Maintenance & Repair
37
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 & 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.
