1. Check the voltmeter display for proper voltage.
2. Check the amperage of the socket, and be sure not to take a current exceed the exceed the
specified amperage. Be sure that the total wattage of all appliances does not exceed the rated
output of the machine.
3. Turn off the switch(es) of the electrical appliance(s) before connecting to the machine.
4. Insert the plug(s) of the electrical appliance(s) into the receptacle.
1 . Take the plugs out of the sockets and allow the engine to run without any charge for 1 to 2
minutes.
2. Place the engine switch on "OFF" and the set will stop.
3. Close the fuel tap.
The oil sensor detects the fall in oil in the crankcase and automatically stops the engine when the oil
level falls down below the safety limit. If the engine does not start by usual starting procedures,
check the oil level.
No work of power station in a mode "welding" and "generator" is forbidden. Before carrying out of
welding works disconnect all consumers from sockets.
1. Check the welding cable, connect the welding cables to the welder’s DC terminals
Start the engine, run at no load to warm up fully
Set the current adjust knob to the proper current level.

High altitude operation
At high altitude, the standard carburetor air-fuel mixture will be excessively rich. Performance will
decrease, and fuel consumption will increase. High altitude performance can be improved by
installing a smaller diameter main fuel jet in the carburetor and readjusting the pilot screws. lf you
always operate the generator at altitudes higher than 1000 m above sea level, have your authorized
dealer perform these carburetor modifications.
Even with suitable carburetor jetting, engine horsepower will decrease approximately 3.5% for each
300 m increase in altitude. The affect of altitude on the horsepower will be greater than this if no
carburetor modification is made.
Operation of the generator at an altitude lower than the carburetor is jetted for may result in reduced
performance,overheating,and serious engine damage
caused by an excessively lean air/fuel mixture.
