No two Honda pressure washers are alike, and neither are the instruction manuals, but they typically include information on operator safety, hazards, assembly, operation and maintenance. Troubleshooting, proper storage and warranty information are some other subjects covered in the instruction manual.
Honda does not manufacture pressure washers. Honda manufacturs engines that go into pressure washers. Since Honda is a strong brand with its own gravitas, manufacturers often identify Honda engines in the product descriptions for the pressure washers they manufacture, and the Honda label is usually visible on the actual pressure washer.
NorthStar Products and Briggs & Stratton Products are two manufacturers of pressure washers that contain Honda engines. NorthernTool.com and PressureWashersDirect.com are two vendors who sell both brands. Each product info page for a pressure washer with a Honda engine features an owner's manual in PDF.
Briggs & Stratton Honda pressure washers sometimes require assembly of certain parts, such as the handle and the accessory tray, which must be attached before use. The instruction manual addresses this and other pertinent details, such as how to add engine oil, add fuel, lubricate the o-rings, charge the battery and connect the water supply.
NorthStar Products designs several of its pressure washers to be mounted permanently on service vehicles, and instruction manuals for its pressure washers offer steps to do so. An electrical chapter addresses installation of the spark-arrestor, connection and disconnection of the battery, and where to apply safety decals.
