Water Supply (Cold Water Only)• Water hose must be at least 3/4 inch

in diameter.• Flow rate of water supply must not fall

below 2.5 GPM (gallons per minute).• Flow rate can be determined by running

the water for one minute into an empty5-gallon container.

• The water supply temperature must notexceed 104°F/40°C.

• Never use the pressure washer to draw in water contaminated with solvents,e.g. paint thinners, gasoline, oil, etc.

Step 9 Connect thehigh pressure hose to theunit’s high pressure outlet.

Step 3Connect gardenhose to the coldwater sourceand turn wateron completely.

Never use hotwater.

Step 4 Trigger the gunto eliminate trapped air, waitfor a steady flow of water toemerge from the spraynozzle.

Step 5 Slide the chokelever to the left to the “CLOSED”position (on a warm engine, leavethe choke lever in the openposition).

Step 9 Adjust pressurecontrol to desired setting.

Step 6 Slide the fuelvalve to the “ON” position. Slide the throttle lever leftabout 1/3 of the way towardthe fast position.

Step 7 Turn the engineswitch to the “ON” position.

Step 8 Pull the starterhandle. If the engine fails tostart after 3 pulls, squeeze the trigger gun to releasepressure, and repeat step.
