Operation (Continued)
INITIAL HIGH PRESSURE RINSE
Spray the cleaning surface with water to clear off any dirt or grime that may have
collected on the surface. Doing so allows the detergent to attack the deep down dirt
that has worked its way into the cleaning surface.
Trigger the gun 3 to 5 times to get any trapped air out of the system.
Adjusting the Spray Fan Angle
Two quick connect tips for Model CP5216 or five quick connect tips for Models CP5211
and CP5321 are included with this pressure washer. The tips have a range of spray fan
angles, ranging from 0°, narrow high impact, to a 65° wide fan spray.
Pressure can also be adjusted by moving closer or further away from the cleaning
surface and by adjusting the spray fan angle as shown.
Angle to the Cleaning Surface
When spraying water against a surface, you can generate maximum impact by striking
the surface head on. However, this type of impact can cause dirt particles to embed in
the surface and can prevent the desired cleaning action.
The optimum angle for spraying water against a cleaning surface is 45 degrees.
Spray water against a surface at a 45 degree angle to achieve the most beneficial impact
force and to efficiently remove debris.
Distance From Cleaning Surface
The distance between the spray tip and the cleaning surface is another factor that
affects the impact force of the water. The impact force of the water increases as the tip
is moved closer to the surface.
How to Avoid Damaging Surfaces
Damage to cleaning surfaces occurs because the impact force of the water exceeds
the durability of the surface. You can vary the impact force by controlling the spray
tip angle to the cleaning surface and the distance from the cleaning surface and by
changing the spray tip. NEVER use a narrow high impact stream on a surface that is
susceptible to damage. Avoid spraying windows with a narrow high impact stream.
Doing so may break the window. The most sure way to avoid damaging surfaces is to
follow these steps:
1. Before triggering the gun, make sure the quick connect tip you are using is
appropriate for the application.
2. Place the spray tip approximately 4-5 feet (1,22-1,52 m) away from the cleaning
surface. Then hold the lance and spray tip at a 45 degree angle to the cleaning
surface. Trigger the gun.
3. Vary the fan pattern spray angle and the distance to the cleaning surface until
optimum cleaning efficiency is achieved without damaging the surface.
DETERGENT APPLICATION
NOTE: Use only detergents formulated for pressure washers.Test detergent in an
inconspicuous area before use.
Detergents
The use of detergents can dramatically reduce cleaning time and assist in the removal
of difficult stains. Many detergents are customized for pressure washer use on
specific cleaning tasks. Pressure washer detergents are as thick as water. Using thicker
detergents – like dish soap – will clog the chemical injection system and prevent the
application of the detergent.
