Proper disposal of old grease is essential; check local regulations on disposal methods.
Step 4: Clean the Grease Gun
Cleaning the grease gun is an important step in ensuring that all contaminants from the old grease are removed.
- Use a clean cloth or paper towels to wipe down the inside of the grease reservoir and the fitting.
- For tougher residue, a plastic scraper or wire brush can help remove stubborn grease chunks.
Step 5: Insert the New Grease Cartridge
Once your grease gun is clean, it’s time to insert the new grease.
- For Manual Grease Guns:
- Slide the new grease cartridge into place.
-
Screw the end cap back on securely.
-
For Cordless Electric Grease Guns:
- Slide the new cartridge into the chamber.
- Close and lock the chamber according to the manufacturer’s design.
Ensure you are using grease that is compatible with your DeWalt grease gun. Check your manual for recommended types.
Step 6: Prime the Grease Gun
After inserting the new grease cartridge, you need to prime the grease gun to get the fresh grease into the nozzle.
- For Manual Grease Guns:
-
Pull the handle slowly until you see grease coming out of the nozzle.
-
For Cordless Electric Grease Guns:
- Press the trigger to allow the new grease to flow into the nozzle until there are no air bubbles.
This step ensures the new grease is ready for use and functions correctly.
Step 7: Test the Grease Gun
Now that you have completed changing the grease, it’s time to test the functionality of your grease gun.
- Activate the grease gun by pressing the trigger and checking for smooth operation.
- Inspect the nozzle for an even flow of grease, indicating correct priming and lubrication.
Step 8: Regular Maintenance Tips
To extend the life of your DeWalt grease gun, consider implementing these maintenance tips:
- Regularly check and change grease based on usage frequency. For heavy use, consider every month, while less frequent use may require checks every 3-6 months.
- Keep your grease gun clean and free from debris.
- Store your grease gun in a dry place to prevent rust and corrosion.
Troubleshooting Common Issues
Sometimes, despite meticulous care, you may encounter issues with your DeWalt grease gun. Here are common problems and troubleshooting steps:
Poor Grease Flow
- Cause: May indicate that the grease has hardened or that the grease gun needs to be primed again.
- Solution: Check the grease cartridge and repeat the priming process to remove air pockets.
Leakage from the Nozzle
- Cause: Could be due to damaged seals or an improperly installed cartridge.
- Solution: Inspect seals for damage and ensure everything is fitted correctly.

What type of grease should I use in my DeWalt grease gun?
The type of grease you should use in your DeWalt grease gun largely depends on the application and the specifications provided by the manufacturer. Generally, lithium-based or multi-purpose greases are recommended for various types of machinery and tools. For best results, check your DeWalt tool’s manual and make sure that the grease meets the necessary performance requirements.
Additionally, consider the working environment while selecting grease. If the equipment is exposed to extreme temperatures or heavy loads, you might need a specialized grease designed for high-pressure or high-temperature applications. Ensuring the right type of grease is critical for optimal performance and longevity of your tools.
How often should I change the grease in my DeWalt grease gun?
Changing the grease in your DeWalt grease gun depends on usage frequency and the type of projects you undertake. Generally, if you use your grease gun regularly, it is advisable to change the grease every few weeks to ensure it maintains its performance. Heavy-duty applications may require more frequent changes, while light usage may allow for longer intervals.
It’s important to observe the consistency and appearance of the grease. If it appears dirty, thickened, or has an unusual smell, it’s time to clean and replace it. Regular maintenance ensures that your tools and machinery operate smoothly, reducing wear and tear over time.
What are the steps to properly change grease in a DeWalt grease gun?
To change the grease in your DeWalt grease gun, start by loosening the air release valve while ensuring the gun is not connected to any power source. Next, remove the old grease cartridge by unscrewing the end of the grease gun and pulling the cartridge out. Dispose of the old grease properly, following local regulations.
Once the old cartridge is removed, clean the interior of the grease gun using a lint-free rag to remove any residue. Insert the new grease cartridge and secure it tightly. Finally, prime the grease gun by pulling the trigger until you see fresh grease coming out of the nozzle, ensuring that it’s ready for use.
Can I mix different types of grease in my grease gun?
Mixing different types of grease is generally discouraged unless you are certain they are compatible. Incompatible greases can lead to a breakdown of the grease, reduce its efficiency, and potentially cause damage to your equipment. Always consult the manufacturer’s specifications or guidelines to determine if the types you intend to mix are suitable for coexistence.
If you suspect that mixing has already occurred, it is best to clean out the grease gun thoroughly and replace it with a single, compatible type of grease. This helps you avoid any chemical reactions and ensures the performance remains optimal.
Is it necessary to clean the grease gun before changing grease?
Yes, cleaning the grease gun before changing the grease is essential for maintaining optimal performance. Residual old grease can become contaminated over time, affecting the efficiency of the new grease you plan to introduce. Cleaning removes any dirt, moisture, or degraded grease that could compromise the functionality of your grease gun.
To clean your grease gun, disassemble it carefully and wipe down all parts with a clean, lint-free cloth. Make sure to pay close attention to the grease fittings and nozzle to ensure no old grease remains. Proper cleaning will help in maintaining the effectiveness of your grease gun and prolong its lifespan.
What should I do if my grease gun gets air-locked?
If your grease gun becomes air-locked, the first step is to release any built-up pressure. Make sure the gun is not connected to a power source and then loosen the air release valve. This should expel any trapped air, allowing grease to flow freely when you pull the trigger again.
If the problem persists, you may need to perform a more thorough priming of the grease gun. To do this, remove the nozzle and pull the trigger until grease flows without interruptions. This process helps to expel any remaining air pockets. Always remember to follow up with regular maintenance to minimize the chances of air-locking in the future.
