How to Install Ryobi Bump Feed Trimmer Heads

Ryobi Products is a company famous for their lawn equipment made from gasoline.

One of its famous products includes a complete line of string trimmers.

If the cutting attachment attached to your trimmer has been broken or worn out, owners should remove and replace them; this will only take a few steps and a few minutes.

The bump head spring provides the tension to the bump head knob.

It is done to return the head knob to its proper position after it makes contact with the ground to feed more line.

This spring can get weak through time.

When this happens, the bump head trimmer may feed lines inconsistently, and the bump head spring should be changed immediately and probably a new bump feed head.

Here are the steps that you need to take to install a Ryobi Bump Feed Header:

1. Invert the Trimmer

With the Ryobi Weed Trimmer upside down, you can now see the bottom of the lawn tool.

This was done to place the cutting head at the top and in front of you so you can examine the bottom part of the Ryobi Weed Trimmer, where you will install the feed header.

2. Loosen the Bump Head

Loosen the bump head or bump knot by unscrewing it in a counter-clockwise motion to avoid having a loose thread on the screw ridges.

If it shows more resistance, use pliers for more grip and leverage, as well as avoid any unnecessary injuries that may be due to forced pulling.

You should now be able to remove the bump head or bump knot and keep it somewhere safe.

3. Remove Inner Spring Reel

After temporarily removing the bump head, remove the inner string reel from the innermost part of the cutting head and keep it in a safe place.

Avoid breaking or misplacing this inner reel spring to avoid any mishaps.

At this point, you can now see the lower part of the engine shaft.

4. Grasp the Shaft Housing

After you have seen the lower section of the engine shaft, using your non-dominant hand, grasp the shaft housing firmly.

Then using your dominant hand, shake off the cutting hand while gently pulling it out upwards.

Continue making this motion until the cutting head slips off the large hex nut it is on.

5. Replace Cutting Head

Attach the new cutting head to the large hex nut.

Gently press, then return the shaft housing in place.

Make sure that the fitting is firm, and you might have to give a little extra effort in order to tighten the attachments.

That is to avoid any unexpected movements of the reattached shaft housing.

6. Add Spring Reel on the Housing Shaft

As mentioned, the inner spring reel should be attached in the innermost part of the housing shaft.

You will notice that the lower part of the engine shaft will now be hard to see if you have attached the spring reel properly in place.

Make sure that the spring reel is correctly placed on the housing shaft since it is one of the most important innermost parts of the housing shafts.

7. Tighten the Bump Head Back

You now have to return the bump head in place.

Use a clockwise motion to tighten the bump head, while being careful with the other parts.

You may use other tools, like pliers, to put it in place more easily.

That will also avoid any unnecessary muscle strains if you force yourself to do it by hand.

8. Run a Test

To make sure that the installation was successful and the weed trimmer is working properly after you have installed the head, try a little test run before using it on your lawn.

Depending on your ability to handle tools, the above steps can be done in just ten minutes, not wasting any time to start on your scheduled lawn trimming.
