Grease guns should be dedicated to particular greases and they should not be interchanged. Applying the wrong grease can cause an incompatibility problem that can quickly cause bearing failure. Lubrication tasks should be clearly outlined to ensure that the correct type and amount of grease is used in each specific greasing point. Best practices assist in this area by applying colored labels, adhesive dots, or paint markers to all grease points. These marking systems are duplicated on the grease guns, allowing for improved identification of task requirements.
