How to use a manual grease gun

The person using the grease gun use is converted to volume with the number of pumps, often by feel. Just as not all greases are created equal, the same can be said of grease cannons. It goes beyond just the model and manufacturer. So it is good to know the volume per pump for your grease gun. You will find the yield per stroke of a hand operated grease gun when you go to our article page under technical specifications

When grease gun is for you If the volume is not known, the best way to calibrate a grease gun is to slowly pump 10 strokes of grease onto a scale and then divide the total volume by 10. This gives the average volume per pump of the grease gun.

In theory, it is best if by grease gun use a single type of grease. In practice it is often different. The danger here is that there is a high chance of cross-contamination. That is why you will find grease guns from Pressol in different colors in our range. Do you use different types of grease?

We have several hand-operated grease guns in our range. Choose a handheld grease gun that best suits your application. In addition to different colored grease guns, we also have hand-operated grease guns with transparent cartridge holders in our range. This way, you can visually check that the correct type of grease is in the gun before applying lubricant to your equipment.


Use a battery grease gun

If as a maintenance engineer you are responsible for greasing a large number of greasing points, the battery grease gun offers a solution. Easy to handle, this grease gun is ideal for speeding up routine greasing tasks. Using this type of grease gun ensure that you can carry out your work efficiently. In addition, the use of hand-operated grease guns can be experienced as heavy in the long run and lead to greaseigue.

These grease guns are also equipped with an overpressure protection. This way you can be sure that the battery grease gun is safe to use.


How to use a grease gun correctly

Make sure you use the correct grease gun with grease on hand, it is also important that the equipment is in the correct operating condition (on or off) to perform the procedure safely. Each point that needs to be lubricated is different, as is the amount of lubrication that the point in question needs. Make sure you are aware of this and then calculate how many pumps of the grease gun you need. It is calculated by dividing the volume of the lubricant by the average volume per pump of the grease gun.

Remove the grease nipple cap (if any) and clean the grease nipple with a lint-free cloth or towel. Then inspect the grease nipple for damage or wear. If the grease nipple is damaged, replace it immediately before continuing to lubricate.

Once you have connected the grease gun, you are ready to apply the grease. Slowly pump the grease into the bearing. Each pump of a manual grease gun should last three to five seconds. Keep pumping until you have reached the maximum volume of the amount of grease or feel an abnormal back pressure.

If there is significant back pressure, the passage may be blocked by grease build-up or dirt. When you use a battery grease gun with digital display, it will flash and turn red. Do not try to force the grease into the equipment. This will cause the spray head to detach from the grease nipple or break a seal in the equipment, and you may push dirt into the bearings, causing them to break.

Please note that manual grease guns can produce higher pressures than a gasket can handle. When you lubricate an electric motor, you run the risk of gaskets or other seals failing and getting grease in the wrong places. As soon as you feel excessive back pressure, lubrication should be stopped and the point to be lubricated should be thoroughly checked before resuming lubrication.

After the part is properly lubricated, disconnect the nozzle of the grease gun from the equipment and clean the lubrication point. After lubrication, put the dust cap back on the grease nipple. Is there no fabric cover available? Then leave a small amount of grease on the grease nipple, so that no dirt or dust can get into the grease nipple. This splash of grease is removed when the part needs to be lubricated again.

The most important thing to remember when storing or using your grease guns and lubricants is to keep all your lubrication equipment clean, cool and dry. This will help maximize the life of your grease.


Replacing a grease cartridge with your grease gun

When replacing a grease cartridge, remember to follow a few steps carefully. The incorrect replacement of a grease cartridge can result in a non-functional grease gun or a grease gun which does not produce sufficient volume. Which ultimately ensures that your machines do not get the desired lubrication and that parts can break.

Before you start replacing your grease cartridge, it is very important that you make sure you have enough space to do this carefully. In addition, it is important that your workplace is clean and free of dirt. This prevents dirt from entering your equipment, which is guaranteed to lead to a blockage.


When you have taken all precautions, you can safely start replacing your grease cartridge


  • Unscrew the cartridge holder and then pull back the T-handle and place it in the lock.
  • Remove the empty pattern.
  • Remove the cover on top of the cartridge
  • Place the cartridge open side down in the cartridge holder, when you have done this, remove the seal by pulling the ring.
  • Turn the cartridge holder onto the grease gun, making sure you have about two turns left.
  • Push the T-handle back to start pumping. This ensures that no air remains in the cartridge case.
  • When grease comes out of the nozzle of the grease gun, you can further tighten the cartridge holder.

The grease gun is now ready for use.
