How to properly use a grease gun

A grease gun is a valuable tool in the arsenal of maintenance professionals, allowing for precise lubrication of bearings, gears, and other critical components. However, using a grease gun correctly is essential to ensure that lubrication is effective and reliable. In this article, we'll guide you through the steps for properly using a grease gun, helping you maintain your machinery's peak performance and extend its lifespan.

Step 1: Choose the Right Grease

Before you begin, ensure you have the correct type of grease for your application. Different machinery and components may require specific types of grease, so consult manufacturer recommendations or lubrication guidelines. The wrong grease can lead to inadequate lubrication or even damage to your equipment.

Step 2: Prepare the Grease Gun

  • Load the Grease: Open the grease gun and load it with the appropriate grease. Ensure that the grease is clean and free of contaminants.

  • Prime the Grease Gun: To remove air from the grease gun's barrel and ensure a continuous flow of grease, prime the gun by pumping the handle until you see grease emerging from the nozzle.

Step 3: Locate the Lubrication Points

Identify the lubrication points on your machinery. These are the areas where grease needs to be applied. Refer to equipment manuals or lubrication diagrams if necessary.

Step 4: Apply the Grease

  • Attach the Nozzle:
    Affix the appropriate nozzle to the end of the grease gun. The nozzle should fit snugly onto the lubrication point.

  • Pump the Grease: With the nozzle securely in place, begin pumping the grease gun's handle. Apply grease in small, controlled amounts to prevent over-lubrication.

  • Observe Lubrication: As you pump the grease, keep an eye on the lubrication point. You should see fresh grease emerging and displacing old or contaminated grease.

Step 5: Clean and Store the Grease Gun

After lubricating your equipment, clean the grease gun and nozzle thoroughly to prevent contamination and maintain its longevity. Store the grease gun in a clean, dry place, and secure it to prevent damage or accidents.


Properly using a grease gun is a fundamental skill for any maintenance professional. By choosing the right grease, preparing the gun correctly, identifying lubrication points, and applying grease with precision, you can ensure reliable lubrication, reduce friction, and extend the lifespan of your machinery. Regular and effective lubrication not only enhances equipment reliability but also contributes to overall operational efficiency and cost savings. Mastering grease gun techniques is an investment in the longevity and performance of your machinery.
