6 Steps To Re-stringing Electric Weed Eater Properly

Re-stringing an electric weed eater can seem like a difficult task. You may think that each model of an electric weed eater has a different method of eating weeds and being re-strung but this is not the case.

For the most part all electric weed eaters have the same body type and the same nylon-like string used to do the trimming.   In the vast majority of cases these directions will help you restring your trimmer with the least amount of trouble.

Electric string trimmers are  one of the more popular types of weed whackers that are use.  There are two other types – the gas powered weed eaters or the battery powered weed eaters. They all do the same thing, they cut the weeds but they all do it in a different way.   They all have the same mechanisms to restring their heads as well.

Kinds of Electric String Trimmers

Some consumers do not know that there is more than one kind of electric string trimmer; the more popular version and well-known type of electric weed eater is the one that has a cord and gets plugged into an outlet. There is also a cordless version of the weed eater available on the market. This is usually referred to as a battery-powered weed eater.

Either kind of electric whacker does have the same problem of needing to have the string replaced, when it breaks, when it becomes tangled and or when it dulls out with consistent use. The string needs to stay sharp and needs to stay pulled out a certain length to guarantee a well-groomed yard with each and every use.

Tip: A good rule of thumb is that you need to pull out enough string from the spool head to cover the cutting distance divided by two, minus an inch. For example, if you have a 15″ cutting area string trimmer, pull out 7″ worth of line.

Know Your Spool Type

The follow instructions are for a single-sided lawn weed eater spool.  You have this type if your spool only hangs out one string at a time.  There are also dual-sided models – these use two strings at the same time.  Usually the spools have two channels instead of one around the outside of the spool “circle”.

If this is your case, you can follow directions below.  When restringing, you’ll need to do both lines at the same time.  It will make your life easier – otherwise it’s difficult to keep the newly-strung line on the spool while working on the second part.  Here’s a decent video showing you the process in more detail.

Steps to Re-Stringing an Electric Weed Eater

Step One

Begin by having the trimmer unplugged or if it is the cordless one, remove the battery pack. This is done so the piece of equipment does not become accidentally engaged while you are working on it.  Safety first!

Step Two

Turn the trimmer upside-down so you have better access to the spool of string. Remove the spool of string – to do this press in the two tabs on the spool that are holding it into place.  Sometimes you’ll need to remove a spool cover to get to the tabs.

Step Three

Remove the spool by firmly pressing on the ‘tap’ button.  You usually can find this on the underside of the spool – but it might be located slightly differently on your particular model. Press this button in and slide the empty off of the spindle in one swift motion.  While you are looking at the bottom of the spool, look for an arrow.  This will indicate which direction you need to reload the string.

Step Four

Once you have removed the old spool of string you will then need to replace it with a new spool trimmer line. You can either use a spool of string that is pre-strung or you can re-string the existing spool.  I’m going to be honest – I think restringing your own line is a pain, takes up a decent amount of time, and doesn’t save you that much money.  I’d much rather just buy a new pack of line and be done.

Some people enjoy restringing – if you think that might be you read on.

To re-string the old spool, get some replacement string.  Measure out roughly 9 feet worth of line, and cut it off.  Place one end of the string into the anchor hole.  Begin wrapping the string around the spool TIGHTLY. Don’t let slack develop in the spool – it will help avoid problems down the line.

Only use string that is the same thickness of the string that was originally used on the piece of equipment and keep in mind that the string should be about the same length as the old trimmer line as well.

Step Five

Take the end of the eater that is free and line the line through the opening of the exit hole which is found on the hub of the housing spool area. The notch in the spool should be perfectly aligned with the exit hole to ensure that it will go where it needs to go and nowhere else.

Step Six

Finally you need to press the spool of string directly into place.  When it’s locked inplace, you will hear a slight click.  If your version of the electric weed eater has a cover that goes over the spool of line you need to replace the cover before use.

Once the spool is inserted back into place and everything is aligned and the cover is on, you are ready to tackle your yard.  Good luck!
