What mistakes should you avoid when filling a grease gun?

Lubrication that is properly done is the foundation of equipment's reliability, particularly in industries that rely on hydraulics and vehicles, heavy machinery, and agricultural machinery. A grease gun may seem like a simple tool, but using it incorrectly--particularly during the filling process--can lead to contamination, equipment failure, increased wear, and costly downtime.

If you're a maintenance technician or mechanic, or owner, knowing the most common mistakes that are made when filling an oil gun is vital to maintain efficiency and prolong the lifespan of equipment. In this blog, we'll look at the most common mistakes and ways to avoid them.

What is the reason why the proper grease gun filling matters?

Before diving into the pitfalls, it's crucial to know the reason why correct filling techniques are essential. Grease serves as a barrier that reduces friction, stopping corrosion, and preventing harmful substances. But poorly filled grease guns could introduce air pockets, dirt, or other types of grease that are not compatible, all of which could compromise the performance of lubrication.

1. Applying the wrong type of grease

The most frequently made errors are choosing the wrong type of grease to use for your particular application. Many different types of greases aren't equally. Different machines require different formulations that are based on temperature, load, and the environment.

What is the reason for this?

• Incompatible grease can be broken down rapidly
• It could fail under extreme temperatures or pressure.
• It may react negatively with existing grease.

How to Avoid It?

• Always confirm the specifications of the manufacturer.
• Use the right NLGI quality and type of base oil
• Avoid mixing different types of grease unless they are confirmed that they are compatible

2. Doing a poor job of cleaning up after filling

Contamination is the silent death knell of the lubrication system. Dust, dirt, and moisture are able to get into the grease gun when proper care is not observed.

Common Contamination Sources:

• Dirty grease cartridges
• Unusual nozzle for a grease gun
• Containers that are open to the elements

Consequences:

• Wear and tear is caused by particles of abrasive.
• A lower efficiency of lubrication
• Potential system failure

Best Practice:

• Make sure to clean all components before filling
• Place grease in containers that are sealed
• Clean hands and tools

3. The air isn't leaking from the grease gun

Air pockets within the grease gun could block the proper flow of grease, resulting in a lack of lubrication or even complete blockage.

Signals from the air Lock:

• Trigger resistance, without the output of grease
• Uneven grease discharge

The Reasons Why It Happens:

• Improper cartridge installation
• Inability to purge air following refilling

Solution:

• Always flush the grease gun following filling
• Follow the manufacturer's instructions to release air.
• Then, pump until the grease flows effortlessly

4. Filling up the grease gun

Overfilling can be a common error in the use of bulk grease. It could appear to be a good idea to boost capacities, but this could cause operational problems.

Problems caused by overfilling:

• The difficulty in reassembling the grease gun
• Internal pressure is increasing
• Damage to the seal or leakage

Prevention:

• Follow the recommended levels of fill
• Do not force grease that is too thick into the barrel.
• Make sure you leave enough room to ensure proper operation of the plunger

5. Improper cartridge installation

A wrongly installed grease cartridge could introduce air, create leaks, or even stop the grease from displacing entirely.

Common Errors:

• Do not remove both seals on the cartridges
• Incorrect alignment of the cartridge
• Failure to secure the head correctly

Tips:

• Follow the installation instructions carefully.
• Make sure that there is a secure seal between the components
• Double-check alignment before making use of

6. Combining different types of grease

Mixing greases that are not compatible is a grave error that could lead to chemical destruction or loss of capabilities.

What happens if greases are mixed

• Separation of the Thickener
• Viscosity reduced
• The formation of sludge-like substances

Avoidance strategy:

• Apply a single type of grease per application
• Mark the grease guns with a label for particular uses
• Make sure the gun is clean before switching between different types of grease

7. Inattention to the maintenance of grease guns

A grease gun needs regular maintenance. Inattention to this could lead to ineffective performance and contamination.

Maintenance oversights

• Cleaning the gun after using it
• Inattention to worn seals and damaged components
• Failure to properly store

Recommendations for actions:

• Examine your clothes frequently for damage and wear.
• Repair the component that is damaged promptly
• Keep the storage area clean and dry area

8. Equipment that is damaged or of low quality

Grease guns that are damaged or not of good quality could compromise the entire process of lubrication.

Risks:

• Pressure loss and leaks
• Inconsistent flow of grease
• Risk of contamination increases

Solution:

• Make sure you invest in top-quality grease guns
• Use tools that are not obvious signs of
• Select the right equipment for your requirements

9. Incompletely following the manufacturer's instructions

Each grease gun and type has specific guidelines. Failure to follow these guidelines could lead to incorrect filling and improper usage.

Common questions:

• The method of filling is incorrect
• Skipping air bleeding steps
• Using cartridges that aren't compatible

Best practice:

• Follow and read the instructions for use
• Inform staff about the proper procedure
• Keep documentation accessible

10. Poor storage practices

How you place your grease gun in storage and other grease products can greatly affect the performance of your grease gun.

Storage mistakes:

• The grease guns are exposed to moisture and dust
• Storing grease in unsealed or open containers
• Keeping equipment in extreme temperatures

Effects:

• Contamination
• Grease degradation
• The tool's lifespan is decreased.

Proper storage tips:

• Make sure to use protective caps on nozzles
• Store in temperature-controlled environments
• Keep containers of grease tightly sealed

11. Not completing the inspection before filling

Failure to check the grease gun prior to filling can lead to undetected issues that impact performance.
