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

La première fois que j'ai découpé des bois de chauffage avec j'ai été impressionné par la facilité et rapidité pour une tronçonneuse éléctrique. 4 mois après sans l'avoir utilisé, j'ai voulu couper une deuxième volée de bois mais c'était une tout autre histoire. La lame "glissait" sur le bois sans couper. Et quand enfin elle coupait, c'était éxtrément lent et la lame se coinçait dans le bois lors de la coupe. C'est comme si la chaine s'était émoussée en deux utilisations. Les seules raisons que je vois pour ce changement de comportement, c'est que la lame c'est légèrement plié ou que l'huile dans le réservoire n'est pas la bonne (huilde standard pour tronçonneuse de marque Bosch vert). En attendant ça fait cher pour une seule coupe.

Um im heimischen Garten anfallende Holzarbeiten schnell und unkompliziert zu tätigen, wurde diese Akkukettensäge gekauft. Zunächst fällt die noch sehr scharfe Kette auf die, auch aufgrund der hohen Kettengeschwindigkeit, wie durch Butter durch's Holz zieht. Ohne jeglichen Kraftaufwand geht das sägen schnell von der Hand. Sollte das Schnittgut aber doch mal etwas größer und zäher sein braucht es etwas Geduld. Kräftig nachdrücken kann man nicht, da dann der Moter bzw die Akkus schnell überlastet sind und man ne Zwangspause einlegen muss. Die Kettenpannung lässt sich nur mittels Werkzeug einstellen. Dies stört mich jedoch nicht da ich dies von meiner großen Benziner gewohnt bin. Die Schwertlänge finde ich persönlich etwas überdimensioniert da dies eine größere Leistungsfähigkeit suggerieren könnte. Maximal 30cm wären hier eigentlich ausreichend.

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 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.

Ich habe die Säge gekauft, da ich den passenden Akku mit Ladegerät schon hatte. Wie erwartet ist die 1,8KW-Variante sehr stark und entsprechend ist der Akku auch relativ schnell leer. Da ich die Säge nur für Hecken und ein paar Obstbäume nutze reicht das aber völlig aus. Ansonsten hat sie alle Vorteile einer Akkukettensäge: Kein Anwerfen müssen, leise, kein Kabel, kein Benzin/Gestank und ordentlich Durchzug.
