2. Verify that the pressure gauge on the pump
indicates 0 pressure, then attach the pressure
hose and gun to the quick disconnect fitting.
3. Make sure the truck is in WORK mode with the
park brake set.
• Automatic Transmission - Dash PTO switch
and CHARGE PUMP switch in the console
are ON and the transmission is in 4/4
Lockup.
• Manual Transmission - Dash PTO switch
and CHARGE PUMP switch in the console
are ON and transmission shifted to the
correct operating gear.
4. Raise the engine speed to 1000 RPM.
5. Make sure the charge water pump is operating,
then open the clean water supply ball valve
near the pump.
6. Close the charge water supply ball valve to the
Jetstream pump. The valve is located under
the manifold of the Jetstream pump. This will
supply additional water pressure and flow to
the pressure washer pump.
7. Slowly turn the knob on the hydraulic flow
control valve counterclockwise until the bot-
tom edge of the knob is even with the green
ring to activate the hydraulic motor and set
proper RPM for the pump.
8. Monitor pressure to the spray gun with the
pressure gauge on the pump and use the
pressure washer manual bypass valve to set
the desired spray gun pressure. Typical pres-
sure settings range from 2000 psi (138 BAR)
to 4000 psi (476 BAR).
Shutting down the pressure washer:
1. Slowly turn the hydraulic flow control valve
clockwise until it seats in the closed position
to deactivate the hydraulic motor and pres-
sure pump.
2. Slowly close the ball valve on the clean water
supply, then briefly pull the trigger on the
spray gun to remove pressure in the hose.
3. Verify 0 pressure on the pressure gauge and
disconnect the pressure hose and gun.
4. Open the charge water supply ball valve to the
Jetstream pump. The valve is located below
the manifold of the Jetstream pump.
5. Reduce engine speed to idle and properly coil
the pressure hose and properly store the hose
and gun in the tool box.
