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). If an in line or air line lubricator is not used, apply several drops of spindle oil (29665) in air inlet.
EVERY 40 HOURS OF TOOL OPERATION – Flush tool with a solution of three (3) parts cleaning solvent to one (1) part spindle oil.
AIR SUPPLY REQUIREMENTS
For maximum operating efficiency, the following air supply specifi- cations should be maintained to this air tool:
•AIR PRESSURE – 90 p.s.i.g. (6.2 bar)
•AIR FILTRATION – 50 micron
•LUBRICATED AIR SUPPLY
•HOSE SIZE – 3/16” (5 mm) I.D.
An AROR model
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:
Where Used | ARO Part # | Description |
Air Motor | 29665 | 1 qt Spindle Oil |
‘‘O” Rings | 36460 | 4 oz. Stringy Lubricant |
Bearings | 33153 | 5 lb. ``EP" - NLGI #1 Grease |
MOUNTING INSTRUCTIONS
•Be sure collet is in good condition and properly secured to grinder spindle.
•Insert shaft of mounted wheel to the full depth of gripping jaws of collet. At least
•Be sure mounted stone or carbide bur is compatible with the speed of the grinder.
CAPACITIES (MAXIMUM)
•Carbide Bur – 1/4”
•Mounted Stone – 1/4”
INSPECTION, MAINTENANCE AND INSTALLATION
Disconnect air supply from the tool or shut off air supply and ex- haust (drain) line of compressed air before performing mainte- nance or service to the tool.
It is important that the tools be serviced and inspected at regular intervals for maintaining safe,

Be sure the tool is receiving adequate lubrication, as failure to lu- bricate 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, competent personnel. Tools, hose and fittings shall be re- placed if unsuitable for safe operation and responsibility should be assigned to be sure that all tools requiring guards or other safe- ty devices shall be kept in legible condition. Maintenance and re- pair records should be maintained on all tools. Frequency of repair and the nature of the repairs can reveal unsafe application. Scheduled maintenance by competent authorized personnel should detect any mistreatment or abuse of the tool and worn parts. Corrective action should be taken before returning the tool for use.
Disassembly should be done on a clean work bench with a clean cloth spread to prevent the loss of small parts. After disassembly is completed, all parts should be thoroughly washed in a clean sol- vent, blown dry with air and inspected for wear levels, abuse and contamination. Double sealed or shielded bearings should never be placed in solvent unless a good method of
Upon reassembling, lubricate parts where required. Use 33153 grease, or equivalent, in bearings. Use 36460 lubricant for ‘‘O” ring assembly. When assembling ‘‘O” rings or parts adjacent ‘‘O” rings, care must be exercised to prevent damage to the rubber sealing surfaces. A small amount of grease will usually hold steel balls and other small parts in place while assembling.
When replacement parts are necessary, consult drawing contain- ing the part for identification.
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 pres- sure (less than 90 p.s.i.g.) reduces the speed of the air tool. High air pressure (more than 90 p.s.i.g.) raises performance beyond the rated capacity of the tool and could cause injury. Shown below is a typical piping arrangement.
