Oil comes out the cover and doesn t oil bar and chain

take off the side cover over the chain clutch/drive, don't forget to loosen the chain tension before removing, clean thoroughly, clean oil ports on saw and on the chain bar (little holes)clean the chain bar. Start the saw with the chain and bar removed and you should see oil coming from the port on the engine. Reassemble

The marks on the drive links are because the chain has come off, not the reason why it has come off, if this is the tooless chain adjuster i would replace the side cover with the non tooless cover you can then tighten the nut up with a 13mm spanner, you also need to check the machine is oiling adiquatley, aim the tip of the bar at a tree stump and check you have a good spray of oil coming from the bar.

Remove the bar and chain, then clean the side of the engine case where the bar fits to. Start the engine--oil should ooze out of a small port in the engine case. If ok, clean the bar and cover, then clean the two small oil channels in the drive end of the bar which allow oil to flow out into the chain groove on each side (only one is active depending on which side of the bar is 'down'). If no oil came out of the engine port, then you need to investigate the oil pump (behind the clutch), oil lines, and oil filter in the tank. The oil pump, in particular, has plastic gears that can become damaged. When oil appears at the port, assemble the bar and chain. Adjust the chain (cover fastemers finger tight) so that the chain just pulls up to the lower bar edge, but not so tight that the chain can't be pulled by hand. Make sure the teeth cut toward you on the bottom run and are properly sharpened. Tighten the cover fasteners firmly and recheck tension. If ok, run the saw at speed for several moments with the tip near some cardboard--it should throw off a thin line of oil. Hope this helps!

Remove the bar and chain and wash out the clutch internals with spray carburetor cleaner. Clean the side of the engine case, start the engine and watch for oil oozing out of the side port. Clean the bar drive-end small oil passages that go out to the chain groove on each side and clean the entire chain groove. If oil came out of the engine side port ok, then re-assemble the bar and chain, but leave the cover fasteners only finger tight. Tighten the chain so that the chain comes up to the bar, but not so tight that the chain can't be pulled by hand. Tighten the cover fasteners and recheck the chain tension. Make sure the chain teeth cut toward you on the bottom run and that the chain is properly sharpened. Hope this helps!

Does the brake seem to 'snap-over' like it should? Pull it back to release position, and remove the drive cover. Check the entire brake for debris accumulation or bent/damaged brake band. Check the chain to see if it is being oiled. Remove the bar/chain and clean the entire assembly, particularly the small oil passages in the drive end of the bar. Start the engine and watch for oil oozing out of the small side port where the bar fits. If ok, reassemble the bar/chain. If no oil comes out, investigate the oil pump, lines, and filter/valve in the oil tank. Mount the side cover, but leave the fasteners finger tight. (The chain teeth cut toward you on the bottom run) Tighten the chain until the lower run comes up to the bar, but can still be turned by hand. Tighten the fasteners and recheck the tension. Trip the chain brake and make sure it locks the chain, then release it and make sure it turns freely. Check the chain oiling by running the bar tip at speed near some cardboard--it should leave a thin line of oil on the board. Hope this helps!

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!

Remove the bar and chain from the engine. Clean the entire area where the bar fits to the case. Start the engine--oil should ooze out of the side port only. If ok, clean the bar drive-end small oil-channels that bring oil to the chain groove on each side of the bar. Also, clean the entire chain groove. Refit the bar, chain, and cover leaving the fasteners finger tight. Turn the chain adjuster CW until the chain comes up to the bar, but not so tight that the chain can't be turned by hand. Tighten the cover fasteners and recheck the chain tension. Start the engine and run the bar tip at speed near some cardboard--it should throw off a thin line of oil after several moments. Hope this helps!

remove side cover,bar & chain.ther is an ob long channel above the bar mounting studs that lines up w/the small holes near the edge of the bar,thats where the oil comes out.clean everything.sawdust gets packed in the holes & stops the oil flow.

The bar and chain are running without oil. Take the side cover off where the chain is driven from and remove the bar and chain. Use compressed air to blow all debris from the area. Start the engine and watch for oil coming out of a small port near the clutch assembly. If oil passes (good!), then clean ( at the drive end of the bar) the two smaller holes and their passages into the track which the chain runs in. They are likely to be filled with sawdust and other debris. Clean the entire chain track around the whole bar. Use engine oil in the two small holes at the bar tip to lubricate the sprocket bearing. Back off the chain adjuster screw somewhat and reassemble everything--put the bar on first and then work the chain on, then the side cover--work the bar fore and aft to allow the small tang of the adjuster to drop into it's hole at the bar rear. Make sure that the cutting side of the teeth are pointing toward the engine on the bar bottom. With the cover on and mounting nuts slightly loose, adjust the chain tightness so that the chain doesn't droop away from the bar bottom, but still allows the chain to be moved by hand--remember to lightly oil the chain first with engine oil. Tighten the bar mounting nut(s) and recheck the chain for droop. Make sure that you have bar oil in the tank, then start the engine and hold the bar tip near a piece of paper or cardboard. After running for a little while, the tip should throw off a very thin line of oil. Next, if you have a vise, put the bar center into the vise so that the chain is free to turn. At this point you need to file each tooth to sharpness at 30 degrees from perpendicular to the bar and 10 degrees below chain horizontal. Make sure you use the correct size file for your chain. Work your way through one side, then work the other side--be consistent with cutting angles during filing as uneven filing will result in the chain trying to cut at unintended angles.
If no oil came out of the engine when running the bar-off test, make sure there is ample oil in the tank, then you have either a plugged inlet filter in the tank, tubing kink/breakage, or a defective oil pump. You must be sure that oil is being pumped from the chain drive area before putting things together. Hope this helps!

May be oil port on saw clogged. Remove side cover, remove bar and chain. Remove giude plate if equipped. Check to see if small oil hole on saw is open and clean. You can start the saw with side cover removed to see if oil is coming from oil hole or not. If it is coming from oil hole when running the problem is most likely dirty bar .If bar is dirty check to see that groove is clean and the oil hole along the edge of bar is clean also. The hole is at same end of bar that attaches to saw.
