1, every time must check the oil, in addition must be periodically replaced: a new machine for the first time the replacement is the use of 20 hours in the unit or a month later; the daily replacement for every 100 hours or every six months to completely replace a.

2, the replacement of the air filter replacement time for every 50 hours and every three months to clean up once in bad environment should be cleaned once a month.

3, every 100 hours or every six months to check the fuel filter, check the fuel filter has no water and scale, if there should be replaced fuel filter.

4, maintenance of spark plug: check the spark plug, spark in blue, strong is better; if carbon steel wire brush to remove the spark plug fouling; new spark plug replacement serious.

5, if the generator is not idle for a long time, the oil should be discharged through the carburetor fuel oil exclusion, to avoid deterioration of fuel due to blocking oil circuit. Drain the oil in the tank; put the oil in the crankcase; put the upper limit of the new oil to the oil dipstick;

Close the choke and pull up the starter handle until there is resistance. Clean the unit with a cardboard or plastic cover to prevent dust.

Common faults and their elimination:

1, the engine can not start

A, first check whether there is oil, (because the engine oil protection device, oil or oil is too dirty, the engine will automatically cut off the ignition line)

B, check the spark plug, spark in blue, strong is better; if carbon steel wire brush to remove the spark plug fouling; new spark plug replacement serious.

C, such as the above are no problem, check the carburetor, the majority of the generators are not used for long term, carburetor plug, fold cup oil gas cleaning agent on the main nozzle, spray 10 seconds a ship can solve the problem, a serious need to remove the carburetor carburetor cleaning disintegration (judging whether the internal blocking method: when starting the engine to the carburetor air inlet is sprayed with carburetor cleaner, such as starting then that is blocked to carburetor cleaning).

2, the engine has no AC output:

Whether the working voice of the generator set is normal or not;

See if there is an indication of the voltmeter, if there is indication, may be because the plug and socket contact is bad, or plug connection loose.

Open the engine control box cover to start the generator, under no-load condition to measure the AC output terminal AC output, if the output, then replace the AVR (voltage regulator)

3, the engine air filter and engine oil tank with gasoline outflow

Reason：

(1) impurity sticking machine or impurities in oil in the float valve, the float valve closed, the exhaust port is higher than the inlet end of the generator end, gasoline from the tank has to float chamber out, make more gas flow from the main nozzle, flow into the air filter, so that we can see gasoline the outflow from the air cleaner

(2) if the inlet than outlet, the float valve closed, the oil from the tank has to float chamber flow, excessive gas flow from the main nozzle, into the cylinder, if the flow of gasoline too much gasoline will flow from the oil tank.

Treatment method:

The tank will switch off, carburetor gasoline from the oil discharge screw placed at the end, take the cup, take black hose connection from the tank and the carburetor carburetor end with carburetor cleaner for carburetor gasoline oil inlet spray, and reverse moving oil float down, about 5 seconds, if any the outflow from the carburetor carburetor cleaner into a hole, and then the black hose back, open the tank switch, let the gas flowing from the carburetor oil discharge screw, put oil screw, can be restored to normal.
