INSTALLING,

lKeep hands and clothing away from rotating end of tool.

lWear suitable eye protection while operating tool.

lDisconnect 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).

RECOMMENDED LUBRICANTS

Afterdisassembly 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:


Where		Used	-		Description
Air	Motor			29665	1 qt. Spindle Oil
“0” Rings	& Lip Seals			36460	4 oz. Stringy Lubricant
Gears and		Bearings		33153	5 lb. “EP”- NLGI #1 Grease

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.

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:

lAIR PRESSURE - 90 PSIG (6 bar)

lAIR 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 1-7/16”x 1/2” long pilot diameter for fixture mounting. Foot and flange type mounting brackets are available for tool mounting.

lLoosen two screws (29) and remove cover (1).

lAllow 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.

aDetermine the TOTAL STROKE LENGTH the drill must travel

to perform the drilling operation - see illustration below.

lLoosen 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.

lTighten jam nut (8).

aLoosen 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”.

0Start and let the unit advance until the adjustment screw “A” makes contact with the stud (26).

lCarefully, 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. l lighten jam nut (8).
