Chain stops when it touchs log - McCulloch 10" Electric Pole / Chain Saw

Hi Pam:
Using chain saws takes a bit of getting used to, and it can be DANGEROUS.
- The chain must be sharp to be able to cut properly, and a sharp chain "bites" into the wood.
- Before you touch the chain into the wood, you have to speed up the engine. This takes some getting used to.
- Try this technique: With the chain about an inch above where you want to cut, squeeze the throttle about half way so the chain is spinning. Touch the chain to the wood and increase the engine speed as the chain starts to cut. The harder you cut, the more power you need to apply.
After a while it gets to be second nature.
Work Safe, and get an experienced friend to help with some "hands on" coaching.
Cheers.

Check and be sure you didn't install it backwards.

I will need more information. Will the chain stop if touched to a log? Is it just creeping along compared to the speed of the motor or matching the speed of the motor? Has the saw been used enough to have saw dust build up inside the clutch and keep it engaged?

may have it too tight or my other main guess your clutch is out

hi there , i would say this as advice , it looks like the chain is gone blunt you either need to get a sharpening tool or a new chain , also keep checking the oil levels as some harder woods spend more oil



please rate this if found useful , many thanks it only takes 1 second

Remove the clutch cover, bar, and chain. Wash out the interior of the clutch with spray carburetor cleaner to get rid of oil build-up. Reinstall the bar, chain, and cover after cleaning the bar drive-end small oil passages that run out to the chain groove. Adjust the chain up to the bar, but not so tight that you can't move the chain by hand. Hope this helps!

The most likely cause is a loose chain.
Chain Adjustment

1. Make sure the chain brake is off (gloves will protest your fingers).
2. If necessary, loosen the bar nuts that are clamping the clutch cover in place (or whatever holds the clutch cover and bar on). They do not need these really loose - finger tight will do.
3. Ease the tension adjustment until the chain is obviously loose.
4. Using one hand, hold the nose of the bar up.
5. While holding the nose up, adjust the tensioner so that the center of the chain just touches the underside of the bar, add a touch more.
6. Continue holding the nose of the bar up & tighten up the bar nuts / bolts / quick-release system.

chain is too tight on the bar or is lacking lubrication oil. loosen up the bar nuts and back off the chain tensioning screw a touch. make sure the bar oil reservoir is full and the chain is receiving oil when its running.

If your saw has a removable sprocket, Check the drive sprocket on the clutch drum. Either the the spline is worn or the drive link on the chain is not properly seated in the sprocket well.
