How to Change a Grease Gun Cartridge: A Step-by-Step Guide
As a mechanic, carpenter, or DIY enthusiast, you rely heavily on your trusty grease gun to lubricate and protect your equipment, tools, and moving parts. However, it’s essential to know how to change a grease gun cartridge to ensure optimal performance and extend the life of your tool. In this article, we’ll guide you through the process of changing a grease gun cartridge, highlighting the importance of proper maintenance and troubleshooting common issues.
Why Change a Grease Gun Cartridge?
Before we dive into the process, it’s crucial to understand why changing a grease gun cartridge is essential. Here are some reasons why:

• Contamination: Grease gun cartridges can become contaminated with dirt, debris, or other substances, which can compromise the quality of the lubricant and affect tool performance.
• Expiration Date: Grease gun cartridges have an expiration date, beyond which they may not meet the manufacturer’s specifications, compromising the performance and reliability of your tool.
