When you press down the holder of the gun, the grease will come out at the front surface of the gun.
  • You can test the grease gun by pumping a tiny quantity of grease through the nozzle. Make sure to clean the grease that came out while testing before reattaching the nozzle.
  • Now, it is time to shut the head that you opened previously. Force out the air by pushing down the air bleeder. You will notice a stable pressure once the air is released. Make sure to locate the gun coupler at the end of the hose to grease the correct spot you want.
  • At last, try to put grease on your machinery by pumping the lever handle properly. Is your grease gun not working smoothly even after following all the steps? Then you should check whether you have skipped any step.
