Check for Shipping Damage
Check the pressure washer for shipping damage. If
anything is damaged, notify the carrier immediately.
Set Up
Connect the high-pressure hose between the pump
outlet and the gun inlet. Both of these connections are
made with quick couplers.
CAUTION
Up to 100 ft (30 m) of high-pressure hose may
be used. Longer hoses may affect sprayer and
chemical injector performance.
Install the appropriate spray tip on the wand. See
Installing and Changing Spray Tips on page 6. If
you use a sandblaster kit, see its separate manual for
installation instructions.
Connect to Water Supply
CAUTION
Before you connect to the water supply, check
your local plumbing code regarding cross
connection to the water supply. Backflow
Preventer 801133 is available to prevent
backflow of contaminated water into the fresh
water supply. Install it upstream from the pump.
If inlet water pressure is over 60 psi (414 kPa,
4.1 bar) Regulating Water Valve 800258 must be
installed at the garden hose connection.
Do not exceed 160 _ F (70_ C) inlet water
temperature.
Connect a hose with at least a 3/4-in. (19 mm) ID from
the water supply to the 3/4-in. garden hose inlet. The
supply hose should not be more than 50 ft (15 m) long
NOTE: The water source must have a minimum flow
rate equal to that of the pressure washer. See
