CICZ SL-LD-004 Cordless Grease Gun, 12,000 PSI, Variable Speed, 39-Inch Hose

For mechanics and equipment owners handling recurring lubrication, the CICZ SL-LD-004 brings powered grease delivery to routine service work. Its variable-speed trigger lets you control the flow at the fitting. Compatibility with Milwaukee 18V batteries makes it a practical fit for users who already have a compatible battery.

At a glance

This cordless grease gun delivers up to 12,000 PSI and has a 14 oz/400 cc capacity. The variable-speed trigger helps you apply grease with controlled finger pressure, while the 39-inch flexible hose reaches grease fittings on trucks, tractors, bearings, and heavy equipment. Four couplers provide options for connecting to fittings, and the quick-lock coupler is designed to stay attached while you work.

The tool uses grease in NLGI #0, #1, or #2 grades. A shoulder strap and carrying case support transport between jobs, while the built-in hose organizer helps keep the hose arranged for storage. Buyers also highlight perceived build quality and value, two considerations when choosing a tool for repeated mechanical maintenance.

Maintenance

For routine lubrication, load the grease cartridge, connect the coupler to the fitting, and use the trigger to manage the grease flow. The powered operation takes the repeated pumping motion out of the task, which can be useful when servicing several fittings or machines in one session. The long flexible hose gives you room to position the tool as you work around equipment.

The gun is compatible with Milwaukee 18V M/18 batteries. A battery and charger are not included, the product recommends a 4.0Ah or higher-capacity battery to maintain maximum pressure and support longer operation. This setup is especially convenient for a workshop or service kit that already uses compatible batteries. The cartridge format and stated NLGI grease range help you match the lubricant to the maintenance job.

Compared with a manual grease gun, this powered design is suited to users who want motor-driven grease delivery for repetitive work. The variable-speed trigger adds control at each fitting, while the quick-lock connection helps keep the coupler in place as you apply lubricant.

Best use cases

Use the CICZ grease gun for lubrication jobs on tractors, trucks, and heavy equipment, including greasing bearings and fittings during scheduled maintenance. It is also suited to workshop work where multiple machines need attention: the carrying case makes the tool easier to move between work areas, and the hose organizer keeps the flexible hose contained between tasks.

For example, when servicing a tractor, the operator can connect the coupler to each grease fitting and use the trigger to dispense grease as needed. The shoulder strap offers another way to carry the tool during a service routine, while the 39-inch hose helps position the gun at fittings around the equipment. Its 14 oz/400 cc capacity provides a cartridge-sized format for these mechanical applications.

Should you buy it?

A solid pick if you need a cordless grease gun for recurring equipment lubrication and already use compatible Milwaukee 18V batteries. Its 12,000 PSI maximum pressure, variable-speed trigger, flexible hose, and four couplers bring useful control and connection options to work on trucks, tractors, and heavy machinery. Choose it for powered grease application across routine maintenance tasks, with the convenience of a carrying case and organized hose storage.
