READ THIS MANUAL CAREFULLY BEFORE INSTALLING,
OPERATING OR SERVICING THIS EQUIPMENT.
It is the responsibility of the employer to place this information in the hands of the operator. Keep for future reference.
OPERATING AND SAFETY PRECAUTIONS
AIR SUPPLY REQUIREMENTS
•
Keep hands and clothing away from rotating end of tool and all
moving parts of the tool.
For maximum operating efficiency, the following air supply specifi-
cations should be maintained to this air tool:
•
•
Wear suitable eye protection while operating tool or when
near tool when it is being operated.
Disconnect air and electrical supply from tool before remov-
ing/installing bits or performing other maintenance or service
procedures.
•
•
•
AIR PRESSURE – 90 PSIG (6 bar)
AIR FILTRATION – 50 micron
HOSE SIZE – 5/16” (8 mm) I.D.
An AROR model P29231–110 air line FILTER/REGULATOR plus
100067 gauge is recommended to maintain the above air supply
specifications.
ROUTINE LUBRICATION REQUIREMENTS
When this tool was built, an “O” ring lubricant was applied to all ap-
propriate dynamic seals to insure continued operation. Drive train
components and bearings were also supplied / filled with grease
to insure appropriate life of components. As long as all exterior
seals and wipers are maintained in good working order and all
covers and breather vents are kept in place, it is reasonable to ex-
pect that external debris will not enter the tool. It is also reason-
able to expect that lubricants applied to the tool interior will require
replenishment for at least 5000 hours of normal operation.
Adding spindle oil to the power air inlet of this tool is not
necessary.
RECOMMENDED LUBRICANTS
After disassembly is complete, all parts, except sealed or shielded
bearings, should be washed with solvent. To relubricate parts, or
for routine lubrication, use the following recommended lubricants:

MOUNTING
Mounting clamps 49690 and 46982–1 are available for mounting
of this tool. These items are shown on page 11. Both mounts allow
the clamp to grip the outer sleeve of the tool and feature keyways
for alignment.

INSTALLATION
15
The ARO model FE034A–( ) is NOT supplied with the required
motor starter. The motor starter must conform to the local/national
regulations governing the use of this type of electrical equipment
and must provide motor overload protection. The recommended
overload setting is given on the wiring diagram. The power supply,
motor starter and the motor nameplate ratings must be equiva-
lent.
Connect the motor starter to the motor as shown in the wiring dia-
gram. The minimum wire size should be AWG No. 14, or equiva-
lent, (4107 circular mil) and conform to local/national regulations
governing the use of this type of electrical equipment.
Once the motor is connected, turn on the power supply. If the
spindle fails to rotate or rotates in the wrong direction, de–ener-
gize the motor starter immediately. Turn off the power supply and
recheck the wiring.
MOTOR: The electric motor develops a minimum of .33 horse-
power. The voltage requirements are shown below in the Electri-
cal Connection Diagram.
SET–UP PROCEDURE
WARNING: Keep clear of rotating end of unit with hands and/or
clothing.

SET–UP PROCEDURE
•
•
Assemble hydraulic check to yoke assembly (27).
Measure the distance from the drill point to the work piece –
distance ‘‘Y”.
Distance ‘‘X” between the hydraulic check plunger and stop
pin (38) must be less than distance ‘‘Y” to prevent damage to
the drill point when it approaches the work piece.
Loosen cap screw (28) and position the hydraulic check to ob-
tain the correct setting for distance ‘‘X”.
Tighten cap screw (28) securely before operating unit.
Increase the air flow thru the feed control valve (103) marked
‘‘F” by opening two full turns from the closed position. This will
allow the drill to advance rapidly until the plunger of the hy-
draulic check contacts the stop pin (38).
The hydraulic check feed rate adjustment is located at the
nameplate end. Rotate the extended end until the slot at the
end of the spindle is aligned with the number 15 on the name
plate.
•
•
Start the drill unit and the drill will advance at a rapid rate until
the plunger of the hydraulic check contacts the stop pin (38).
Slowly rotate the extended spindle of the hydraulic check
counter–clockwise toward the number zero on the nameplate
until the drill advances at the desired rate of feed.
•
•
TO CONTROL BREAKTHROUGH
•
•
•
•
Position the hydraulic check so the distance between the
plunger and the stop pin (38)(distance ‘‘X”) is less than the dis-
tance from the drill point to the opposite side of the work piece
(distance ‘‘W”).
Set–up of the self–feed drill unit will be the same as explained
in ‘‘Set–Up Procedure”, page 3.
