2. Attaching the Hose/Extension:
   • Screw the flexible hose or metal extension firmly onto the outlet port of the grease gun head.
   • Attach the grease nipple to the end of the hose or extension if required for your application.
3. Priming the Grease Gun:
   • Point the nozzle into a waste container.
   • Pump the pistol grip handle several times until grease begins to flow smoothly from the nozzle. This removes any air pockets.

5. Operating Instructions

Once the grease gun is set up and primed, follow these steps for effective lubrication.

1. Prepare the Application Point: Clean the grease fitting (zerk) on the component to be lubricated to prevent dirt from entering the bearing or joint.
2. Attach to Grease Fitting: Press the grease gun nozzle firmly onto the grease fitting until it snaps into place. Ensure a secure connection to prevent grease leakage.
3. Apply Grease: Squeeze the pistol grip handle to dispense grease. Apply grease slowly and steadily. Observe the component for signs of lubrication, such as grease emerging from seals or a change in resistance. Avoid over-greasing, which can damage seals.
4. Remove from Fitting: Once sufficient grease has been applied, twist the nozzle slightly while pulling it away from the fitting to release it.

6. Maintenance

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

• Cleaning: After each use, wipe down the exterior of the grease gun to remove any excess grease or dirt. Keep the nozzle and fittings clean.
• Check for Leaks: Periodically inspect the grease gun for any signs of leakage, especially around connections and the piston. The leak-proof piston design minimizes leakage, but seals can wear over time.
• Storage: Store the grease gun in a clean, dry environment. If storing for an extended period, ensure it is clean and free of residual grease.
• Cartridge Replacement: When a grease cartridge is empty, replace it following the steps in the Setup section.
