COVERING: SAFETY PRECAUTIONS & PLACING INTO SERVICE
AIR OPERATED SELF- -FEED TOOLS
It is the responsibility of the employer to place this information into the hands of the operator.
AIR SUPPLY REQUIREMENTS
For maximum operating efficiency, the following air supply specifications should
be maintained to this air tool:
D MAXIMUM AIR PRESSURE - - 90 p.s.i.g. (6.2 bar)
D AIR FILTRATION - - 50 micron
D LUBRICATED AIR SUPPLY
D HOSE SIZE - - 8660- - ( )- - ( )EU: 3/8" (10 mm) I.D.
8670- - ( )- - ( )EU: 1/2" (13 mm) I.D.
An AROR air line FILTER/REGULATOR/LUBRICATOR (F.R.L.) is recom-
mended to maintain the above air supply specifications.
8660- - ( )- - ( )EU: C28231- - 810 F.R.L.
8670- - ( )- - ( )EU: C28241- - 810 F.R.L.
Always use clean, dry air. Dust, corrosive fumes and/or excessive moisture can
damage the motor of an air tool. An air line filter can greatly increase the life of an
air tool. The filter removes rust, scale, moisture and other debris from the air lines.
Low air pressure (less than 90 p.s.i.g., 6.2 bar) reduces the speed of the air tool.
High air pressure (more than 90 p.s.i.g., 6.2 bar) raises performance beyond the
rated capacity of the tool and could cause injury. Shown below is a typical piping
arrangement.

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:

Air Motor 29665
''O" Rings & Lip Seals 36460
Gears and Bearings 33153
OPERATION
Lack of or an excessive amount of lubrication will affect the performance and life
of this tool. Use only recommended lubricants at below time intervals:
EVERY 8 HOURS OF TOOL OPERATION - Fill lubricator reservoir of recom-
mended F.R.L. with spindle oil (29665).
EVERY 40 HOURS OF TOOL OPERATION - Flush tool with a solution of three
(3) parts cleaning solvent to one (1) part spindle oil. After flushing, apply a small

EVERY 160 HOURS OF TOOL OPERATION - Inject grease (33153) thru
grease fitting located at top of main housing for lubrication of gearing and spindle
bearings. NOTE: Be sure tool is in the fully retracted position when injecting
grease thru fitting. Gearing should contain approximately 1/4 oz. (7 g) of grease
per reduction.
The nose end of the tool is provided with threads and a pilot diameter for fixture
mounting (see below). A foot type mounting bracket and nose housing is avail-
able for tool mounting.

INSPECTION AND MAINTENANCE
It is important that the tools be serviced and inspected at regular intervals for
maintaining safe, trouble- - free operation of the tool.
Be sure the tool is receiving adequate lubrication, as failure to lubricate can
create hazardous operating conditions resulting from excessive wear.
Be sure that the air supply lines and connectors are of proper size to provide a
sufficient quantity of air to the tool.
Tool maintenance and repair shall be performed by authorized, trained, compe-
tent personnel. Tools, hose and fittings shall be replaced if unsuitable for safe op-
eration and responsibility should be assigned to be sure that all tools requiring
guards or other safety devices are so equipped. Critical rating markings on the
tool shall be kept in legible condition. Maintenance and repair records should be
maintained on all tools. Frequency of repair and the nature of the repairs can re-
veal unsafe application. Scheduled maintenance by competent authorized per-
sonnel should detect any mistreatment or abuse of the tool and worn parts.
Corrective action should be taken before returning the tool for use.
SET- - UP PROCEDURE
D Loosen 4 screws and remove cover.
D Allow a minimum distance of 1/4" (6 mm) between the drill point of the tool
and the work piece. This is necessary for the air motor to start and reach free
speed before the drill point touches the work piece.
D Determine the ''total stroke length" the drill must travel to perform the drilling
operation.
D Loosen the 2 cap screws that secure the trip bracket to the piston rod.
D Position the trip bracket on the piston rod so the distance between the trip
bracket and the striker plate is slightly greater than the desired stroke length.
D Tighten 2 cap screws, securing the trip bracket to the piston rod.
D Turn adjustment screw so the distance between the end of the screw and the
striker plate equals the ''total stroke length".
D A final adjustment of the adjustment screw can be made while testing the dril-
ling operation on a few scrap work pieces to insure the desired drilling depth
is obtained.
