4. Setup and Installation

Proper setup is crucial for the optimal performance and longevity of your manual lubricating oil pump. Follow these steps for installation:

1. Choose Mounting Location: Select a stable and accessible location on or near the machinery that requires lubrication. Ensure the pump is positioned vertically as per its design.
2. Secure the Pump: Use appropriate fasteners (not included) to securely mount the pump to the chosen surface. Ensure it is firmly attached to prevent movement during operation.
3. Connect Outlet Hoses: Connect the lubrication hoses (not included) to the two discharge ports (left and right) of the pump. Ensure connections are tight to prevent leaks.
4. Route Hoses: Route the hoses to the lubrication points on your machinery. Ensure hoses are not kinked or obstructed.
5. Fill with Lubricant: Unscrew the top cap of the pump reservoir. Carefully pour the appropriate lubricating oil (viscosity N20-N1000) into the reservoir. Do not overfill. Replace the cap securely.
6. Initial Priming (Optional): Before first use, you may need to operate the handle a few times to prime the pump and ensure oil flows through the system.

5. Operating Instructions

The manual lubricating oil pump is designed for straightforward operation. Follow these steps to lubricate your machinery:

1. Check Oil Level: Before operation, visually inspect the oil level through the transparent sight glass on the side of the pump. Refill if necessary (refer to Section 4).
2. Operate the Handle: Grasp the pump handle firmly.
3. Push Down: Push the handle down to its full extent. This action expels oil from the cylinder through the discharge ports to the lubrication points.
4. Release: Release the handle. The spring mechanism will pull the plunger back, drawing more oil into the cylinder from the reservoir.
5. Repeat: Repeat steps 3 and 4 as many times as required to deliver the desired amount of lubricant to your machinery. The discharge capacity is approximately 8 ml per stroke.

6. Maintenance

Regular maintenance ensures the longevity and reliable performance of your lubricating oil pump.

• Oil Level Check: Routinely check the oil level in the reservoir using the sight glass. Refill promptly when low to prevent air from entering the system.
• Lubricant Quality: Always use clean, high-quality lubricating oil within the recommended viscosity range (N20-N1000). Contaminated oil can damage the pump and the machinery it lubricates.
• Cleanliness: Keep the exterior of the pump clean. Wipe away any spilled oil immediately to prevent accumulation of dirt and debris.
• Check for Leaks: Periodically inspect all connections and seals for any signs of oil leakage. Tighten connections or replace seals if leaks are detected. The pump is designed with high-quality seals to minimize leakage, but regular checks are still important.
• Filter Inspection: If your pump model includes an internal filter (as shown in some images), periodically inspect and clean or replace it to ensure proper oil flow and prevent contaminants from reaching the pump mechanism.
