Safety Precautions for Bumping the Head
Before attempting to bump the head on your Greenworks 21362 trimmer, it is crucial to prioritize safety. A few essential precautions include:
1. Wear Appropriate Personal Protective Equipment (PPE)
To minimize the risk of injury, it is paramount to don the following protective gear prior to commencing work:
- Safety glasses: Shield your eyes from flying debris or trimmer line fragments.
- Earplugs or headphones: Prevent excessive noise levels from damaging your hearing.
- Gloves: Protect your hands from potential cuts, scrapes, or vibrations.
- Long pants and sleeves: Cover your skin to avoid contact with vegetation or sharp objects.
- Footwear with non-slip soles: Ensure stability and prevent falls while operating the trimmer.
Additionally, always inspect the trimmer and its line before each use to detect any damage or wear-and-tear. Report any issues to your supervisor or a qualified technician immediately.
Identifying the Bump Head Feature
The Greenworks 21362 string trimmer features a bump head, which allows you to easily advance the trimmer line by simply tapping the head on the ground while the trimmer is running. This feature eliminates the need to stop and manually feed the line, making it more convenient and efficient to use.
Locating the Bump Head
The bump head is located at the end of the trimmer shaft, where the trimmer line exits. It is typically made of a durable plastic material and has a spring-loaded mechanism that allows the line to be advanced when the head is tapped.
Operating the Bump Head
To advance the trimmer line using the bump head, follow these steps:
- Ensure that the trimmer is running at full speed.
- Hold the trimmer upright and gently tap the bump head on the ground.
- The spring-loaded mechanism will automatically advance the trimmer line by a small amount.
- Repeat steps 2-3 as necessary until the desired line length is achieved.
Note: It is important to tap the bump head gently to avoid damaging the mechanism. Excessive force can cause the spring to break or the bump head to become loose.
Preparing the Trimmer for Head Bumping
Choosing the Right Trimmer Line
The diameter of the trimmer line is essential for proper head bumping. Use a 0.080-inch line for optimal performance and durability. Avoid using thicker lines as they may reduce the trimmer’s efficiency and increase the risk of head bouncing.
Inspecting and Cleaning the Trimmer Head
Before head bumping, make sure the trimmer head is clean and free of debris. Inspect the head for any damage or wear. Use a brush or compressed air to remove any accumulated grass or dirt. Check that the trimmer line is properly installed and has the appropriate length for head bumping.
Adjusting the Trimmer Head and Bumping Release
To prepare the trimmer for head bumping, adjust the tapping force to suit your preferences and ground conditions. Most trimmers come with a bump cap and bumper spring that can be adjusted to control how easily the trimmer line releases when you tap the head on the ground. A firmer setting will require more force to release the line, while a looser setting will release the line more easily.
| Adjustment Option | Description |
|---|---|
| Bump Cap | Adjusts the tension on the bump cap, making it easier or harder to release the line. |
| Bumper Spring | Adjusts the tension of the spring that releases the line when the head taps the ground. |
By properly adjusting these settings, you can optimize the trimmer’s performance for head bumping and achieve a consistent cutting height.
Selecting the Appropriate Bump Head Line
Greenworks 21362 bump head takes 0.095 inches to 0.105 inches lines. The correct line diameter to use depends on the desired cutting thickness. Thicker lines will cut through thicker vegetation, while thinner lines will provide a cleaner cut for finer grass. It is important to choose the correct line diameter for the job at hand to ensure optimal performance.
Line Diameter Recommendations
The following table provides recommended line diameters for different cutting tasks:
| Cutting Task | Line Diameter (inches) |
|---|---|
| Light trimming | 0.095 |
| Medium trimming | 0.100 |
| Heavy trimming | 0.105 |
Installing the Bump Head Line
The Greenworks 21362 bump head line is easy to install and replace. Follow these simple steps:

Maintenance Tips for the Bump Head

Uneven cutting can be caused by several factors. Check the following:
– **Line Length:** Ensure that the trimmer line is not too long or too short.
– **Line Tension:** Adjust the line tension by turning the dial on the bump head.
– **Spool Alignment:** Make sure that the spool is aligned correctly within the head.
