Washing With The Air Pressure Washer; Spraying Foliage With The Air Pressure Washer - Craftsman 919.716170 Assembly & Operation Manual

WASHING WITH THE AIR PRESSURE WASHER

The Air Pressure Washer works best using Sears spe-
cially formulated concentrated detergent, which can be
purchased in the Sears lawn and garden department.
Follow the directions supplied with the detergent for the
proper water/detergent mix ratio.
Most common household detergents are not formulated
and for use in your Air Pressure Washer. They are too
heavy or thick to pass through your Air Pressure Washer
and if they are diluted with water, they lose their cleaning
efficiency.
NOTE: If you do not use Sears detergent, be sure the
detergent you do use is specially formulated and concen-
trated for use with this type of equipment. Mix the chosen
detergent with water (1 part detergent to 8 parts water) to
reduce the viscosity (consistency or thickness) of the
mixture.
1. Prepare a mixture of detergent in a 1-gallon plastic
bucket or suitable container.
2. Attach the garden hose (cold or warm water), air
hose, and chemical draw hose to the Air Pressure
Washer. Place the free end of the chemical draw
hose into the detergent/water mixture.

SPRAYING FOLIAGE WITH THE AIR PRESSURE WASHER

MANY CHEMICALS ARE TOXIC OR IRRITATING. READ THE SAFETY LABEL OR INSTRUCTIONS
FOR EVERY CHEMICAL YOU SPRAY. CAREFULLY FOLLOW ALL INSTRUCTIONS REGARDING
SKIN, EYE AND RESPIRATORY PROTECTION.
1. Prepare a mixture of chemical and water in a 1-gallon
bucket or suitable container. Carefully follow the
directions on the chemical container for the proper
water/chemical ratio.
NOTE: Thick or heavy chemicals must be mixed with
water to reduce their thickness. Heavy materials will not
pass through the Air Pressure Washer.
2. Attach the chemical draw hose and the air hose to the
Air Pressure Washer. Place the free end of the
chemical draw hose into the chemical/water mixture.
3. DO NOT attach a hose to the garden hose connector
for foliage spraying. Be sure the water control knob is
in the "Off" position.
3. For best performance, set your compressor to the
maximum pressure available from your air compres-
sor not to exceed 175 PSIG. Be sure the air and water
controls on the Air Pressure Washer are in the "Off"
position.
4. Turn the water source fully on and turn on your air
compressor.
5. Begin the washing procedure by adjusting the air
control knob and the soap/chemical control knob
until they begin spraying the solution onto the surface
to be washed. The water knob should be OFF.
Continue spraying until the surface is completely
covered with the solution.
6. To stop spraying, turn the soap/chemical control
knob and the air control knob to the "Off" position.
7. Let the soap remain on the surface for about 30
seconds. A certain amount of wiping will be required
for most types of foreign matter.
8. Fully open both air and water control knobs.
9. Rinse the soap and dirt from the surface you are
washing.
10. When rinising or washing surfaces with an air/water
mixture, the Air Pressure Washer will pulsate under
certain conditions. This is normal, especially at high
air water pressures. The pulsations indicate the air
and water are mixing effectively and should improve
the cleaning action of the spray.
4. For optimum performance set your air compressor
pressure between 75 and 125 psig. Be sure the air
control knob is in the "Off" position.
5. Extend the Foliage Nozzle out as far as it will go.
6. Turn on the air compressor.
7. Begin the spraying procedure by adjusting the air
control knob and the soap/chemical control knob
until you are spraying a mist. You may vary the mist
pattern by pulling the foliage nozzle in slightly.
8. To stop spraying, turn the air control knob and the
soap/chemical control knob to the "Off" position.
