Skogsforum.se/Forestry.com is testing Husqvarna 536 LiXP in thinning work
Is it possible to do thinning with a battery chain saw?
Hi Skogsforum!
It has been a lot af talk about big chain saws for a while
So i thought we should go in another direction today
I have borrowed this one, an electric chainsaw. Husqvarna 536 LiXP
I have never tried a battery saw befor
Neither a chainsaw or a pole saw
I want to try how it works, whats the feeling and is it possible to do real work a full day?
A button to activate the saw
Green light means "ready to use"
Just push the throttle and it runs
You might think a battery saw is silent and that you don't need ear protectives
Bot you do! A saw chain is very noisy
You can't hear it on a normal chain saw where the engine drowns the chain sound.
This is a rather unpleasant sound so: put on your ear protection!
As usual, you need to fill up with chain oil
I will se how it works with the refill. Normally I fill up oil at every gas refuel
Here I probably need to find a new routine. To check if there is oil or not.
So! Battery is charged! Oil is filled up!
Lets go!
This saw has a 12 inch bar and a 3/8 pixel chain, 1,1 mm gauge
Now is the first battery empty
I have worked for about an hour and have cut 40 pieces
Its a mix of pulpwood and firewood
When I look at the inspection window for oil its still some oil left,
Its quite easy to see if there is any oil left
Time for a new battery! Lets refuel!
Battery change in progress
Here we go again with a new battery and oil refilled
Let's go for another hour
I'm working with a professional loggers idea about method....
...but with a slightly overweighted 55 year old guys working capacity.
So it's no problem to wear down the logger with this saw
For sure!
Nice saw to work with!
100% exhaust free
Yepp, there it's finnished. Inexorably!
New battery!
After another hour of work...
So, its time to replace the battery again
It last about an hour and now i have cut mostly spruce
With a lot of delimbing work which consumes battery power
Now at the end i cut birch and that doesn't consume as much power
Then battery last longer and I almost run out of chain oil
I will test another battery
Those three I have used so far have 4,2 Ah power capacity (BLi 150)
These batteries fits very well into the chain saw
Its very well balanced
Its easy to work with and fit well
But here is a larger battery (BLi 300) which gives 9,4 Ah of power
It's heavier and larger. It stands out on each side of the saw.
I will try it and check if it's a different feeling. It should last two times longer
OK, now I will test the larger BLi 300 battery (9,4 Ah and 1,9 kg)
It will not change the performance of the chain saw but it will be interesting to try out the balance
Its heavier and gives the saw some "backweight"
This is the large battery
Of 9,4 Ah
Its a little heavier than the smaller ones but I didn't find it unpleasant to use
I did'n recognize any difference. Actually I did'n notice anything
It last double as long compared with the 4,2 Ah and thats a great benefit in this kind of work
Here is a button for an Eco-Mode
You can hear that it runs a little bit softer but
I didn't recognize any real difference. Maybe when felling but not in delimbing work
One negative thing I noticed is when the saw deactivate itself (to save batteries)
And when you activate again, it doesn't remember it was in Eco-Mode before
So you need to push an extra button every time. Maybe you get used to it, I don't know?
I haven't tested though how much difference in battery consumption the Eco-Mode makes
If it's a difference it will be a benefit as I can't really feel any difference in capacity in this kind of work
Well! Now I have worked some hours
And i have tried out how it is to work with a battery chain saw
And I must say it works very well!
It consumes batteries in this kind of spruce delimbing work, for sure.
I have used appr one battery (4,2 Ah) per hour of forest work
Working a full day, you need five small batteriers (4,2 Ah)
Or three large batteries (9,4 Ah)
I have for sure been warmed up and I have cut some cubic meters of small wood
Some pulpwood and some firewood
This chain saw was a nice acquaintance and I think it performs very well.
Some things are a little new: to remember the check chain oil
It cut's very well. Easy to work with in delimbing work
It sticks some branches and debris in the chain house from time to time
It's a little bit narrow
Especially when delimbing standing small tiny spruce stems
If it's too much it must be removed
It has been interesting. As long as the trees are not to big it works very well.
In felling there is a big difference in power compared with a HVA 550 or another "normal" chain saw
But for delimbing and cutting small trees it works very well. In this case - the chain saw is not the bottle neck!
