DEGREASING WITH THE AIR PRESSURE WASHER
The Air Pressure Washer works best using Sears
specially formulated concentrated degreaser, which can
be purchased in the Sears lawn and garden department.
Follow the directions supplied with the degreaser for the
proper mix ratio.
Most common household degreasers, are not formulated
and concentrated 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 degreasing efficiency.
NOTE:
If you do not use Sears degreaser, be sure the
degreaser you do use is specially formulated and concen-
trated for use with this type of equipment. Mix the chosen
degreaser with water (1 part degreaser to 4 parts water)
to reduce the viscosity (consistency or thickness) of the
mixture.
1. Prepare a mixture of degreaser 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 degreaser/water mixture.
3. For best degreasing performance, set your air com-
pressor to the maximum pressure available from
your air compressor not to exceed 175 psig. Be sure
the air and water controls on the Air Pressure Washer
are in the "Off" position.
4. Turn on your air compressor.
5. Begin the degreasing procedure by adjusting the air
control knob and the soap/chemical control knob
until they begin spraying the solution. 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 degreaser solution 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 degreaser solution and dirt from the surface
you are degreasing.
10. When rinsing 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.
CLEANING AND STORAGE
Clean the exterior of the Air Pressure Washer and draw
hose with a damp cloth, soap and water.
Fill a container with clean water, insert the free end of the
chemical draw hose into the water and rinse the internal
system.
Disconnect all hoses from the Air Pressure Washer.
Store the Air Pressure Washer away from open flames
and heat.
To prevent freezing in cold weather, make sure all liquids
are drained from your Air Pressure Washer before stor-
age.
Store with the air, water and chemical control knobs in the
open or "On" position. Hang vertically with the foliage
nozzle down.
Do not clean a hot engine. Engine block
can crack or other damage can occur.
Wait until the engine has cooled at least
one hour. Cover the battery and carbure-
tor throat when you clean the engine.
