Things to Consider When Choosing Cordless Grease Guns
The Amount Of Grease Produced: When buying grease guns, it’s important to know how much pressure it operates under. The pressure can dictate the conditions under the gun is suitable for use. Large scale grease gun users, especially those who use it for commercial purposes, will prefer guns that use more pressure to produce more grease. On the other hand, small scale users (including at-home users) will go for low-pressure guns.
Battery Capacity: We’re looking at cordless guns, so we have to be keen on how long their batteries will last while in use. The more they’ll last, the better. For large-scale users, guns with even more battery capacity are the best. You should also be keen on the time it takes for the battery to charge (if it’s a rechargeable one). If they’re replaceable batteries, check on their availability.
Size: The size of a cordless grease gun has many significances. One, it determines the amount of grease that it can hold. Larger sizes will keep more grease; thus, less frequency of loading more grease onto it, and vice versa. However, size also determines portability. If you need a grease gun to use on a journey, you’ll need a small-sized one.
Price: Price and purpose go hand in hand. A grease gun with additional features will cost more. It’s upon you to decide what you need the gun for. It won’t help to purchase a large, high-capacity, high-pressure grease gun at a high cost, yet you only need a small and portable one for your bicycle. So, know your purpose and budget appropriately.
Comfort: Already, these are cordless guns, so the amount of work you’ll be doing to operate them is little. However, there are additional features that can determine how comfortable to use they are. For example, the handle grip should be both soft and non-skid. Rubber handles are preferable for these two features.
Other Factors: You may also want to consider additional features that may include the gun’s color, warranty information, and more. Most of the grease guns on my list come in a variety of colors to give you multiple choices to choose from. Most have also been warrantied to mean that their manufacturers have invested a lot of trust in them. Be sure to check all these factors, too.
Conclusion
Using the appropriate grease gun will help you achieve top-notch lubrication requirements of your machines, hence optimal performance. The best cordless grease guns lead the way to excellent lubrication, especially given that they’re straightforward to use for reaching your machine’s “hidden spots.” Your greasing activities aren’t going to be messy again — not when you have one of the Top 8 Best Cordless Grease Guns on this list.
