8 Things to Consider When Buying a Cordless Grease Gun

If you already have a standard grease gun and decide to buy another new one, you may have some idea about the important features of good quality grease gun must-have.

However, it must be hard for you to decide which one is the best as there are a lot of factors you would like to consider until you got confused.

Meanwhile, if you are a first time user and have no knowledge about cordless grease guns, you might end up choosing the wrong grease gun that does not suit you.

So, here is the guideline for all.

Battery type

To operate your cordless grease gun you need a battery. The most common types of battery use are Lithium-Ion and NiCad. So, what are the differences between these two?

Lithium-ion battery which has a flat energy output is the most recent technology for hand tools. What is mean by flat energy output? Okay, the flat energy output is the constant energy that stays in the battery until it is depleted. No decreasing of energy for the battery. So, you can use your cordless grease gun with maximum capability until the battery energy is depleted.

Meanwhile, when you using the NiCad battery, there will be a gradual reduction until the battery energy is depleted eventually. So, when you using your cordless grease gun and the battery energy reduce, it will affect your grease gun capability.

Moreover, Lithium-Ion has thrice long life services than NiCad. Even though the price of Lithium Ion is a bit expensive but it matches the features.

Working Pressure (PSI)

The ideal working pressure for a cordless grease gun (PSI) is within the range of 4,500 to 10,000. This range of working pressure is also able to blast any clogged fittings that resulted because of old grease residue, dirt and so on.

Lube Meter

Applying too much grease can cause the bearings to damage plus, wasting the grease. So here is the important function of the lube meter.

This meter will help you to measure the amount of grease that the fittings point needed. If you find a cordless grease gun with these features, you should include it in your top list!

Design

The important things about design other than versatility, elegancy and other appearance feature that you looking at, it should offer you comfort. Choosing an ergonomic design with a comfort-fit grip is compulsory especially if you doing lubricating work regularly.

You need to consider several factors such as; when you insert the battery into the grease gun, the weight will add so it may bring un-comfort for you to hold the grease gun for long hours. So here is the importance of ergonomic design (other than choose the lightweight grease gun), to prevent your hands from cramping.

Choose the grease gun that is easy to hold and balance to reduce arm/wrist pain. It is a bonus if you can find the one with a design that is made to rest on the flat surfaces while in use. It will help you to reduce hand fatigue.

LED

A cordless grease gun that comes with LED is highly recommended! Sometimes even most of the time you will need it as locating the grease fittings is very challenging. This feature will speed up your work and help you see the grease fittings effortlessly.

Hose

Lubrication usually does not happen in open spaces. If you observe, most spaces to grease are hard-to-reach, tight and non-accessible.  The presence of a hose will give you a solution to this problem. Hose with flexibility is highly needed to reach the hard spot.

With the perfect length of hose (27 inches above) you can grease happily the tight spot. So, choose a flexible hose with a long length to ease your work.

If there is a spring at the tip of the hose with a non-drip cap, yes that’s the perfect one!

Cartridge Capacity

Refill the cartridge over and over again will make you annoyed and tired. You need to go through the messiness again and again.

So, choosing a big volume and high capacity of the cartridge is important to make your workflow smoothly.

The ideal capacity is around 14 oz. cartridge. This will be more than enough to hold a high volume of grease at one time.

Warranty

When buying something especially tools, you need to check either they provide the warranty, the duration of the warranty, the aspects that they cover when the tools damage and so on.

As a user, for sure we hope that the things we buy will last long. So make sure you already consider the important feature that a good grease gun must have before purchasing as you should buy the best one only that comes with a warranty in case something unwanted things happen.
