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

• Keep hands and clothing away from rotating end of tool and all

moving parts of the 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.

ROUTINE LUBRICATION REQUIREMENTS

When this tool was built, an “O” ring lubricant was applied to all ap­propriate 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 ex­pect that external debris will not enter the tool. It is also reason­able 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.

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.

AIR SUPPLY REQUIREMENTS

For maximum operating efficiency, the following air supply specifi­cations should be maintained to this air tool:

• AIR PRESSURE – 90 PSIG (6 bar)

• AIR FILTRATION – 50 micron

• HOSE SIZE – 5/16” (8 mm) I.D.

An ARO R model P29231–110 air line FILTER/REGULATOR p l u s
100067 gauge is recommended to maintain the above air supply
specifications.

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:

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.

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”.
