FOREWORD Thank you for purchasing a Makita generator. This manual covers operation and maintenance of the Makita generators. All information in this publication is based on the latest production informa- tion available at the time of approval for printing. Pay special attention to statements preceded by the following words:...
1. SAFETY PRECAUTIONS Do not operate the generator near gasoline or gaseous fuel because of the potential danger of explosion or fire. Do not fill the fuel tank with fuel while the engine is running. Do not smoke or use open flame near the fuel tank. Be careful not to spill fuel during refueling. If fuel is spilt, wipe it off and let dry before starting the engine.
Page 12
Pay attention to the wiring or extension cords from the generator to the con- nected device. If the wire is under the generator or in contact with a vibrating part, it may break and possibly cause a fire, generator burnout, or electric shock hazard. Replace damaged or worn cords immediately.

CHECKING COMPONENT PARTS Check following items before starting engine: Fuel leakage from fuel hose, etc. Bolts and nuts for looseness. Components for damage or breakage. Generator not resting on or against any adjacent wiring. CHECK GENERATOR SURROUNDINGS. WARNING Make sure you review each warning in order to prevent fire hazard. Keep area clear of in flammables or other hazardous materials.
Page 19
BATTERY INSTALLTION (Electric starter model) Recommended Battery: A capacity of 12V-24AH or larger. WARNING Death, personal injury and/or property damage may occur unless instruc- tions are followed carefully. Use battery of recommended capacity. Turn the starter switch to the "STOP" position when mounting or dis- mounting battery.

Page 26
Stop the generator immediately, check the appliance and / or generator for overloading or detect and have repaired as necessary by Makita factory or authorized service center. CAUTION The duplex 120V receptacle is protected by a GFCI (Ground Fault Circuit Interrupter).
Page 27
GFCI RECEPTACLE After starting the engine, check the GFCI for proper functioning by the following test procedure. Push yellow TEST button, The red RESET button will pop out exposing the word TRIP. Power is now off at the outlets protected by the GFCI, indicating that the device is functioning properly.

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 use of improper size or gauge of extension cords may cause unsafe or ineffi- cient operation of your tool or appliance.
7. SPARK ARRESTER SPARK ARRESTER In a dry or wooded area, it is recommendable to use the product with a spark arrester. Some areas require the use of a spark arrester. Please check your local laws and regulations before operating your product. The spark arrester must be cleaned regularly to keep it functioning as designed.
8. MAINTENANCE SCHEDULE MAINTENANCE, REPLACEMENT OR REPAIR OF THE EMISSION CONTROL DEVICES AND SYSTEMS MAY BE PERFORMED BY ANY NONROAD ENGINE REPAIR ESTAB- LISHMENT OR INDIVIDUAL.

Do not pour it down into sewage drains, onto garden soil or into open streams. Your local zoning or environmental regulations will give you more detailed instructions on proper disposal. *NOTE: 2. As to the procedures for these items, please refer to the SERVICE MANUAL or consult your nearest Makita service dealer.
6. If contaminated or deteriorated oil is used or the quantity of the engine oil is not sufficient, the engine damage will result and its life will be greatly shortened. CLEANING AIR CLEANER (Model G2800R) Maintaining an air cleaner in proper condi- tion is very important. Dirt induced through improperly installed, improperly serviced or inadequate ele- ments damages and wears out engines.
(b) Adjust the electrode gap. ELECTRODE GAP Electrode gap Model Spark plug Electrode gap G2800R 0.02 to 0.03 in. NGK BR6HS G4100R (0.6 to 0.7 mm) G4101R 0.03 in. G6100R NGK BR6ES (0.7 to 0.8 mm)
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. (c) Tightly fasten the cup to main body, making sure to avoid fuel leak.
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 engine-starting difficult.
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 : Set the choke lever to "CLOSE"...
