PREPARATION FOR STORAGE The following procedures should be followed prior to storage of your generator for periods of 6 months or longer. ■Drain fuel from fuel tank carefully by disconnecting the fuel line. Gasoline left in the fuel tank will eventually deteriorate making engine-starting difficult. ■Remove the carburetor float chamber and also drain the carburetor. ■Change engine oil. ■Check for loose bolts and screws, tighten them if necessary. ■Clean generator thoroughly with oiled cloth. Spray with preservative if available. NEVER USE WATER TO CLEAN GENERATOR ! ■Pull starter handle until resistance is felt, leaving handle in that position. ■Store generator in a well ventilated, low humidity area. －32－
  2. 11. TROUBLESHOOTING If the generator engine fails to start after several attempts, or if no electricity is available at the output socket, check the following chart. If your generator still fails to start or generate electricity, contact your nearest Cummins Onan dealer or service shop for further information or corrective procedures. When Engine Fails to Start : When No Electricity Is Generated at Receptacle : Check if choke lever is in its proper position. Check if fuel cock is open. Check fuel level. Check to make sure generator is not connected to an appliance. Check spark plug for loose spark plug cap. Check spark plug for contamination. Check if engine switch is in OFF. Set the choke lever to "CLOSE" position. If closed, open fuel cock. If empty, refill fuel tank making sure not to overfill. If connected, turn off the power switch on the connected appliance and unplug. If loose, push spark plug cap back into place. Remove spark plug and clean electrode. Turn engine switch to ON. Check to make sure no-fuse breaker is in the "ON" position. Check AC and DC terminals for loose connection. Check to see if engine starting was attempted with appliances already connected to generator. After making sure that the total wattage of the electrical appliance is within permissible limits and there are no defects in the appliance, turn the no- fuse breaker to the "ON" position. If breakers continue to actuate, consult your nearest servicing dealer. Secure connection if necessary. Turn off switch on the appliance, and disconnect cable from receptacle. Reconnect after generator has been started properly.
