Milwaukee M18GG-0: Cartridge Loading and Maintenance Checks

Blog

Find the M18GG operator manual and check cartridge size, priming guidance, hose ratings and maintenance instructions before using the grease gun.

Successful lubrication depends on the tool setup and the equipment being serviced. Use the Milwaukee M18GG operating manual alongside the equipment manufacturer's lubrication instructions.

Before changing a cartridge or accessory

The M18GG manual specifies a 450g cartridge and directs users to remove the battery before changing accessories or loading the tool. It also calls for eye protection and accessories rated for at least 10,000 PSI (690 bar). Follow the complete instructions in the manual rather than treating this checklist as an operating procedure.

Loading and priming

The manual contains separate cartridge-loading and priming sections. If grease does not flow as expected after loading, consult its priming instructions before continuing. Use the grease type and quantity specified for the equipment you are maintaining.

Keep the maintenance information together

Keep the grease gun manual with your equipment's service schedule. Record the lubricant used and the service date so the next maintenance visit starts with the correct information. For repairs, use the manufacturer's service guidance.

Read Milwaukee's M18GG operator manual for the full loading, priming, operation and maintenance instructions.
