Maintenance & Repair

31

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.
