How
to
Adjust
the
Working
Pressure
Correctly
Note: It’s
not
necessary
to
start
the
vehicle
.
The
working
pressure
of
the
pressure
regulator
has
been
set
as
1~1
.
5
bar
before
delivery, to
ensure
that
the
car
reservoir
tank
will
not
deform
while
changing
the
fluid, thereby
guaranteeing
the
sealing
performance
of
the
secondary
sealing
ring. In
addition, it
allows
you
to
exhaust
the
air
or
change
the
liquid
at
a
relatively
low
working
pressure
by
adjusting
the
pressure
and
the
switch. Under
the
special
circumstances, while
operating
at
a
relatively
high
working
pressure
,
the
pressure
is
not
supposed
to
be
too
high,
which
may
damage
the
clutch
master
cylinder
of
the
braking
system.
Operation
Instructions
Low-pressure
Sealing Performance
Test
By
using
this
(smart)brake
fluid
replacement
machine, you
can
exhaust
the
air
and
fill
the
fluid
for
your
brake. You
can
also
perform
low
pressure
detection
on
the
hydraulic
brake.
The
device
can
be
connected
to
the
car
reservoir
tank
through
an
adapter. Please
close
all
the
air
valves
before
the
connection. The
air
in
the
braking
system
is
pressurized
by
the
working
pressure
of
the
device (to
the
pressure
required
by
the
specific
car
model). Please
check
the
master
cylinder
and
the
braking
pipelines
in
case
there
is
any
leakage. If
the
brake
fluid
overflows, it
means
the
braking
system
is
not
completely
sealed
.
Lift
the
car
to
a
proper
height
to
make
the
driving
wheels
off
the
ground.
Connect
the
four
oil
tanks
of
the
device
to
the
car
clutch
slave
cylinder, and
loosen
the
exhaust
screws
to
ensure
there
is
oil
flowing
out.
Pour
2
liters
of
new
brake
fluid
into
the
fill
port
of
the
device, and
connect
the
adapter
that
matches
the
car
model
with
the
port
of
the
brake
fluid
reservoir
of
the
car
master
cylinder.
Connect
the
device
to
a
12V
car
battery
and
turn
on
the
power
switch
.
Press
the “START” button
to
change
the
brake
fluid.
When
changing
the
fluid, please
pay
attention
to
the
port
of
brake
fluid
reservoir, if
the
process
is
too
slow, press
the “Accelerate”
button
and
if
it’s
too
fast, press
the
“Decelerate”
button
to
slow
it
down
.
After
the
oil
change
finishes, the
used
oil
in
the
tank
of
the
equipment
must
be
completely
drained. If
it’s
not
emptied, the
vacuum
pump
will
be
damaged
and
the
oil
change
process
will
fail
.
Reminder
:
Please
check
each
connection
parts
when
changing
the
fluid
to
see
if
there
is
oil
leakage
and
whether
the
connecting
hose
is
damaged
.
Please
keep
the
oil
fill
port
clean
.
