2. Connect the 2m external suction hose to the designated external suction port on the sprayer unit.
3. Place the other end of the suction hose into your external liquid container (e.g., a 10-liter jerrycan).
4. Ensure the external container is placed on a stable, level surface, preferably at the same level or slightly below the sprayer unit for optimal suction.

5.1. Filling the Tank

1. Ensure the sprayer is turned off and disconnected from any power source.
2. Unscrew the cap of the 10-liter internal tank.
3. Carefully pour the desired liquid into the tank, observing the maximum fill line. Avoid overfilling.
4. Securely screw the cap back onto the tank.

5.2. Selecting Nozzles

The PowerJet 2 comes with 7 different nozzles for various applications:

• Straight Jet Nozzle: For long-range spraying, such as reaching high roofs or distant areas.
• Mist Nozzle: For fine, even coverage on delicate plants or when a broad, light application is needed.
• Facade Nozzle: Designed for cleaning or treating vertical surfaces like walls and facades.
• Weeding Nozzle: For targeted application of herbicides to specific areas.
• Other nozzles are included for specialized tasks. Refer to the nozzle guide for specific details.

5.3. Spraying Techniques

Turn on the sprayer using the power switch. The 5.5 bar pump with pressure switch ensures a powerful and consistent spray, automatically starting and stopping as needed.

5.3.1. Roof Moss Removal

Utilize the straight jet or long-range nozzle with the extended carbon lance to achieve a 10-meter reach from the ground. This allows for safe application without the need for ladders in many cases.

6. Maintenance

6.1. Cleaning After Use

Proper cleaning after each use is crucial for the longevity of your sprayer.

1. Empty any remaining liquid from the tank.
2. Fill the tank with clean water.
3. Operate the sprayer, spraying clean water through the lance and nozzle for several minutes until the tank is empty. Repeat this process 3-4 times to thoroughly flush the system.
4. Clean the exterior of the sprayer with a damp cloth.
5. Remove and clean nozzles separately to prevent clogging.

6.2. Battery Care

To maintain battery health, it is recommended to operate the sprayer at least once every 1.5 months, even if just with water, to keep the battery active.

6.3. Storage

Store the sprayer in a cool, dry place, away from direct sunlight and extreme temperatures. Ensure the tank is empty and clean before storage.

7. Troubleshooting

If you encounter issues with your PowerJet 2 sprayer, refer to the following common troubleshooting steps:

• No Spray or Weak Pressure:
  • Check if the battery is charged.
