Keep hands and clothing away from rotating end of tool.

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 air line lubricator

reservoir of recommended F.R.L. with spindle oil (29665).

EVERY 160 HOURS OF TOOL OPERATION

- Inject NLGI #l

"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 1/4 oz. (7 g) of grease per set of gears.

AIR SUPPLY REQUIREMENTS

For maximum operating efficiency, the following air supply specifi-

cations should be maintained to this air tool:

AIR PRESSURE - 90 PSIG (6 bar)

AIR FILTRATION - 50 micron

LUBRICATED AIR SUPPLY

HOSE SIZE - 3/8" (10 mm) I.D.

An AR0® 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 (40) is provided with 2-1/2" - 16

L.H. threads (remove thread guard [45] for use) and a 2-1/2" x

1-1/4" long pilot diameter for fixture mounting. Foot and flange

type mounting brackets are available for tool mounting.

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 (11) 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 (28) equals

the Total Stroke Length.

lighten jam nut (8).

Loosen jam nut (8) and turn adjustment screw"B" so the dis-

tance between the end of the screw and the button bleed

valve (27) is slightly GREATER than the distance set for ad-

justment screw "A".

Start and let unit advance until the adjustment screw "A

makes contact with the stud (28).

Carefully, and be aware that the unit is going to retract, turn the

adjustment screw "B" until it depresses the button bleed valve

(27) enough to cause the unit to retract.

Tighten jam nut (8).

See "FEED RATE CONTROL VALVES", page 2.

THIS DISTANCE MUST EQUAL

TOTAL STROKE LENGTH
