F&A

  1. What is a Grease Gun?
    A grease gun is a tool used for applying lubricant (grease) to machinery, vehicles, and equipment that requires regular lubrication. Our range of J-KU grease guns includes both manual and powered models, designed for ease of use, efficiency, and durability. We offer both straight-handle and gun-style 2-in-1 lithium grease guns.

  2. How do J-KU Grease Guns Work?
    Our grease guns are designed with advanced technology to ensure precise and efficient grease application. The lithium battery-powered models (SL-LD-B003 and SL-LD-B004) are equipped with a high-performance motor, ensuring smooth operation. Manual models (KL8005) offer great control and durability for a range of applications.

Usage and Compatibility:

  1. How do I set up the J-KU Grease Gun?
    For battery-powered models:

    • Fully charge the grease gun using the provided charger.

    • Attach the appropriate hose or nozzle (e.g., 100cm explosion-proof hose, or 18cm straight nozzle).

    • Turn on the gun and begin applying grease to your equipment.

    For manual models:

    • Attach the hose or nozzle.

    • Pump the grease gun manually to apply grease.

  2. Are the J-KU Grease Guns compatible with all grease types?
