SATA ST97203 Plastic Handle Grease Gun 400cc

Key features include a durable corrosion‑resistant barrel, a lightweight plastic handle for comfortable grip, high-pressure output for effective lubrication, an air bleeder valve to eliminate air pockets, an easy loading mechanism for quick cartridge or bulk-fill use, and a safety locking feature to prevent accidental discharge.

The ST97203 is compatible with standard grease cartridges and bulk-fill options, providing flexibility for automotive, agricultural, and industrial lubrication tasks. It supports a range of greases commonly used in these applications and is designed for smooth, consistent flow.

For cartridges: remove the cap, insert a standard grease cartridge, and pull back the follower rod to place the cartridge in and seal it. For bulk fill: open the loading area, pour in the grease up to the capacity, and reseal. Then prime the gun by operating the piston until grease starts to flow smoothly.

The air bleeder valve eliminates air pockets in the chamber, ensuring continuous, consistent grease flow. This reduces pump cavitation and clogs, delivering reliable lubrication under high-pressure operation.

The safety lock prevents accidental grease discharge during storage and transport. To use it, engage the lock when not actively pumping, and disengage it before applying pressure to dispense grease.

It's well suited for automotive, agricultural, and industrial lubrication tasks—ideal for bearings, hinges, linkages, and other moving parts that require controlled, high-pressure grease delivery in clean, efficient bursts.

Keep the piston mechanism clean and free of debris, prime the gun before use, ensure the nozzle and seals are in good condition, and use the appropriate grease type. Regularly inspect the barrel and seals, and clean after each use to extend life.

High-pressure output helps push grease through tight fittings and narrow passages, improving penetration and coverage on tough-to-lubricate components. It contributes to more efficient maintenance and longer component life.

Wipe down after use, store in a clean, dry place, periodically inspect seals and the air bleeder valve, and lightly lubricate moving parts as needed. Clean any residual grease from the barrel and piston to prevent buildup and clogs.
