Grease Gun Best Practices

  • Calculate the proper amount of grease needed for the relubrication of bearings based upon the calibrated delivery volume of the selected grease gun.
  • Use a vent plug on the relief port of the bearing to help flush old grease and reduce the risk of too much pressure on the bearing.
  • Use extreme caution when loading grease into the grease gun to ensure that contaminants are not introduced. If using a cartridge, be careful when removing the metal lid so that no metal slivers are introduced into the grease.
  • Make sure the grease gun is clearly marked to identify the grease with which it should be charged. Do not use any type of grease other than that which is identified.
  • Always make sure the dispensing nozzle of the grease gun is clean before using. Pump a small amount of grease out of the dispensing nozzle and then wipe the nozzle off with a clean rag or lint-free cloth before attaching it to the grease fitting.
  • Clean the grease fitting of all dirt before attaching the grease gun. Inspect and replace damaged fittings. It is helpful to use grease-fitting caps to keep them clean, but still wipe fittings clean before applying grease.
  • Ensure that the proper grease is used at every grease point. Applying the wrong grease can cause an incompatibility problem, which can quickly cause bearing failure. Lubrication points should be clearly identified as to which grease is to be used. This can be done with colored labels, adhesive dots or paint markers.
  • Grease guns should be stored unpressurized in a clean, cool and dry area and in a horizontal position to help keep the oil from bleeding out of the grease. Grease gun clamps make storage easy and organized. Also, cover the coupler to keep it free from dirt and contaminants.
  • Calibrate grease guns regularly to ensure the proper delivery volume.

9 Tips for Caring for Your Grease Gun

(These tips are from

A grease gun can be a highly useful and efficient addition to your tool kit. Maintaining and caring for it will allow the grease gun to last many years longer than a grease gun that is not properly maintained. Here are some tips to protect your grease gun and let you get the best from it.

Tip 1 – Cleaning

Keep your grease gun thoroughly clean before and after each use. Use a clean dry cloth to wipe the grease gun because any excess grease can make the gun slip from your hands. Cover it with a clean cloth when you are not using it. This will prevent any dust or debris from getting on it.

Tip 2 - Storing

Grease guns are not heat resistant, so keep it in a dry, cool place. Keep it horizontal and when you go to use it always make sure that all moving parts are aligned and complete. Never keep your grease gun pressurized when you are storing it. Depressurize it before putting it away.

Tip 3 – Moving Parts

Check the moving parts regularly and have a thorough knowledge of your grease gun. This will help you diagnose any issues that come up with it. Inspect the grease barrel and the trigger to make sure that they are both clean and functional.

Tip 4 – Grease Flow

Before you use the grease gun test the nozzle hole for clear flow. You can squirt a little grease onto a clean rag just to make sure it is flowing correctly.

Tip 5 – Calibration

The grease gun should be recalibrated every so often to make sure it registers how much grease can dispense for each pump (if there are multiple pumps).

Tip 6 – Type of Grease

Different grease guns require different types of grease. Mark your gun clearly to indicate which type of grease it should be filled with. Do not use any other sort because this will interfere with the calibration and internal workings of the grease gun and can damage it.

Tip 7 – Maintenance

Always maintain your grease gun according to the recommended instructions that come with the packaging. The manufacturer will give helpful hints and tips about the quality care of your grease gun. Failing to comply with these directions can cause early breakage or contamination.

Tip 8 – Hand Powered

Hand powered grease guns are worked by back pressure, like a trigger of a water gun. The vacuum created inside as you press the trigger will create a back force that dispenses the grease from the nozzle. Hand powered guns still need care and maintenance, so keep it clean and contaminant free. Store it in a cold place and cover it for protection.

Tip 9 – Piston Pumps

The piston pumps in some grease guns need care to maintain their pressure. Treat all your grease guns as directed. The same applies with air powered grease guns. The force of air needs to be channeled correctly and properly maintained.
