Using Spray Nozzle
(See fig 13-14)
- To connect or disconnect spray tip, pull back on the quick-connect collar. Insert or remove spray tip then release collar.
- When spray tip is connected, pull on the spray tip to make sure it is secured.
- For general cleaning use the 40° spray tip. This option is for cement walkways.
- For stripping, spot cleaning, blasting, and hard to reach areas use the 25° spray tip. This option is for removing paint, rust, mildew, marine growth off boats, or grease stains. This option can be used for reaching second story surfaces, or for the removal of paint, rust, oil stains, tar, gum, and other stubborn substances. Use extreme caution when using this nozzle.
- For applying pressure washer safe detergent, use the black soap nozzle.
- The angle of the nozzles shown indicates the spray “fan shape” projected from the nozzle when the trigger of the spray gun is pulled and high pressure water is passing through the nozzle. The pressure and flow will not change significantly due to the various fan patterns (Nozzles).
Applying Detergent
- Rinse surface with cool water before applying cleaner.
- Prepare detergent as required by job. For best results follow detergent directions as supplied from manufacturer.
- Remove cap from detergent container and fill.
- Spray detergent on surface. For best results use long, even, and overlapping strokes. Allow detergent to set for about
3 minutes before rinsing, but do not allow detergent to dry on surface or it may cause streaking or cause damage to the surface. Use good judgment. - To clean equipment after use, flush water through the spray nozzle for 1-2 minutes then shut off engine. Soak nozzle in a bucket of clean water to remove detergent.
