You should remove the old grease and then refill the grease gun. You will have to keep the piston in the correct position after securing it and remove the old cartridge after changing the piston’s position.
  4. Insert the new grease: Here comes the most important step in loading the grease gun. First of all, clean the grease gun properly. You can use the old cloth, tissue paper, or anything else to clean it up. If you are sure that the grease gun is ready for refilling then move ahead. Make sure that the grease is compatible with the grease gun and suitable for your job. You should read the manual or guidelines available with the grease gun before purchasing the cartridge. Open the new cartridge from one end and insert it into the grease gun. Remove the plastic head from the new cartridge for quick processing.
  5. Screw the grease gun: Now reattach the end cap to the grease gun. Do not exert much force while screwing and maintain a balance. It is better to remove the extra air from it. Also, unlock the piston rod which you secured in 3rd
  6. Test the grease gun: In the final step, we have to test the grease gun by lubricating any of your machines. Check whether it is delivering enough lubricant or not. You may need to recheck the device if its delivery pressure has become less than what it was before.

  2. Fill the barrel: Now you have to fill the barrel by putting its distal end inside the grease holder. The grease holder should be holding the grease.
  3. Remove the barrel from the container: Remove the barrel from the grease container after the withdrawal of the plunger rod. Rotate the barrel to remove the excess grease if available. It is compulsory to remove the end of the barrel.
  4. Screw and assemble the grease gun: Reattach the nozzle, cap, piston rod, and other parts that you removed in the first step. Assembling has to be performed carefully. Now clean the grease gun with a rough cloth and store it.
  5. Testing: In the end, do not forget to test the grease gun. In a case, you found any issue, you will be there to fix it. Also remember, if the grease gun is not delivering the amount it used to deliver before, there might be some issue with that.

Tips to Use a Grease Gun:

Here are a few things you need to understand to get improved and efficient work from the grease gun.

  • Use a piece of cloth or tissue paper to clean the debris from the grease gun. Also, clean its nipple and coupler after use.
  • Inspect the grease fitting more often and replace it if found damaged.
  • Keep the grease gun clean and store it on a clean surface.
  • You should keep the grease gun safe/covered when it is not in use.
  • Many grease guns have a delivery pressure of 15,000 PSI. It is better to take care of the damages caused by the leakage. So, store it away from other tools.
  • To increase the life of the coupler, remove the extra grease from it.
