Pneumatic grease gun ETCS (SS) May.
Figure (1) from reference (a) shows the correct configuration for the grease gun. It is important to rig it correctly to ensure the safety of the operator and to prevent the grease lines from rupturing due to over pressurization. You can find guidance on setting up your pneumatic grease gun based on gun type and supply air pressure on page 2-7 of reference (b). Each component has a role in preventing injury or equipment damage.
OPNAVINST 5100.19E requires the labeling of all hand guns and oil cans to show the contents. Labeling helps control hazmat and prevent misuse of the wrong compound.
