Operating and maintaining machinery, equipment, and vehicles is not always convenient, especially for those who need to fix a problem immediately. Fortunately, manual lubrication devices like cartridge grease guns make it easier to apply lubricants directly to hard-to-reach areas and fittings. If you’re new to using a cartridge grease gun, it may seem like a daunting task. Fear not, because loading a cartridge grease gun is a remarkably simple process that can be completed in four straightforward steps. Getting the hang of it may take a couple of tries, but follow these detailed instructions closely, and you will be well on your way to becoming a pro.
Firstly, always start by inserting the cartridge into the gun. Ensure that the cartridge is compatible with your grease gun; not all cartridges are created equal. Once the cartridge is securely in place, grab the handle of the gun firmly with one hand and the end cap of the cartridge with the other hand. Pull back on the end cap with a smooth, even motion as if you were removing the top off a soda can. Be careful not to pull too hard, as this could damage the cartridge. With the end cap removed, the grease is now ready to be dispensed.
Next, locate the air bleeder valve on the gun. Usually, this is a small screw that is located near the front of the gun. Loosen the bleeder valve slightly to allow any trapped air to escape from the gun. Tighten the bleeder valve back up once all of the air has been released. Releasing the trapped air will help ensure that the grease flows smoothly and consistently. Now, you can begin applying the grease by attaching the coupler of the gun to the zerk fitting on the component or machinery that needs lubrication. Pump the handle of the gun in a smooth, back-and-forth motion to dispense the grease. Continue pumping until you see fresh grease coming out of the zerk fitting. Stop pumping and disconnect the coupler from the zerk fitting.
Introduction to Cartridge Grease Guns
Cartridge grease guns are a type of grease gun that uses pre-filled cartridges to dispense grease. They are typically used for applications where a high volume of grease is needed, such as in automotive and industrial settings.
Cartridge grease guns are relatively easy to use. To load a cartridge, simply insert the cartridge into the gun and twist it until it clicks into place. Once the cartridge is loaded, you can begin dispensing grease by pulling the trigger.
There are a few different types of cartridge grease guns available. The most common type is the manual grease gun. Manual grease guns are operated by hand, and they are typically used for small to medium-sized jobs. Air-powered grease guns are another option. Air-powered grease guns are more powerful than manual grease guns, and they can be used for larger jobs.
When choosing a cartridge grease gun, it is important to consider the following factors:
- The type of grease you will be using.
- The size of the job you will be doing.
- The features you want in a grease gun.
Types of Cartridge Grease Guns
There are two main types of cartridge grease guns: manual and air-powered.
Manual grease guns are operated by hand, and they are typically used for small to medium-sized jobs. Manual grease guns are relatively inexpensive, and they are easy to use. However, they can be tiring to use for long periods of time.
Air-powered grease guns are powered by compressed air, and they are typically used for larger jobs. Air-powered grease guns are more powerful than manual grease guns, and they can be used to dispense grease more quickly and easily. However, air-powered grease guns are more expensive than manual grease guns, and they require a source of compressed air.
Choosing the Right Cartridge Grease Gun
When choosing a cartridge grease gun, it is important to consider the following factors:
- The type of grease you will be using. Not all grease guns are compatible with all types of grease. Be sure to check the manufacturer’s specifications before purchasing a grease gun.
- The size of the job you will be doing. If you will be doing a small job, a manual grease gun may be sufficient. However, if you will be doing a large job, an air-powered grease gun may be a better choice.
- The features you want in a grease gun. Some grease guns have features such as adjustable pressure settings, built-in LED lights, and ergonomic handles. Consider which features are important to you before making a purchase.
Choosing the Right Cartridge for Your Gun
If you are unsure which cartridge to use with your gun, there are a few factors to consider:
Viscosity:
The viscosity of the grease is important for determining how well it will flow and lubricate your equipment. Low viscosity grease (e.g., NLGI 1) is suitable for light loads and high-speed applications. High viscosity grease (e.g., NLGI 3) is best for heavy loads and low-speed applications. Most cartridge grease guns are designed to handle grease with NLGI grades ranging from 1 to 3.
Operating Temperature:
The operating temperature of your equipment will also determine the type of grease you need. Grease must be able to withstand the extreme temperatures it will be exposed to without breaking down. Consult the manufacturer’s recommendations for the proper grease type for your specific application.
Viscosities and Applications
| Viscosity (NLGI Grade) | Applications |
|---|---|
| 1 | Low loads, high speeds (e.g., bearings, gears) |
| 2 | Medium loads, moderate speeds (e.g., chassis components, hydraulic cylinders) |
| 3 | Heavy loads, low speeds (e.g., open gears, mining equipment) |
Inserting the Cartridge into the Gun
Once you have selected the appropriate cartridge, follow these steps to insert it into the grease gun:
Step 1: Open the Grease Gun
Locate the release lever or handle on the grease gun and pull it back or down to open the barrel. The barrel will slide open, revealing the plunger and the internal mechanism.
Step 2: Place the Cartridge in the Barrel
Take the cartridge and align it with the open barrel. Gently push the cartridge into the barrel until it fits snugly against the plunger.
Step 3: Close the Grease Gun
Once the cartridge is fully inserted, close the barrel by pushing the release lever or handle back into its original position. Ensure that the barrel is securely closed and the cartridge is firmly held in place.
| Cartridge Size | Recommended Grease Gun Size |
|---|---|
| 14 oz | Standard grease gun with 16-ounce capacity |
| 18 oz | Heavy-duty grease gun with 18-ounce or larger capacity |
| 3 oz | Compact grease gun with less than 10-ounce capacity |
Priming the Grease Gun
Once the cartridge is loaded, you need to prime the grease gun to ensure that the grease flows smoothly through the system. Here’s how:
1. Close the Bleeder Valve
Locate the bleeder valve on the grease gun body and close it by turning it clockwise until it’s snug.
