pattern as shown below.
Follow these instructions to change spray tips:
1. Pull back collar on quick–connect and pull current spray tip
off. Store spray tips in holder provided on the handle.
2. Select desired spray tip:
• For gentle rinse, select white 40° or green 25° spray tip.
• To scour surface, select yellow 15° or red 0° spray tip.
• To apply detergent, select black spray tip.
3. Pull back on collar, insert new spray tip and release collar.
Tug on spray tip to make sure it is securely in place.
Usage Tips
• For most effective cleaning, keep spray tip from 8 to
24 inches away from cleaning surface.
• If you get spray tip too close, especially using a high
pressure spray tip, you may damage surface being cleaned.
• DO NOT get closer than 6 inches when cleaning tires.
Cleaning and Applying Detergent
To apply detergent, follow these steps:
1. Review use of spray tips.
2. Prepare detergent solution as required by job.
3. Place small filter end of detergent siphoning tube into
detergent container.
NOTE: Make sure the filter is fully submerged in detergent while
applying detergent.
4. Make sure black spray tip is installed.
