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 nozzle and the cleaning
surface is another factor that affects the impact force of the
water. The impact force of the water increases as the nozzle
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 nozzle angle
to the cleaning surface and the distance from the cleaning
surface and by changing the spray nozzle. 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
nozzle you are using is appropriate for the application.
2. Place the spray nozzle approximately 4-5 feet (1,22 -
1,52 m) away from the cleaning surface. Then hold the
gun and lance 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. 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 top and work your way downward. 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 ration through the pump is approximately 10% (1
to 10).
2. Insert the filter end of the clear plastic detergent tube
into the detergent container.
3. Use the black 65° quick connect spray nozzle.
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 nozzle with another color
nozzle.
Never replace quick connect nozzle when
gun is triggered. Always engage trigger
lock on gun before removing or installing quick connect
nozzles.
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 nozzle.

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.
NOTE: The unit may also have a pressure adjustment knob on
the pump that can adjust the pressure.

FINAL RINSE

The final rinse should start at the top and work downward.
Make sure that you thoroughly rinse the surface and that you
remove all detergent.
PRESSURE RELIEF PROCEDURE
To reduce the risk of bodily injury or property damage,
always follow this procedure whenever spraying is stopped,
when work is completed, and before checking or repairing
any part of the system.
