How to put the chain back on a 16" Poulan electric chain saw


its probably like the gas model. so you remove the 2 nuts holding on the side cover of the blade side, remove the cover and the blade and chain. To fit back, slacken the adjuster screw a little bit, or if fitting a new chain then a fair amount, as you have to be careful that the pin on the adjuster fits into the proper hole on the saw bar, as you fit back on the bar, of which you have already cleaned out the grooves. supporting the bar in the slackest position, fit on the chain, making sure that the cutting edge at the bottom is coming towards the motor. Then slide the bar and chain away from the motor to take up the slack, then fit back the metal guide in the original position, fit cover with the adjuster pin in its hole on the bar, and replace the 2 nuts almost tight but slack enough to use the adjuster to set the chain to cutting position..slightly sagging on the sprocket nose type, or snug on the solid nose type..then tighten the cover 2 nuts firmly but not excessively as that will damage the machine..NB the bar & chain depends on the adjuster, not on the nuts tightness to maintain tension

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

Make sure the chainbrake ( if if fitted ) is off by pulling the hand guard fully back to the top handle, remove the securing nuts and remove the side cover, wind the chain adjuster back if it is in the crankcase, pull the bar fully back, now loop the loose chain off the tip of the bar and over the sprocket, re fit the new chain over the sprocket, and lay it around the guide bar, place the bar adjuster hole onto the adjuster pawl ( if it is in the crankcase ) refit the side cover, if the adjuster pawl is in the side cover make sure it fits into the hole in the bar, put the securing nuts back on finger tight, adjust the chain so as it fits snuggley around the bar, with a gloved hand pull the chain around the bar to make sure it is seated correctly, re adjust if required, lift the bar nose up and fully tighten the securing nuts, after the first ten minutes of use re check the chain tention as there will be an initial stretch.

Chain has come off how do i put it back on?


The chain drive links may well be damaged now, it may need a new chain, however,if it has a chainbrake make sure this is off by pulling the hand guard fully back to the top handle,wind the chain adjuster fully back, remove the the side cover nut and remove the side cover, push the guide bar fully back, loop the chain over the drive sprocket, and lay it into the guide bar rails ( the cutters on the top bar rail should face away from the saw ), refit the side cover, if the adjuster pawl is in the cover make sure it aligns with the hole in the guide bar, fit the bar nut finger tight, adjust the chain so as it fit snuggly all round the bar, with a gloved hand pull the chain around the bar to ensure it it is sitting in the sprocket and rails properly, re adjust the chain if it has come lose, now fully re tighten the bar nut. If you fit a new chain there will be an amount of initial stretch, so re tention after a few cuts.

How do i put a chain back on a chainsaw?


Locate the bolts on the bar, down close to the engine. Loosen them. locate the chain tensioning adjustment, again, close to the engine, but on the other side. Loosen it also. Place your chain on the bar and on the sprocket. Tighten the bolts enough to take the slack out of the bar, but not so much that you cannot use the adjustment tensioning screw. Tighten up on the tension adjustment until the tension on the chain is right, and then tighten the bolts.

How do I refit chain


Start by removing the side cover held with one or two nuts ( make sure the chainbrake if fitted is de activated by pulling the hand guard fully back toward the rear of the saw until there is an audible click ) if the chain has de railed you need to check for damage to the drive links, file away any burs, or fit a new chain, screw the chain adjuster fully back, assemble the guide bar onto the bar bolts and push fully back toward the rear of the saw, loop the chain over the sprocket and into the guide bar rails with the cutter teeth on top of the bar facing away from the saw if the bar adjuster pawl is in the crankcase make sure it fits into the hole in the guide bar, assemble the side cover, if the adjuster pawl is in the cover make sure this lines up with the hole in the guide bar ( adjust the pawl screw if required ), assemble the bars nuts finger tight, now adjust the pawl screw so as the chain sits snuggley around the guide bar, pull the chain around the bar with a gloved hand to make sure it is sitting into the bar and sprocket correctly, lift the nose of the guide bar and tighten the bar nuts.

Need to replace chain on farm boss with 20 inch bar how do i get to sprocket to get old chain off


Release the chain brake. Remove the nuts/bolts that hold the right hand cover over the drive end of the bar. With the cover off, the bar will slide back toward the engine and allow the chain to be removed. Note the direction of the cutting teeth! Clean the side of the engine where the bar fits to, and the small oil passages in the bar drive end that run from the large holes out to the chain groove on each edge. Also clean the entire chain groove. Fit the new chain to the sprocket, then insert the bar and work the chain onto it. Pull out on the bar until the chain fits fairly tight, then fit the cleaned cover over the drive. You may have to change the position of the chain adjustment screw a few turns to allow the adjustment 'tang' to drop into one of the large holes in the bar. Make sure the cover is fully seated, then run the fasteners down finger tight. Turn the chain adjuster screw CW until the chain pulls up to the bottom edge of the bar, but not so tight that you can't turn the chain by hand. Tighten the fasteners fully and recheck chain tension. Start the engine and run the tip of the bar near some cardboard at speed for a moment or two--proper oiling is indicated by a thin line of oil thrown onto the cardboard. Be sure to keep the chain teeth sharp and properly adjust chain tension--don't allow it to droop when cutting. Hope this helps!

Chain oil flowing out afterr replacing chain adjustment screw and bolt


Remove the bar and chain completely. Clean the entire case side where the bar fits as well as the bar drive end oil passages--especially the small channels the send oil out to the chain groove on each side. Back off on the chain adjustment by several turns, then fit the cleaned cover onto the saw after installing the bar and chain. Make sure the adjustment 'tang' fits into one of the large holes in the bar end. Fasten the cover screws/nuts down finger tight, then adjust the bar out until the chain pulls up to the lower run of the bar, but not so tight that you can't move the chain by hand. Tighten the cover fasteners firmly, then recheck chain tension. If ok, do a test cut on a log. Good luck!

Oil is not coating the chain?


Remove the bar and chain after releasing the chain brake. Clean the cover and the area where the bar fits to the engine. Start the engine and watch for oil oozing out of the side port where the bar fits. If ok, clean the bar end oil passages including the two small channels that go from the large holes out to the chain groove on each side. Clean the entire groove and check the tip sprocket if equipped. If no oil came out of the port, then you need to inspect the oil pump, lines, and tank filter for plugging or damage. When oil comes out as specified, insert the bar, push back, and fit the chain over the sprocket then work it over the bar. Make sure the teeth cut toward you on the bottom run. Pull the bar out to tighten the chain, then back off the chain adjustment screw several turns. Fit the cover, making sure the adjustment tang fits into one of the large holes in the bar, the run the fasteners down finger tight. Adjust the screw till the chain pulls up to the bar, but allows the chain to be moved by hand. Tighten the mountings and recheck the tension. Run the saw tip near a piece of cardboard at speed for a few moments--it should throw off a thin line of oil onto the cardboard. Make sure the chain is properly sharpened. Hope this helps!

How to install chain for the first time


Fit the chain over the clutch/sprocket first, then fit the bar into it, then draw it out so that the chain follows the bar groove.The chain teeth must be cutting toward the engine on the bottom side of the bar. When mounting the side plate over the bar, make sure the adjusting screw prong is fitting into the associated hole at the rear of the bar. Set the chain adjustment so that the chain does not droop from the bar, yet turns freely. Run engine to check oiling of the chain.
