8" line feed no bump required EXPERT gardener weed whacked replacement spool

If the line simply came loose from spool, you can usually re- wind line back onto spool tightly in a clockwise direction then replace spool on weedeater and guide end of line out the little hole and replace cover/cap.

In my limited experience all but the very cheapest strimmers have a bump feed line head fitted. These aren't foolproof but I find them less bother and less difficult than the manual feed type.

The main consideration seems to be reassembly after winding the new line onto the spool. Most spools have helpful arrows for the winding direction but sometimes the spool will fit on the spindle either way and the position of the spring isn't always obvious. I have one and the spool is marked this side top. The obvious thing is not the right thing as they assume the machine is upside-down.

Once assembled a bump-feed line head should move against the spring with a firm hand pressure freeing the spool so the direction of travel feeds out more line. The correct line diameter is important. If the head will not move up to free the spool it is assembled wrongly or an accumulation of grass, weeds and nettles has fouled the operation and it should be cleaned and maybe lubricated a little.

Hi Rick:
"Bump feed" spools are designed to be able to be re-loaded.

There is usually a screw-in retainer (often with a reverse thread so it turns clockwise to remove) that allows the spool to be removed. Then it is a matter of winding on enough line to go and attack the weeds again.

I have a Ryobi Model RY28040 straight shaft line trimmer. In my case I replaced the complete String Head Assembly that includes the String Head Housing, Spring, and Spool and the string still did not advance. I then discovered that the bolt in the Spool Retainer cap (the red cap that attaches the spool to the shaft) was fused and not moving. The bolt needs to be loose inside the cap in order to allow the spool to move in and out by the spring. I loosened the bolt and fastened the spool back onto the shaft. Fired it up and bumped it a few times and the line began to advance. Turns out I probably only needed to replace the Spool Retainer rather than the String Head Assembly.

Here is the info from the manual, the replacement line is put in near the center of the spool on the top of it, you simply feed it in. I have included a link to the manual so you can see the pictures. Look at page 10 for these instructions.

LINE REPLACEMENT Pre--wound spools offer the most convenient method for replacing line and ensuring optimum performance. S Replacement spools are color--coded to ensure use of the correct spool with your unit. Be sure to use the same color spool as the existing spool. NOTE: Always clear dirt and debris from cutting head components when performing any type of maintenance. S Hold spool and unscrew cap by turning in the direction shown on top of the cap. S Remove line guide ring and spool. NOTE:When removing and/or installing spool, ensure dust cup remains installed over shaft. Use a pre--wound spool or refill spool with line. If using a pre--wound spool, remove tape strip from line and spool. REFILLING THE SPOOL WITH LINE WARNING: Use only 0.080" (2 mm) diameter round line. Other sizes and shapes of line will not advance properly and will result in improper cutting head function or can cause serious injury. Do not use other materials such as wire, string, rope, etc. Wire can break off during cutting and become a dangerous missile that can cause serious injury. 1. Cut a length of 25 feet of 0.080" (2 mm) diameter round WEED EATER brand line. Feed line in direction shown on spool. Spool 2. Insert one end of line into center cavity of empty spool. Ensure line will feed into spool in the direction shown on the spool (counterclockwise). 3. Continue feeding line into spool, leaving 4 -- 6 inches (10 -- 15 cm) unwound from center of spool

the notice on the trimmer says it has an AFS Automatic Feed Spool, "NO BUMPING REQUIRED". I see that underneath the spool, there's a small plastic centrifugal weightwith a peg on it. . It kinda looks like it might advance the line each time the electric motor starts and stops. If there are loose clippings in there, or if the weight is stuck, it probably would cause the problem.

Just replace the LEVER, Item #29, Part #598435-00, for about $3.00 (B&D, Dewalt). Just pull old level straight out (pliers) and push replacement in. Level end expands to hold it in place. No other parts. Forget cleaning and replacement the spool, graphite or oiling... just replace the lever.

be sure you wound the line in the correct direction on the spool? (see arrow on the spool for winding direction)
and you have the correct line diameter for that spool?
Be sure the bump knob is free and it moves up and down without issue by hand.
