The Stihl MSA 120 C-B cordless chainsaw is an exceptionally light cordless chainsaw for garden and property maintenance at home, and for processing horizontal timber.

Quiet and easy to use, it is packed with useful features like the Quick Chain Tensioning so you can tighten the chain without tools, the Ematic chain lubrication system which uses up to 50% less chain oil and the QuickStop Super chain brake.

It has outstanding cutting performance and low vibrations, as well as an impressive <40 minutes of battery life on the recommended battery, which will give you around 120 cuts in 10 x 10cm timber.

Run Times

  • Run time on AK 20 battery: Up to 40 minutes
  • Run time on AK 30 battery: Up to 55 minutes

Quiet operation
The STIHL COMPACT cordless power system devices are so quiet you don’t even need ear protection.

STIHL Chain Quick Tensioning (B)
The STIHL chain quick tensioning system (B) makes it very easy to tension the chain. Just release the sprocket cover and turn the knob to set the optimum tension. No tools needed.

QuickStop Super Chain Brake (Q)
The additional braking system for extra safety. Users can trigger the chain brake directly at the rear handle. The chain stops in seconds whenever the user lets go of the rear handle and whenever there is sufficiently strong kickback or when the front hand guard is activated. This unique safety feature ensures even more user protection in all working positions.

Intermediate battery position in the device
The battery can be inserted into the device in 2 stages. In the first locking stage – the intermediate position – the battery is secured in the device but does not touch the contacts in the device. In the second locking stage – the operating position – the battery is completely inserted and touches the contacts in the device.

Toolless filler cap
The tank can be filled quickly and easily using the toolless filler cap.

Control handle
The soft black component on the rear control handle ensure a safe and secure grip in any situation. The control lever must be released using the lock button on the side.

STIHL Electric Motor (EC)
The STIHL electric motor (EC) is extremely energy efficient, lightweight and compact. It runs quietly, generates very low vibrations and does not require servicing.

STIHL Ematic System
Compared to conventional bars without Ematic, the STIHL Ematic system reduces the consumption of chain lubricant by up to 50 %, depending on the type of wood and the cutting attachment used. This system comprises a STIHL Ematic or Ematic S guide bar, a STIHL Oilomatic saw chain and a variable-flow or reduced-flow oil pump. As a result, virtually every drop of chain lubricant is delivered to exactly the right spot.

Two-handled operation
The ergonomically shaped handle and rear control handle with comfortable soft-grip component ensure safe working in all operating positions.

    Bought this chainsaw as it had a good review in ‘Which’. It is very light and easy to use, and although not as versatile as a big (heavier) model, it has done everything I’ve asked it to! Two tradesmen, who both scoffed when they saw (no pun intended) it, saying it would be useless and was just a toy, had to eat their words and were full of praise after they’d used it. Expensive? Yes – I thought so until I got it – now it seems like a bargain! Especially recommended for women. . . .

    I have two Stihl petrol chainsaws but in an urban environment they are noisy and intrusive. The cordless Stihl MSA120C is perfect for those small jobs around the garden without disturbing the neighbours. I also own the Stihl leaf blower which uses the same battery so I bought two batteries and and can be charging one while using the other in blower or chainsaw.
    Like all Stihl products this is well made and I hope it will be reliable.

    Brilliant chainsaw! Ideal for beginner, but my very experienced instructor now wants one too. Great value from Radmore and Tucker :)

  4. Neil Fray (verified owner)

    Wasn’t sure at first, but this is a brilliant piece of kit.

  5. Tom Logan (verified owner)

    light easy for me to carry in a back pack micro chain cuts like nothing I’ve ever seen! I love this saw

  6. Lin Gilbert (verified owner)

    I am delighted with this saw. It is easy to use, highly efficient and not too heavy. I have used both electric and petrol chainsaws and this is equal to, if not better than both.
    Delivery was very quick and I was kept informed every step of the way.

  7. Diana Mackintosh (verified owner)

    Excellent little chainsaw to replace a larger petrol one. it does the job as well and is lighter to use, no smell, hardly any noise. Recommended.

  8. Mike Bedford

    My old petrol chainsaw gave up the ghost and decided to give this a try. What a revelation – the chain is incredibly sharp and coupled with the power it sliced through 30 logs in no time at all. I think it was going for about 30-40 minutes and when finished it still had ~15-20% power left. Nice and light and easy to hold steady, immediate start up with no priming/stalling/fumes and noise, I’d go for this and another battery over a petrol anytime

  9. Paul (verified owner)

    Excellent product. Nicely made, great balance, extremely effective, quiet in use. Battery lasted long enough to cut up 4 bags of logs which is pretty reasonable. Sawed through a 12 inch log with ease.

  10. Diana Bray (verified owner)

    I have been absolutely blown away by how brilliant this chainsaw is. We have a small petrol husquavana chain saw which is brilliant but it’s noisy and I find its too heavy for me to use after a short while, and certainly too heavy to use for tidying up the cut branches and I hate the half an hour of faff every time we go to use it, and needing spanners to tighten the chain etc.
    The battery powered Stihl MSA 120C far exceeded my expectations in all respects. I used it tidying up the branches and cutting logs from them. It kept on going and going and I had run out of steam by the time the battery got down to one star – so I kept cutting logs from the branches until the battery had enough. The thickest was about 6 or 8 inches diameter and mostly 4 inches.
    What you don’t think about is that unlike a petrol chainsaw, when you are not cutting, it is switched off – so that 50 mins of battery life lasted over 2 hours tree work and I never used my second battery. I topped up my chain oil about every 40 mins and used about 300ml of chain oil in about 2.5 hrs, so do keep checking and topping up the oil.
    I loved that I didn’t need to use a screwdriver or tool to use it (except for a toothbrush to clean up). I assembled it myself and that needed a screwdriver to fit one screw! Easy!
    I’m 57 next month and averagely fit and strong – my husband can use the husqui if he wants to, but this is the machine for me – and he was stunned how good it was too.
    I already have a lawnmower and hedge trimmer that use the same batteries, so for me this was a good value purchase too. And Radmore and Tucker are excellent and have great prices too!

    I was planning to write, but you beat me to it.
    I’m delighted with the Stihl cordless chainsaw. It is light and effortless to use, even with one hand (don’t tell anyone I said that!). It is a quality product. It has made lockdown a pleasure.
    And, the service you provided in these difficult times was outstanding, barely a couple of days from order to delivery.
    Thank you so much – exemplary.

  12. Konstantin (verified owner)

    It is a great product and a very useful for occasional jobs about my garden. We have a lot of trees, so I found Stihl MSA120C cordless chainsaw a very handy indeed. When I was choosing the model, I went for an “additional battery + charger” option, which I found a perfect solution for amount of work I need to undertake daily. The productivity rate has increased significantly, as two charged batteries could last much longer. The weight of this chainsaw is just right and feels correct and comfortable to work with.
    The service and delivery have been provided in a very professional fashion. Overall a 6* experience!

  13. Roger Williams (verified owner)

    Marvellous bit of kit. Sceptical at first, this little saw was going through 8 inch ash with ease as an experiment. Had my trusty Husqvarna 254 XP with me cutting all the big stuff, but how much easier it was on my back going through a lot of smaller branches ( 4inch) with the Stihl 120. Wish I had bought one years ago !.

  14. Colin (verified owner)

    Ordered the Stihl MSA120 chain saw. It arrived within the stated delivery time in perfect condition. A great saw for what I needed around my land. Very happy with Radmore & Tucker service.

  15. Christopher Balcomb (verified owner)

    An excellent small chain saw that does an amazing job for such a small unit. The battery holds up well. Radmore and Tucker is one of the few businesses that manages to get everything right. Ordering, delivery, price, all faultless. I’ve bought from them before and have always had the same high standard, including helpful advice when needed.

  16. Diane Cox (verified owner)

    Bought this for my husband as a treat and a bit of fun, and he is over the moon with it, he has petrol and an electric chainsaws, but this is ideal for small or awkward jobs in hard to reach places as it is lightweight and no lead to get in the way. Smashing tool at a smashing price, plus excellent service arrived in two days brilliant. Thank you.

  17. Michael Wilson (verified owner)

    Very simple to put together and surprisingly powerful cutting action. I do have a Stihl petrol chainsaw which is a terrific bit of kit but this will be great to use when I have a few minutes available and I want to cut up a few fire logs. I tried this on logs of different diameters and found it was pretty comfortably dealing with 6 inch thicknesses.
    All in all very happy and I now have another use for the Stihl battery and charger which accompanied my purchase of a cordless strimmer. Very impressed with the quick delivery to the “wilds” of Cheshire!!
