Important Precautions

• Always read carefully and understand instruc-

tions prior to using this equipment

• Wear gloves and approved safety goggles while

using this product.

• Consult and follow the vehicle manufacturer’s

recommended procedures.

• Do not use this unit with ﬂammable liquids or

with ﬂuids at temperatures above 175° Fahren-

heit (80° Celsius).

• Properly dispose of old ﬂuids.

• Do not attempt to pressurize the bleeder/evacu-

ator. It is designed for vacuum use only.

• This unit is equipped with an automatic shut-off

device that will prevent ﬂuid from entering the

compressed air stream and ejecting through the

exhaust. However, if the unit is continuously op-

erated when the reservoir is full, residual pres-

sure will allow the reservoir to completely ﬁll with

ﬂuid, creating the potential for spillage when the

lid is removed. To prevent this situation, empty

or turn the unit off prior to ﬁlling the reservoir

completely full.

The screws included in the Base Kit 822701 are

provided to secure the base to a work surface.

Do not use the screws to attach the base to the

reservoir.

Principal of Operation

This unit is designed for use as a ﬂuid evacua-

tor. It utilizes compressed air between 60 psi (4.1

bar)and 150 psi (10.3 bar), and a venturi system,

to build vacuum in the reservoir. By attaching the

proper accessory to the coupler located on the

top of the unit, the vacuum can be used to evacu-

ate a variety of ﬂuids from reservoirs including the

master cylinder or those for power steering ﬂuid or

engine coolant.

Instructions for Using the

Mini-Fluid Evacuator

1. Connect clean, regulated (60 psi (4.1 bar) to 150

psi (10.3 bar)) compressed air to the male quick

disconnect nipple attached to the swivel air

inlet, located on one end of the vacuum bleeder

handle.

2. Connect the appropriate end of the evac tube

assembly to the female quick disconnect cou-

pler located on top of the evacuator.

3. Insert the other end of the evac tube assembly

into the ﬂuid reservoir, and push the evacua-

tor throttle forward to start the vacuum (allow a

few seconds for vacuum to build in the bleeder

reservoir before suction occurs).

4. Once all ﬂuid is removed, turn off the evacuator.
