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,

4.1bar) 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 Technical Data on page 15.
