A bump feed trimmer is a lawn care tool that uses a trimmer line on a spool. The trimmer line is fed through the head of the trimmer and cuts the grass and weeds as the trimmer is pushed along. The bump feed trimmer is a handheld tool that is powered by either an electric motor or a gas engine.

The bump feed trimmer line is advanced by repeatedly striking the ground with the head of the trimmer. As the head of the trimmer strikes the ground, the trimmer line is pulled from the spool and advances through the head. The length of the bump feed trimmer line can be adjusted by turning a knob on the side of the trimmer head.

To use a bump feed trimmer, start by checking that the area to be trimmed is clear of debris. Be sure to wear protective eyewear and gloves when operating a bump feed trimmer. Hold the trimmer with both hands, keeping your fingers away from moving parts.

Depress the trigger to start the motor or engine, then guide the head of the trimmer along the edge of lawn or garden bed. Be careful not to over-extend your arms while trimming. Take breaks as needed to rest your arms and shoulders.

When finished, turn off the motor or engine and release the trigger. Disconnect any power source before performing maintenance on your bump feed trimer, such as replacing worn-out lines or cleaning out debris from inside

What is a Bump Feed Trimmer?

A bump feed trimmer is a type of string trimmer that uses a spool of line that is fed through the head of the trimmer by a spring. As the trimmer is used, the line wears down and eventually needs to be replaced. To do this, the user simply bumps the trimmer head on the ground, which causes a new length of line to be fed through.

Bump feed trimmers are available in both gas and electric models, and can be used for a variety of different tasks such as trimming grass, weeds, and other foliage around the home. While they are relatively easy to use, there are a few things to keep in mind in order to get the best results.

Here are some tips on how to use a bump feed trimmer:

-Start by ensuring that the trimmer head is properly positioned on the shaft of the trimmer. It should be securely attached so that it does not spin or come loose while in use.
-Next, feed a length of line through the head of the trimmer. Make sure that there is enough line to reach all areas that you need to trim.
-Start the trimmer and hold it at waist level with the cutting head pointing down. Slowly move the trimming head around in small circles to avoid damaging any nearby plants or objects.
-As you work, keep an eye on the amount of line that is being used. When it starts to get low, simply bump the head of the trimmer on the ground to feed more line through.
-When you are finished trimming, turn off the trimmer and release any remaining line from the cutting head. Be sure to also disconnect any power source before storing your bump feed trimmer away.

How to Use a Bump Feed Trimmer

Bump feed trimmers are a great choice for those who need a durable and long lasting trimmer. This type of trimmer is designed to be used on a variety of different surfaces, including concrete, asphalt, brick, and more.

Step One: Fill the trimmer head with line

To use a bump feed trimmer, first you’ll need to fill the trimmer head with line. Most trimmer heads hold between 10 and 20 feet of line, so you may need to add more line as you go. To do this, simply twist the head counter-clockwise to loosen it, then pull out the old line and dispose of it. Next, cut a length of new line that’s about 2 feet longer than the old line, then thread it through the trimmer head. To secure the new line, twist the head clockwise until it’s tight.

Step Two: Attach the trimmer head to the trimmer

To attach the trimmer head to the trimmer, locate the head lock knob on the back of the trimmer. Then, find the powerhead housing on the trimmer. There will be a hole in this powerhead housing that is lined up with a hole on the back of the trimmer head. Take the trimmer head and line up these two holes. Once they are lined up, insert the knob into the hole on the powerhead housing. To secure it, twist the knob clockwise until it is tightened.

Step Three: Turn on the trimmer

Now that the trimmer is fueled and the cutting head is in place, it’s time to start trimming. To do this, simply turn on the trimmer by pressing the power button. You may need to hold the button down for a few seconds before the trimmer turns on.

Step Four: Guide the trimmer head along the edge you want to trim

As you guide the trimmer head along the edge of your lawn, keep the following tips in mind:
-The trimmer line will extend automatically as you need it.
-Apply gentle pressure to the trimmer head as you move it along the edge of your lawn.
-Keep the trimmer head close to the ground for best results.
