We can further categorize the grease guns into three types with aspect to the ways of their working. Understand the types of models before moving forward.

Manual Grease Gun:

The manual grease gun is the most common and simple. It uses the traditional hand-pumping method to deliver the grease. In the market, you will find lever and pistol grip grease guns supporting the manual pumping method. This type of grease gun can deliver about 1 gram of grease per pump.

Electric Grease Gun:

Electric grease gun uses a battery or any other power source to operate. Most of these grease guns are cordless. Although the delivery rate varies among different guns but normally electric grease guns have a delivery pressure of 10,000 PSI which makes them way more efficient than the traditional grease guns.

Pneumatic Grease Gun:

A pneumatic grease gun is an air-powered grease gun that uses the air (air is already compressed in the gun through its hose) to get the grease out of it. This type of grease gun is better in a way that it requires neither any hand-pumping work nor the electric source. These types of grease guns have more delivery rate than manual grease guns and less than electric ones.

  1. First of all, you should make sure that your grease gun is loaded with lubricant. If not, load the grease gun first.
  2. Check the output (amount of oil it delivers per pump) of the grease gun. Usually, you will find it printed on the manual which comes with the original purchase.
  3. Determine the location you are going to lubricate.
  4. Lubricate the machinery. Make sure that you have delivered the exact amount of grease which is required. Avoid over lubrication.

  • Unscrew the cap from the grease gun. You will need to push the cap in the left direction with a little force.
  • Remove the old cartridge present in it. Never mix the old cartridge with a bad one as it will affect the quality of it.
  • Now open the new cartridge and insert the grease into the barrel of the grease gun.
  • After filling it completely, screw the grease gun. You will need to reverse the first step.
  • Now test the grease to check whether it is working fine or not.
  • The final step is to store the grease gun in a suitable place.

  2. Do not mix the old grease with the new one or the grease of two different types. Type is usually mentioned on the cartridge pack.
  3. Make sure that you are going to use the correct type of grease to lubricate your machine. A type of grease which is beneficial for one machine may have a negative impact on other machinery.
  4. Tight the nipples, couplers, and threads to prevent leakage. Also, avoid over-tightening.
  5. Always carry tissue papers with you. Clean the grease gun and machinery part with it.
  6. Carry an extra cartridge with you so that you could refill the grease gun by pouring it.
