IMPORTANT: READ THIS MANUAL CAREFULLY BEFORE INSTALLING. .
OPERATING OR SERVICING THIS EQUIPMENT.
OPERATING AND SAFETY PRECAUTIONS RECOMMENDED LUBRICANTS
l Keep hands and clothing away from rotating end of tool.
l Wear suitable eye protection while operating tool.
l Disconnect air supply from tool before removing/installing bit
or performing other maintenance procedures.
ROUTINE LUBRICATION REQUIREMENTS
Lackoforan excessive amount of lubrication will affect the perfor-
mance and life of this tool. Use only recommended lubricants at
below time intervals:
EVERY 8 HOURS OF TOOL OPERATION - Fill air line lubricator
reservoir of recommended F.R.L. with spindle oil (29665).
EVERY 160 HOURS OF TOOL OPERATION - Inject NLGI #l
“EP” grease (33153), 1 to 2 strokes, thru grease fitting in gear
housing. NOTE: Spindle must be extended from outer sleeve suf-
ficiently to expose grease fitting in gear housing. Gearing should
contain approximately 1/4 oz. (7 g) of grease per set of gears.
AIR SUPPLY REQUIREMENTS
Formaximum operating efficiency, the following air supply specifi-
cations should be maintained to this air tool:
l AIR PRESSURE - 90 PSIG (6 bar)
l AIR FILTRATION - 50 micron
. LUBRICATED AIR SUPPLY
l HOSE SIZE - 3/8” (10 mm) I.D.
An AR0® model C28231-810 air line FILTER/REGULATOR/LU-
BRICATOR (F.R.L.) is recommended to maintain the above air
supply specifications.
MOUNTING
The nose end of the outer sleeve (40) is provided with 2-1/2” - 16
L.H. threads (remove thread guard [45] for use) and a 2-1/2” x
1-1/4” long pilot diameter for fixture mounting. Foot and flange
type mounting brackets are available for tool mounting.
After disassembly iscomplete, all parts, except sealed or shielded
bearings, should be washed with solvent. To relubricate parts, or
for routine lubrication, use the following recommended lubricants:
Where Used ARO Part # Description

SET-UP PROCEDURE
WARNING: Keep clear of rotating end of unit with hands and/or
clothing. Keep fingers/hands from being pinched between hous-
ing orvalves and adjustment screws and/or trip bracket.

Loosen two screws (11) and remove cover (1).
Allow a minimum distance of 1/4” between the drill point of the
unit and the workpiece (this is necessary for the air motor to
start and reach free speed before the drill point touches the
workpiece).
Determine the TOTAL STROKE LENGTH the drill must travel
to perform the drilling operation - see illustration below.
Loosen jam nut (8) and turn adjustment screw “A” so the dis-
tance between the end of the screw and the stud (28) equals
the Total Stroke Length.
lighten jam nut (8).
Loosen jam nut (8) and turn adjustment screw”B” so the dis-
tance between the end of the screw and the button bleed
valve (27) is slightly GREATER than the distance set for ad-
justment screw “A”.
Start and let unit advance until the adjustment screw “A
makes contact with the stud (28).
Carefully, and beaware that the unit isgoing to retract, turn the
adjustment screw “B” until it depresses the button bleed valve
(27) enough to cause the unit to retract.
Tighten jam nut (8).

FEEDRATECONTROLVALVES
l Turnvalve(25), marked“R” an tap of housing,approximately1-1/2
turns counterclockwise (open).
l Turn the other valve (25), marked “F” on top of housing, clock-
wise until closed (do not tighten to snugly).
l Startunit and slowly turn valve (25) marked“F” counterclockwise
(open) until the desired forward rote of feed is reached.
l Afinal adjustmentof the rateof return(retract) can be madewith
the valve (25) marked “R” on housing.
MANUALOPERATION
l Install button bleedvalve (27) in eitherthe “F” port located at top
of valve housing orthe “F” port located at the rear of valve hous-
ing. NOTE:Unused port must be plugged with pipe plug (26).
l Depressbuttonbleedvalve(27) marked“F” onvalvehousing.The
unit will start in the forward (advancing) mode and continue to
feed forward until the adjusting screw “B” has depressedbleed
valve (27) marked “R” to retract the unit. Seeset-up procedure.
l A manual emergencyretract button bleed valve (27) can be in-
stalled in “R” port at top of valve housing if desired. This valve
can beusedto immediately retractthe unit in case of misaligned
part or other emergency.Valve not furnished.
REMOTEOPERATION
Install a pressurebleedvalve-ARO part number9600 - in valve
port marked “F” at either the top or rear of valve housing.
Connect pressurebleed valve - using 1/8” i.d. tubing - to a re-
moteoperatedvalve which, when actuated,feeds air pressureto
the pressurebleed valve. Pressurebleed valve will bleed the air
from “F” port of valve housing causing spool valve in housing to
shift to the forward feed position,thus starting-theforward stroke
of the unit.
Install a pressurebleedvalve-ARO part number9600 - in valve
port marked “R” at the top of the valve housing and connect -
using 1/8” i.d. tubing - to a remote MANUALLYoperated valve.
Thisvalve is used as on emergencyretractin case of a part mis-
alignment or such only asthe unit, when properlyset-up and ap-
plied,will automatically retractand returnto thestart position.See
set-up procedure.
Referto page 9 for plumbing and schematic diagrams.
SPECIALNOTE:Theair inlet and remoteportsof valvehousinghave
tapered pipe threads and should not require the use of thread
sealants,such OSsealant tape or pipe joint compounds, Thread
sealants, when used improperly, can contaminate air passages
and cause valve or unit to malfunction.

Your ARO self-feed tool is designed to deliver specific horsepower and thrust to achieve high rates of work. To assure the unit wilt develope this power, care must be token that
the power air inlet system Is correctly sized to permit the proper rate of air flow. Shown is o system for o single tool that will supply correct delivery. IMPORTANT - the tool is power
rated when 90 p.s.i. is present AT THE TOOL DURING OPERATION.
Shown below is the some system in schematic form.

(Y157-44). .
Measuredistance from drill paint to work piece - distance “Y”.
Distance“X” between hydraulic check plunger and trip bracket l
must be lessthan distance “Y” to preventdamage to drill point
when it approaches the work piece.
Loosenthe Capscrews (Yl57-44) and position hydraulic check
to obtain correct setting for distance “X”.
Tighten cap screws (Y157-44)securely before operating unit.
Increasethe air flow thru the feed control valve marked “F” by l
Openingtwo (2) full turnsfrom closedposition.Thiswill allow drill

Start drill unit and the drill will advance at a rapid rate until the
trip bracket contacts plunger of hydraulic check.
Slowly rotatethe hydraulic feed rate counterclockwise for faster
feed rate or clockwise for slower feed rate.

TO START - Depress the remote button momentarily. The unit will advance the drill to a pre-set depth and automatically retract to the initial position whereupon the Unit Will stop.
EMERGENCYRETRACT- Depress the emergency button momentarily. The signal to the Unit will shift the built-in pressure operated valve, commanding the unlitto retract immediately
to the lnitial position whereupon the unit will stop.
NOTE: MANUAL START and EMERGENCY RETRACT buttons on the tool ore fully operational even when remote control is used. The manually operated buttons con be used when

REMOTEOPERATION
Remote operation is achieved by connecting a 4-way valve to the remote start and retract ports, as shown above. This valve supplies power directly to the feed piston In the tool.
TO START - Move lever forward. The Unit will advance to o preset depth (adjustment screw contacts stud on valve housing),
TO RETRACT - Move lever rearward (back). The unit will retract to the initial position.
EMERGENCY RETRACT-The unit will retract at any time the lever is moved to the rearward (back) position. The motor runs continuously as long as air pressure is present at the
air inlet to the tool. A shut-off valve should be instolled In the air inlet line to completely shut the tool off in case of an emergency.
Shown below is the some system in schematic form.
