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° 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. Do not use
bleach with this pressure washer unit.

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.
Once applied to a cleaning surface, detergents take time to break
down dirt and grime. Detergents work best when applied at low
pressure.
You can effectively clean surfaces by combining the chemical
action of detergents with high pressure rinses. On vertical
surfaces, apply the detergent starting at the bottom and work
your way upward. This method prevents the detergent from
sliding down and causing streaks. Begin high pressure rinsing at
the bottom and work your way upward. On particularly tough
stains, use a brush in combination with detergents and high
pressure rinsing.
1. Follow manufacturer's label directions for mixing correct
concentrations of soap/detergents. The soap detergent to
water ratio through the pump is approximately 12% (1 to 8).
2. Insert the filter end of the clear plastic detergent tube into
the detergent container.
3. Install 65º (Black) Low Pressure Detergent Tip in the quick
connect fitting on the end of the lance.
NEVER replace quick connect tip when gun is
triggered. Always engage trigger lock on gun
before removing or installing quick connect tips.

General Cleaning Tips

1. Apply the detergent so that it thoroughly covers the cleaning
surface. Apply the detergent from bottom to top to prevent
the detergent from sliding down and streaking. Wait a
couple of minutes for the detergent to break down the dirt
and grime. Use a brush to lightly scrub heavily soiled areas.
Never allow the detergent to dry on the cleaning surface.
2. To rinse: replace black 65° spray tip with another color tip.
Never replace quick connect tip when gun
is triggered. Always engage trigger lock on gun
before removing or installing quick connect tips.
3. After using detergents, flush the suction system by placing
the detergent suction tube into a bucket of clean water and
spraying with the black spray tip.

CLEANING POWER

The easiest way to regulate the cleaning power of your pressure
washer is by changing the distance from the surface you are
cleaning. Begin spraying with a wide fan pattern while standing
several feet from the surface. Slowly move closer to the object
you are cleaning, adjusting the spray pattern as necessary, until
you find the most effective cleaning technique.
