MANUAL FOR SERIES

TD, TX AND TXD GRINDERS

Series TD, TX and TXD Grinders are designed for close–quarter work in the metal fabricating industry, shipyards, pipe fabrication, die manufacturing and limited space applications. They are particularly good where conduits, pipes, ducts, etc. pass through bulkheads or frames. These small Grinders are very efficient for grinding weld bead and leaving a fine finish.

Ingersoll–Rand is not responsible for customer modification of tools for applications on which Ingersoll–Rand was not consulted.

GRINDER SPECIFIC WARNINGS

FAILURE TO OBSERVE THE FOLLOWING WARNINGS COULD RESULT IN INJURY.

• Do not use this tool if actual free speed exceeds the

nameplate rpm.

• Before mounting a wheel, after any tool repair or

whenever a Grinder is issued for use, check free speed of Grinder with a tachometer to make certain its actual speed at 90 psig (6.2 bar/620 kPa) does not exceed 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 recommended Ingersoll–Rand

Wheel Guard furnished with the Grinder.

• Do not use any grinding wheel, bur or other

accessory having a maximum operating speed less than the free speed of the Grinder in which it is being used. Always conform to maximum rpm on grinding wheel blotters.

• 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 grinding wheel properly fits the

arbor. Do not use reducing bushings to adapt a wheel to any arbor unless such bushings are supplied by and 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 a wheel is defective, improperly mounted or the wrong size and speed, this is the time it will usually fail.

WARNING

Always wear hearing protection when operating this tool.

WARNING

Do not carry the tool by the hose.

WARNING

Operate at 90 psig (6.2 bar/ 620 kPa) Maximum air pressure.

• When starting with 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 wheel flanges are at least 1/3 the

diameter of grinding wheel, free of nicks, burrs and sharp edges. Always use wheel flanges furnished by the manufacturer; never use a makeshift flange or a plain washer. Tighten Flange Nut securely.

• Guard opening must face away from operator.

Bottom of wheel must not project beyond guard.

• Series TD120 Grinders have a free speed of 12,000

rpm; Series TD180, TX180 and TXD180 Grinders have a free speed of 18,000 rpm; Series TD200 and TX200 Grinders have a free speed of 25,000 rpm, when operated at 90 psig (6.2 bar/620 kPa) air pressure. Operation at higher air pressure will result in excessive speed.

• Always match collet size with accessory shank size.

• Always insert tool shank no less than 10 mm in the

collet. Tighten Collet Nut securely to prevent accessory from working out during operation of the Grinder. Check tightness of Collet Nut before operating the Grinder. Pay particular attention to the fact that allowed speed of a mounted point is lowered when the length of the shaft is increased between end of collet and mounted point (overhang).

WARNING

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.

WARNING

Do not use damaged, frayed or deteriorated air hoses and fittings.

AVERTISSEMENTS SPECIFIQUES AUX MEULEUSES

ATTENTION

LE NON RESPECT DES AVERTISSEMENTS SUIVANTS PEUT CAUSER DES BLESSURES

• 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

l’outil ou avant de fournir une meuleuse pour utilisation, vérifier la vitesse à vide de la meuleuse avec un tachymètre pour s’assurer que la vitesse réelle à 6,2 bar (620 kPa) 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 protège–meule Ingersoll–Rand

fourni avec la meuleuse.

• Ne jamais utiliser une meule, une fraise ou tout autre

accessoire ayant une vitesse de service inférieure à la vitesse à vide de la meuleuse sur laquelle il est monté. Respecter toujours la vitesse maximum inscrite sur les disques en papier de la meule.

• Inspecter toutes les meules avant de les monter pour

vérifier qu’elles 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 l’eau ou tout autre liquide.

• S’assurer que la meule se monte correctement sur

l’arbre. 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 en acier ou dans une pièce coulée et la faire tourner pendant au moins 60 secondes. S’assurer 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,

l’appliquer 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 protège–meule endommagé,

tordu ou très usé. Ne pas utiliser un protège–meule qui a été soumis à la rupture d’une meule.

• S’assurer que les flasques de meule couvrent au moins

1/3 du diamètre de la meule, et qu’ils sont exempts d’entailles, de bavures et d’arêtes vives. Utiliser toujours les flasques fournis par le fabricant; ne jamais utiliser de flasque de provenance douteuse ou de rondelle plate. Serrer fermement l’écrou du flasque.

• L’ouverture du protège–meule doit être orientée côté

opposé à l’opérateur. Le bas de la meule ne doit pas dépasser le protège–meule.

• Les meuleuses de la Série TD120 ont une vitesse à vide

de 12.000 tr/mn; les meuleuses des Séries TD180, TX180 et TXD180 ont une vitesse à vide de 18.000 tr/mn; Les meuleuses des Séries TD200 et TX200 ont une vitesse à vide de 25.000 tr/mn lorsqu’exploitées avec une pression d’air de 6,2 bar (620 kPa). L’exploitation à une pression supérieure produira une vitesse excessive.

• Toujours choisir une pince adaptée à la dimension de

la queue de l’accessoire.

• 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 que su velocidad real a 90 psig (620 bar/6,2 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 Ingersoll–Rand

recomendado y suministrado con la Amoladora.

• No use nunca una muela, taladro rotatorio dental o

cualquier otro accesorio que tenga una velocidad máxima de funcionamiento menor que la velocidad libre de la Amoladora en la que se esté usando. Cumpla siempre las rpm máximas indicadas en los distanciadores de la muela.

• 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 de que la muela esté bien puesta en la

espiga. No use anillos reductores para adaptar una muela a la espiga a menos que estos hayan sido suministrados y 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, abrasiones y bordes afilados. Use siempre las bridas de muela suministradas por el fabricante; no use nunca una brida casera o arandela normal. Apriete la Tuerca de Brida de manera segura.

• La apertura del cubremuela deberá estar orientada hacia afuera del operario. La parte inferior de la muela no deberá proyectarse fuera del cubremuela.

• Las Amoladoras Modelos TD120 tienen una velocidad libre de 12.000 rpm; Las Amoladoras Modelos TD180, TX180 y TXD180 tienen una velocidad libre de 18.000 rpm; Las Amoladoras Modelos TD200 y TX200 tienen una velocidad libre de 25.000 rpm cuando se operan a una presión de aire máxima de 90 psig (6,2 bar/ 620 kPa). Si se utiliza la herramienta a una presión de aire comprimido mayor, se causará exceso de velocidad.
