Use grease gun nozzle caps to help keep contamination out.
Wipe fitting before use to clear debris. Use clean shop rag or lint free cloth to clear debris.
Inspect grease fitting. Replace defective or damaged fittings.
Where possible, standardize on fitting type.
Conspicuously mark the grease fitting with the type of grease being used. Avoid changes where possible.
Learn proper grease gun operation and know the delivery volume per shot. Have grease guns calibrated occasionally to insure proper volume delivery.
Some grease guns develop pressure up to 15,000 psi. Exercise caution to avoid over packing and/or seal damage.
Keep guns clean, avoiding laying them on dirty surfaces. Repack on a clean bench using a gun loader fitting.
Keep grease guns covered when not in use.
Exercise caution to ensure safety. Make changes such as piping out fitting to avoid danger.
When repacking grease guns from a pressure line, wipe down the fitting and the pressure line to prevent contamination. When repacking with tubes, move to an environmentally controlled area, such as a control room, to replace the tube.
