A grease gun can be a handy tool for the home mechanic because car parts often need to be greased to reduce friction and increase the life of the part. A grease gun can inject grease into areas that are difficult to reach. Using a grease gun can be easy once you have taken it apart and loaded it. By doing this, you immediately see how the gun works and you are ready to use it with no further directions.

Using a Grease Gun

Auto technician Jason Shackelford advises putting on rubber gloves before using a grease gun. Remove the head of the gun and load a new cartridge of grease into the barrel. Depress the rod handle to dispense grease. Make sure the cap is tight, and wipe the nozzle so grease doesn't clog the opening.
