CORRECTION
• Open knob gradually until you
achieve desired flow rate (2½
turns maximum).
• Add water to thin the solution.
• Use Sears special cleaner/
degreaser.
• Turn water control knob "OFF".
Only air and chemical control
knobs should be "ON".
• Close knob until sputter stops.
• Air compressor too small for
application. For best performance,
use 3½ or larger tank-type air
compressor delivering 125 psig.
• Use maximum water pressure
available (not ot exceed 100 psig).
• Open both knobs fully.
• Scrub surface with rag or sponge
to loosen dirt then rinse with air
and water control knobs "ON".
• None, the pulsations actually im-
proves the cleaning performance.
• To wash or spray chemically use
chemical and air control knobs
"On" only. To rinse, use water and
air control knobs "On" only.
