**NOTE ON UNLOADERS**
Unloader valves are one of the most important safety devices on a pressure washer system. It is recommended that an experienced mechanic installs the unloader and sets the operating and spike pressure properly with a pressure gauge.
Failure to install and set the unloader properly could result in a very dangerous situation causing severe damage to the pump and possibly the operator.
