3. Setup

1. Unpacking: Carefully remove all components from the packaging. Inspect for any damage.
2. Wheel Assembly: Attach the universal wheels to the base of the grease barrel if not pre-assembled. Ensure they are securely fastened.
3. Handle Attachment: Secure the push-pull handle to the grease barrel.
4. Grease Filling:
   • Open the lid of the grease barrel.
   • Fill the barrel with the desired type of grease (0-3#). Do not overfill.
   • Close the lid securely, ensuring a proper seal.
5. Hose Connection: Connect the high-pressure rubber hose to the pump unit and the grease gun. Ensure all connections are tight to prevent leaks.
6. Air Supply Connection: Connect your air compressor hose to the air inlet on the pump's air regulator filter. Ensure the air supply is clean, dry, and regulated to the recommended pressure range of 6-8 bar (87-116 PSI).

4. Operation

1. Prepare the Pump: Ensure the grease barrel is filled and all connections are secure.
2. Connect Air: Connect the air supply to the pump. The air regulator will show the incoming pressure.
3. Prime the Pump (if necessary): If using for the first time or after refilling, it may be necessary to prime the pump. Point the grease gun into a waste container and briefly activate it until grease flows consistently.
4. Lubrication:
   • Attach the appropriate nipple (Japanese, American, or European type) to the grease gun, if needed.
   • Place the grease gun nozzle firmly onto the grease fitting of the component to be lubricated.
   • Press the trigger on the grease gun to dispense grease. Release the trigger to stop the flow.
   • Lubricate until the desired amount of grease has been applied or until resistance is felt.
5. After Use: Disconnect the air supply from the pump. Relieve any residual pressure in the system by briefly activating the grease gun into a waste container.

5. Maintenance

Regular maintenance ensures the longevity and optimal performance of your grease pump.

• Daily:
  • Wipe down the pump and grease gun to remove excess grease and dirt.
  • Check all hose connections for tightness and signs of wear.
• Weekly/Monthly:
  • Inspect the high-pressure hose for cracks, kinks, or damage. Replace if necessary.
  • Check the air regulator filter for accumulated moisture or debris. Drain or clean as needed.
  • Ensure the universal wheels are clean and roll freely.
• Grease Type: Avoid mixing different types of grease unless explicitly stated as compatible by the grease manufacturer. Incompatible greases can cause blockages or damage to the pump.
• Storage: Store the pump in a clean, dry environment when not in use.
