Brand new fs38 trimmer and I can't get the bumpfeed to work. have to pull string with pliers

SOURCE: ryobi weed trimmer

I have one of this trimmers. It is simple to replace the line. 
-First line up the arrows on the bottom of the spindle. 
-Then feed the line back in one of the holes in the side of the spindle (this is the same hole that the cutting string comes out of). 
-You will see the line come out of the bottom of the spindle. 
-Take that line a place it in the hole on the bottom of the spindle. 
-Leave about 9 feet of string hanging out of the weed eater (do the same with the other side). 
-Then turn the inside wheel (I can't remember if it is clock wise or counter clock-wise but it will only turn one way) most of the string is rolled into the spindle. 
-Cut the string of about 5 inches out of the weed eater. You're ready to cut!

SOURCE: TROY BILT TRIMMER MODEL TB70SS. HOW DO I REPLACE

Is the pull rope in the front or rear of engine.Thinking that the string is in the front,you must throttle housing and shaft from engine. remove starter housing. There sould be a screw holding the string and spring in place.

there are two ways to install the string..the cool way is without pulling the inner reel off the trimmer..just leave it in place..cut (2) approx.two arms length (thats spreading your arms out like airplane wings) of .095 string..now, align the arrow of the inner reel (it turns counter clock-wise..the arrow points outward) with the arrow on the outer spool (pointing inward)..holding the spool and reel together so the inner reel doesnt move, push one of the cut strings through the eyehole in the side of the outer spool, and it should come up to the right, through a slot next to a small round hole the diameter of the string..if it doesnt, it just missed the exit (as i call it)..pull out and try again..let about an inch come thru..now take that end of the string and push the line into the little round hole until it stops, which should be about a little more than 1/8 of an inch..hold it in while pulling the excess line outside the spool to keep it in place..now do the same with the other string for the other side..once you have both lines in place, turn the inner reel counter clock-wise to draw in both lines through the eyeholes of the outer spool..you may or may not get all of the line to wind in..not a problem..you will still have enough to do what you need to do..just cut off the rest..one problem you may or may not have that i do most of the tyme is that it gets hard to turn the inner reel..one solution is to bump the top of the 'bump knob' with your fist, then pull both strings at the same tyme, then continue to turn..this method is quicker and easier than the second way of having the inner reel out and trying to wind both lines at the same tyme and trying to place the reel back in the spool..hope this works for you...

SOURCE: B & D auto feed string trimmer won't advance string

Is the string spool seated on the rachet correctly? If so and all is well, it is worth noting that these trimmers auto feed fuunction is problematic at best, requiring manually unwinding some line every few minutes as the unit gets older.
