Grease Gun Best Practices

"Can you give me some advice on how to use

a grease gun properly?"

When lubricating equipment with a greasegun, it is important to know precisely how

much lubricant needs to be applied per cycle

and how much lubricant the grease gun will

produce per shot. Grease guns can produce

between 1 gram and 1.5 grams per shot. This

can result in significant overlubrication per

point unless the output is known.

Grease guns are capable of producing several

thousand psi per stroke. This kind of pressure

can certainly blow out bearing seals and shields. If a careless approach is taken when using

the grease gun, then it is highly likely that the equipment will be overpressurized and

overlubricated. When this occurs, particularly with a bearing, then the li kelihood that the

bearing can see its rated lifecycle is greatly reduced.

Whether the gun is filled with oil or grease, the practitioner should be precise with the use of

the gun, beginning with an analysis of the bearing dimensions and calculation of the

required amount of grease per cycle, followed by an analysis of the amount of output per

cycle of the gun.

When working the grease gun lever arm, never hold the nozzle onto the grease fitting. Also,

when cycling the lever arm, be conscious of the risk of overpressurization and do not force

the lever arm i f there is strong back pressure.

Use the following tips to maintain your grease guns and fittings.

Wipe the fitting before use to clear debris. Use a clean shop rag or lint-free cloth to

clear debris.

Inspect the 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 the proper grease gun operation and know the delivery volume per shot. Have

grease guns calibrated occasionally to ensure proper volume delivery.

Some grease guns develop pressure up to 15,000 psi. Exercise caution to avoid

overpacking 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 the 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.
