dipstick.

If oil level is between the 

LOW

 and 

HIGH

 mark on dipstick:

1.Add oil to bring level to 

HIGH

 mark.

2.Restart engine and if the engine stops again a low oil condition may still exist. DO NOT try to restart 
the engine.

Overloading a generator in excess of its rated wattage capacity can result in damage to the 
generator and to connected electrical devices. To prolong the life of your generator and attached 
devices, follow these steps to add electrical load: 
1. Start the generator with no electrical load attached. 
2. Allow the engine to run for several minutes to stabilize. 
3. Plug in and turn on the first item. It is best to attach the item with the largest load first. 
4. Allow the engine to stabilize. 
5. Plug in and turn on the next item. 
6. Allow the engine to stabilize. 
7. Repeat steps 5-6 for each additional item.

Do Not Overload Generator

Overload Operation

The overload indicator light will turn on when the load exceeds 1764W(approximately). If the load 
exceeds 1860W(approximately), the light will blink and cut power to the receptacles in 30 seconds. 

1. Disconnect any electrical devices, and then stop the engine.

3. Inspect the Air Inlet and Control Panel for any blockage. Remove blockage if found.
4. Restart Engine.

How to Correct

2. Reduce the total wattage of connected electrical devices until it is within the generator’s rated output.

Parallel Operation

Any  two  FIRMAN  inverter  generators  with  parallel  ports,  including  two  FIRMAN  inverters  model 
W01785 can be paralleled to increase the total available electrical power to 3100 Watts. A FIRMAN 
Parallel kit (not included) is required for parallel operation. For Kit availability, call customer Service at 
1-844-347-6261 or visit: www.firmanpowerequipment.com.
