instructions for more information.

3. Connect cleaning nozzle, chemical injector control nozzle, or accessory
nozzle or attachment to gunvalve extension quick coupler (Fig. 2.2).

through the system.
2. Allow machine to run for 1 minute without load to cool before stopping.
3. Operate “STOP” lever or switch to shut off machine (See engine instruction manual).
4. Pull recoil starter until compression resistance is felt. Store the machine in this position to help prevent
valve warpage or sticking.
5. Close Fuel Valve. For Electric Models Turn “ON/OFF” switch on machine to the “OFF” position.
FAILURE TO CLOSE THE FUEL VALVE ON THE ENGINE CAN CAUSE FUEL LEAKAGE
WHEN THE MACHINE IS BEING TRANSPORTED!
