Question about McCulloch Garden

The Chain Tightening Wheel on my chainsaw keeps loosening when cutting so I can only manage one or two cuts before having to tighten. Is there a way of fixing this???

The Chain Tightening Wheel keeps loosening when making cuts due to the vibrations of the engine. This results in only being able to make a couple of cuts before having to tighten; this is very frustrating. Is there a way of solving this???

If this is the tooless adjustment, it sounds like the small gears in the cover have stripped, remove the side cover, turn it over and remove the cover over the tentioning mechanism, replace parts as required.

Tightening chain


Tightening chain is performed by adjusting the bar. Two bolts generally hold the bar in place. Loosen these. Make sure that chain has enough play to easily move by hand. If it sticks, it's too tight. Then tighten the bar, check the chain oil, and cut wood.

Chain tension loosens during use


That is normal after using it. You have to loosen the lug nuts at the bar cover and with the screwdriver end of the tool tighten the screw near the back end of the bar. It is the chain adjustment screw. When tightening it, pull up on the chain with your other gloved hand. Don't over tighten it and tighten the nuts down so the chain will be snug but not too tight.
When sharpening your chain , do not file down the drag links too much. (They do cut better with the drag links filed down just a bit.) But that will also make your chain loosen up more quickly.

What is causing the chain to loosen after little use?


Two things. 1 Make sure the adjustment pin is up against the slot in the bar and 2 Make sure the bare is getting oil. The oil lubricates the chain and cools it down, as the chain cuts it heats up causing the chain to stretch.

Tryed to put on a chain cant get it back togather right


Completely loosen the chain tensioner. When looking at the saw from the sprocket side(bar to the right) the chain WILL travel clockwise. Fit the chain on the bar.(ensure that the chain travels in collation with the sprocket at the end of the bar if equipped). When looking at the saw from the sprocket side(bar to the right) the chain WILL travel clockwise. With the chain still in the bar, fit the 5 or so links in the sprocket on the powerhead, engage the bar with the bar nuts, then lastly engage the chain in the tensioner. Place the sprocket cover and nuts. Tighten nuts then loosen about .5 turn. Adjust chain tensioner. Retighten nuts. See that tightening the nuts made your chain tighter, loosen nuts readjust chain, tighten nuts. With gloves on and the chain brake disengaged please ensure the chain travels around the bar. Put on your chaps and start cutting.

Chain came off a 14 mcculloch how to put back on


Hi, you need to remove the plastic guard on the side, held in place by a nut and a screw. Replace the chain around wheel and chain guard, loosen tightening screw, replace plastic conver, and tighten tightening screw. Make sure you have the chain the right way round, there is usually a small diagram showing this. Hope this helps

Chainsaw chain came off/is loose


You need to tighten the chain, and or remove and reinstall the chain depending on whether or not it has come off the drive wheel. The chain drive is on the right hand side of the saw, and there are either two nuts (about 1/2 inch or 13mm) holding the chain on, or there is a little half round handle you can use to tighten the chain after it is on the drive wheel properly. The saws with the two nuts on them have a small flat blade screw on the backside on the bar that you tighten the chain with. And to make things more confusing, some of the newer bars have a round hole in them, that after you loosen the two bolts, you stick a screwdriver in the hole and turn it clockwise to tighten the bar, then you re tighten the 2 nuts.
Since from your description that it wont engage to cut, you will have to remove and reinstall the chain since it is loose from the drive wheel. Clean out all the wood chips, etc in the drive wheel area before you reinstall the chain, make sure it is not on backwards and sharpen and oil it before you use it. Rick
