English 3. Install low-pressure (black) nozzle into quick connect fitting of spray wand, refer to Spray Wand Nozzles. NOTE: Chemicals and soaps will not siphon if the black soap nozzle is not installed on the spray wand. 4. After use of chemicals, place chemical hose into container of clean water and draw clean water through chemical injection system to rinse system thoroughly. If chemicals remain in the pump it could be damaged. Pumps damaged due to chemicals will not be covered under warranty. Starting Warning: To reduce the risk of injury, read the pressure washer instruction manual and the engine instruction manual before starting pressure washer. DANGER: Risk of fluid injection and laceration. When using the high-pressure setting, DO NOT allow the high-pressure spray to come in contact with unprotected skin, eyes, or with any pets or animals. Serious injury will occur. • Your washer operates at fluid pressures and velocities high enough to penetrate human and animal flesh, which could result in amputation or other serious injury. Leaks caused by loose fittings or worn or damaged hoses can result in injection injuries. DO NOT TREAT FLUID INJECTION AS A SIMPLE CUT! See a physician immediately! DANGER: Carbon Monoxide. Using an engine indoors can kill you in minutes. Engine exhaust contains high levels of carbon monoxide (CO), a poisonous gas you cannot see or smell. You may be breathing CO even if you do not smell engine exhaust. • Breathing ex­haust fumes will cause se­ri­ous injury or death! En­gine exhaust con­tains carbon mon­ox­ide, an odorless and deadly gas. • Operate pressure washer in a well-ventilated area. Avoid en­closed areas such as ga­rag­es, base­ments, etc. • Never op­er­ate unit in or near a lo­ca­tion occupied by humans or animals. WARNING: Risk of fire, asphyxiation and burning. Never fill fuel tank when engine is running or hot. Do not smoke when filling fuel tank. • Never fill fuel tank completely. Fill tank to 1/2" (12.7 mm) below bottom of filler neck to provide space for fuel expansion. Wipe any fuel spillage from engine and equipment before starting engine. • DO NOT let hoses come in contact with very hot engine muf- fler during or immediately after use of your pressure washer. Damage to hoses from contact with hot engine surfaces will NOT be covered by warranty. NOTICE: Never pull water supply hose to move pres­sure washer. This could damage hose and/or pump inlet. • DO NOT use hot water, use cold water only. • Never turn water supply off while pressure washer engine is running or damage to pump will result. • DO NOT stop spraying water for more than two minutes at a time. Pump operates in bypass mode when spray gun trigger is not pressed. When the temperature inside the pump rises too high the thermal relief valve (T) will open and release a gush of water in an effort to lower T the temperature inside the pump. The thermal relief valve will then close. If pump is left in bypass mode for more than two minutes internal components of the pump can be damaged. 13
