Operations
Components
1. VACUUM GAUGE
This gauge indicates in inches of mercury how
much vacuum the system is producing at any given
time.
2. SOLUTION PRESSURE GAUGE
This gauge registers the amount of pressure in the
system.
3. WASTE PUMPOUT
This switch actuates the optional waste pumpout.
4. SOLUTION TEMP GAUGE
This gauge measures the temperature of the
cleaning solution exiting the machine.
5. SOLUTION PUMP SWITCH
This switch serves to energize the magnetic clutch,
to turn the pump on and off. Turn clockwise to
activate the pump and counter clockwise for de-
activating the pump.
6. CHOKE
The choke is for restricting air to the carburetor,
this enriches the fuel mixture. The primary
purpose is for starting in cold temperatures. When
the cable is pulled out air is restricted, when
pushed in the engine is in run position.
Do NOT run engine with choke pulled out.
7. IGNITION SWITCH
The ignition switch controls the power for the
machine. To turn the machine on, turn solution
pump switch counterclockwise to override and
hold. Turn key clockwise until engine starts and
release. Wait 5 seconds then release override
switch. To stop engine rotate key to OFF position.
8. THROTTLE
The throttle is used to set the speed of the engine
(rpm). The engine speed (rpm) may be increased
by releasing the collar lock, pushing in the red
button on the end of the handle, and pulling the
handle straight out. Engine speed may be changed
in smaller increments by rotating the throttle handle
clockwise or counter-clockwise. The collar lock can
be tightened to prevent the throttle from slipping
and changing the engine speed.
9. HOUR METER
The hour meter records the number of hours the
unit has run. This serves as a time recorder for
servicing the machine.
10. CIRCUIT BREAKERS
These serve to protect the circuits from electrical
spikes and over loads and protects wires from
damage and fire.
11. TEMPERATURE BALANCE ORIFICE
The temperature balance orifice helps to balance
and stabilize the solution temperature within the
system.
12. SOLUTION PRESSURE REGULATOR
The pressure regulator sets the pressure of the
solution system. This spring loaded valve can be
adjusted up or down. The pressure is increased by
turning the valve clockwise, or reduced by turning
the valve counter clockwise. (This valve must be
maintained in accordance with this manuals main-
tenance table.)
13. LUBRICATION CUP
The lubrication cup allows lubricant spray to reach
the vacuum blower.
