Saw is brand new so why does the chain keep coming off bar

one trick to use, while you are tightening the chain with the sloted adjuster, pinch the end of the bar and lift upwards. allowing the bar to droop will not get your tentsion correct. Do the chain tensioning with the saw and chain cold. while in use the chain will heat up and become a bit longer, only tighten it again if you have enough slack to see the drive links.

this is a great saw but it comes with a "too narrow" bar that allows the chain to come off the end of the bar too easily. Keep it tight or change the bar to an after market bar and chain. also you will find that the chain drivers get "dinged" pretty bad which makes the chain drag terrible, to fix that problem take off the small aluminum "ell" bar at the bottom of the saw under the chain.

Do not assume that the chain was put on correctly at the factory, mine wasn't and it took me a while to figure out that it was put on backwards - so much for quality control. I would take the chain and bar off and reassemble it. Check to make sure the bar extender pin is in the hole in the bar. Good luck

When the chain is new it tends to stretch as it gets hot. This will require you to adjust the tightness afterabout 15 minutes of use. Make sure you tighten the chain according to the instruction manual, so that youcan only pull it away from the bar no more than the width of the chain. Every chain saw I've owned requires thissame adjustment on a new chain.

I have used this saw a lot with no problems. When I first bought it the blades would fall out occasionally. Now, I firmly push the blade into the slot before closing the blade release lever - no problems. Also be sure you have the correct blade type for this saw. If you do both of those and the problem continues, call DeWalt or bring it to a local service center.

Besides the already mentioned advice the only time I've had the chain slip off was when I twisted it while cutting. Sometimes the angles can get a little awkward or you get a little rushed and you just need to be patient and keep the saw perpendicular to the cut until it's complete. It's only slipped off very few times for me and each time I knew it was my fault and not the saw's. Fortunately it only takes about 5 minutes to reset the chain even if it does slip loose.

If your saw has a sprocket at the tip of the bar it should be no problem, assuming you have experience with a chain saw and know how dangerous they are if not handled properly.

It comes with a bar, and it also specifies which model it fits. You have to get the right pitch for your chain for the saw. You can look it up online to see if it fits it or if there is one that fits. When I bought mine they only had the 3/8 chain.

The saw has a drive belt and I bet yours is a bit stretched. Easy to replace. Check your owners manual for belt replacement - might be on page 37. That should do the trick for you.

I have sometimes problems with that too, that locking mechanism is a weak point of the saw.lubrication does not really do the trick and it attracts dirt, I more than once gave the latch a little love tap with a hammer to loosen it up.

Place the wrench on the stud to determine the direction the direction you need to move it. Then use an old screwdriver against the saw plate to hold the blade as you apply pressure to the wrench. Pushing on the wrench should force the screwdriver shaft against the plate and stop the blade from rotating. Watch out for those saw teeth. I hope your saw works as well as mine, and that I explained this well enough.

Could be the chain brake is on- pull the hand guard to the rear to release. Or the chain is dry of oil & too tight. Or the chain was tossed off the bar and had drive links buggered. Loosen it some, move by hand, and find source of problem. All else fails, read the manual.

I had a similar problem on my Bosch which resulted in me removing the laser from my saw and going back to the stock washer and bolt. Sorry I don't have a better answer; I was not happy with the blade stalling in the middle of cuts and didn't take time to chase the issue.

I had that problem at first. One cause was that I let the jaws close on the branch before starting the saw. I now make sure the chain is not touching the branch when I start the saw. I, also, make sure the chips are knocked off after each cut, blow out any chips in the ventilation area, and visually check the chain isn't loose after each cut. Takes just a second, but haven't had the chain slip off once since I have been doing this.

I'm just guessing, but you may have a problem with the guard on your particular saw. Mine has always woked very smoothly. I use my saw frequently, and am very happy with everything about it.

If the safety handle gets hit and pushed forward (say, from a branch getting in the way), then the saw will stop working. Also, if the chain isn't on tight enough, it will stop working. I find that I have to tighten my chain almost every time I use the saw. Good luck.

You should be able to get a replacement chain at any chain saw repair shop. The bar may have to be ordered from them Worx.

I bwlieve it is due to not having tightened it enough, tho I also believe there is a flaw in design which could help with this. It is VERY frustrating and after the 10th slip and catch, I am ready to send it back.....but when it is going well....what a beauty and so much safer than an elec chain saw or gas one.....

The black knob is a cap that covers a half inch nut that needs to be loosened, then you adjust the chain tension with the screw adjuster next to the bar that you will see if you look at the front of the saw case - right where a normal chain saw adjusts. A medium flat tipped screw driver is used to take up the slack, then tighten the half inch nut back down.. Plug in the saw and run it for a second, then unplug it and check the tension again. If the chain has loosened from where you set it, repeat. Once the slack is out of the saw chain finish tighten the half inch lock nut, and check your bar oil.I personally put the rubber cap away in a drawer so that it wouldn't get lost.
