Good chainsaw for price

6 days ago


Does what you want it to, not the most powerful saw but still cuts through 10inch logs no problems. Did have 1 problem the on off switch stopped working after the 1st use but doesn't bother me ill fix it 1 day but for now I just use the choke to turn it off

What a beauty. If the workers had these saws back in 1969 when we were clearing felling out the back of lake Brunner the NZ Forestry would have bought them by the container load, Best saw I have ever used. No bull.

The chain has come loose after 3 uses.

Reply from Trade Tested

These chainsaws come with a tensioning knob which allows the customer to tension the chain. The customer has managed to tighten the chain back to fit the chainsaw.

Really impressed with my new saw, price was really affordable for me, I didn't expect it to perform as well as it has been, just really wish it came with a self sharpening chain(lol), for price and quality I recommend this chainsaw, remember it's not designed for everyday strenuous use

Quick to set up. Like others have said, instructions are a little hard to understand but easy if you have some knowledge of how things should go together. Have used for about 2 hours total over the last couple of weeks. Have had to tighten chain (usual) and I can feel the chain is blunting already. Chain oil reservoir leaks while not in use (puddle on floor) but otherwise a great unit for the price. Heaps of grunt to get through gum hardwood.

Excellent Value. Price is great and this product has not faulted at all and it certainly is being put through its paces. I purchased this as a once off use as my regular saw (well know brand name) was in for servicing, still have not collected the other saw as this one works better! First time start every time.

This is a great saw, I also bought as a quick replacement but honestly it goes so great just keep using, starts first time without missing a beat. I have been doing some massive jobs with switched the bar to a 16inch set up just to give a bit more grant and 20inch bar was a little excessive, This saw has removed 5 large trees and done a lot of fire wood so far have been working it very hard, a good clean and a sharpen and it ready to go again, i think if you look after with regular cleaning and maintenance it will last a long time and only time will tell....

Zivodevo Auckland

Works great at the start just don't leave fuel in it for the winter

10 months ago


While this worked just great the first summer I used it, when I went to use it this summer, it made a sucking noise and would not start. I traced the problem to a completely perished fuel line hose that is obviously made of cheap rubber. This is a proprietary part that must be ordered in as it has a grommet half-way along the hose that seals the fuel tank.

pretty impressed so far, bought this saw as a backup for my good saw. Because of the price I didn't expect too much and wasn't planning on using all the time but this saw has proven to be the goods. Best feature so far is starting, it hasn't failed to start and I have put about 20 tanks of fuel through it so far. just wont ask it to do to much. appreciate what you paid and give it some respect.

Fantastic Chainsaw

When my old faithful brand name chainsaw died I hesitantly replaced it with the Flash chainsaw thinking it would be a temporary replacement till I found a better option. Well I am amazed just how good this saw is, its easy to start, light to handle and cuts with ease, I have given it a lot of work in the short time I have had it, with out any issues. I will not be looking for another chainsaw this one is all I need, great saw at a fantastic price.

We have a large lifestyle block and it has been in constant use the last month. It can handle the bashing and so far I am stoked. Plastics make it look like cheap, but not worse than what I expected after reading other comments...

Ixion Auckland

Pretty good; very good value

about 1 year ago


Overall, pretty happy. Bit of confusion at the start, the handbook doesn't match the saw, but it all worked out. Very easy to start , can start it one handed when hot . Cuts well , seems to have plenty of grunt. Only downside, is the chain seems to need adjusting a lot , and tends to come off (because of need for adjustment). It can be fine when starting a job, loose by the end. Don't know if that's just a cheap chain, when it wears out I'll replace it with Oregon or similar. Present one cuts OK though, just seems to loosen off real quick. It's not a STihl, but it's not a Stihl price either. I'd say for a home handyman, DIY that needs to deal with reasonably substantial timber, it fits the bill very well indeed. Good value for money

The Trade Tested site was easy to use & the chainsaw arrived within 3 working days. The instructions were Ok, but I found the pictures a bit small & in black and white so you had to use your common sense to work out some of the assembly. Overall I'm happy with the chainsaw & it works well. Trade Tested are very reputable and have others who also vouch for them

Dazzadee Bay of Plenty

Gets the job done

over 2 years ago


Replaced my old smaller saw with this one as had plenty of trees to fell, although the first, being a palm it blunted the chain in one job. The chain tightener screw is not on the side as per manual, but next to the bar at the front and harder to access. Also uses so much bar oil it may not be as economical as my old one. However grunty enough for my purposes and value for money.

Euge Wellington

Little ripper

Bloody ripper of a chainsaw - after getting quotes of $3k+ to fell tree, I purchase this and it handled felling a huge 10m+ Australian eucalyptus tree. Chain was decent, but the file wasnt.

Bevin Auckland

Great liitle starter

over 2 years ago


A positive and responsive starting system. The starter worked well the first and every time. The brake was very efficient too. There is easy access to the shut down system which is a safety feature but means I inadvertently turned it off several times. I am very pleased with this purchase.

Needed to replace my cheap hardware store saw and decided to go with the good reviews of this product. Was pretty easy to put together although I did watch a YouTube video to assist. Used a couple times now and really happy. Cuts easily with no fuss. I’ve been sawing logs into firewood and it makes it a breeze. Highly recommend

Ordering: Piece of cake. Did it on line and only took a few minutes. Delivery: Astounding. I ordered it early on a Thursday morning expecting it to take a few days but it arrived the next day. Starting: Excellent. I followed the starting instructions in the manual and it started perfectly on the second pull. the first pull was with the choke out so you cannot get better than starting immediately with the choke in on the very next pull. Operation: Easily cuts through the hard dry gum that I have and that stuff is very hard on your chain. Reliability: It has started on the second pull every time, except the one time I forgot to turn on the ignition. Didn't even flood it. It has not done a lot of work yet but if it keeps going as good as it has been so far then it is certainly worth 5 stars. Thanks Tradetested. Excellent supplier

Wim Upper Hutt

Flash Chainsaw User experience

over 2 years ago


The chainsaw came 'semi' assembled. The instructions for fulltime assembly are clear and easy to follow. Once ready to use, the saw is a powerful and hard working tool. One point of attention: re-tighten all screws and bolts, as they tend to come loose. (I lost the safety guard bolt). But overall a good buy.

this chain saw has performed so far without any issues after 7 uses, when putting the chain together be careful to remember where the plastic spacer sits, it starts with ease and has plenty of grunt, I am more than happy with the purchase, good quality at a good price, why bother shopping elsewhere, thx

Ambiray Taranaki

Excellent workhorse at an excellent price

over 2 years ago


I bought this chainsaw because my old (famous name) one refused to start despite several firms trying to fix it. The Flash chainsaw starts first time, every time. This is a huge safety benefit - you don't get worn out trying to start it, and you don't have to carry it around with it running. All the functions, including the chain oiler, work just fine. Very good value for money.

Good Chainsaw

Have been able to tackle several large trees on our property ourselves, can use over several hrs. The chain has come off a few times and it does tend to leave oil spots behind on the ground but that could be due to user error. Grunty and reliable.

Used the chainsaw to fell some tree branches, some inawkward positions the Flash performed well. The on off switch does inadvertently turn off occasionally by accident due to it's position.

Wow what a good chainsaw!

I have had an old Stihl and spent some money on it and hardly used it. Came to the point it wasn't worth fixing again. Along comes this Flash chainsaw with case at a bargain price. I initially wondered how it would go when I saw it- the outside casing being plastic and not steel, but gave it a pull and it is reliable, powerful, and well designed with a larger fuel tank than I am used to and a longer bar which is just right.The chain sits still when idling, it cuts down trees superbly the case is super handy also. I definitely recommend this model to all weekend warriors out there.
