High pressure fluid can dislodge a loose coupling or allow high pressure spray to be emitted from the coupling. NEVERuse a damaged hose. Before each use, check entire hose for cuts, leaks, abrasion, bulging cover , or damage or movement of the hose couplings. If any of these conditions exist, replace the hose immediately. DO NOTtry to recouple high pressure hose or mend it with tape or any other device. A repaired hose cannot contain the high pressure fluid. HANDLE AND ROUTE HOSES CAREFULLY.Do not pull on hoses to move the pressure washer. Do not use chemicals which are not compatible with the inner tube and cover of the hose. DO NOTexpose Graco hose to temperatures above 200. F (93. C) or below –40F (–40. C). FUEL AND EMISSION HAZARDS NEVERfill the fuel tank while the unit is running or hot. The fuel used in this unit is combustible and when spilled on a hot surface can ignite and cause a fire. ALWAYSfill tank slowly to avoid spilling. NEVERoperate the unit in a closed building. The exhaust contains carbon monoxide, a poisonous, odorless, invisible gas which can cause serious injury or death if inhaled. NEVERalter the throttle setting, which is factory set. Tampering with this adjustment can damage the pressure washer and will void the warranty. ........... MOVING PARTS HAZARD MOVING PARTS HAZARD Moving parts can pinch or amputate fingers or other body Pressure Relief Procedure before checking or parts. KEEP CLEAR of moving parts when starting or servicing the pressure washer to prevent discharging operating the pressure washer. high pressure fluid from the gun. NEVERoperate the pressure washer without all guards and interlocks installed and functioning.

CAUTION: Alerts user to avoid or correct conditions that could cause damage to or destruction of equipment. IMPORTANT United States Government safety standards have been adopted under the Occupational Safety and Health Act. These standards—particularly the General Standards, Part 1910, and the Construction Standards, Part 1926—should be consulted. . . .......... INSTALLATION Figure 1 TEE HANDLE (3040 ONLY) SPRAY GUN SPRAY HOSE HIGH PRESSURE HOSE CONNECTION HOSE RACK INLET WATER CONNECTION 3/4” GARDEN HOSE Check for Shipping Damage The unit should be checked for any damage that may have occurred in shipping. Any damage should be noted and the carrier notified immediately. Set Up If you are using a downstream chemical injector, install it between the pump unloader and the high pressure hose, using the quick couplers provided. 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 performance, and chemical injector performance, if used. Install the appropriate spray tip on the wand. See Installing and Changing Spray Tips. If you are using a sandblaster kit, see its separate manual for installation instructions. Connect to Water Supply CAUTION Before attaching to the water supply, check your local plumbing code regarding cross– connection to the water supply. A backflow preventer P/N 801–133 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 (4.1 bar) a regulating water valve P/N 800–258 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 inch (19 mm) ID from the water supply to the unit’s 3/4 inch garden hose inlet. The supply hose should not be more than 50 ft (15 m) long. NOTE: The water source at the unit must have a minimum flow rate equal to that of the unit (see Technical Data, inside back cover). STARTUP STARTUP Use this procedure whenever starting the pressure washer to help insure that the unit is ready to operate and starting is done safely. 1. Check oil levels. Engine: Add SAE 30 or 10W–30 weight detergent oil as necessary. Pump: Add SAE 20 or 30 weight non–detergent oil as necessary. NOTE: Some units are equipped with a low–oil sensor that shuts the engine of f if the oil level falls below a certain level. If the unit stops unexpectedly, check both the oil and the fuel levels. Check the oil level each time the unit is refueled. 2. Check fuel level. WARNING DO NOT refuel a hot engine. Refueling a hot engine could cause a fire. Use only fresh, clean regular or unleaded gasoline. Close the fuel shutoff valve during refueling. 3. Turn on the water supply. CAUTION Never run the unit dry . Costly damage to the pump will result. Always be sure the water supply is completely turned on before operating. 4. Trigger the gun until water sprays from the tip indicating that the air is purged from the system. 5. Open the fuel shutof f valve and be sure ...
