2. Safety Instructions

Always observe the following safety precautions to prevent injury or damage to the unit:

• Ensure the power supply matches the specifications of the unit.
• Never direct the high-pressure jet at people, animals, or electrical equipment.
• Wear appropriate personal protective equipment (PPE), including eye protection and sturdy footwear.
• Do not operate the unit if the power cord or other critical parts are damaged.
• Always disconnect the power supply before performing any maintenance or cleaning.
• Ensure adequate water supply to prevent damage to the pump. Water shortage is a common cause of high-pressure cleaner failure.
• Use a water supply hose of at least 3/4 inch diameter. A 1/2 inch hose may suffice if not excessively long.

3. Setup and Assembly

Follow these steps to set up your high-pressure cleaner:

1. Unpacking: Carefully remove all components from the packaging. Verify that all listed accessories are present, including the 20m steel-braided high-pressure hose, M 2000 safety shut-off gun, dirt killer lance, flat jet lance, and 7.5m connection cable.
2. Handle Assembly: Attach the ergonomically designed handle. Note that it can be removed for transport.
3. Hose Reel: The unit comes with an integrated hose reel and foldable crank. Ensure the high-pressure hose is properly connected to the reel and the unit.
4. Water Supply: Connect the water supply hose to the unit's inlet. The unit features a 10-liter water tank to help prevent water shortage, but a consistent external supply is crucial.
5. Lances and Gun: Connect the desired lance (dirt killer or flat jet) to the M 2000 safety shut-off gun using the D12 quick-change plug system.
6. Detergent Suction: If using detergent, connect the detergent suction system. This system allows detergent application without pressure loss.
7. Power Connection: Plug the 7.5m connection cable into a suitable power outlet.
8. Parking Brake: Engage the parking brake on the robust chassis to ensure high stability during operation.

4. Operating Instructions

To operate your Kränzle Quadro 799 TST:

1. Turn on Water Supply: Fully open the water tap to ensure a steady flow to the high-pressure cleaner.
2. Power On: Switch on the main power switch of the unit. The slow-running motor will start.
3. Purge Air: Before applying pressure, squeeze the trigger on the safety shut-off gun until a steady stream of water emerges, indicating all air has been purged from the system.
4. Adjust Pressure: The working pressure can be steplessly regulated between 30 and 180 bar. Adjust the pressure according to the cleaning task. Monitor the pressure gauge if available.
5. Apply Detergent (Optional): If using detergent, activate the detergent suction system. Ensure the correct dilution ratio for your cleaning agent.
6. Cleaning: Begin cleaning, maintaining a safe distance from the surface. The dirt killer lance is ideal for stubborn dirt, while the flat jet lance is suitable for general cleaning.
7. Safety Shut-off: The M 2000 safety shut-off gun will stop the water flow when the trigger is released.
8. Shut Down: After use, turn off the main power switch, then turn off the water supply. Squeeze the trigger on the gun to release any remaining pressure in the system before disconnecting hoses.

5. Maintenance

Regular maintenance ensures the longevity and optimal performance of your Kränzle Quadro 799 TST:

• Pump Head: The special brass pump head is designed for a very long service life. However, regular inspection for leaks is recommended.
• O-Rings: Periodically check O-rings in high-pressure connections for wear or damage. Worn O-rings can be easily replaced with standard, inexpensive replacements. Kränzle also offers specific O-rings for extended durability.
• Nozzles: Nozzles can wear out or become clogged over time. Worn nozzles reduce pressure, while clogged ones increase it. Regularly inspect and replace nozzles (standard size 045) as needed. Various nozzle types (e.g., knife jet) are available.
• Valves: If valves stick, especially after winter storage, they can often be loosened by unscrewing them and gently manipulating them with a paperclip or nail. This procedure is typically detailed in the full instruction manual.
• Water Filter: Consider installing a pre-filter on your water supply line to prevent dirt and debris from entering the pump, which can significantly extend the life of the unit.
• Storage: Store the unit in a frost-free environment. If storing for extended periods, especially in cold conditions, ensure all water is drained from the pump and hoses.
