PRIOR
to starting engine.
10. Start the engine by following this procedure:
- Turn the ON/OFF switch to ON.
- Turn the GAS to ON.
- Turn the CHOKE to FULL.
- Push the THROTTLE lever to the ON position.
- Pull the STARTING cord.
- Once the engine has started, reduce the CHOKE until it is OFF, and open the THROTTLE to
full ON.
Use these instructions in conjunction with instructions provided in the Honda manual.
11. At this point, the gun is triggered to evacuate any remaining air in the system. Then trigger the
gun and begin turning the BLACK unloader knob in a clockwise direction as far as it will turn.
You should now have full pressure.
12. To introduce chemicals/detergent to the spray,
- Turn unit off, and trigger gun to relieve all internal fluid pressure.
- Re-connect the chemical injector components as removed in step 8.
- Connect the detergent/chemical suction line to the fitting marked “Injector” and place the filter
end into the chemical/detergent jug.
- Install “Black” injector tip into gun. VERY IMPORTANT.
- Re-start pump and set pressure to low.
Injector siphoning is best at very low pressure. Once the injector material stream has been
established, the pump operating pressure can be increased.
