WARNING Keep body stance balanced and firm. Do not overreach when operating this tool. GRINDER SPECIFIC WARNINGS • • • • • • • Do not use this tool if the actual free speed exceeds the nameplate rpm. Before mounting a wheel, after all tool repairs and whenever a Grinder is issued for use, check the free speed of the Grinder with a tachometer to make certain its actual speed at 90 psig (6.2 bar/620 kPa) does not exceed the rpm stamped or printed on the nameplate. Grinders in use on the job must be similarly checked at least once each shift. Always use the Ingersoll–Rand Wheel Guard furnished with the Grinder. Do not use a Grinder without the recommended wheel guard. Do not use any wheel for which the operating speed listed on the blotter is lower than the actual free speed of the Grinder. Inspect all grinding wheels for chips or cracks prior to mounting. Do not use a wheel that is chipped or cracked or otherwise damaged. Do not use a wheel that has been soaked in water or any other liquid. Make certain the grinding wheel properly fits the arbor. The wheel should not fit too snugly or too loosely. Plain hole wheels should have about 0.007” (0.17 mm) maximum diametral clearance. Do not use reducing bushings to adapt a wheel to any arbor unless such bushings are supplied by or recommended by the wheel manufacturer. • • • • • • 2 After mounting a new wheel, hold the Grinder under a steel workbench or inside a casting and run it for at least 60 seconds. Make certain no one is within the operating plane of the grinding wheel. If the wheel is defective, improperly mounted or the wrong size and speed, this is the time it will usually fail. When starting a cold wheel, apply it to the work slowly until the wheel gradually warms up. Make smooth contact with the work, and avoid any bumping action or excessive pressure. Always replace a damaged, bent or severely worn wheel guard. Do not use a wheel guard that has been subjected to a wheel failure. Make certain the wheel flanges are at least 1/3 the diameter of the grinding wheel, free of nicks and burrs and sharp edges. Always use the wheel flanges furnished by the manufacturer; never use a makeshift flange or a plain washer. Guard opening must face away from operator. Bottom of wheel must not project beyond guard. Always use a wheel blotter between each wheel flange and the wheel. The blotters must be at least as large in diameter as the wheel flanges. Do not attempt to disassemble the Controller. The Controller is available only as a unit and is guaranteed for the life of the tool if it is not abused.  PLACING TOOL IN SERVICE WARNING: Incorrect combinations of grinding wheel, wheel guard and tool speed could result in injury.

ADVERTÊNCIAS ESPECÍFICAS PARA O RECTIFICADOR • • • • • • • Não utilize esta ferramenta se a velocidade livre real ultrapassar o valor de rpm indicado na placa de identificação. Antes de montar uma mó abrasiva, após todas as reparações da ferramenta ou sempre que o Rectificador for ser utilizado, verifique a velocidade livre do mesmo com um taquímetro para assegurar que a sua velocidade real a 90 psig (6,2 bar/620 kPa) não ultrapassa o valor de rpm gravado ou impresso na placa de identificação. Os rectificadores em uso numa tarefa devem ser verificados da mesma maneira, pelo menos uma vez em cada turno. Utilize sempre a Protecção de Mó Abrasiva Ingersoll–Rand recomendada e fornecida com o Rectificador. Não utilize um Rectificador sem a protecção de mó abrasiva recomendada. Não utilize nenhuma mó abrasiva cuja velocidade de funcionamento listada na anilha de sujeição seja inferior à velocidade livre do Rectificador. Inspeccione todas as mós abrasivas quanto a lascas ou rachas antes de as montar. Não utilize uma mó que esteja lascada, rachada, ou danificada de alguma maneira. Não utilize uma mó que tenha estado mergulhada em água ou em outro líquido qualquer. Certifique–se de que a mó abrasiva encaixa correctamente no veio. A mó abrasiva não deve encaixar demasiado apertada ou frouxa. As mós com orifício liso devem ter uma folga diametral máxima de cerca de 0,007 pol. (0,17 mm). Não utilize buchas redutoras para adaptar uma mó abrasiva a um veio, a menos que a bucha seja fornecida ou recomendada pelo fabricante da mó. • • • • • • 11 Depois de montar uma mó abrasiva nova, segure o Rectificador sob uma bancada de aço ou dentro de uma peça fundida e ponha–o a funcionar durante pelo menos 60 segundos. Certifique–se de que não há ninguém dentro do plano de operação da mó abrasiva. Se a mó estiver com defeito, montada incorrectamente ou for de tamanho ou velocidade errada, é geralmente nesta altura que ela falhará. Ao começar a trabalhar com uma mó fria, aplique–a ao trabalho lentamente, até a mó aquecer gradualmente. Faça contacto suave com o trabalho e evite qualquer acção instável ou pressão excessiva. Substitua sempre uma protecção de mó abrasiva danificada, curvada ou muito gasta. Não utilize uma protecção que tenha sido sujeita a uma falha de mó abrasiva. Certifique–se de que as flanges da mó têm pelo menos 1/3 do diâmetro da mó abrasiva, estão livres de entalhes e rebarbas e de bordas afiadas. Utilize sempre as flanges de mó fornecidas pelo fabricante; nunca utilize uma flange improvisada ou uma anilha comum. A abertura da protecção deve ficar voltada para longe do operador. O fundo da mó não deve ficar saliente além da protecção. Utilize sempre uma anilha de sujeição de mó abrasiva entre cada flange de mó e a mó. As anilhas de sujeição devem ter, pelo menos, o mesmo diâmetro das flanges de mó. Não tente desmontar o Controlador. O Controlador só está disponível como uma unidade e é garantido durante a vida útil da ferramenta, se não for maltratado.  COLOCAÇÃO DA FERRAMENTA EM SERVIÇO ADVERTÊNCIA: Combinações incorrectas de mó abrasiva, protecção da mó abrasiva e velocidade da ferramenta podem resultar em lesões pessoais.

With an assembly dowel, line up the motor in the Cylinder Case. Remove the assembly dowel and insert the Cylinder Dowel (34). Install the two Motor Clamp Washers (41) concave or dish side up. Apply the Cylinder Case Gasket (42), the proper Guard (43 or 44), the Cylinder Case Screw Lock Washers (45) and the five Screws (46). Slightly tighten opposite screws, make sure the arbor is free, then tighten all screws to 14 ft–lb (19 Nm) torque. Again make certain the Arbor is free. The Dead Handle (25) may be adjusted to two positions. Insert a 5” (127 mm) long 3/16” hex wrench into the elongated slot in the end of the Dead Handle and loosen the screw securing the Handle to the Cylinder Case. Rotate the Handle 180° and tighten the screw to 18 ft–lb (24.4 Nm) torque.  MAINTENANCE SECTION TEST AND INSPECTION PROCEDURE Model Disconnect the Grinder from the air supply hose or shut off air to the tool before proceeding with the test and inspection procedure. Run the performance tests at 90 psig (6.2 bar/620 kPa) air pressure at the inlet of the tool with an eight foot (2.44 m) length of 3/4” (19 mm) diameter air supply hose. Stamped Free Speed, rpm Min Max 88V60 6 000 5 650 6 050 88V77 7 700 7 250 7 750 Speed rpm Nm 88V60 1.89 2.6 5 000 88V77 1.65 2.2 6 000 88V85 1.60 2.2 6 500 3. There must be no objectionable leaks in any non–exhaust area. The Throttle must not leak when it is closed. 4. There must be no leaks past the closed Throttle that will run the motor. 5. The Grinder must start smoothly when the Throttle Lever is depressed and must shut off completely when the Throttle Lever is released. 6. The Grinder must be equipped with a spring–loaded window style Lever Lock (15). The Lever Lock must return to the locked position when the Throttle Lever is released. 7. The tool must run smoothly without noticeable vibration or unusual sound. 8. The Arbor (27) must turn freely with no evidence of brinnelled bearings. 9. The threads on the arbor must be free of nicks and damage. 10. The Nameplate must be legible, in place and securely fastened. Make replacement if necessary. 1. Without a wheel on the tool, operate the Grinder with the Throttle Lever fully depressed and check the free speed by applying a hand–held tachometer to the spindle end. The minimum and maximum allowable free speeds are as follows: Model Torque ft–lb 2. Test the Grinder motor for power to determine these minimum performance levels. The Throttle Lever must not be actuated repeatedly during the test. Depress the Lever and hold it in the open position until the test is complete. 20  MAINTENANCE SECTION TROUBLESHOOTING GUIDE Trouble Probable Cause Low power or low free speed Rough operation Scoring Air leaks Insufficient air pressure at the inlet Plugged Screens Solution Check air line pressure at the Inlet of the Tool. It must be 90 psig (6.2 bar/620 kPa). Clean the Inlet Bushing Screen in a clean, suitable, cleaning solution. If it cannot be cleaned, replace it. Never operate a Grinder without an Inlet Screen. Ingestion of dirt into the Grinder can, in some cases, cause an unsafe condition. Worn or broken Vanes Install a complete set of new Vanes. Worn or broken Cylinder Replace the Cylinder if it appears cracked or if the bore is wavy or scored. Improper lubrication or dirt Lubricate the Grinder as instructed in LUBRICAbuild–up in the motor TION SPECIFICATION. If lubrication does not result in satisfactory operation, disassemble the motor, and inspect and clean all parts. Worn or broken Rear Rotor Examine each Bearing. Replace the Rear Rotor Bearing or Front Rotor Bearing Bearing Seal Assembly if worn or damaged or replace the Front Rotor Bearing. Worn Rotor Key Replace the Key. Check the Arbor and Rotor for key slot wear and replace if necessary. Bent Arbor Mount the Arbor on centers. Check bearing diameter runout with an indicator. Replace the Arbor if runout exceeds 0.002” (0.051 mm) Total Indicator Reading. Improper assembly Make certain that all motor parts are properly aligned prior to clamping the motor assembly. Rotor Bearing Seal misalignment Loosen the Cylinder Case Screws. Rotate the spindle by hand to align the seal. Tighten the screws to 14 ft–lb (19 Nm) torque. Spindle must rotate freely. Worn Valve Seat or Valve Seat Replace worn parts. Washer Worn Throttle Valve Seals Replace both Seals. Worn Cylinder Case Gasket Replace the Gasket. between the Cylinder Case and the Guard Distorted face on the Cylinder Polish lightly using fine emery cloth on a flat metal plate to remove high spots. If the tool has been dropped and the Cylinder Case is damaged, replace it with a new Cylinder Case Assembly. SAVE THESE INSTRUCTIONS. DO NOT DESTROY. 21  NOTES 22  NOTES 23
