A grease gun is a lubrication tool used to force grease into a bearing or fitting by means of a plunger. It is a common tool used in workshops, garages, and on farms to lubricate machinery.

There are two main types of grease guns: manual and pneumatic.

• Manual grease guns are operated by hand, using a lever or pistol grip to force the grease out of the cartridge. They are a good option for occasional use or for lubricating a small number of fittings.
• Pneumatic grease guns are powered by compressed air. They are a good option for high-volume use or for lubricating a large number of fittings. They can be faster and easier to use than manual grease guns, but they require an air compressor to operate.

Here are some of the common parts of a grease gun:

• Barrel: The barrel is the tube that holds the grease cartridge.
• Plunger: The plunger is a rod that is used to force the grease out of the cartridge.
• Delivery hose: The delivery hose is a flexible hose that connects the grease gun to the grease fitting.
• Grease fitting: The grease fitting is a valve that allows the grease to enter the bearing.

When using a grease gun, it is important to follow these safety tips:

• Wear safety glasses to protect your eyes from grease sp splatter.
• Be careful not to over-grease a bearing. Over-greasing can damage the bearing seal and allow contaminants to enter the bearing.
• Do not use a grease gun on a bearing that is not designed for grease lubrication. Some bearings are lubricated with oil instead of grease.
