5. Wash from the bottom to the top, using side to side
motions. This washes away heavy dirt and allows the
detergent to soak as you work to ward the top.
6. Do not wash at a 90
o
angle to the work (straight at
it). This will allow water to splash back at you and
reduces your cleaning power. Wash at a 30
o

o
an gle to the work. This will allow the water to splash
away from you and the water will wash the dirt away
faster and eas i er.

wide path. Overlap spray paths for complete cover-
age wash ing from side to side, using slow, steady
motions.
8. The nozzle should be 12" to 24" from work, closer
for tough areas. Be careful on painted or del i cate
sur fac es, the pressure may damage surface if noz zle
is too close.
9. Small parts should be washed in a basket so the
pres sure does not push them away. Larg er, light weight
parts should be clamped down so the pres sure does
not push them away.
10. Turn the side de ter gent control knob clockwise (CW)
for detergent decrease. Wait for de ter gent to clear.
Always rinse with cold water after using de ter gent.
Rinse from the top to the bottom to pre vent de ter gent
from dripping onto a rinsed area. For the best re sults,
con tact your Hotsy dealer to help you select the best
de ter gent for your application.
