Battery-Powered Chainsaw Ideal For Light Work WOODLOT EQUIPMENT Chain Saws The Oregon PowerNow 40V cordless electric chainsaw makes tree trimming and brush work a breeze Pop in a battery check the oil and start cutting No fuel mixing no pull cord no stalled engine and no hassle
When the manufacturer offered to send one of their new chainsaws to FARM SHOW for testing I jumped at the chance The 14-in bar model I received seemed almost too simple The lithium ion battery pack charged up quickly After adding chainsaw oil I checked its level through the window Once I inserted a battery pack all I had to do was press the trigger release and pull the trigger The cutting chain was at 6 400 rpm’s immediately
Once both battery packs were charged up I headed for the woods The company sent the standard battery pack with listed capacity of 1 25 Ah/47 Wh They also included an endurance battery pack with a 2 4 Ah/89 Wh nominal capacity Both battery packs have a nifty charge check LED panel Press a button and one to four lights show how much charge remains
At just 11 2 lbs with the standard pack and 12 2 lbs with the endurance pack it’s easy to reach up and prune branches I sliced away a variety of smaller stems and branches finishing up with a 5-in dia sapling I ran through the standard battery’s charge and swapped batteries cutting more
I quickly learned to not overload the saw Make it work too hard by pushing down on a large cut and the extra heat load can trip the thermal overload sensor Let the saw pull itself through the wood and that’s not a problem
The chainsaw is equipped with a PowerSharp built-in sharpener see Vol 35 No 1 and I wanted to test it so I wasn’t too careful about digging into the dirt or hitting an occasional stone Once I noticed the saw not pulling itself through the wood I engaged the PowerSharp With the electric motor running full bore I watched sparks fly for about 5 seconds and the saw was back at optimum operation
After more cutting the electric motor ground to a halt The second battery was dead The nice thing is that if you have one last stem to cut or a little more cut to make to drop a sapling wait a few minutes and you’ll get a final burst or two of cutting
Two days later I headed for the woods again with both packs charged This time I was counting Locating a downed poplar I began limbing the tree with the standard battery pack I made about 60 cuts of 2 to 6 in in about 10 min before the battery tuckered out Switching to the endurance pack I made 20 6 to 10-in diameter cuts before running out of juice The company claims the endurance battery pack can cut up to 250 2 to 3-in branches on a single charge
How long the saw will cut on a battery pack depends on how sharp the cutting chain is and how hard the wood is I wouldn’t get this out when I was planning to cut up an oak tree for firewood However I would love to have it around for those quick trimming jobs that are easy to put off for lack of a fresh batch of mixed fuel I’ve spent my time on ladders cutting limbs and this would be a charm for such “less safe” jobs
“For many homeowners it could replace a gas saw entirely ” says David Lofurno Oregon PowerNow Tools “For regular chainsaw users it’s an added tool for occasional work However one landscaper told me he hasn’t used his gas chainsaw for months since getting the PowerNow ”
There are downsides to the electric drive If material is dragged back into the drive sprocket the motor will stop However cleanout is quick Just remember to pop the battery out for safety sake
It’s also important to have a clear bar when starting While the torque is immediate once the motor starts even a small stem against the chain can prevent start-up The easy start could be a concern for anyone with children around Keeping the batteries in a separate cupboard or shelf might be a good idea
The manufacturer’s suggested retail price for the saw kit with the standard battery pack is $399 With the endurance battery pack the price jumps to $499 See the website or call the company for local retailers
