Setup

Follow these steps to prepare your HECHT HEC-3635 pump for operation:

1. Unpacking and Inspection: Carefully remove the pump from its packaging. Inspect for any signs of damage during transit. Ensure all components are present.
2. Positioning: Place the pump on a stable, level surface. Ensure there is sufficient space around the pump for ventilation and operation.
3. Connecting Hoses:
   • Attach the suction hose to the inlet port and the discharge hose to the outlet port. Secure all connections with appropriate clamps to prevent leaks.
   • Ensure the suction hose is equipped with the included suction basket to prevent debris from entering the pump.
   

   The included suction basket protects the pump from foreign objects, ensuring clean operation.

4. Adding Fuel and Engine Oil:
   • Fill the fuel tank with unleaded gasoline. Do not overfill.
   • Check the engine oil level and add recommended engine oil if necessary. Refer to the engine manual for specific oil type and capacity.

Operating

Once the pump is set up, follow these steps for operation:

1. Starting the Engine:
   • Ensure the fuel valve is open and the engine switch is in the 'ON' position.
   • If the engine is cold, apply choke as needed.
   • Pull the starter cord firmly until the engine starts. Once started, gradually release the choke.
2. Priming the Pump: Before starting the engine, ensure the pump casing is filled with water through the priming port. This is crucial for self-priming pumps to initiate flow.
3. Monitoring Operation: Observe the pump during operation. Ensure water is flowing smoothly and there are no unusual noises or vibrations. The pump can achieve a maximum lift height of 32 meters and a flow rate of up to 38,000 liters per hour.


The water pump can easily overcome a delivery head of up to 32 meters.



With its powerful engine, the pump can transport up to 38,000 liters per hour.

Maintenance

Regular maintenance ensures the longevity and optimal performance of your pump:

• Cleaning: After each use, clean the pump exterior and clear any debris from the suction basket and impeller area.
• Engine Oil: Check the engine oil level before each use. Change the engine oil according to the schedule in the engine manual, typically after the first 20 hours and then every 50-100 hours of operation.
• Spark Plug: Inspect the spark plug periodically. Clean or replace it if it is fouled or worn.
• Air Filter: Clean the air filter regularly, especially when operating in dusty conditions. A clogged air filter can reduce engine performance.
• Hoses and Connections: Inspect hoses for cracks or wear and ensure all connections remain tight.
