    introduction Attention: Read through the complete manual prior to the initial use of your Pressure washer Using the Operator’s manual The operating manual is an important part of your pressure washer and  should be read thoroughly before initial use, and referred to often to make  sure adequate safety and service concerns are being addressed. Reading the owner’s manual thoroughly will help avoid any personal injury  or damage to your pump. By knowing how best to operate this machine  you will be better positioned to show others who may also operate the  unit. You can refer back to the manual at any time to help troubleshoot any  specific operating functions, so store it with the machine at all times.
