Step 1: Identifying The Attachment Type

One of the first steps you need to do to identify the issue is assessing the weed eater connection type. If you are using an older weed eater, the attachments can be built-in.

In this case, it is unable to come off and you have no choice but to replace the entire equipment. When you possess a recent machine, there are two head types, including knob head and screw head.

Step 2: Turn Off The Power

Either you use the knob head or screw head, you have to turn off the power first. Usually, the weed eater that comes with a gas or electric-based design features a knob head.

After powering off, you can push down on the head, and it will pop off.

In case you have a machine with a screw head, you rotate the item in a counterclockwise direction and it comes off.

Step 3: Clean The Device

If you have used the equipment for a long time, it is advisable to take off the grim and clean it. Dirt, mud built-ups, leaves can make the head jammed.

One of the effective ways to do the job is to use a durable towel. It would be best if you first dipped the towel in water and then wipe down the grim. Repeat doing it until the trimmer head is free from dirt.

Step 4: Removing Spool

Many devices have a spool of line that goes around the head. Thus, to remove it, start taking off the spool in the first place.

You should push the line in and then twist it. The spool now is becoming loose and you just need to slowly pull it out.

However, different weed eaters from various brand names on the market have their own shapes.

If the above step does not work for you, you may need to read the user’s manual or contact the manufacturers.

It is because if you do the task improperly, you can permanently damage the device, and the spool will be clogged.

Step 5: When There Is No Spool, Seeking The Remaining Bolts And Nuts

Some standard eaters nowadays do not go with a spool, so you need to identify the remaining bolts and nuts.

These items help attach the head of the equipment to the body. If you want to remove them, you should unscrew them by using wreches.

However, you have to spent time locating the nuts and bolts because they are pretty small.
