McMulloch EM250 motor spins but the chain does not move

The motor spins but the chain does not move on my McMulloch EM250 Electramac chain saw. If I drag the chain a bit, then it engages and runs. Can anyone point me to a parts break-down drawing?

    I experienced the problem the last time I used it. I lifted on the chain to check to see how tight it was and could see most of the drive link, so I tightened it a bit. The problem did not go away. Perhaps there is a clutch between the motor and the drive gear? The saw has seen only sporadic light use since I purchased it in the 1990's.

    I have a "User Manual" in English/French/Spanish on every page. I can scan that to a pdf if it is of interest to others. Please indicated where and how to upload it.

    For those asking about a replacement chain, it is 0.050 gauge, with a 3/8" pitch and 50 drive links.

Your problem is a simple one. the chain is too tight. loosen the two nuts that hold the bar in place and use a flat blade screw driber to turn the tension screw a wee bit to loosen the chain just a little. finally spray some wd-40 or other lube on the bar and chain and you will be fine.

Why does my electramac leaks oil


The chain oil feed is a gravity feed and will continue to feed when you put the saw down. Empty the chain oil resoivour when the machine is being stored. or store it in a driptray.

Oil leak mcculloch electramac em250 ?


You have a cracked tank, or busted chain oiler. Will have to take apart to view the chain oiler , and check if oil is puddling just under the oil tank. There is some epoxy sealers, or gas tank stop leak material that can possibly repair the busted or leaking oil tank.

The blade on my McCulloch Electramac EM250-14 came off. How do I put it back on? Dan Enright


I am not familier with this machine, hoever the principle is the same for most machines, start by removeing the bar nut/nuts, remove the side cover, wind the chain adjuster screw fully back it may be in the saw or in the side cover, push the guide bar fully back, now loop the chain over the sprocket and lay it into the top of the guide bar, and around the tip, the cutting edge of the chain in the top of the guide bar should be facing away from the saw ( the chain rotates clockwise as you look at it ) replace the side cover, make sure the adjuster pawl is in the hole in the guide bar, assemble the nut/nuts finger tight, now adjust the bar so as the chain is touching all the way around the guide bar, with a gloved hand pull the chain around the bar manually to make sure it is properly on the sprocket, re tention the chain if required, lift the tip of the bar and fully tighten the bar nut/nuts, the chain should not sag on the bottom of the guide bar.

Motor spins but chain doesn't move


If this is an electric saw, you may have a damaged gear within the gearbox, or the chain drive sprocket is spinning freely on the output shaft due a part breakage or similar. If this is a fueled saw, then wash out the clutch internals with spray carburetor cleaner and allow to dry out. Make sure that you can move the chain by hand and is being oiled properly. Hope this helps!

Mcculloch EM250-14 RPM Slowed suddenly


The chain must be properly sharpened to cut efficiently and the oil pump must be feeding oil to the chain/bar. Check the oiling by running the saw with the bar tip near some cardboard for a few moments--it should throw off a thin line of oil on to the cardboard. If not, remove the bar and chain and run the motor for a few moments--it should ooze oil out of a side port that exits near the drive end of the bar. If still nothing, check the oil tank filter for plugging, then the oil pump itself--it may have a plastic gear that has stripped it's teeth. Once you get oil from the side port, clean the oil passages in the drive end of the bar, and reinstall the bar and chain. Hope this helps!

Chain comes off mcculloch electramac em250 chain saw


Adjust the chain until you can pull on it and it will come away from the bar but will not hang from the bar. If that does not solve your problem then the chain or drive gear is worn out. If the oiler is not working it is for sure worn out.

Chain comes off mcculloch electramac em250 chain saw


Your chain is too loose or it is worn out. Adjust the tension on the chain. The chain should not hang away from the bar but should be loose enough that you can pull it away from the bar with not much effort. Adjust the tension until it is set correctly.

I have a McCulloch Electramac 416 electric chainsaw, now out of guarantee. Recently the chain has stopped turning, although the motor appears to function. The safety brake is not engaged. I cannot see any...


She is English? You can download a manual here:

There are 3 please ensure this is your saw.

Using this IPL as a guide it appears reasonably simple.
I'd ensure it is unplugged, the chain brake disengaged, and try to move the chain by hand (gloves are a good idea). If you can't move the chain or the clutch cover seems stuck use the "Service Locater". If you can move the chain; remove the clutch cover, loosen the bar and remove the chain. I see no reason the saw cannot be operated for short periods without the clutch cover to aid in isolating the problem. She will oil your mate won't be happy if you oil the table. GL
