- Connect the Hose and Coupler:
- Attach the high-pressure rubber hose to the pump outlet. Ensure a tight connection to prevent leaks.
- Connect the regular grease coupler to the other end of the hose.
- Prime the Pump (Initial Use):
- Before connecting to a grease fitting, operate the pump a few times to ensure grease flows through the hose and coupler, expelling any air.
4. Operating Instructions
The Groz FOP/10A grease pump can be operated using the foot pedal or manually for specific applications.
4.1 Foot Operation
- Position the Pump: Place the pump on a stable, flat surface near the lubrication point.
- Connect to Fitting: Securely attach the grease coupler to the grease fitting (Zerk fitting) on the equipment to be lubricated.
- Operate the Foot Pedal: Step on the foot pedal repeatedly to pump grease. Each full stroke delivers approximately 2 grams of grease.

- Monitor Grease Flow: Continue pumping until fresh grease is visible or until the fitting is adequately lubricated. Avoid over-greasing.
- Disconnect: Release the coupler from the grease fitting.
4.2 Hand Operation (for low-height machines)
For situations where foot operation is impractical due to low clearance, the pump can be operated manually.
- Position the Pump: Place the pump in an accessible location.
- Connect to Fitting: Securely attach the grease coupler to the grease fitting.
- Operate Manually: Use your hand to press down on the foot pedal mechanism. This will pump grease in the same manner as foot operation.
- Monitor and Disconnect: Lubricate as needed and then disconnect the coupler.

5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your Groz FOP/10A grease pump.
- Clean After Use: Wipe down the pump and hose after each use to remove excess grease and dirt. This prevents contamination and keeps the unit in good condition.
- Check Hose and Coupler: Regularly inspect the high-pressure hose for cracks, kinks, or damage. Ensure the coupler is clean and functions correctly. Replace worn or damaged parts immediately.
- Grease Quality: Always use clean, appropriate grade grease (NLGI 1 or 2). Contaminated grease can damage the pump mechanism and the equipment being lubricated.
- Storage: Store the grease pump in a clean, dry environment when not in use.
