Adjusting the Spray Fan Angle
The spray end of the wand can be rotated to
have a narrow high impact stream to a 60°
wide fan spray. (See diagram above).
A narrow stream has high impact force on
the cleaning surface and results in maximum
deep cleaning in a concentrated area.
CAUTION
The narrow high impact spray can damage some
surfaces.
A wide fan pattern distributes the impact of
the water over a larger area resulting in
excellent cleaning action with reduced risk
of surface damage. Clean large surface areas
quickly using a wide fan pattern.
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. You
can vary the impact force by controlling
1.
The nozzle’s fan pattern,
2.
The nozzle’s angle to the cleaning
surface,
3.
The nozzle’s distance from the cleaning
surface.
Never use a narrow high impact stream on a
surface that is susceptible to damage. Avoid
spraying windows with a narrow high
impact stream or turbo nozzle. Doing so may
break the glass.
1.
Before triggering the gun, adjust the
nozzle to a wide fan pattern.
2.
Place the nozzle approximately 4-5 feet
away from the cleaning surface. Then
hold the nozzle 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.
WARNING
Never slide the nozzle from low to high pressure
or from high to low pressure when the gun is
triggered.
Low Pressure Wash
Detergent Use
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
NOTE
Use only detergents specially formulated for
pressure washers.
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.
CAUTION
Never make the nozzle pressure adjustment
when the gun is triggered.
Adjusting the high-low nozzle when the gun is
triggered can result in damage to the seals in the
nozzle and will void your warranty.
