MAINTENANCE

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 tool.

Tool maintenance and repair should be performed by authorized, trained, competent personnel. Maintenance and repair records should be maintained on all tools. Insure tool is receiving ade- quate lubrication, as failure to lubricate can create operating conditions resulting in excessive wear. Insure that the air supply lines and connectors are of the proper size to provide a sufficient quantity of air to the tool.

Air tools are made of precision parts and should be handled with reasonable care when servicing. Excessive pressure exerted by a holding device may cause distortion of a part. Apply pressure evenly when disassembling or assembling parts which have a press fit. When removing or installing bearings, apply pressure to the bearing race that will be the press fit to the mating part; if this is not practiced, Brinelling of the bearing races may occur, making replacement necessary. It is important that the correct tools and fixtures are used when servicing this air tool.

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 a solvent unless a good method of relubricating the bearing is available. Open bearings may be washed but should not be allowed to spin while being blown dry. When replacement- parts are necessary, consult the drawing containing the part.

Before reassembling, lubricate parts where required. Use ARO 33153 grease, or equivalent, in bearings. Use ARO 36460 “0” ring lube for “0” ring assembly. When assembling “0” rings or parts adjacent to “0” 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 as- sembling.

When ordering parts, be sure to list part number, part name, model number and serial number of tool. Use only genuine ARO replacement parts.

DISASSEMBLY AND REASSEMBLY OF TOOL

Disconnect air supply from the tool or shut off the air supply and exhaust (drain) line of compressed air BEFORE performing main- tenance or service to the tool.

Before starting to disassemble or reassemble this tool (any part or completely), be sure to read “Maintenance Section”.

To minimize the possibility of parts damage, and for convenience, the steps for disassembly or reassembly listed on the following pages are recommended.

Listed below are the three (3) basic sections of the tool and instructions for removing them.

screws (Y154-53). Remove four (4) screws (Y154-54) and washers (Y14-10). Lift valve section to clear bracket (41235) and pull forward carefully to disengage air tubes (41219-). If air tubes remain with valve section, pull carefully to remove.

POWER UNIT SECTION

Remove four (4) screws (Y154-55) and washers (Y14-10) and pull motor and gearing section from housing section. If the unit is equipped with both drive and auxiliary gearing, remove four (4) screws (Y154-52) and washers (Y14-10) and pull gearing from motor section. Grasp end of rotor and pull to remove motor as- sembly from housing.

VALVE SECTION

Remove three (3) screws (Y154-53). housing assembly (45452) spring (49533) and spacer (44848) from the rear of the tool. Place a suitable wrench on flats of shaft (40516-1) and rotate shaft clockwise until bracket (41235) has advanced far enough forward so it no longer contacts stop trip tab (40523-1). If only the valve section is being removed from the tool at this time, replace spacer (44848), spring (49533) and housing (45452) and secure with

SPINDLE AND LEAD SCREW SECTION

The lead screw and nut assembly (45453-) can be serviced with- out removing the tool from the fixture mounting. To remove from or reassemble to tool, see “Lead Screw and Nut” on page 5.

For complete disassembly of a particular section, refer to the ap- propriate section contained in the following pages.

For additional maintenance information, the manual “Tips on Air Tools”, form 5946 (English) or form 2158-X (Spanish), is available at $5.00each, send request to: The ARO Corporation, One Aro Center, Bryan, Ohio 43506, Attn: “Sales Training”.
