How to Use a Grease Gun
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.
1. **Remove the head of the gun from its barrel.** 
2. **Pull the rod handle back.** 
3. **Lock the rod handle.** 
4. **Open the new grease cartridge.** 
5. **Insert the new grease cartridge into the barrel of the gun.** 
6. **Note the pull-tag on the end of the new cartridge.** 
7. **Ensure that cartridge is pushed in enough so that the rim is in contact with the rim of the grease gun.** 
8. **Reinstall the barrel to the end cap but keep it loose.** 
9. **Release the rod handle by turning it out from the retaining groove in the end cap.** 
10. **Depress the rod handle; this will force grease into the head of the grease gun and force air out.** 
11. **Pump some grease through the nozzle and wipe it clean before attaching the nozzle to the gun.** 
12. **Tighten the cap and push down on the air bleeder to force out the rest of the air.** 
13. **Place the grease gun coupler at the end of the extension hose directly on the area to be greased.** 
14. **Pump the lever handle enough times for grease to begin flowing.** 
15. **Remove the head from the barrel as above.** 
16. **Put a large amount of grease in the head and pack firmly.** 
17. **Position the barrel of the gun over a tub of grease.** 
18. **Insert the barrel down about 2 inches (5.1 cm) into the grease.** 
19. **Push down on the barrel while pulling up on the plunger or rod handle.** 
20. **Lock the rod handle when it is fully extended.** 
21. **Move the gun barrel from side to side to cut off the extra grease after the barrel is full.** 
22. **Clean off all parts with stiff paper, paper towel or rag.** 
23. **Attach the gun barrel to the rest of the unit.** 
24. **Unlock the rod handle.** 
25. **Pump the grease gun handle to start the flow of grease.** 
26. **Place the grease gun coupler at the end of the extension hose directly on the area to be greased.**
