What Are the Must Have Features to Consider Before Buying the Best Mini Grease Gun?
Whether you are looking for a mini grease gun for air tools or a car grease gun, no matter which type of small grease gun you need, you can't be sure about its quality or performance from the outer appearance, star ratings, or brand value.
To understand the quality and compatibility of the gun with your project, you need to scrutinize its key features. If you are not sure which features to look for, here is your chance to learn them all.
In this section, I am going to discuss some of the essential features that your targeted small grease gun must have.
Type
First of all, you need to be aware that there are various types of grease guns available in the market. Some are small manual grease guns, air-operated grease guns, corded and cordless grease guns, pump-based guns, and pistol grip guns. So, choose the type that feels comfortable to use for your project.
Size
Even though you are determined to purchase a small grease gun, size is still an important factor to think about. If the gun is small but not easy to grip in your hand, then it won't be comfortable. So, be mindful of the grease gun size.
Ergonomic design
Depending on the project type, you are going to use the mini grease gun kit for quite a long duration. Hence, having an ergonomic design for the gun is essential; otherwise, your hand might feel fatigued for a long time. Also, an ergonomic small grease gun will ensure comfortable use, quick and precise application on the surface effortlessly.
Power
A grease gun's pressure output is expressed as PSI (pounds per square inch). Usually, it ranges from 3000 PSI to 10000 PSI or more. If the PSI is too low, it won't be suitable for large elements. Thus, choose the correct PSI considering the components you are going to lubricate.
Hose Length
If you are using the mini grease gun in an indoor garage, then most likely, you will need a gun with a hose. The hose length also varies depending on the model. According to your convenience, you can choose hose length from 18 inches to 42 inches
Cartridge Capacity
The capacity of mini grease gun cartridges is another important feature to consider. If the capacity is high, then you don't need to refill it frequently. The 14 oz grease gun is a standard mini grease cartridge capacity most users use for professional and DIY projects.
Durability
Since you are going to use micro grease guns for regular use, you must make sure the device is made strong and durable. While checking the build quality of the gun, you should check whether it leaks while passing lubricant through the nozzle. The leakage-proof grease guns come with metal barrels, tight-fitting barrel heads, top-quality seal, and hardened plungers.
Ease of Use
Mini grease guns are handy, portable, and need to be used regularly. Thus, it's important to ensure that the gun is user-friendly and easy to use. Considering your purpose of using a grease gun, user experience, and how frequently you are going to use it, you should choose the right kind of grease gun.
If you are a beginner, then you can go for a hand lever grease gun as it is easy to use and control. Then, the pneumatic grease guns are less portable; thus, the device should be attached with an air compressor to control the grease flow easily.
Nevertheless, the battery-powered grass guns are heavy and difficult to carry. So, considering the different kinds and functionality, you should choose the one that is easy for you to use.
Budget
Mini grease guns aren’t much expensive. You can get good quality guns from $12 to $40. However, you should check if the price is compatible with the build quality and performance. Then only you can choose the gun which is worth the money.
How to Load a Mini Grease Gun?
Though there is a wide variation in grease guns, the loading mechanism is more or less the same. Here is a quick detail about how to load a mini grease gun. If you follow the below steps, you can load the gun effortlessly.
There are three loading options a mini grease gun can offer, such as bulking, suction and cartridge. Compared to the three, the bulking method is suitable for hand-lever guns that have a small barrel. Though the method might seem simple, it is time-consuming and creates a lot of mess while filling the gun with lubricant. It would help if you used a putty knife and gloves to insert grease into the barrel.
Then, the suction method is the reverse method of the usual grease gun filling mechanism. First, you need to remove the head barrel. Then, position the opened barrel in the grease pot and pull the plunger rod. This way, it will generate suctioning of the grease into the barrel.
Compared to the three methods, the cartridge is the easiest and clean way to load a grease gun. You just need to remove the old one and replace it with a new one. The gun is ready to use. However, they are expensive too.
How to Use Mini Grease Gun?
No matter which mini grease gun you choose for lubricating the components, the using procedure is more or less the same. Before you follow the below steps, you should always refer to the manual instruction that comes with the package. Just for a general understanding, here I am sharing the using mechanism of a grease gun.
Step 1
First of all, you need to set up the grease gun before using it. Remove the parts from the package and assemble them if needed.
Step 2
In the next step, you need to load the cartridge. If you have an old cartridge, you need to remove it from the device first. Here, you need to follow the manual instruction to disassemble it from the device.
Step 3
After removing the old cartridge, you need to insert a new one. Just take the new cartridge and insert it into the designated spot. You might experience a bit of lubricant spill. Don't worry! Just clean up the grease and screw the nozzle. Make sure it is not too tight or too loose.
Step 4
This step is very important. As you insert the cartridge, the chances are that the device will get some air bubble. If it happens, you need to bleed the air properly. Some guns have a self bleeding mechanism. However, the manually operated mini grease guns need to do the job using hand pushing down the piston rod.
So, you need to follow the steps that the device suggests. However, make sure the air is completely removed and tighten the bleeding nipple.
Step 5
After cartridge insertion is complete, you are now ready to use the device for lubrication. All you need to do is remove the dust cap, clean in, and position the nozzle over the nipple. Make sure the nozzle is properly set in the position. Then, keep pumping the grease till you get adequate flow from the rubber boot.
Step 6
After greasing is complete, you need to clean up the leftover grease. Wipe them away with a rug and warm water, change the nipple dust cap and store it in a secure place.
