4. PRE-OPERA TION CHECKS − 7 − ENGLISH Upper level Oil filler cap (Oil gauge) Lower level CHECK ENGINE OIL Before checking or refilling oil, be sure generator is located on stable and level surface with engine stopped. ■ Remove oil filler cap and check the engine oil level.
− 8 − ■ Check fuel level at fuel level gauge. ■ If fuel level is low , refill with unleaded automotive gasoline. ■ Be sure to use the fuel filter screen on the fuel filter neck.
− 9 − ENGLISH CHECKING COMPONENT P ARTS 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.
− 10 − GROUNDING THE GENERA TOR ■ To ground the generator to the earth, connect the grounding lug of the generator to the grounding spike driven into the earth or to the conductor which has been already grounded to the earth.
5. OPERA TING PROCEDURES − 11 − ENGLISH (a) T urn the Engine switch to the position "ON". (b) T urn the AC circuit breaker to the position "OFF".
− 12 − Pull briskly (e) [ Recoil starter model] Pull the starter handle slowly until passing the compression point (resistance will be felt), then return the handle to its original position and pull briskly . ■ If the engine fails to start after several attempts, repeat above procedures with choke lever returned to "OPEN" position.
− 13 − ENGLISH (g ) After the engine started, return the choke lever gradually to "OPEN" position. Choke lever CLOSE OPEN (h) W arm up the engine without a load for a few minutes.
− 14 − (a) Make sure the pilot lamp is turned on. (b) T urn off the switch (es) of the electrical appliance (s) before connecting to the generator .
− 15 − ENGLISH TABLE 1 NOTE : When the AC circuit breaker turns off during operation, the generator is over loaded or the appliance is defective. 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 .
− 16 − (d) T urn the AC circuit breaker to the position "ON". (e )T urn on the switch of the appliance. ON ON OFF GFCI RECEPT ACLE After starting the engine, check the GFCI for proper functioning by the following test procedure. ■ Push blue TEST button, The red RESET button will pop out exposing the word TRIP .
− 17 − ENGLISH Switch position Lower V oltage Receptacle Higher V oltage Receptacle 120V Activated full rated output N.A 120/240V Activated half of rated output Activated full rated output FULL POWER SWITCH (Except EG301A) Select the voltage using the FULL POWER SWITCH in accordance with the electrical appliance.
− 18 − (2) DC APPLICA TION (Only for charging 12 volt battery) DC receptacle (Only for charging 12 volt battery) For charging 12 voltage battery , 12V -8.3A (100W) of maximum AC power can be taken out from the DC receptacle by means of the exclusive DC cable.
− 19 − ENGLISH ■ Do not use both AC and DC output at the same time. ■ Install correct positive (red) or negative (black) cable to the correct polarity on the battery . ■ Connect and disconnect DC cable with engine stopped. ■ An explosive hydrogen gas is discharged through vent holes in the battery during the charging process.
− 20 − STOPPING THE GENERA T OR (a) T urn off the power switch of the electric equipment and unplug the cord from receptacle of the generator . (b) T urn the AC circuit breaker to the "OFF" position. (c) Allow the engine about 3 minutes to cool down at no-load before stopping.
6. W A TT AGE INFORMA TION − 21 − ENGLISH 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.
VOL T AGE 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.
7. SP ARK ARRESTER − 23 − ENGLISH 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 .
DAIL Y INSPECTION Before running the generator , check the following service items: Excessive vibration,noise Clean air cleaner element Safe surroundings Enough clean engine oil Leakage of gasoline an.
− 25 − ENGLISH *Note: 1. Initial oil change should be performed after first twenty (20) hours of operation. Thereafter change oil every hundred (100) hours. Before changing oil, check for a suitable way to dispose of old oil. Do not pour it down into sewage drains, onto garden soil or into open streams.
ENGINE OIL CHANGE ■ Change engine oil every 100 hours. (For new engine, change oil after 20 hours.) (a) Drain oil by removing the drain plug and the oil filler cap while the engine is warm. Oil drain plug (b) Reinstall the drain plug and fill the engine with oil until it reaches the upper level on the oil filler cap.
− 27 − ENGLISH CLEANING AND ADJUSTING SP ARK PLUG (a) If the plug is contaminated with carbon, remove it using a plug cleaner or wire brush. (b) Adjust the electrode gap to 0.6 to 0.7 mm (0.024 to 0.028 in.). Gap 0.6 to 0.7 mm ( 0.024 to 0.028 in.
− 28 − This is done because if the length of the brush gets any shorter , its contact pressure with the slip ring will decrease, resulting in a drop in generator efficiency and the output voltage. Check the brush every 500 hours to confirm its length.
− 29 − ENGLISH Brush Maintenance Essentials (Disassembly and Assembly) Disassembly 1. Remove the two flange bolts (M5 x 20), then remove the bracket cover . 2. Remove the two flange bolts (M5 x 16), then remove the brush. Assembly 1. While pressing the brush against the slip ring, secure it (1.
10. PREP ARA TION FOR ST ORAGE − 30 − 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.
11 . TROUBLESHOOTING − 31 − ENGLISH When generator engine fails to start after several attempts, or if no electricity is available at the output socket, check the following chart.
