7. Remove dipstick/oil plug (H) from plastic bag and
install into pump, tighten securely.
NOTE: The shipping plug must be removed and
replaced with the dipstick/oil plug before operat-
ing pressure washer.
WARNING: Risk of bursting. Use a tire pressure
gauge to check the tires pressure before each use and while inflating
tires; see the tire sidewall for the correct tire pressure.
NOTE: Air tanks, compressors and similar equipment used to
inflate tires can fill small tires similar to these very rapidly. Adjust
pressure regulator on air supply to no more than the rating of the
tire pressure. Add air in small increments and frequently use the
tire gauge to prevent over inflation.
OPERATION
Pressure Adjustments
The pressure setting is preset at the factory to achieve op ti mum pres-

1. Back away from the sur face to be cleaned. The further away you
are, the less the pressure will be on the surface to be cleaned.
