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 variety 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 applica-
tion. A gauge is installed to indicate the pressure
in the reservoir, 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 acces-
sories it can safely be used to pressure bleed hy-
draulic brake or clutch systems, or refill or top-off
sealed automatic transmissions.
Precautions
This equipment is designed for servicing a variety
of vehicles in a safe, convenient manner. How-
ever, 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
manufacturer’s recommended procedures when
servicing each unique vehicle.
The use of this equipment is simple and straight-
forward 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 ser-
vice functions 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 authorized 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
recommended 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
reservoir. 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
accessory to the quick-connect coupler ex-
tending 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 de-
signed to open and maintain maximum pres-
sure between 17 and 23 psi (1.2 and 1.6 bar).
Continual operation of the pump is not re-
quired 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 pres-
sure exceeds 25 psi, immediately discontinue
use and send the unit to an authorized service
center for repair or replacement.
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
intended 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.
