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 IngersollRand 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.
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.

AVERTISSEMENTS SPECIFIQUES AUX MEULEUSES
Ne pas utiliser cet outil si la vitesse à vide réelle
dépasse celle indiquée sur la plaque signalétique.
Avant de monter une meule, après toute réparation de
loutil ou avant de fournir une meuleuse pour
utilisation, vérifier la vitesse à vide de la meuleuse
avec un tachymètre pour sassurer que la vitesse réelle
à 6,2 bar (620kPa) ne dépasse pas celle poinçonnée ou
imprimée sur la plaque signalétique. Les meuleuses
sorties sur chantier doivent être vérifiées de la même
façon au moins une fois par poste.
Utiliser toujours le protègemeule IngersollRand
fourni avec la meuleuse.
Ne jamais utiliser une meuleuse sans son
protègemeule recommandé. Ne jamais utiliser de
meule dont la vitesse de fonctionnement imprimée sur
l’étiquette est inférieure à la vitesse à vide de
meuleuse.
Inspecter toutes les meules avant de les monter pour
vérifier quelles ne présentent pas d’éclats ou de
fissures. Ne jamais utiliser une meule écaillée, fissurée
ou ayant un endommagement quelconque. Ne jamais
utiliser une meule qui a été trempée dans leau ou tout
autre liquide.
Sassurer que la meule se monte correctement sur
larbre. Le montage de la meule ne doit être ni serré ni
libre. Les meules à trou lisse doivent présenter un jeu
diamétrial maximum de 0,17 mm. Ne pas utiliser de
bagues réductrices, à moins que ces bagues soient
recommandées et fournies par le fabricant de la
meule.
Après avoir monté une nouvelle meule, tenir la
meuleuse sous un établi enacier ou dans une pièce
coulée et la faire tourner pendant au moins 60
secondes. Sassurer que personne ne se tient dans le
plan de rotation de la meule. Toute meule défectueuse,
mal montée ou de dimension et vitesse incorrectes se
cassera généralement à ce moment là.
Pour commencer le travail avec une meule froide,
lappliquer lentement contre la pièce jusqu’à ce que la
meule s’échauffe progressivement. Mettre la meule en
contact avec la pièce en douceur en évitant tout choc
ou pression excessive.
Remplacer toujours un protègemeule endommagé,
tordu ou très usé. Ne pas utiliser un protègemeule qui
a été soumis à la rupture dune meule.
Sassurer que les flasques de meule couvrent au moins
1/3 du diamètre de la meule, et quils sont exempts
dentailles, de bavures et darêtes vives. Utiliser
toujours les flasques fournis par le fabricant; ne
jamais utiliser de flasque de provenance douteuse ou
de rondelle plate.
Louverture du protègemeule doit être orientée côté
opposé à lopérateur. Le bas de la meule ne doit pas
dépasser le protègemeule.

AVISOS ESPECÍFICOS PARA AMOLADORA
No use esta herramienta si la velocidad libre real
excede la indicada en la placa de identificación.
Antes de montar una muela, y después de todas las
reparaciones de herramienta y siempre que se
proporcione una Amoladora para su uso, compruebe
la velocidad libre de dicha Amoladora con un
tacómetro para asegurarse de que su velocidad real a
90 psig (6,2 bar/620 kPa) no exceda las rpm
estampadas o impresas en la placa de identificación.
Las Amoladoras usadas en trabajos deberán ser
examinadas similarmente como mínimo una vez en
cada jornada de trabajo.
Use siempre el Cubremuela IngersollRand
suministrado con la Amoladora.
No use una Amoladora sin el cubremuela
recomendado. No use ninguna muela que tenga una
velocidad de funcionamiento, tal y como aparece en el
distanciador, menor que la velocidad libre real de la
amoladora.
Inspeccione todas las muelas antes de su montaje para
ver si tienen grietas o roturas. No use una muela que
esté rota o agrietada o dañada de cualquier otra
forma. No use una muela que haya estado a remojo en
agua o en cualquier otro líquido.
Asegúrese que la muela esté bien puesta en la espiga.
La muela no debe estar muy floja ni muy apretada.
Las muelas de orificio normal deberán tener una
holguta diamétrica máxima de aproximadamente
0,007 pulg. (0,17 mm). No use aros reductores para
adaptar una muela a la espiga a menos que éstos
hayan sido suministrados o recomendados por el
fabricante de muelas.
Después de haber montado una muela nueva, sujete la
Amoladora bajo un banco de acero o en un molde y
hágala funcionar durante 60 segundos como mínimo.
Asegúrese que no haya nadie en el entorno de
operación de muela. Si la muela es defectuosa, está
mal montada o es del tamaño y velocidad incorrectas,
normalmente fallará en este momento.
Cuando ponga en marcha una muela en frío ,
aplíquela lentamente al trabajo hasta que se caliente
gradualmente. Contacte la zona de trabajo
suavemente, y evite golpes o exceso de presión.
Cambie siempre un cubremuela dañado, torcido o
muy desgastado. No use un cubremuela que haya
experimentado un fallo de muela.
Asegúrese que las bridas de muela sean de un
diámetro mínimo de 1/3 de la muela y que estén libres
de marcas, rebabas y bordes afilados. Use siempre las
bridas de muela suministradas por el fabricante; no
use nunca una brida casera o arandela normal.
La apertura del cubremuela deberá estar orientada
hacia afuera del operario. La parte inferior de la
muela no deberá proyectarse fuera del cubremuela.
Use siempre un distanciador entre cada brida de
muela y muela. Los distanciadores deberán ser de un

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
IngersollRand 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.
Certifiquese 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.
Depois de montar uma mó abrasiva nova, segure o
Rectificador sob uma bancada de aço ou dentro de
uma peça fundida e ponhao a funcionar durante pelo
menos 60 segundos. Certifiquese 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, apliquea
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.
Certifiquese 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.

Always wear eye protection when operating or
performing maintenance on this tool.
Always turn off the air supply and disconnect the air
supply hose before installing, removing or adjusting
any accessory on this tool, or before performing any
maintenance on this tool.
LUBRICATION
Whenever a Series 88V Grinder is disassembled for
overhaul or replacement of parts, lubricate as follows:
1. Inject about 1.5 cc of IngersollRand No. 50 Oil into
the Inlet Bushing (4) after assembly.
2. If the Grinder is used in an extremely dirty
environment, once each week or after each forty
hours of operation, pour a liberal amount of a
suitable cleaning solution into the slots in the handle.
Work the throttle lever vigorously to wash the
cleaning solution around, and then pour the solution
and accumulated dirt from the handle. Repeat this
process until the cleaning solution is clean when it
comes out of the handle. Immediately after flushing
with the cleaning solution, inject a liberal amount of
IngersollRand No. 50 Oil in the slots and, again,
work the throttle lever vigorously to lubricate the
cleaned parts.

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.

If replacement is necessary, wipe the part with oil. Press the Arbor Bearing into the Front End Plate. 3. Hold the Arbor in leather–covered or copper–covered vise jaws. Insert the Rotor Key (30) in the slot of the Rotor (31). The Rotor has a staked keyway on one end. Place that end up, over the Arbor. Apply a light film of the recommended oil to each Vane (32) and insert one vane, straight edge out, into each slot in the Rotor. If any new vanes are required, replace the entire set. 4. Place the Cylinder over the Rotor matching the Cylinder Dowel hole to the alignment hole in the Front End Plate (29), with the kidney port to the right of the dowel hole. 5. Apply the Rear End Plate (35) with the kidney port to the right of the dowel hole. Use only the special No. 88V60–950 Controller Wrench for applying the assembly. Take all measurements 30 degrees to the left of the dowel hole when facing the hub side of the Seal. Install the Rotor Bearing Seal hub down. 10. 11. Prior to tool assembly, carefully inspect the Controller Assembly for nicks, gouges or dents. Replace it with a new Controller Assembly if necessary. Test free speed before applying a grinding wheel. 12. 13. If the Controller Assembly (37) needs to be replaced, you must also replace the Rotor Bearing Seal Assembly (38) which consists of a rear rotor bearing and a rotor bearing seal. If either the rear rotor bearing or rotor bearing seal needs to be replaced, BOTH must be replaced with a new bearing and seal. Do not mix old and new parts. 6. Check the outside diameter and large inside diameter of the Rotor Bearing Seal (38) for wear. If the outside diameter is worn to 1.1764” (29.881 mm) or smaller, and/or the large inside diameter is worn to 0.9103” (23.122 mm) or larger, install a new Rotor Bearing Seal. 14. 15. 16. 19 Tighten the Controller to 14 to 16 ft–lb (19.0 to 21.7 Nm) torque. Do not exceed 16 ft–lb. The Controller may be damaged if this torque is exceeded. Always check the free speed of a Grinder after it has been reassembled and before it is put back into service. Refer to the Test and Inspection Procedure. Never use a Grinder which runs in excess of the maximum speed listed in the Test and Inspection Procedure. Install the Controller Retaining Ring (40), concave face closest to the Controller. Place the lever handle in leather–covered or copper– covered vise jaws, open end of the Cylinder Case Assembly up. Lightly dampen the Rear End Plate Gasket (36) with oil and line it up with the hole in the Cylinder Case so that the notch in the Gasket matches the Cylinder Case. 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.
