IMPORTANT

1. When the pressure control valve is changed to INSECTICIDE or HERBICIDE,
with the throttle being fully open at HIGH PRESSURE positon of pressure control
valve handle, the engine speed will become too high, corresponding to the extent
of lowered pressure. Therefore, use the equipment with the throttle lever
somewhat turned back from the fully opened condition, when the equipment is
used at the position for INSECTICIDE or HERBICIDE.

2. Be careful of the amount of fuel in the tank, and refill it when it becomes low.

To Stop:

Temporary halt during operation:

1. Close the spray gun, and return the throttle lever to low speed.

2. Press the engine stop button.

3. After the engine stops, set the sprayer down and close the fuel cock.

Stopping the sprayer after completing spraying:

1. Remove the chemical tank drain cap, drain off all of the chemical

2. Fill the chemical tank with clean water, operate the engine, and clean the pump
and hose interior by spraying the clean water. Drain off the remaining water
through the drain.

Start the engine at just less than high speed for 15-20 seconds to spray out the water in the
spray hose and nozzle. When water stops coming from the nozzle, turn off the engine at
once.
