What Are the Must-have Features to Find the Best Cordless Grease Gun? 

Whether you choose an electric grease gun or cordless battery-powered grease guns, picking just one gun out of thousands can sweat you out. Each gun promises to have outstanding features and performance that anyone can get carried away. Thus, it's extremely important to closely look at some of the key features to identify the heavy-duty ones from them.

Below are some of the features you surely shouldn't miss!

Build quality

The efficiency of a grease gun will depend a lot on its build quality. To understand how strongly the device is constructed, you need to look into the design as well as the material. Some heavy duty pistol grip style grease guns are easy to use and come with steel material. It gives the assurance to last. So, check out the material and design for durable build quality.

Motor 

Motor capacity is one of the most significant factors you must consider. A strong grease gun should have the capacity to reach hardly reachable areas and remove the block of the machine. A machine can be blocked with dust, dirt, sticky grease, concrete, and so on. To pass through such heavy components, a grease gun should have motor power with a capacity of 4500 to 10,000 PSI.

Battery

If you are fond of battery-operated grease guns, then remember the device can run smoothly with a powerful battery. It reduces the necessity of charging frequently and you can carry it on any outdoor projects. Such smooth operation is with a Lithium-ion battery. Another benefit of having a Rechargeable Grease Gun is, it makes it convenient and easily portable.

Performance

The performance of a grease gun will depend on the run time of the device once charged. Usually, a good quality grease gun can be used up to 20 cartridges. If the capacity is low, you will have to charge it again and again.

Hose 

Always make sure your chosen grease gun has a long and flexible hose. As you are going to work on diverse types of projects, the device needs to reach the targeted spots. Hence, the hose length should be long enough and easy to reach. Additionally, if the hose can be used from different angles, it would make the device much more user-friendly.

Grease flow

Another key factor is, how the device applies the grease. Devices that are of medium outflow are better than heavy flow because heavy flow can damage the machine. Nevertheless, the low outflow will not be able to remove the block easily and quickly. So, choose medium grease flow.

How to Use a Cordless Grease Gun?

From air operated grease guns to battery-powered grease guns, there is a wide range of grease guns available in the market. Though the application of the grease is quite similar for most devices, it's important to follow the manual instruction before using. Since cordless grease guns are very popular these days, here I would like to briefly discuss how to use this device.

Step 1: 

Arrange the things you will need to use the grease gun. To run a cordless grease gun, gather a clean rag, a grease gun, cartridge, and so on.

Step 2:

Before operating the device, you need to load the cartridge. If you already have a loaded cartridge from previous use, unscrew the front cap near the nozzle and remove it. Follow the machine mechanism to remove the cartridge. Mostly cordless grease guns come with a handle to operate the piston rod at the back of the gun. Pull it back to remove the grease and wipe the residue.

Step 3:

It's time to insert the new cartridge. Take the new cartridge, open it and insert it into the device. When insertion is complete, remember to wipe away the grease that seeped through. Then screw the nozzle up but make sure it's not too tight.

Step 4:

After you are done loading the cartridge, make sure to bleed the air from the device. Some devices are self-bleeding, but devices that need manual bleeding should follow the instruction manual. For manual bleeding you need to push down the piston rod, lock it in position and push the rod pumping the grease. Once the entire air is removed, fasten the bleeding nipple.

Step 5: 

As your device is ready with the cartridge, it's time to use it on machines. First of all, you need to remove the dust cap and clean it properly. Then, set the grease nozzle over the nipple and press it down on the nozzle until it's properly set into position.

Now, start pumping the grease till you notice adequate flow where there is a rubber boot. Once you are done greasing the machine, wipe away the residue and change the nipple dust cap.

Step 6:

While you intend to store the gun after use, make sure to clean it with warm water.
