DISASSEMBLY/ASSEMBLY Instructions

INSTALLATION

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.

MOTOR: The electric motor develops a minimum of .33 horse- power. The voltage requirements are shown below in the Electri- cal Connection Diagram.

ELECTRICAL CONNECTION DIAGRAM

3 PHASE, 60 Hz

M107

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.

SET–UP PROCEDURE

WARNING: Keep clear of rotating end of unit with hands and/or clothing.

• Shut off air supply to tool.
•	Loosen screw (41), releasing cover (33).
•	Determine the TOTAL STROKE LENGTH the drill must travel
•	to perform the drilling operation.
•	Loosen cap screw (28) securing yoke assembly (27) to quill
	(55) and position yoke assembly on quill approximately 5/8”
	(16 mm) greater distance between control valve (39) and yoke
•	assembly than the distance of the Total Stroke Length.
•	Tighten cap screw (28), securing yoke assembly (27) to quill
•	(55).
•	Loosen nut (29), securing cap screw (30) and turn cap screw
	(30) so the distance between the head of the cap screw (30)
•	and control valve (39) equals the total stroke length.
•	Tighten nut (29), securing cap screw (30).
•	Replace cover (33), securing with screw (41).
•	Attach air supply to tool.

* RECOMMENDED OVERLOAD SETTING.

TO REVERSE ROTATION: INTERCHANGE ANY TWO LEADS.

WARNING: BE SURE THE ELECTRICAL POWER SUPPLY IS OFF BEFORE MAKING ANY ELECTRICAL WIRING CONNEC- TIONS.

WARNING: FAILURE TO PROPERLY GROUND THE MOTOR MAY CAUSE SERIOUS INJURY TO PERSONNEL.

DO NOT BLOCK THE AIR FLOW TO OR FROM THE MOTOR COOLING FAN. DO NOT DAMAGE THE MOTOR FAN COVER. KEEP SMALL OBJECTS CLEAR OF THE OPENINGS IN THE FAN COVER.

FEED RATE CONTROL VALVES

•Turn valve (103), marked ‘‘R” at side of control assembly (93), approximately 1–1/2 turns counter–clockwise (open) from the closed position.

•Turn the other valve (103), marked ‘‘F” at side of control as- sembly (93), clockwise until closed (do not tighten too snugly).

•Start the unit and slowly turn valve (103) marked ‘‘F” counter– clockwise (open) until the desired forward rate of feed is reached.

•A final adjustment of the rate of return (retract) can be made with the valve (103) marked ‘‘R”.

•Disconnect air and electrical supply ‘‘BEFORE” performing maintenance or service to tool.

•Never apply excessive pressure by a holding device which may cause distortion of a part.

•Apply pressure evenly to parts which have a press fit.

•Apply even pressure to the bearing race that will be press fitted to the mating part.

•Use correct tools and fixtures when servicing this tool.

•Don’t damage ‘‘O” rings when servicing this tool.

•Use only genuine ARO replacement parts for this tool. When ordering, specify part number, description, tool model number and serial number.
