GENERAL WASHING
TECHNIQUES
Test pressure and spray pattern on hard surface (i.e. ce-
ment) to gauge distance and impact of water spray.
Hold spray nozzle approximately one foot from surface
being cleaned. For best surface cleaning action, spray
at a slight angle.
To change spray nozzle for a different pattern it is recom-
mended that you turn off engine and squeeze spray gun
trigger to release hose pressure. Pull back on quick cou-
pler at end of wand and exchange nozzle. Make sure
nozzle is seated securely. Restart engine.
Use the detergent injector to apply detergent. Wash from
the bottom and work up. Allow detergent to set
5-10 min. on surface. Rinse from top down.
NOTE: If pressure washer is running and not being
used for more than 2 minutes, turn off engine.
