Chainsaw is smoking excessively when in use

It's not bar oil but oil you mix in with your gas. The typical ratio of gas to oil is 40:1. The mix that your using may have excessive oil in it causing it not to completely burn during ignition. It would also cause your exhaust to smoke a lot as well.

You may have the chain tensioner set a little too tight.

Additional things to check:

• The sprocket on the end of the guide bar is greased, and turning smoothly.
• The chain brake is working correctly (not dragging or only partially disengaging).
• The guide bar is straight, not bent or twisted, burr free, and the groove the chain travels in hasn't been squeezed together.
• The chain tension is set correctly.
• The chain oiler is functioning correctly (and you have a sufficient amount and correct type of bar oil).
• Chain is in good condition, and the correct one for the saw. Make sure all of the links flex smoothly.
• Chain is sharp. A dull chain will put more pressure on the guide bar because the cutting teeth aren't digging into the wood efficiently (and usually a person pushes harder on the saw when the chain is getting dull).

if you put the correct chain bar oil in the tank and it is not wetting the bar after a few minutes then take it back or take it to a service dealer and check why
It is not a stream as such as the small amount of oil in the tank will last around 1/2 hour of cutting

Look-up the UT-43103 IPL. There is no provision to adjust the oil flow. Suggest checking the oil lines for loose or broken areas; also could replace the oil pump. These are very inexpensive parts. here is a link to the parts list and source for the parts.

Homelite UT43103 Electric Chain Saw Parts

indicates incorrect length chain in use
the adjustment slots should be about 1/3 when fitted moving close to 1/2 when adjusted
the correct adjustment is when the chain in the center of the bar is lifted up the bottom segments of the chain are still in the bar groove
make sure that the oiler hole is not blocked from saw dust and chips

Hi natcarc2003...
You will use "Bar and Chain Oil",it is used to lube the chain and bar of your chainsaw as you are using it.
You will push down on the top of the oil fill lid to push the oil onto the bar and chain.
It can be bought at any small engine repair shop, WalMart,KMart,HomeDepot,Lowes,etc.
You will fill the reservoir with the oil till it is about 1/2 inch below the surface of the opening of the oil fill on top of the chainsaw.
Please take time to rate me thumbs up

Hi
It's Lisa?
On an electric chainsaw there usually aren't what you would call oiling points.Somewhere,probably on the rear or one side of the case will be a bulb.It's also the screw on cap for the oil reservoir.
You fill that up with chainsaw bar oil,and as you use the saw every few minutes push the bulb down 2-3 times and it applies oil to the chain and gear in the case.The chain transfers the oil to the bar.
If this helps,would you rate my post please?
Thanks Bob
By the way,if you give me your model number I can look for a manual somewhere.No promises though,Ryobi likes to sell their manuals rather than download them.

Hello Andre;
I think you are saying you put oil/fuel mix in the oil tank and bar oil in the fuel tank; discovered your mistake drained both tanks and refilled with the correct fluids. Now the saw runs but smokes excessively. I think it will do no lasting harm. After you have run a few tanks of the correct mix (50:1) through the saw. Remove and clean the muffler and spark arrestor, reinstall them. Inspect your plug if any evidence of fouling replace it. I think you will be cutting with this saw for years.

Yes the additional smoke is caused by a very oil rich mixture and should abate with each fresh tank of fuel. If the chain is not moving ensure the chain brake is not engaged.

If you have more questions or need additional help please reply below and I will get back to you. Good Luck. HTH

Thank You for using FixYa.

As to the proper amount of slack in the chain, new or otherwise, is you should only be able to left the chain from the center of the top bar, so that you can only see the drive tooth of one (1) of the links.

Now with a new chain, the trick is to check the slack after the first tank of gas has been consumed, as new chains tend to "relax/stretch" after being put into service.

But with that being said, I always check the chain at each fueling and filling of the bar lube tank too. Better to be safe and get the maximum performance from your chainsaw, and there is no better way than to keep everything in proper working order.

A good rule of thumb is to:

1. check and readjust/tighten the bar/chain after the fuel tank runs out of gas/oil mix. (wait for the chain/bar to cool before grabbing it with your bare hands!)
2. Refill the bar/chain oil
3. Refuel the chainsaw with the proper gas/oil mix, (typically 40:1)
4. I always add fuel stabilizer to my fuel tank after I'm done using it for the day (who knows when you'll use it again!)
5. Take a hand file and give the cutting chain a quick "touch up" sharpening before putting it away.

If you follow these steps, you'll always have a working chainsaw, ready and sharp enough to cut when you need it, without any surprizes, etc.

I hope you find this Very Helpful and best regards!

change the oil cap put a new one on the problem should go away.
