How do I put chain back on the Wen 14'' chain saw
Remove the chain drive side plate and remove the bar. Clean the drive area and inspect the drive sprocket for excessive wear. Run the motor for a short time to make sure that oil is being pumped out to the bar--is should just ooze out. Clean the bar chain groove and clean the oil holes at the drive end of the bar--especially the two small holes that go from the large oil holes out to the chain groove. Back off the chain adjustment screw several turns, then fit the chain over the sprocket (teeth cut toward you on the bottom) and then insert the bar into the chain and push the bar out till the chain is fairly tight. Apply the side cover and make sure the adjustment tang drops into the large hole at the rear of the bar. Install the mounting nut(s) to hold the plate and bar together. When run-up finger tight, turn the adjustment screw CW until the chain becomes tight enough that it doesn't droop from the bar, yet can be be turned by hand. Tighten the side cover nut(s) and recheck tension. If ok, run the saw for a few moments with the bar tip near some cardboard--it should throw off a thin line of oil. Keep the chain properly sharpened to reduce the chance of this occurring again. Hope this helps!
