The 450E is a tooless system, make sure the brake is off by pulling the handgurd fully back to the top handle, flip up the lever on the big grey fixing nut, undo counter clockwise, wind the grey knurled adjuster wheel facing out of the cover fully back, remove the chainbrake side cover, push the guide bar fully back toward the sprocket, you now have enough rome to replace the chain onto the guide bar rails, now re fit the side cover, make sure the adjuster pawl in the cove aligns with the adjuster hole in the bar, re fit the big fixing nut finger tight, wind the adjuster wheel down to re tention the chain, when the chain is snug all the way around the bar tighten the nut fully.

Chain came off chainsaw while cutting limbs and wouldn't fit back into the groove on the bar


Had this happen to me. The portion of the chain that goes in the groove on your bar now has been burred. The burs make the chain too wide for the bar.. Problem can be easily fixed with a flat file or bench grinder. Simply but carefully file or grind the burs off so the chain will fit back into the groove on the bar.

Chainsaw's chain keeps on getting out of its track. Please help with ways to fix it.


With the saw not running (and wearing a glove) try pulling the on the chain towards the end of the bar. If it feels rough then either the chain or the bar may be damaged. Try taking the chain off of the bar and using a bent piece of wire or large paper clip, clean the track of the bar of any wood deposits. Also check the sprocket on the end of the bar to make sure it tuns freely. If all these areas are clear then try another chain if available. If the problem still exists then the bar may be worn to one side which sometimes can be filed back in shape by a shop where chains are sharpened.

Remove the side cover nuts and the cover, wind the bar adjuster screw fully back, it may be in the cover, or on the front of the saw, push the guide bar fully back toward the sprocket, loop the chain ocer the sprocket and lay it around the the guide bar, make sure the cutters on the top of the bar rail are facing away from the saw, this will make sure it is the correct way round make sure the bar adjuster pawl is engaged into the hole in the bar, if the adjuster pawl is in the cover, replace the cover making sure the pawl engages into the hole in the bar, refit the cover nur finger tight, adjust the adjuster screw so as the chain fits snug fully around the bar, loft the nose of the bar and fully tighten the cover nut, with a gloved hand pull the chain manualy around the bar to make sure it is fitting in the rails and the sprocket correctly.

How to change a chain


First of all, make sure the saw is off. Also, before removing bolts, make sure the chain brake is not engaged (the chain should move freely).
Remove the guide bar side panel. Using a scwrench or wrench, unscrew the nuts and remove the plate to access the chain.

The side plate on most chainsaws will be held on by two nuts. Loosen the blade adjustment screw (a pin that is usually driven by a screw and pushes the blade out from the chainsaw to keep the chain tension tight).

The old chain is ready to be removed now that the sprocket plate is off of the saw. Pull the nose of the chainsaw's bar away from the chainsaw to release it from the tensioner.

Remove the old chainsaw chain.

The chain will easily remove from the guide bar with all that slack in it. Note the orientation of the cutting edges of the chain so you put the new one on the same way.

Pull the drive links out of the guide bar and slip the other end of the chain around the clutch drum.

Steps to Install a New Chainsaw Chain
Thread the new chain onto the saw.

Carefully thread your new or recently sharpened chainsaw chain around the chainsaw's clutch drum, making sure that the drive links engage in the sprocket.



Thread the rest of the drive links into the guide bar and around its nose, making sure all links are in the guide bar slot.
Align the guide bar.

With the chain properly threaded along the clutch drum and guide bar, put some tension into it by pulling on the nose of the guide bar away from the chainsaw.



While pulling the guide bar, make sure to seat it onto the saw's adjustment pin.

Replace the side plate.

The side plate is ready to go back on as long as the guide bar is properly positioned beneath.

Replace the plate and the nuts that hold it into position, but do not tighten the nuts down all the way yet. The guide bar must be allowed to move a little while the chain is tightened to the correct tension.
Tighten the chain to the correct tension. Use the tensioning screw to the side of the guide bar to adjust the tension on the chainsaw chain.



Finish tightening the side plate nuts.

The chainsaw chain replacement is now complete.


And here is a great overall reference guide to keeping a chainsaw sharp and running. Sharpening a chainsaw chain is a great way to extend the life and is less expensive and easier than replacing a chain. There are small grinding tools (like a dremel) that can be run off a small 12v battery or your vehicle battery that allow for quick 'tune-ups' on your chain if you are out cutting and need to sharpen your chain.

I can not keep the chain on. I replaced the bar and chain. It work fine for about 2 hours. Then the chain came off and would not stay on.


If there is no damage to the chain or bar (shouldn't be any if you replaced them), then there seems to be some other possibilities:
1) The sprocket, that transfers power from the motor or engine to the chain, could be damaged so that it does not keep the chain in position
2) The bar is no longer perpendicular to the sprocket and housing for the motor/engine. If the bar is at an angle then the spinning forces would tend to slide the chain out of the slot in the bar.
3) The tension on the bar is not being maintained so that it slips out of the bar slot. You need to monitor this tension as you are working because the forces on the chain an bar tend to push the bar back into the housing, loosening the chain and making it susceptible to slippage.

How do I tighten the chain on my remington 16in electric chainsaw?


There are two nuts that hold the bar in place. They should be 7/16. You need to loosen these nuts and then you can adjust where the bar sits with a flat bladed screwdriver. It works on the right-y tight-y principle. The adjustment screw should be at the front of the chainsaw right next to the bar. The chain should be able to be lifted from the groove in the bar and snap back into place. Then re tighten the 7/16 nuts and you should be back in business.

The chain has come off of my 14'' poulan gas chainsaw and I can't get it back on?


Release chain tension. Loosen nut on bar, re-install chain, check for chain not binding when moved by hand, but snug on bar, tighten and you should be back in business.
