minutes

  in  the  event  of  any  unwanted shutdown 

such as low oil, running out of fuel(gasoline or LPG), 

or  any other unwanted shutdown. This is a reminder 

that  the  generator is  switching to 

Battery Power

  The  generator  should  be  checked 

Starting the engine successfully during these 

minutes

 will turn the indicator light 

GREEN

.

Starting the engine unsuccessfully or not attempting 

to start the engine at all during these 

4 minutes

” POSITION.

Unwanted Shutdown:

The generator cannot be started during or after 

the 

4 minutes

 of 

FLASHING

 mode unless the fuel 

selector switch is turned to the "

OFF

" position and 

then turned back to the “

GAS

” or “

LPG

” position. 

for any unwanted shutdown.

This generator is equipped with an automatic 

battery  charging  circuit  and  the  battery  will 

receive  a  proper  charge  when  the  engine  is 

running to keep the battery charged.

Low Oil Shutdown

If the engine oil drops below a preset level, an 

oil switch will stop the engine. Check oil level 

with dipstick.

If oil level is between LOW and HIGH mark on 

dipstick:

1.DO NOT try to restart the engine.

2.Contact an Authorized FIRMAN Service Dealer.

3.DO NOT operate engine until oil level is 

   corrected.

If oil level is below LOW 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.

3.Contact an Authorized FIRMAN Service Dealer.

4.DO NOT operate engine until oil level is 

   corrected.

Do Not Overload Generator

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.
