INTRODUCTION
Read
manual before
operating
tool.
You
now own
the finest
insert
installation
tool on
the market
today.
These
durable
tools provide
many
years of
trouble
free
operation
if
you
will
simply follow
the instructions
in
this manual.
Prior
to use,
certain
checks
must be made.
This tool
requires
the proper
air
line setup,
lubrication,
and
air pressure
to set
the
desired
inserts.
AIR
LINE
SET UP
Every
ARO
Air Tool is
designed
and
built to
yield the
longest possible useful
life,
with
a
minimum
amount
of
servicing.
Since
an air
tool
is
a
precision
machine
whose
working
parts
mate
with
close
tolerances,
it should
receive the
same reasonable care
as any
other
machine
tool.
Here
are
a few
simple
practices
that will
keep
your
ARO
Air Tool
in
top
operating
condition.
KEEP
AIR
SUPPLY
CLEAN.
All
compressed
air carries
varying
amounts
of
dust,
scale,
moisture
and
other
foreign
matter
that
should
be removed
by
proper
filtering.
Failure
to
keep
air
supply
clean
will
result in
excessive
wear
on working
parts.
Therefore.
we
recommend
the
installation
of an
air line
filter. If
your tool
is
equipped
with
a
built-in
air
strainer, remove
and
clean the
strainer
periodically.
Always blowout
the
air
hose
before
attaching
to tool.
LUBRICATION
USE
AIR LINE
LUBRICATOR.
Air
tool motors
operate
at
extremely
high speeds.
and must
have proper
oil
lubrication.
An
air line
lubricator
should
be
installed
and oil
supply properly
regulated.
Your
ARO Distributor
can furnish
the correct
combination
air
line
filter
and
oiler.
Some
units
can
service up
to
three tools
simultaneously. As a
further precaution,
put
a
few drops
of light
oil in
air
inlet
of
tool before attaching
tool
to
air line for
the
first
time
RECOMMENDED
LUBRICANTS:
Spindle
Oil
29665
(I
qt.
container)
for oiler
and air
inlet.
FILTERED
AND
OILED
AIR will
allow
the tool
to
operate
more
efficiently
and
yield
a
longer
life
to
operating
parts
and
mechanisms.
A line filter
capable
of filtering
particles
larger
than
50
microns
should
be
used
with
a
line
oiler.
FILTER-REGULATOR-OILER
combination
(F-R-L)
Model
28231-810
is
recommended
for
use
with
this
Air
Tool. The
capacity
of
the
individual
Filter-Oiler
is
adequate
to
provide
clean
(40 micron),
oiled
and
regulated
air for
the tool
AIR CONSUMPTION:
Approximately

PROPER AIR
DIFFERENT INSERTS
It is necessary to use the
appropriate air pressure
and RPM
tool
to set a
particular insert. Heres how
to insure the proper
set
up:
1.
Identify the
TYPE
of
insert.
(i.e
AH-AL-AK-AO-AT
etc.)
2 Identify the insert
material. (ie.
steel,
brass
etc.)
3
Identify the
thread size. (i.e. #10-32” 1/4-20, M6
etc.)
4
Refer
to
the following table. Find the correct material
&
insert type heading and come down to the PSI
&
RPM line
adjacent
to the
thread size. Use
this
pressure
setting
and
tool
RPM.
PSI
AND
RPM CHART
1.
Place the insert
into the
prepared hole. Insert
tool
mandrel into insert, engaging
the
thread.
Not
recommended
with
A-H Series.
2. For the
A-H Series we
recommend threading
the
tool
mandrel then insert into
hole.
3. Keep the
tool square to
the
work piece
and depress the
“top”
portion of the trigger
until
tool stalls.
4. After tool
stalls,
reverse
the
tool by
depressing
the
“bottom”
of the trigger.
Removal of the
tool
completes
the
installation.

PREVENTIVE
MAINTENANCE
HANDLE
WITH
ORDINARY
CARE.
A
high
proportion
of tool
repairs
can
be
traced
to careless
handling.
In
spite
of their
inherent
strength,
air
tools should
not
be used
as hammers
or
levers,
nor
should
they
be
deliberately
dropped
or
dragged along the
floor.
LUBRICATION
OF
GEARED
TOOLS.
Certain
types
of air
tools
contain
gearing
which
should
be
lubricated
regularly
with
gear
grease.
Most
of these
tools
have
external
hydraulic
