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.
AIRf~IH§::IErUP
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.
LtJ~lil~I,Oftf··
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 25 SCFM.
RECOMMENDED HOSE SIZE: 5/16" nominal inside diameter.
oalJ\jMlNt PROPER AIR PRESSURES
AVK's power installation tools have been designed to operate at the listed "Dynamic" P. S.1.ratings at the air inlet of the tool. Even
though the in-line pressure gage may show the proper pressure, the use of long hoses, quick-disconnects and other couplers
between the gage and the tool can adversely affect the tool's performance. A simple test, so you may correlate our required P. S.1.
setting with your set-up is:
1. Connect a 1/4" short pipe nipple into the tool's air inlet.
2. Screw a 1/4" pipe tee onto the pipe nipple and put an air gage into the upright leg of the pipe tee.
3. Connect the air supply to the pipe tee using the actual hose, fittings, couplers or connectors that will be used.
4. Now, check the P.S.1.on the test gage at the air tool inlet with the tool running. Adjust, as necessary, the air pressure regulator
so that the P.S.1.required is shown on the test gage. Note the reading on the in-line pressure gage. It will probably read a higher
P. S.1.than the gage at the tool. The figure on the in-line gage is the "Adjusted Dynamic P.S.I." Use this figure when using the tool
in that location with that hose set-up.
5. Remove tee, nipple and gage, connect air supply directly to tool and begin production.
Test dynamic air pressure readings at the
location where the tool is to be operated*
(Instructions, fig. 3)
2
Adjust the in-line air pressure regulator so that dynamic
pressure is in accordance with AVK's power tool specs
at the air tool inlet.

It is necessary to use the appropriate air pressure and RPM tool to set a particular insert. Here's 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. (i.e. 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.

NOTE: 1. USE LOWER LISTED AI R PRESSURE WHEN INSTALLATION IS IN LOWER PART OF GRIP RANGE AND HIGHER LISTED
AIR PRESSURE IN HIGHER PART OF GRIP RANGE.
2. CONTACT FACTORY FOR PSI SETTINGS NOT LISTED.
*3. LUBRICATE MANDREL OFTEN-EVERY 2 OR 3 INSERTS.
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.
3
4. After tool stalls, reverse the
tool by depressing the
"bottom" of the trigger.
Removal of the tool completes
the installation.

Power ranges have been carefully selected to assure proper insert
installation. One RPM tool may be used to set various thread size
inserts as shown in the PSI and RPM chart. Be sure to match the RPM of
the tool to the insert thread size, and insert material.
Complete tool adaption kit (CTA) is that portion of the tool that is
screwed onto the air motor to make a AVK insert tool. (Left hand thread)
Thread adaption kit, (TAK) is the portion of the CTA that is disengaged
by activation of the "quick release mechanism". Note the following
illustrations.

Below are some guidelines for solutions to common setting and tooling problems. By following these steps you should be
able to get back into production as quickly as possible if a problem arises:
SCREWS BREAK FREQUENTLY
1. Too much air line pressure. Check the air pressure specs
for the thread size you are placing. Adjust downward
accordingly.
2. Make sure operator is holding the tool at a 90° angle to
the adequate supply of air to the tool.
TOOL STALLS BEFORE FULLY
PLACING THE INSERT
1. Be sure there is a bearing assembly in the tool. Check to
be sure it is not worn out, and that it is assembled correctly.
(see pg. 4 or 5). Clean in solvent, blow dry and lubricate with
recommended grease. (See tool maintenance section of this
manual.)
2. Check for quick disconnect fittings with holes of 1/4" or
3/16". These may be too small to allow the necessary
VOLUME into the tool. This is especially critical with the 5/16,
3/8 and %thread size.
3. Be sure the hose 1.0. is 5/16".
4. Not enough air line pressure. Check the air pressure
specs for the thread size you are placing. Adjust upward
accord ingly.
5. Check the condition of the drive screw. Replace, if worn
using high quality socket head cap screws.
6. Check to see if other air tools are being used that are
starving the insert installation tool.
TOOL WILL NOT START/RUN
1. With air system connected, quickly change from forward to
reverse several times.
2. Check your air line and air pressure to assure there is an
work piece, and not "tilting" it over to one side.
3. Remove the complete tool adaptation kit. Manually rotate
rotate the square drive shaft. Connect air to tool and depress
trigger.
4. Evaluate airline set-up portion of this manual.
5. If there is an air motor failure, follow instructions in
maintenance section of this manual.
AIR MOTOR RUNS,
PLACING SCREW DOESN'T
Make sure hex drive is engaged into the socket head cap
screw. Check to see if screw is broken or if the head is rounded
out. Check also, if the hex drive itself has been rounded off.
Replace defective parts as may be required to assure proper
installation.
*CALL AVK FOR ADDITIONAL TROUBLE
SHOOTING SUGGESTIONS
I. Inadequate compressor capacity.
4. Be sure hose and quick disconnect fittings have 5/16" 1.0.
2. Improper pipe sizes (1.0. too restrictive).
3. Restrictions caused by fittings with 1.0.'s too small. See
Note 3 above.
If recommended pressures cannot be obtained, the supply system should be checked. Some things to look for are:
5. Shut-off valves. It is best to use stop cock type, which
lessen restrictions.
6. Improper coupler and quick disconnect. Use only those with
good flow characteristics and assure that they mate
correctly.
7. Filter-regulator-lubricator should be compatible, properly
sized and maintained.
8. Clogged filter.

TOOL MAINTENANCE
THRUST BEARING
It is essential that the thrust bearing be lubricated with Luoriplate* #930-AA or equivalent. The thrust bearing and mandrel
(socket head cap screws - see pages 4 &5) are located in the nose cone of the tool. Lubricate as needed, bearing
should not run dry. For further details see sections entitled Thread change-over and Disassembly for service (Pages 9-12).
Remove the nose cone &proceed as follows:
Remove the
bearing and
socket head
cap screw.
Separate the
bearing from the
races and lubricate.
Work grease into bearing.
Replace screw if
worn. Use only high
quality grade 8 screws.
See pgs. 4 &5 for lengths.
Reassemble.

DISASSEMBLY FOR AIR MOTOR SERVICE
If a problem develops with the air motor, simply disassemble it as shown below and either send the air motor to an ARO service facility
or obtain parts from them for repair.
U sing a 1 7/16" wrench on the
two flats on the housing,
unscrew turning clockwise
(LH thread), unscrew from
tool, and remove the spring
and square drive.
ARO SERVICE FACILITIES
Keep these parts separate
from the air motor. Send
the air motor only to the
nearest ARO repair center.
To send a tool motor for repair or to obtain parts, call the appropriate number below. You will be referred to the nearest service
facility.

PREVENTIVE MA~~TENANCE
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.
LUBRICA nON 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 fittings which can be serviced by ARO's Grease Gun #7464-1. Grease 33153 (5
lb. can) for gears and bearings; "0"Ring Lubricant 36460(4oz. tube) for lubrication and installation of "0"Rings.
CAUTION: An excessive amount of lubricant in a tbol will affect the speed and power. Each set of planetary gearing should
contain approximately 1/8 ounce of grease.
FLUSH TOOL with a solution of three parts cleaning solvent and one part light oil after each 40 hours of operation. After
flushing, apply a small amount of Spindle Oil in air inlet and run free for one minute to insure proper lubrication.
IF LINE OILER is not used, apply a small amount of Spindle Oil in air inlet of tool and run free for one minute to insure proper
lubrication; after each 8 hours of operation.
LUBRICATE DRIVE SCREW. In some applications it may be advisable to dip the first one or two threads of the mandrel into a
light oil after several installations to minimize wear.
