Take a new DeWalt-compatible grease cartridge and remove the plastic end caps. Carefully insert the cartridge into the grease gun, ensuring that the plunger fits snugly against the cartridge. -
Reassemble the grease gun:
Slide the barrel or assemble the head back onto the grease gun, securing it in place by locking the handle, just like it was before.
Step 3: Bleeding the Grease Gun
Now that your grease gun is loaded and ready, it’s time to bleed it.
-
Point the nozzle away from your body:
This is critical for safety. Direct the nozzle to the side or downward, away from yourself or any bystanders. -
Pull the trigger slowly:
As you pull the trigger, watch for the grease to start flowing out. Initially, air may release before grease appears, which is entirely normal. -
Continue to pump:
Keep pulling the trigger in short intervals. You may need to pump several times to expel the trapped air. Every few pumps, check the grease flow. Once you see a smooth, consistent flow of grease without air bubbles, the gun is successfully bled. -
Check for grease at the nozzle:
To ensure effectiveness, confirm that grease is dispensing correctly and evenly from the nozzle.
Step 4: Clean Up
After bleeding your grease gun, make sure to wipe down the nozzle and surrounding areas to remove any excess grease. This step not only keeps your workspace tidy but also prevents dirt and debris from contaminating your grease.
Common Issues and Troubleshooting
Despite following the above steps, you might run into some issues. Here are some common problems and solutions when bleeding a DeWalt grease gun:
Stubborn Air Pockets
If you are experiencing stubborn air pockets that won’t expel, try these methods:
- Re-check the cartridge: Ensure the cartridge was installed correctly and has not been punctured.
- Use a different technique: Instead of only pulling the trigger, try to apply a little more pressure to the handle while triggering. This additional pressure can help push out the air more effectively.
Inconsistent Grease Flow
If the grease gun dispenses grease inconsistently, consider the following:
- Check for clogs: Examine the nozzle and any attachments for blockages that might restrict grease flow.
- Inspect the grease: Sometimes, thick or old grease can cause issues. Always use fresh, compatible grease for your particular application.
Maintaining Your DeWalt Grease Gun
While bleeding your grease gun is vital, regular maintenance goes a long way in ensuring that your tool remains functional. Here are some tips for ongoing care:

What is bleeding a grease gun, and why is it necessary?
Bleeding a grease gun involves removing air pockets from the grease cartridge which can create pressure issues during operation. When air is trapped inside the gun, it can prevent the proper flow of grease to the application point, which can lead to insufficient lubrication. This process ensures that the grease flows smoothly and efficiently, allowing for optimal performance.
Moreover, regular bleeding of your grease gun can extend its lifespan and enhance its reliability. When air bubbles are present, they can lead to inconsistent dispensing and may even cause the gun to malfunction. By properly bleeding your grease gun, you can maintain the integrity of your tools and ensure that machinery stays well-lubricated.
How do I know if my DeWalt grease gun needs bleeding?
There are a few signs that indicate your DeWalt grease gun may need bleeding. One of the most common indicators is erratic or inconsistent grease flow; if the grease spurts out in bursts or fails to come out at all, it means air may be trapped inside. Additionally, if you notice a decrease in the pressure or resistance when pumping the grease gun, it’s a clear signal that it needs attention.
Another sign is the presence of air pockets that can be identified visually. If you open the grease gun and see bubbles or any separation between the grease and the cartridge, it’s time to bleed the unit. Taking the time to assess the gun regularly can prevent further complications down the line.
What tools do I need to bleed my DeWalt grease gun?
Generally, the tools needed to bleed a DeWalt grease gun are quite minimal. Usually, all you require is the grease gun itself, ideally the model with a manual bleed valve or an API (automatic pressure indicator). In some cases, having a clean rag or paper towel on hand can be beneficial for cleaning off excess grease after the process.
If your grease gun lacks a dedicated bleed valve, a small flathead screwdriver may be helpful to remove the grease cartridge cap. This can allow for the release of any trapped air. Regardless of tool specifics, creating a clean work environment is important to maintain hygiene and prevent contamination of the grease.
Can I bleed my grease gun without removing the cartridge?
Yes, it is possible to bleed a grease gun without completely removing the cartridge. Most DeWalt grease guns come equipped with a manual bleed valve that allows you to release trapped air simply by pulling the trigger without the need for cartridge removal. This method is usually quicker and less messy.
However, if the air issue persists, you may still need to remove the cartridge for a more thorough inspection. Checking for air pockets at the source guarantees a more reliable and efficient operation. Following the manual for your specific grease gun can provide additional guidance on whether this is feasible.
