EG781AE ce_GU6837 10.1.25 1:36 PM ページ21 Some appliances need a "surge" of energy when starting. This means that the amount of electrical power needed to start the appliance may exceed the amount needed to maintain its use. Electrical appliances and tools normally come with a label indicating voltage, cycles / Hz, amperage (amps) and electrical power needed to run the appliance or tool.
EG781AE ce_GU6837 10.1.25 1:36 PM ページ22 VOLTAGE DROP IN ELECTRIC EXTENSION CORDS When a long electric extension cord is used to connect an appliance or tool to the generator, a certain amount of voltage drop or loss occurs in the extension cord which reduces the effective voltage available for the appliance or tool. The chart below has been prepared to illustrate the approximate voltage loss when an extension cord of 300 feet (approx. 100 meters) is used to connect an appliance or tool to the generator.

Spark plug : BR-6HS (NGK) CLEANING FUEL STRAINER Dirt and water in the fuel are removed by the fuel strainer. (a) Remove the strainer cup and throw away water and dirt. (b) Clean the screen and strainer cup with gasoline.
EG781AE ce_GU6837 10.1.25 1:36 PM ページ28 CHECKING CARBON BRUSH Brush Maintenance Essentials (Effective Length) The brush is the area which touches the slip ring, and its surface must be kept smooth. If it is not smooth then carbon and other substances will adhere between the brush and slip ring. This must be buffed with sandpaper or the like because it is hazardous. The usable length of the brush is 5~11mm, so if the brush is 5mm long or less replace it with a new one.
Brush Maintenance Essentials (Disassembly and Assembly) Disassembly 1. Remove the two flange bolts (M5 x 20), then remove the bracket cover. Brush 2. Remove the two flange bolts (M5 x 16), then remove the brush. Slip ring Assembly 1. While pressing the brush against the slip ring, secure it (1.5~2N・m) by tightening it with the two flange bolts (M5 x 16). When doing so, confirm that the brush is in the proper position relative to the slip ring. 2.
EG781AE ce_GU6837 10.1.25 1:36 PM ページ30 10. 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 enginestarting difficult. Drain screw Remove the carburetor float chamber and also drain the carburetor. Change engine oil.
EG781AE ce_GU6837 10.1.25 1:36 PM ページ31 When 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 Makita factory or authorized service center for further information or corrective procedures. When Engine Fails to Start : Check if choke lever is in its proper position. Set the choke lever to "CLOSE" Check if fuel valve is open.
