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 deter-
gent 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.
Only use mild, environmentally friendly detergents intended for use in pressure washers.
Ask at your specialist dealer about these special products. Never use aggressive chemicals
(eg bleach), abrasive detergents or similar to avoid damage to your health, the product and
the environment.
