UPHOLSTERY CLEANING
Upholstery tool, part #78513
1. Set engine speed control to “Low/Upholstery”
setting to minimize excess heat.
2. Use one (1) “80015” spray tip in tool.
SHUTDOWN AND DAILY MAINTENANCE
(LOW PRESSURE)
1. Close chemical metering valve.
2. Allow the unit to run for 2 minutes with the
vacuum hose disconnected to remove moisture.
Spray WD40 (or equivalent) into the vacuum
lubrication cup. This will prevent corrosion due
to moisture.
3. Set engine speed control to idle position and
allow the water temperature to cool down,
unitizing the simulator valve in the open position
to bleed off residual hot water left in the system.
4. Turn off ignition switch.
5. Disconnect all hoses and tools.
6. Drain waste tank.
HIGH PRESSURE (3000 PSI) SYSTEM
OPERATION (OPTIONAL)
The high-pressure water system can produce
water pressures in excess of 3000psi. Water at
these pressures will cause severe injury. DO
NOT direct any discharges at persons. If contact
with a person does occur and penetration of the
skin does seem possible, contact medical
personnel immediately. This machine is to be
used by trained cleaning professionals only.
Ensure all operators are trained in the operation
of this equipment. Keep cleaning area clear of
all persons and objects.
Ensure that proper Personal Protective
Equipment (PPE) is used during the operation of
this equipment. Failure to use proper PPE could
result in injury. Ensure required ventilation
and/or breathing apparatuses are used with a
chemical injection system. Check with your
chemical vendor for proper safety requirements.
OPERATION
The “HP” units are equipped with a water pump and
water delivery system that can support pressure-
washing operations up to 4.5 gallons per minute at
3000 PSI. This system is normally used for high-
pressure washing and hard surface cleaning.
1. Move the temperature selection valve from the
“hot” position to the “warm” position.
2. Allow water temperature to cool to below 160
deg F.
3. Close ball valve located between the chemical
pump and the water pump.
Failure to close this valve will result in severe
damage to the chemical pump diaphragms.
1. Connect hose and either pressure washer gun
or hard surface cleaning tool to high pressure
disconnect.
2. Move the pressure selection valve from the “low
pressure” position to the “high pressure”
position.
3. Adjust high-pressure regulator to desired
operational pressure.
