Common questions
What is the best grease gun for professional mechanics?
The Lincoln Lubrication 1162 is widely regarded as the best manual grease gun for professionals due to its high pressure and durability. For battery powered convenience, the LubriMatic 12V is a top pick.
How much pressure do I need in a grease gun?
For most automotive and equipment greasing, 5,000 to 6,000 psi is sufficient. However, for stubborn fittings or heavy machinery, higher pressure like 10,000 psi can be beneficial.
Are battery powered grease guns as good as pneumatic?
Battery powered grease guns offer convenience and mobility, but they may have lower pressure and limited battery life. Pneumatic guns provide consistent pressure and faster operation but require an air source.
How often should I grease my equipment?
It depends on the equipment and usage. Many manufacturers recommend greasing every 50 hours of operation or as specified in the manual. Professional mechanics often grease daily for critical components.
Can I use any grease with a professional grease gun?
Most grease guns are compatible with standard grease cartridges (14.5 oz) or bulk grease. Always follow the manufacturer’s recommendations and use the correct consistency of grease for your application.
How do I prime a manual grease gun?
To prime a manual grease gun, you typically pull back the plunger rod, insert a grease cartridge, and then release the rod. You may need to pump a few times to expel air and get grease flowing.
What is the difference between a pistol grip and lever style grease gun?
Pistol grip guns are operated with one hand and are easier to use in confined spaces. Lever style guns require two hands but can generate higher pressure and are often used for heavy duty applications.
How do I maintain my grease gun?
Keep the gun clean and free of debris. Check the coupler for wear and replace if it does not seal properly. Periodically lubricate moving parts and store the gun in a dry place to prevent rust.
