Setup

Loading a Grease Cartridge

1. Unscrew the barrel from the head of the grease gun.
2. Pull the plunger rod all the way back and lock it into place by rotating the handle.
3. Remove the cap from one end of a standard 400g grease cartridge and insert the open end into the barrel.
4. Remove the seal from the other end of the cartridge.
5. Screw the barrel back onto the grease gun head securely.
6. Release the plunger rod by rotating the handle and push it forward to create pressure.

Loading Bulk Grease

1. Unscrew the barrel from the head of the grease gun.
2. Pull the plunger rod all the way back and lock it into place by rotating the handle.
3. Using a spatula or similar tool, carefully fill the barrel with bulk grease, ensuring no air pockets are trapped.
4. Screw the barrel back onto the grease gun head securely.
5. Release the plunger rod by rotating the handle and push it forward to create pressure.

Priming the Grease Gun

After loading, it is essential to prime the grease gun to remove any trapped air and ensure a consistent flow of grease.

1. Attach the flexible hose or rigid pipe to the grease gun head.
2. Point the nozzle into a waste container.
3. Pump the handle repeatedly until grease begins to flow smoothly from the nozzle. If no grease flows, slightly unscrew the barrel from the head to release trapped air, then re-tighten and pump again.

Operating Instructions

Once the grease gun is loaded and primed, it is ready for use.

1. Clean the grease fitting (nipple) on the component to be lubricated.
2. Firmly press the coupler of the grease gun onto the grease fitting until it snaps into place. Ensure a secure connection to prevent grease leakage.
3. Pump the pistol handle slowly and steadily. Observe the component being lubricated for signs of grease expulsion or until the desired amount of grease has been applied.
4. To remove the coupler from the fitting, twist and pull firmly. If the coupler is stuck, slightly tilt it while pulling.

Maintenance

Regular maintenance ensures the longevity and proper function 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 coupler clean to prevent contamination of grease fittings.
• Storage: Store the grease gun in a clean, dry environment. Avoid extreme temperatures.
• Inspection: Periodically inspect the hose, coupler, and barrel for signs of wear, damage, or leaks. Replace any worn or damaged components immediately.
• Pressure Release: If storing for an extended period, it is advisable to release any remaining pressure in the gun.

Troubleshooting

Here are some common issues and their solutions:

• No Grease Flow:
  • Check if the grease cartridge is empty or if bulk grease has run out.
  • An air pocket may be trapped. Try priming the gun again as described in the Setup section.
  • The nozzle or coupler may be clogged. Clean or replace if necessary.
  • Ensure the plunger rod is fully engaged and creating pressure.
• Grease Leaking from Coupler:
  • The coupler may not be securely attached to the grease fitting. Ensure a firm connection.
  • The grease fitting itself might be worn or damaged.
  • The coupler's internal jaws or seal may be worn. Replace the coupler if needed.
• Grease Leaking from Barrel Threads:
  • Ensure the barrel is tightly screwed onto the gun head.
  • Check the O-ring seal between the barrel and the head for damage. Replace if necessary.
