Keep hands and clothing away from rotating end of tool.
l
Wear suitable eye protection while operating tool.
Disconnect air supply from tool before removing/installing bit
or performing other maintenance procedures.
ROUTINE LUBRICATION
REQUIREMENTS
Lack of or an 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 lubricator reser-
voir of recommended F.R.L. with spindle oil (29665).
EVERY 160 HOURS OF TOOL OPERATION
- Inject NLGI #1
"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 1/8 oz. (3.5 g) of grease.
AIR SUPPLY REQUIREMENTS
For maximum 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
l
LUBRICATED AIR SUPPLY
l
HOSE SIZE - 5/16" (8 mm) I.D.
An ARO@ 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 (41) is provided with 1-7/16" -
18 L.H. threads [remove thread guard (47) for use] and a 1-7/1 6" x
1/2" long pilot diameter for fixture mounting. Foot and flange type

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 or valves and adjustment screws and/or trip bracket.
Loosen two screws (29) 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 (26) equals
the total stroke length.
Tighten jam nut (8).
Loosen jam nut (8) and turn adjustment screw "B" (valve in-
head models only) so the distance between the end of the
screw and the button bleed valve (25) is slightly GREATER
than the distance set for adjustment screw "A".
Start and let the unit advance until the adjustment screw "A"
makes contact with the stud (26).
Carefully, and be aware that the unit is going to retract, turn the
adjustment screw "B" until it depresses the button bleed valve
(25) enough to cause the unit to retract.
Tighten jam nut (8).
