5. Operating Instructions
Follow these steps for effective operation of your HD101 sprayer:
- Fill the Tank: Unscrew the pump assembly by turning it counter-clockwise. Use the funnel-shaped opening to pour your desired liquid solution into the translucent tank. The measurement markings on the side of the tank will help you achieve precise mixing and refills. Do not overfill past the MAX line.
- Secure the Pump: Reinsert the pump assembly and turn it clockwise to tighten it securely.
- Pressurize the Sprayer: Pump the handle 20-35 times until you feel resistance, indicating sufficient pressure has built up inside the tank. The number of pumps may vary depending on the liquid level.
- Adjust Nozzle: Twist the adjustable nozzle to change the spray pattern from a fine mist to a powerful jet, or use the fan tip nozzle for broad coverage.
- Begin Spraying: Squeeze the trigger handle on the wand to begin spraying. Release the trigger to stop.
- Release Pressure: After each use, or before opening the tank, always depressurize the sprayer by pulling the pressure release valve to the side until all air escapes.

6. Maintenance
Proper maintenance ensures the longevity and optimal performance of your Petratools HD101 sprayer:
- Cleaning: After each use, thoroughly clean the sprayer by filling it with warm, soapy water and spraying until the tank is empty. This prevents residue buildup and clogs.
- Filter Maintenance: The sprayer features high-quality built-in filters to prevent debris from clogging the nozzle. If the nozzle becomes clogged or spray is inconsistent, disassemble the nozzle and clean the filters to restore optimal performance.
- Storage: Store the sprayer in a cool, dry place away from direct sunlight and extreme temperatures. Ensure the tank is empty and depressurized before storage.
