Yes, but with strict requirements. Using the wrong cord is a common cause of startup failures and blown fuses.
- The extension cord plug and socket must be of watertight construction.
- It must be heavy-duty to handle the amp draw. The unit is rated 14.5A.
- A cord that's too long or thin can cause a voltage drop, leading to loss of power, overheating, and the thermal sensor tripping.
Best practice: Try to use the machine without an extension cord. Plug it directly into a GFCI-protected outlet. If you must use a cord, ensure it's as short as possible and rated for outdoor/industrial use.
If you're having problems: If the machine refuses to start or the fuse blows, the first troubleshooting step is to try the unit without the extension cord. A defective or underrated cord is a listed possible cause.
Heads up: Never carry the machine by the cord or yank the cord to unplug it. Keep the cord away from heat, oil, sharp edges, and the spray path.
