How to Properly Use a Grease Gun?

Besides selecting the best grease gun, it is equally important that you properly handle it for the long life of the tool as well as of the machine parts. We have summed up some points to help you in that regard.

• Before using a grease gun on any of the machinery parts, calculate the proper amount of grease needed based on the calibrated delivery volume of the grease gun.
• There will be an old grease inside the bearing. To flush it out, use the vent plug on the relief port, which will reduce the risk of too much pressure on the bearing.
• Be very careful while loading the grease gun with grease that no contaminants are introduced in it. If you are using a cartridge, pay attention while removing the metal lid so no metal gets into the grease.
• Don’t load the grease gun with any other type of grease other than that with which it is identified, and make sure that the grease gun is clearly marked to identify the grease type that should go in it.
• Before greasing any part of any machine, pump out a little amount of grease from the nozzle and wipe it with the clean cloth and then only attach it to the fittings. This is to make sure that the dispensing nozzle is clean.
• Wipe the grease fittings clean before attaching the grease gun. It will be helpful to use a fitting cap but still, wipe it once.
• Always apply the proper grease at every grease point. The wrong type of grease might create an incompatibility, leading to bearing failure. To clearly identify at what points which grease to be used, the paint markers are one solution.
• For proper delivery of volume, calibrate it regularly.

FAQs

Q. How to Load a Grease Gun?

A grease gun can be loaded by more than one method based on its design and construction, but in general, almost every grease gun can be loaded with one of the two common methods.

The first one uses a reservoir, which is also known as a barrel, while the second method uses the cartridge to reload the grease gun. For the reservoir grease gun, separate the grease gun’s head, locate the barrel’s end into the grease, and then attach the barrel with the grease gun’s head after filling it up with grease. As far as the cartridge is concerned, take out the empty cartridge and load the intact one and you are ready for another round. This loading method is less messy.

Q. What is the best lubricant to use with the grease gun?

If you are going to use a lubricant of low quality, it may create a build-up problem in the nozzle area, so to avoid that from happening, the lubricant should be of the best quality. That quality lubricant should also match with the dedicated grease guns as well. If you select a good quality lubricant, you won’t have any problems like leakage because it has sealing properties, and it also protects the grits from corrosion.

Q. What are the signs of under and over-greasing?

Lubrication is extremely important for the maintenance of any moving machinery, be that as it may, Over greasing or under greasing can create some issues as well

So how do you know if you have lubricated the machine with too much grease? If that’s the case, then it will cause the asset to jam and will damage the seals and motor winding too. So if you notice these issues, there is a good chance that too much lubricant must have caused this problem.

If you haven’t supplied plenty of grease to the lubricant, then it is going to fail, it isn’t that hard to detect. Other signs of under greasing are odd sounds and excessive heat from the machinery. There may also be friction wear or bearing starvation.

Q. What is a grease gun coupler?

To lubricate the moving parts, a grease gun needs to be attached to the mechanical component, Which is possible with the help of a grease gun coupler. A coupler is a pipe that usually comes as a grease gun accessory and is of a quick-release nature.

Q. How should a grease gun be stored?

The cartridge full of grease should always be kept vertically. If any cartridge tube is left in the grease gun, then clean it properly by depressurizing. Remove the contaminants if there are any with some soft fabric. Keep it in a flat position at a cool and dry place and avoid leaking of oil.
