the fuel to air mixture constant even when the air filter starts to deteriorate.

Tool-less filler caps
When out in the field there is no danger of loosing or not be able to refit the fuel cap and the oil cap.

Long-Life air filter system
Ensures that 80 percent of dust particles contained in the sucked in air are caught in the first stage of the system. Unlike traditional systems, these are not collected in the foam filter, but are separated and transported out into the surrounding air. In turn, this provides the elimination of cleaning intervals for the foam pre-filter.

Masseys will assemble you chainsaw, fuel and oil it and give you instruction on how to use your chainsaw. The Stihl MS181 chainsaw is available from Masseys in Swadlincote Derbyshire.



Purchased from Masseys – If your chainsaw was purchased from Masseys and it develops a manufacturing fault during the warranty period, simply return the chainsaw to store and our mechanics will repair the machine free of charge. A warranty repair is when the machine has failed because of improper material or workmanship, under normal use and maintenance.

Purchased online – If you chainsaw was purchased from elsewhere, then we charge an initial £29.99 inspection charge to look at the machine. This will be refunded if the fault is a warranty issue and when the manufacturer has processed and accepted the warranty claim in full. Warranty for non-Masseys customers is 4-12 weeks as we have a duty to ensure our own customers are prioritised first.

Stihl MS181 Chainsaw Advice

Tensioning the saw chain – 

  • Shut off the engine
  • Loosen the side nuts
  • Hold the bar nose up
  • Use a screwdriver to turn the tensioning screw clockwise until the chain fits snugly against the underside of the bar
  • While still holding the bar nose up, tighten down the nuts firmly. Check the nuts are tightened firmly before each use and during operation
  • A new chain has to be retensioned more often than one that has been in use for some time
  • Check chain tension frequently
  • Frequently check side nuts are tightened firmly

Checking the chain tension – 

  • Shut off the engine
  • Wear work gloves to protect your hands
  • The chain must fit snugly against the underside of the bar and it must still be possible to pull the chain along the bar by hand
  • The chain should never be sagging off the bar
  • If necessary, re-tension the chain
  • Check chain tension frequently.
