4-3: Operating Instructions
To help achieve a high psi rating for high pressure washing, HydraMaster has added a
chemical pump shutoff valve into the Boxxer 318HP’s pump system. The shutoff valve
can be accessed from the side of the machine (see Figure 4-3).
Operating the Boxxer 318HP at pressure levels higher than 600 psi with the
chemical pump shutoff valve turned on can result in serious component damage.
Before adjusting the pressure for high pressure washing operations, turn off the
chemical pump shutoff valve by turning the handle, shown in Figure 4-3, so that
it is perpendicular with the pump. See page 4-6 for details.
Note that there is a “CHEMICAL PUMP” valve located on the dash assembly
(see Figure 4-1). This is not to be confused with the chemical pump shutoff valve
shown in Figure 4-3.
