PRINCIPLE OF OPERATION
This equipment is designed and intended for use as
an accessory to dispense or evacuate fluids using a
Mityvac hand pressure/vacuum pump (sold sepa-
rately) . The hand pump is utilized to build pressure
or vacuum in the fluid transfer bottle . Pressure can
be used to dispense fluid out of the bottle for the
purpose of bleeding hydraulic brake or clutch sys-
tems, or for filling or topping-off various automotive
reservoirs . Vacuum can be used to bleed hydraulic
brake or clutch systems, or to evacuate fluids from
various automotive reservoirs .
Fluid is added or emptied from the fluid transfer
bottle through the top by removing the threaded
cap . Pressure or vacuum is applied to the bottle via
a hand pump connected to the inlet hose extend-
ing from a nipple near the top of the bottle . Fluid
is dispensed or evacuated through the fluid hose
connected to a nipple extending from the bottom
of the fluid transfer bottle . A fluid wand is included
for connection to the output of the fluid hose via
a quick-change coupler . It can be used to direct
the flow of fluid into a reservoir or to reach into a
reservoir to evacuate fluid out . The quick-change
coupler has an automatic shut-off valve that will
stop fluid flow when the wand or other accessory is
not connected . A ball valve is installed in the fluid
hose to shut-off or control the flow of fluid to or
from the fluid transfer bottle .
Additional accessories including master cylinder
adapters for pressure bleeding, and ATF adapters
for topping-off sealed transmissions, may be includ-
ed or are available for separate purchase, and will
greatly expand the applications of this equipment .
PRECAUTIONS
This equipment is designed for servicing a variety of
vehicles in a safe, convenient manner . However, dif-
ferences in vehicle models may make it impossible
to use this equipment as 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 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 should never be operated above a
safe level of pressure, depending on the
application . When pressurizing the fluid transfer
bottle, always use a hand pump with a pressure
gauge installed . When operating the pump, observe
the gauge to ensure the pressure in the bottle re-
mains at or below the recommended pressure for the
application . Never pressurize the fluid transfer bottle
above 20 psi/1 .4 bar/140 kPa .

8’ (2 .5 m) long clear inlet hose (3) to the barb
located on the side of the fluid transfer bottle
(5) .
2 . Using a second finger clamp (4), secure the 5’
(1 .5 m) long hose, valve and quick-change cou-
pler (6) assembly to the barb extending from
the bottom of the fluid transfer bottle (5) .
3 . Ensure the cap seal (2) is installed in the cap,
and thread the cap w/ chain assembly (1) onto
the top of the fluid transfer bottle .
