How to Maintain Pneumatic Tools Like a Pro: Lubrication – Oil & Grease Guide
Keeping your pneumatic tools in top shape doesn’t require a mechanic’s degree — just the right know-how and a few smart tools. In this guide, we’ll walk you through the essentials of maintaining air tools like a pro, explain how to choose between oil and grease, and introduce two of M7’s most powerful solutions: the patented EZ Grease system and the bestselling NC-4255QH impact wrench.
Why Maintenance Matters for Pneumatic Tools
A well-maintained air tool isn’t just more efficient — it lasts longer, runs smoother, and reduces downtime. Regular maintenance can:
- Extend the tool’s lifespan
- Preserve torque power
- Prevent rust and corrosion
- Reduce vibration and noise
- Save on costly repairs
Whether you’re working in a garage or on a busy jobsite, knowing how to care for your tools is non-negotiable.
Lubrication : Grease vs Oil
When to Use Air Tool Oil
- Daily lubrication before and after use
- Preventing internal rust and wear
Simply add a few drops into the tool’s air inlet.
When Grease Is a Better Choice
Grease is ideal for:
- Tools with high-load parts (like impact wrenches)
- Internal components like the hammer or anvil system
- Long-term lubrication needs
This is where M7’s EZ Grease system shines.
