Buyer’s Guide

Instructions on How to Load a Grease Gun

Before loading your grease gun, make sure that the grease you have selected is compatible with your specific tool. In case it is too thick or too liquid, it can break or simply won’t work. It is also important to avoid blending two types of grease together, as they may not mix well and could potentially damage both the tool and the grease, resulting in wasted materials.

The grease gun loading isn’t a hard process even if you have never done this before. However, it’s very important to strictly follow the instructions if you want the process to be quick and trouble-free. Follow our step-by-step manual.

  1. Detach the cartridge. This kind of tool has a two-part construction: the first part includes a cartridge with grease, and the second one includes barrel and cap with a nozzle. Detach the cartridge by unscrewing the cap. When loading your grease gun, turn the barrel clockwise while rotating in the opposite direction. It may require some physical strength to properly load the grease.
  2. Remove the metal rod. It’s used to exert pressure on the cartridge, forcing the lubricant to come out. The metal rod can be found in the grease gun center, where the cartridge is located. Pull it until it comes out completely. Once the rod is extended, it should be firmly fixed.
  3. Remove the cartridge. Commonly, the construction of these devices is designed in such a way that in order to get the cartridge, the rod must be moved to the side. You will no longer need the removed cartridge, so you can safely discard it.
  4. Prepare the new cartridge for installation. Before loading a new grease cartridge, it is important to remove any residual grease from the previous cartridge. This can be done by wiping the barrel clean with a dry cloth or rag. Remove the cap from the new cartridge. Note that if the cartridge has been stored upside down, the grease will accumulate on the right side. If it has been stored in the standard position, shake it several times before installation in order to make the grease settle in the right direction.
  5. Install a new cartridge. That part of the cartridge that had a cap on it should be located in the front. The end of the cartridge with the seal must fully coincide with the end of the barrel.
  6. Assemble the grease gun back. Unblock the rod and press it to the barrel. At the same time, you need to press the handle of the nozzle to get rid of air in the barrel. When using your grease gun, it is important to stop pressing the trigger immediately after the grease appears from the nozzle to prevent over-lubricating the part or creating a mess. Attach the barrel and the head by rotating them in the opposite directions. Remember not to screw too tight, it will cause a pressure drop in the tool, making it impossible to use.

Make sure that the grease is delivered by pumping the handle.

Guide on How to Use it

When using a grease gun, you shouldn’t forget about safety measures:

  1. Don’t apply lubricants to a running vehicle.
  2. You should always maintain proper footing and balance to make it easier to control your device in unexpected situations.
  3. It’s better not to let the lubricant get on your skin, especially if you have any wounds because all lubricants have a certain level of toxicity. Wash your hands after you finish working with a tool.
  4. Check the hose before each use. If it’s damaged or worn out, it may rupture causing fingers or hands injury.
  5. The pneumatic and electric grease guns can create extreme pressure that is insensible to the user. Therefore, be careful when working with these kinds of tools.
  6. Electric grease guns require special safety measures to ensure proper use and avoid accidents. It is important to turn off the gun before inserting the battery, and to keep the tool away from water and any metal objects that could cause a short circuit.
  7. Make sure to read the instructions provided by the manufacturer.

To start using the tool, place the coupler directly on the area to be greased and press the handle several times at that moment when you need the grease to begin flowing. The harder you push the handle, the more powerful jet of lubricant fluid you will get. Note that the hand-powered grease guns will make you put some effort, but the electric tools and tools that use an air compressor provide an increased working pressure and feed rate, so be careful.

Don’t neglect cleaning your device after each use. Having dried grease inside, it will start causing troubles and become unusable over time (or at least difficult to use).

Benefits of Using

Of course, the quality of lubricant is important, but the improper tool for lubrication can also cause some issues. That is why you should be attentive when choosing the one. There are a bunch of reasons why grease guns are considered to be one of the most effective and reliable tools for lubrication:

  • Accuracy of application. Thanks to its long and flexible tube, these tools is especially convenient to accurately lubricate hard-to-reach areas. Plus, some models allow changing different kinds of nozzles to carry out various types of lubrication.
  • Convenience. If you prefer smaller and more compact garage tools, you might consider a grease gun with a 3 oz cylinder capacity, which is perfectly sized for one-handed operation.
  • Grease waste prevention. Devices supplied with the flow meter allow controlling the amount of grease being used. This helps avoid damage to the bearings due to excessive or insufficient lubrication. So, thanks to the ability to measure the adequate amount of lubricant, it prevents grease spills and wastes.
  • Cost-efficiency. In relation to preventing spills and wastes, this tool will help you save some money on buying grease, oils, and lubes.
  • Longevity. Based on actual users, the grease guns have durable built and structure that is enough to last for more than a decade.
  • Reliable lubrication. The grease gun delivers lubricant under pressure, ensuring that all car parts receive adequate lubrication.

How to Choose the Best Grease Gun

Actually, these devices have approximately the same working principle: the pressure is pumped in the cylinder due to the reciprocating action and the lubricant is squeezed out through the rod by a piston. When high pressure is reached on the nozzle, a lubricant enters the hose via an open valve.

If you require a tool that can efficiently lubricate car parts that are exposed to heavy loads and prone to rapid wear and tear, a grease gun should be considered. However, the choice of the right tool can be confusing because the modern market offers a great variety of different types and models. With our help, you can get the best mini grease gun for convenient home use or large, heavy, and powerful model for your workshop. So first, let’s take a look at their types so you will be able to find out which one of them is suitable for you.

  • Hand-powered
  • The manual grease guns include lever, screw-type, push-type, suction, and pistol-grip models. Grease guns are designed for both professional and home use and are popular due to their budget-friendly and safe usage.

  • Electric
  • Such models are powered via a cord or by a rechargeable battery. Thanks to that, they are more convenient in use as you don’t have to put much pressure manually.

  • Air-powered (pneumatic)
  • These devices use compressed air. It’s more suitable for commercial use as it’s difficult in usage and can be dangerous for a non-professional. However, it’s powerful enough to be used with very thick greases at low temperatures.
