3. Spezifikationen

This pump is designed to deliver 4 GPM at 4000 PSI and is compatible with 13hp-15hp gas engines featuring a 1-inch shaft. It includes an unloader and inlet for immediate integration.

4. Einrichtung und Installation

1. Motorvorbereitung: Ensure your gas engine is between 13hp and 15hp and has a 1-inch diameter shaft. The engine should be turned off and cooled before installation.
2. Montage der Pumpe: Align the pump's mounting flange with the engine's mounting points. Secure the pump firmly to the engine using appropriate bolts and washers. Ensure a snug fit to prevent vibration and misalignment.
3. Wellenverbindung: Carefully slide the pump onto the engine shaft. Ensure the keyway aligns correctly with the key on the engine shaft. Secure the pump to the shaft according to your engine manufacturer's instructions, typically with a set screw or bolt.
4. Wassereinlassanschluss: Connect a garden hose or other suitable water supply line to the pump's inlet port. Ensure the connection is tight to prevent air leaks, which can cause cavitation and damage the pump. A minimum of 4 GPM water supply is recommended.
5. High-Pressure Outlet Connection: Connect your high-pressure hose to the pump's outlet port. Ensure this connection is also secure.
6. Entlastungsventil: The pump comes with an integrated unloader valve. This valve regulates pressure and diverts water when the trigger gun is closed. Ensure it is properly connected and adjusted for your desired operating pressure.
7. Ölstandskontrolle: Before first use, check the pump's oil level. Refer to the maintenance section for oil specifications and proper filling procedures.

5. Bedienungsanleitung

1. Wasserversorgung: Turn on the water supply completely before starting the engine. Allow water to flow through the pump and out of the high-pressure hose (without the spray gun attached) to purge any air from the system.
2. Motorstart: Start the gas engine according to its manufacturer's instructions.
3. Druckeinstellung: The unloader valve allows for pressure adjustment. Turn the black knob on the unloader valve to increase or decrease pressure. Always adjust pressure gradually.
4. Betrieb: Once the engine is running and water is flowing, attach the spray gun and desired nozzle. Squeeze the trigger to begin spraying.
5. Abschalten: To shut down, release the trigger, turn off the engine, and then turn off the water supply. Squeeze the trigger gun briefly to relieve any residual pressure in the system.

6. Wartung

Regular maintenance is crucial for the longevity and performance of your pump.

• Ölwechsel:
  • First Oil Change: Nach den ersten 50 Betriebsstunden.
  • Subsequent Oil Changes: Every 3 months or 200 hours of operation, whichever comes first.
  • Use non-detergent pump oil (e.g., SAE 30 or 15W-40, consult pump specifications for exact type). Do not overfill.
• Einlassfilter: Regularly inspect and clean the inlet filter screen to prevent debris from entering the pump.
• Düsen: Clean or replace clogged nozzles to maintain optimal pressure and flow.
• Verbindungen: Periodically check all hose connections for leaks and tighten as necessary.
• Überwinterung: In freezing temperatures, the pump must be protected. Drain all water from the pump or use a pump protector/antifreeze solution to prevent damage from freezing.
