2.8 Handheld Pressure Washer
A hydraulic powered pressure washer is mounted
to the chassis below the charge water pump. It
provides up to 4000 psi (276 BAR) to the hand-
held spray gun. The pressure hose and spray gun
connect to a high pressure disconnect tting on
the pump and are stored in the tool box when
the handheld pressure washer is not being used.
The pressure washer is powered by the truck hy-
draulic system. A manually operated hydraulic
ow control valve supplies pressurized hydraulic
uid to the hydraulic motor that powers the pump.
The hydraulic ow control valve is equipped with
colored rings that indicate the valve setting for
reference. Another ball valve on the water line
turns the water supply to the pressure pump on
or o. Pressurized water from the clean water
tank is provided to the pump by the charge water
system. Always make sure to close the hydraulic
pressure and water ball valves whenever the pump
is not being used.
Use the following procedures to activate and shut-
down the handheld pressure washer.
Activating the pressure washer:
1. Make sure the truck is parked on level ground
with the parking brake set and the engine at
idle.
2. Verify that the pressure gauge on the pump
indicates 0 pressure, then attach the pressure
hose and gun to the quick disconnect tting.
3. Make sure the truck is in Operate Mode.
• Automatic Transmission - PTO and Mode
switches in the console are ON and the
transmission is in 4/4 Lockup.
• Manual Transmission - PTO switch in the
console is ON and transmission shifted to
the correct operating gear.
4. Raise the engine speed to 1000 RPM.
