Frequently Asked Questions
Does It Include a Wheel Kit and Handles for Transport?
No, it does not include a wheel kit and handles; the package lists remote start fob, battery charger, oil, funnel, tool kit, and manual. The buyer should purchase the wheel kit and handles separately for transport.
Can It Run a Whole-House Panel via a Transfer Switch?
Like a reliable bridge, yes. It can power a whole-house panel via a properly installed transfer switch, supplying up to 9500 running watts (gas) with safety features and correct load management to avoid overloads and CO risks.
What Maintenance Schedule Is Recommended for Long-Term Use?
A regular maintenance schedule is recommended: change oil and filter every 50–100 hours, replace air filter every 100 hours, spark plug annually, fuel stabilizer for storage, inspect fuel lines and battery monthly, and perform full service annually.
Is It CARB Compliant for Use in All U.S. States?
No; it is not CARB-compliant for use in all U.S. states. Featuring up to 12 hours runtime on a 6.6-gallon tank evokes extended duty, but buyers should verify California/other state CARB requirements before purchase.
Are Replacement Parts and Accessories Readily Available?
Yes; replacement parts and accessories are readily available through Westinghouse’s nationwide customer service network, authorized dealers, and common retailers, ensuring warranty support, factory-tested components, remote-start key fobs, batteries, and routine maintenance items.
