Greenworks GD40CS18 Cordless Chainsaw with Brushless Motor, 40cm Bar Length, 20m/s Chain Speed, 3.81kg, Auto-Oiler, Kickback Protection WITHOUT 40V Battery & Charger

This is a solid unit, but do keep note that it eats through battery, with a chain-speed of 20m/s hardly surprising. Slices through wood like a hot knife through butter, just remember to angle the cut just right to prevent the weight of the branch/trunk crushing back on itself and you'll be slicing like a pro.I felt no kickback, guess this is down to how fast the chain speed is coupled with the low-kickback design of the chain itself.This unit is the tried and tested two bolts plus screw for chain tension design, not really a fan of just turning a knob, prefer old school longevity and reliability. The motor is smooth and though it is not super-quiet, it isn't a mad petrol saw noise, more like a high powered electric trimmer noise, though at around 95db I'd still advise some ear protection if the job is a big one.The oiling works very well. When you put the saw down, you will notice some drops of oil dripping at the handle end, this is completely normal, as this chainsaw likes to well-lubricate the chain, and in doing so it can collect up at the rear over longer durations, best to store the unit upwards so that you don't face a small oily mess in storage, but if you squeeze in a little bit of tissue and wipe what excess oil there is in the frame, then this is a non-issue.I would highly recommend 4ah batteries at the very least if one is going to use this chainsaw for bigger jobs, that is about the only caveat with such a high-power cordless chain-saw. I have tried a dewalt flexvolt equivalent, and that is no where near as powerful as this one, well rated at around 15m/s that would be a given.The chain comes one in a small bag, it is a complete loop, you simply loosen the tension on the saw by turning the screw towards '-' and place chain over the guide-bar (the long bit of the saw) and wrap it around a flange at the handle end which has teeth inside it to grab the chain hooks, then you turn the screw towards '+' to tighten up and then you finally tighten the two bolts on either side of the tension screw to get you that traditional solid fit.Initially as it being a new chain, you will get some slack after running it in with oil in the built-in bottle, and that is when you tighten up the tension a bit as a new chain will loosen up, after that I haven't noticed it needing any further tightening as of yet with over 60 odd cuts, definitely a good chain.Weight wise it isn't light but it isn't particularly heavy neither, it comes to about the same weight as most top-end cordless chainsaws and the balance is quite good from the top handle, remember the top handle is where you control the saw, the rear handle is just for centralising a pivot on the cut, so strong-arm and body to the side when you cut! Keep the motion always to the side of the body with a stiffly held pivot (rear handle), so any kickbacks or swings go down and up clearly away from you, sometimes we get complacent and overly confident, and this is something one should turn into muscle memory with plenty practice before putting such a powertool to good use. Luckily the electric chain brake is instant, fractions of a second I believe, so chances of any serious damage are fairly remote unless your hand remains glued to the button which requires a strong amount of pressure to keep it running.All in all, a great design, well thought out. Now we only just got it so can't speak about longevity as of yet, but based on our other DigiPro brushless Greenworks gear, I have a feeling this one will be with us for many years to come.Oh and did I say it cuts like a laser?! chain-speed is where its at! Most cordless are pushing 11m/s and even then they're over-quoting it... this unit is the real deal, glad they do it at this speed and with the classic two bolt tensioning arrangement. You will notice the other models they do with the knob based tensioning systems barely crack 11m/s... this unit with its 20m/s speed is definitely designed for those who want the closest performance they can get on cordless to high-end petrol saws, 100% highly recommended.ps. was going to do a little video, maybe later when I get someone to hold a camera, but a video doesn't beat practical experience, so if you need one, buy THIS one! I've done the research, nothing out there at this time at this price-point offering what this model offers. Happy shopping all!

I can't praise this enough. My house was hit by a tornado which left a 60 ft cypress tree on the roof but armed with this and a 14 inch greenworks saw I've powered through 3/4 of it. So much safer than corded or petrol Light weight and easy to use it really is wonderful. Buy one you won't be disappointed.

Great tool - I opted for the faster chain speed and longer blade but with hindsight would probably been fine with the shorter blade - preferred over a petrol chainsaw, as is less noisy, easy start and less to worry about fuel mix, but would suggest at least a 4ah battery plus a spare if plan to use it for prolonged cutting - also bought extendable pole saw and both tools proved to be indispensable in clearing a heavily overgrown garden - both do leak a bit of oil when not in use, so judge how much oil you put in - resorted to storing in a plastic bags. No carry case/bag supplied with the chainsaw which although not advertised would have been nice - chain sharpening tools are extra (again would have been nice if included) - I dropped one star for the oil leaking and lack of bag.

I already had two 2Ah batteries from other Greenworks kit. This arrived in a box, not put together. It's not too hard to build, remembering that the chain tensioner needs to go through one of the two holes in the bar. In the field, it cuts really well, although the bigger your battery the better I think.Should also add, they do a 60V version now - I had 40V batteries so went for this one to save money - I think it'll do the job for me.No chain file is included - you'll need to buy one. Also, keep the bag the chain comes in, so you can order new ones.Update 28/10/2023: I've had this for a season now, and it's simply a great chainsaw. I was worried that the chain and bar were a bit too light/thin but they've held up, and I haven't had to change the chain at all yet. It's fast and I get a good lot of wood cut on a single 2Ah battery. I'm mostly cutting hardwood - oak and beech and so on - which I bought for a wood kiln a few years back but didn't use, it's hard but cuts easily with this saw. I would highly recommend.

DONT BUY THIS PRODUCT. VERY POOR PRODUCT. BATTERY LIFE ALMOST JUST 8MIN.CHAINSAW DOES CUT TREE STRAIGHT. SHOCKING QUALITY.

So easy and safe to use and much more gutsy than I expected. Lightweight, quiet. does the job and is eco friendly. Batteries last a decent time and I cut back overhanging trees on my driveway in no time. Delighted!

This was my third Green Works purchase. My lawn mower has just finished its third season, my pole saw and hedge trimmer are on year two.I fear that this purchase has been third time unlucky. The chain wasn't all that easy to fit. It wasn't a good fit on the guide bar. The tensioner didn't retain its adjustment for much more than one attempted cut of a not very big log. The chain then jumped off the guide and ruined itself. My fault, I thought, so I bought new chains. I fitted one along with tensioning problems. It worked for a couple of minutes lost its tension and jammed. Numerous attempts to reseat the chain on the guide and re-tension failed.I, subsequently, read about some substandard guides with a marginally too narrow guide channel. I wonder if my saw was supplied with one of those.I am wondering do I invest in a replacement guide in the hope that the chain will run smoothly or do I return everything for a refund.SORRY Green Works.An ageing muppet here. I was once told when all else fails "read the instructions!".Through my own incompetence and haste to get busy with my saw I managed to chew up several chains needlessly.The chain tensioning should have been obvious. Not as easy as my pole saw but not difficult.Now that I have worked out how to use my saw it's great. So much easier than a petrol engine to start, Try one you will NOT be disappointed.
