Maintenance and Repair

Inspect and maintain your generator as specified below in order to keep it in safe and optimal 
working order.  Follow all safety rules and recommended maintenance steps. 

 

 

  WARNING 

ALWAYS shut off the engine, disconnect the spark plug(s) and discharge the capacitor 
before cleaning, adjusting, or servicing the generator.  Make sure all guards and shields are 
replaced before using.

 

 

   

 

Note:  The generator head is brushless and maintenance free.  The bearing is a heavy-duty 
sealed ball bearing which requires no maintenance or lubrication. 

 

Maintenance and Repair  

Follow safety rules 

Read and follow these safety rules whenever you will be servicing the 
generator: 

 

Turn off generator.

  Always turn off generator and remove spark plug(s) or 

spark plug wire(s) before working on the engine or generator to prevent 
accidental starting. 

 

Discharge capacitor.  

When the generator is shut down, the capacitor may 

maintain a charge.  Always discharge the capacitor before working on the 
generator head to prevent electrical shock.  Discharge using a screwdriver with an 
insulated handle.  While wearing safety glasses, touch opposite terminals of the 
capacitor together with the tip of the screwdriver.  If there is stored charge in the 
capacitor, a spark will be generated thereby discharging the capacitor. 

 

Replace guards.

  Make sure all guards and shields are replaced after servicing 

the generator. 

 

Repair.

  Major service, including the installation or replacement of parts, should 

be performed only by a qualified electrical service technician.  Obtain factory 
approved parts from NorthStar Product Support at 1-800-270-0810. 

 

 

Replacement parts

.  If a part needs replacement, only use factory approved 

repair parts.  Replacement parts that do not meet specifications may result in a 
safety hazard or poor operation of the generator and will void the warranty.

 

Perform engine 
maintenance 

Perform engine maintenance as specified in the engine owner’s manual.  

Engine maintenance items include: 

1.

 

Changing oil and oil filter 

2.

 

Air filter check/replacement 

3.

 

Fuel filter check/replacement 

4.

 

Fuel tank cleaning. 

Check receptacles 

Check receptacles before each use to make sure they are not cracked or 
broken.   

If a receptacle is cracked or otherwise damaged, do not use until replaced 
with an authorized factory part.  Using cracked or damaged receptacles can be 
both dangerous to the operator and destructive to the equipment. 
 

Inspect fuel system / 
check for leaks 

Inspect the fuel system and check for leaks on a regular basis. 

 

1)

 

Inspect the entire fuel system.  Look for: signs of leaks or deterioration, 
chafed or spongy fuel hose, loose connections, loose or missing fuel hose 
clamps, damaged fuel tank, or defective fuel shut-off valve.
