A Guide on How to Safely Operate a Grease Gun

When it comes to machinery, they all must be lubricated in order to ensure smooth operation and to prolong equipment life. One of the most common ways to achieve proper lubrication is using a grease gun.

There are four main types of grease gun for sale on the market: manual, air-powered, battery-operated and AC electric. Although each type comes with its own specifications, there are general rules that apply to all them, including training, proper use, personal safety and work area safety.

Types of Grease Guns

Manual Grease Guns

Pistol-grip and lever-action are the two models of manual grease guns available. They are the most popular as well as the most economical type of grease gun for sale.

Air-powered Grease Guns

Compressed air is used by these guns to add pressure to an air piston, which makes the grease piston to force lubricant out of the coupler into a grease fitting, leading a steady flow of lubricant to be dispensed.

Battery-Operated Grease Guns

These guns are ideal for speeding up routine lubrication tasks. These guns can also help minimize operator fatigue.

AC Electric Grease Guns

AC electric grease guns provide a consistent flow of grease and are usually used as an alternative to air-powered tools.


Proper lubrication requires specific training, which includes the actual physical activity of applying the lubricant to the effects of misapplication such as spills and damage to the equipment. It is very important that the operator receives proper training regarding different pieces of equipment that need lubrication as well as the type of grease that will be used.

Proper Tool Use

Regardless the type of grease gun you choose, the pressure developed by the gun is something that needs to be considered. High pressure can be developed in different ways and a common issue that happens when high pressure is created is frozen fitting. When a component is not lubricated for a certain time, grease solidification can occur in the line. High-pressure injection injuries can be caused by accidental injection of grease through the skin and into the underlying tissue. While this kind of injury tends to be small and essentially painless, medical attention is required as the lubricant will need to be removed and treated in order to prevent infection.

Personal Safety

It is of vital importance that you wear personal protective gear such as gloves, safety glasses, and non-skid shoes to help prevent injury. Avoid using any kind of jewelry or loose or torn clothing that could become caught in moving parts.
