This equipment is designed and intended for use as a
means to dispense fluid. It utilizes a manual pressure
pump to build pressure in the reservoir. The pressure
forces fluid to dispense out of the reservoir through a
fluid pickup tube. The output of the fluid pickup tube
is connected to a quick-change coupler, to which a va-
riety of accessories can be attached to control or direct
the flow of fluid according to the intended application.
The equipment should never be operated above a
safe level of pressure depending on the application. A
gauge is installed to indicate the pressure in the reser-
voir, and should be observed regularly to ensure the
pressure remains at or below what is recommended
for the application.
Applications
This equipment is intended for filling reservoirs with
fluids such as engine coolant, motor oil, or wiper,
automatic transmission, brake or power steering fluid.
However, with the proper accessories it can safely
be used to pressure bleed hydraulic brake or clutch
systems, or refill or top-off sealed automatic transmis-
sions.
Precautions
This equipment is designed for servicing a variety
of vehicles in a safe, convenient manner. However,
differences in vehicle makes and models may make it
impossible to use this equipment as it is intended. Do
not attempt to force the use of this equipment on an
application for which it is not designed to perform.
The procedures documented in this manual are to
serve as guidelines for the use of this equipment. In
addition to these guidelines, always follow the manu-
facturer’s recommended procedures when servicing
each unique vehicle.
The use of this equipment is simple and straightfor-
ward if you follow the instructions. However, always
keep in mind that you are working with a system that
may be under pressure, with fluid that is just waiting
to be expelled. When operating this equipment,
use common sense, and always stop to think before
disconnecting a hose or other component.
• This equipment is intended only for professional use
by personnel trained in performing the service func-
tions for which it is has been designed.
• Read carefully and understand all instructions prior
to using this equipment.
• Always wear eye protection and proper clothing
when operating this equipment
• Do not attempt to modify the pressure relief valve
to alter its performance. If pressure in the reservoir
ever exceeds 23 psi (1.6 bar), return it to an autho-
rized service center for repair or replacement.
• Some fluids, including brake fluid, are corrosive,
and proper care should be taken to protect painted
surfaces and skin from exposure.
• Do not use this equipment with gasoline or other
flammable liquids, or with fluids at temperatures
above 175° Fahrenheit (80° Celsius).
• Consult and follow the vehicle manufacturer’s rec-
ommended procedure when using this equipment
to perform automotive service.
PRINCIPAL OF OPERATION

Form 801193 Page Number - 5
Fluid Dispensing
1. Unscrew the lid w/ pump from the reservoir, and
fill to desired level with clean fluid.
Note:There are two scales of volume on the res-
ervoir. One scale indicates the volume when the
lid w/ pump is removed and one when the lid w/
pump is installed. Be sure to note the appropriate
scale.
CAUTION: If fluid is added above the MAX FILL line,
the reservoir will overflow when the lid w/ pump is
installed.
2. Reinstall the lid w/ pump onto the reservoir.
3. Connect the fluid dispensing hose or other acces-
sory to the quick-connect coupler extending from
the reservoir. Ensure the coupler sleeve snaps
forward to lock the
connection.
Note: Depending on the application, the shutoff
valve installed in the fluid dispensing hose may be
left open or closed. If left open, fluid will begin to
flow as soon as the pump is operated. If closed,
pressure will build in the reservoir as indicated on
the gauge.
4. While observing the pressure gauge, operate the
pump to build pressure in the reservoir to the
desired level, or until the desired amount of fluid
has been dispensed.
Note: A built-in pressure relief valve is designed to
open and maintain maximum pressure between
17 and 23 psi (1.2 and 1.6 bar).
Continual operation of the pump is not required
to maintain fluid flow. Fluid will continue to flow
as long as there is pressure in the reservoir and the
shutoff valve is open.
WARNING: Do not exceed 25 psi (1.7 bar) pressure
in the reservoir. The relief valve should prevent
this, but if it fails and the pressure exceeds 25 psi,
immediately discontinue use and send the unit to
an authorized service center for repair or replace-
ment.
5. Once the proper amount of fluid has been dis-
pensed, close the shutoff valve and bleed off the
pressure by tilting the pressure relief knob located
on the lid.
6. Depending on the type of fluid and future intend-
ed use, you may store the remaining fluid from the
reservoir. Otherwise empty the reservoir, clean it
with denatured alcohol or a common household
cleaner, and store it properly.
