Operation InstructionsThis manual is broken down into step by step instructions to assist the operator in easy and quality food preparation. This manual should be read completely before use by each operator. Additionally, this manual should be kept as a reference for future operators. Adherence to the guidelines set forth by this manual will ensure a safe, long life utilization of the vertical cutter mixer.A. Blade AssemblyThe R10 blade assembly comes assembled from the factory. The blade assembly is designed so that the blades can be adjusted for large or small batches. The blade assembly should be completely disassembled after each days use, washed completely, and allowed to air dry before reassembled. Additionally, the blades should be kept sharp to provide the best performance. The blades can be sharpened by means of a fine stone; a stone is provided with each machine.The blades are set at the factory to allow for most operations (See figure). The bottom blade should always stay on the bottom, followed by one small spacer, then the second blade, followed by the second smaller spacer then the third blade. Note: the white Nylon spacer should always be used between the locking nut and large aluminum spacer. Most low speed operations can be run using this blade configuration. High speed operations and operations using heavy loads such as dough and cheese should use only two blades. For high speed operations, use only one small spacer between the lower and second blade.Use the following diagram as a guide. NOTE: The placement of the blades is very important to maintain thespacers and blades for cleaning. Allow all parts to dry before reassembly. A light food grade grease may be applied to the threaded area to assist in easy removal.If the blades are not disassembled on a regular basis, they will become hard to disassemble and adjust. If the blade locking nut will not remove, service may be required.MINI BOWL INSTRUCTIONSFOR MODEL R10UThe Robot Coupe Model R10 Vertical Cutter Mixer has available a 3 1/2 quart mini bowl attachment. The mini bowl kit may be purchased with the machine as model R10U or separate as part number R8U090.The mini bowl fits inside the larger 10 quart bowl and uses the same lid. Extra mini bowl kits may be purchased and are available through the regular distribution network.Included in the mini bowl kit is a 3 1/2 quart bowl, S-blade assembly with disassembly tool, and gasket for lid.ASSEMBLY OF THE MINI BOWLThe mini bowl fits inside the larger 10 quart bowl and is held in place by the lid. To assemble the mini bowl, secure the larger 10 quart bowl and lid assembly to the motor base. The center stem of the large bowl has a notch cut into the top which fits to a pin located on the under side of the mini bowl. Place the mini bowl down on to the center stem of the large bowl and rotate until the pin of the mini bowl drops into the notch of the large bowl stem. Note: The large S-blade is not used with the mini bowl assembly. The mini bowl must be fully seated on the stem to work correctly.Place the mini bowl gasket on to the center ring of the lid assembly with the bevel of the seal down. This seal secures the mini bowl in place when the lid is closed. Place the mini bowl S-blade assembly down into the bowl and over the motor shaft. Rotate the blade so that it drops completely on the shaft; the bottom blade should be located just off the bowl bottom when assembled correctly.The S-blade should be disassembled after each session or minimally once per day. Supplied with the mini bowl kit is a stainless steel rod. To disassemble the blade, place the small end of the tool into the hole of the top locking nut of the blade assembly. Lay the blade on its side on top of a cutting board and carefully rotate the locking nut counter clockwise to loosen. Wash each part separately and allow to air dry before reassembling. CAUTION: The blades are very sharp, wear protective cutting gloves when handling.SIDE VIEW OF SEALSEALMINI BOWLLARGE BOWL NOTCHLIDTOOL CLOCKWISE TO TIGHTEN COUNTERCLOCKWISE TO LOOSEN NYLON SPACER FRONT VIEWBOWL ASSEMBLYBLADE ASSEMBLYB. ControlsNote: The Robot Coupe model R10 is available with either a two speed motor, or a single speed motor. The single speed version of the R10 is the model R10P. The following section is written to detail the two speed machine (R10) controls. If you have purchased the model R10P, simple omit the reference to the two speed selector switch. All other controls are the same.The Robot Coupe model R10 is designed with an easy to use control panel. This machine offers a two speed selector switch, push button run switch, push button pulse switch, oversized mushroom type off switch, and a power on and running indicator lamps. The following gives a brief description of each.Two Speed Selector: This switch allows the user to select either Low (1725 RPM) or High (3450 RPM) speed for the operation. The middle position is a OFF position. For best results, the speed selector should only be moved while the machine is off and not running. A speed must be selected before the power on lamp will light, also the lid must be closed - closing the safety switch.Run Switch: This switch is used to start the machine. The machine will not run unless the lid/safety switch is closed and a speed has been selected.Pulse Switch This switch is used to jog or pulse the motor off and on. The machine will not pulse on unless the lid/safety switch is closed and the switch is in the low speed position.Stop Switch: The stop switch will stop the motor from running after the run switch has been pressed. Always use this switch to turn the machine off. Do not open the lid without pressing the off switch.Red (power) Indicator Lamp: This lamp will light when the machine is plugged in, the lid/safety switch is closed and a speed has been selected. NOTE: The red lamp will not light if the overload protector has been tripped.Green (running) Indicator Lamp: This will light when the machine is running.Automatic Overload Protection: The R10 is equipped with auto-reset thermal overload protection. If the unit overheats due to an overload condition, it will automatically shut off. After a cooling period of ten to fifteen minutes the thermal overload protection will automatically reset and the unit may then be restarted. It will not restart until the thermal overload has reset.The preceding description of the controls is considered as normal operating conditions. If for any reason they do not perform as indicated, the machine should be serviced. Additionally, the machine should not be operated if it has malfunctioned in any way until it has been checked out and repaired by a qualified service person. Robot Coupe authorized service agencies are located in most all areas across the United States. Refer to the list provided to locate the service company nearest you.C. OperationBecause of the special bowl and blade design of the Robot Coupe Vertical Cutter Mixers, most operations are completed in a matter of seconds. The operator should pay close attention to the product as well as the amount of time required to process. Operations should be run on Low speed, using High speed only when an extremely fine puree consistency is desired.There are two ways to run your unit. First of all, you may run the unit continuously by filling the bowl with food and simply letting it run until the desired consistency has been reached. Use this method to grind, mix, blend, puree, or emulsify. Secondly, you may chop with your unit by pulsing the machine.Cut round products into halves or quarters and prep long vegetables into 3 to 4 inch pieces. Place these into the bowl, and using Low speed, pulse the unit on and off quickly. Usually 4 to 5 pulses yields an evenly mixed chopped substance.SPECIAL NOTE: The model R10 three phase must be limited to no more than 80 pulses (quick starts and stops) within a one hour period. The model R10P single phase should be limited to 30 pulses per one hour period. Exceeding this limitation can cause damage to the electrical components of the machine which is not covered under warranty. The R10 does not pulse on high speed.TO CHOPTo achieve a chopped consistency for vegetables, cheese, meats, etc. fill the bowl with the product no more than 3/4 full, or as low as two to three onions. Small batches would require lowering the top cutting blade. With the lid secured, and the speed selector in Low speed, press the pulse button quickly then release. Repeat this pulsing action, allowing the blades to stop each time, until the desired cut is achieved.TO PUREE OR MIXFill the bowl with the product no more than 3/4 full. Start the machine in Low speed and allow to run until the product is completely reduced. If necessary, turn the machine off and select High speed to finish the product. It may be necessary to add some liquids to a puree to achieve the desired consistency. If a complete homogeneous mixture is required for analytical testing, it may be required to scrape the walls of the bowl one time during processing to complete the homogenous mixture.DOUGHS AND PASTRIESPrepare doughs and pastries on Low speed only. In many cases it may be helpful to first mix all dry products then add the liquids. The unit should be run continuously until the product is completely processed. For thick doughs, such as for pizza, the machine will form a ball of dough when the mixing is complete. When a ball is formed the machine should be turned off immediately to prevent over processing. Preparation times and all ingredients should be noted for different recipes.D. EMPTYING THE BOWLAfter the product has been run in the bowl, make certain that the speed selector is in the middle off position, and for extra safety unplug the machine. NEVER attempt to open the lid until the blades have come to a complete stop.To remove the bowl, loosen the knob on the front of the bowl and twist the bowl clockwise, thus releasing the locking lugs. Then lift the entire bowl, with the blade assembly intact, up and off of the motor shaft. The bowl can then be emptied by holding the blade in place and tilting the bowl to one side into a catch pan or other container.CAUTION: The blades are sharp, use extreme caution while working with the blades.E. CLEANINGCleaning is one of the most important measures to ensure safe, quality food preparation. The machine should be cleaned after each session. Failure to keep the machine clean can result in high repair costs and shortened machine life. Follow the cleaning instructions detailed below, or according to local Health Depart-ment Regulations.NOTE: The aluminum bowl lid and the blade assembly should be washed in a metal safe detergent. Deter-gents containing caustic soda will cause soft metals to oxidize leaving an undesirable black residue on the surface.The bowl, blades, and lid can be removed and cleaned in a pot sink or dishwasher. Take care not to bend, drop, or break any of the components.The lid is removed by removing the lid hinge pin located at the base of the lid. The blades can be lifted out, and the bowl removed by loosening the locking nut on front of the bowl and twisting the bowl clockwise.The blade assembly should be disassembled and cleaned completely. Assemble the blade only after it has dried completely.With the bowl removed, the motor shaft and seal should be cleaned. Use a soft brush or cloth to clean the seal area. The seal is designed to prevent penetration of liquids and food products into the motor housing. Clean the seal area completely, yet do not damage the seal. Do not allow food or liquids to remain built up around the seal area. The seal should not be cleaned by use of spraying water. Inspect the seal during each cleaning for damage or wear. This seal is designed for easy removal by use of a large wrench. The seal should be replaced if any wear or damage is noted. Contact an authorized service agent for additional seals. NOTICE: It is recommended that the seal be lubricated at least once a week or after cleaning as practical. A food grade grease, vegetable oil, or mineral oil will work well.Clean the motor base housing using a cloth lightly dampened with a soapy water solution. Clean the entire motor base by use of a soft cloth, pay special attention to the seal area and lid mounting plate. Maintaining a clean machine will improve the overall life of the unit. SPECIAL NOTE: This motor base assembly is not designed to be cleaned by use of spraying water. Pressure cleaning with water can cause damage to the electrical components contained within the housing. Do not allow the motor base to be sprayed or immersed in any liquid.R10 Operation ManualIII. PREVENTATIVE MAINTENANCEThe Robot Coupe Vertical Cutter Mixers are designed to give years of maximum trouble free performance. Adherence to the operating instructions as well as keeping the unit clean will further ensure good perfor-mance.An examination should be made periodically to assure that all parts are in good working condition.

Una de las semiesferas está provista de un grifo de cierre y de aireación. El equipo se completa con una manguera corta.Conexión de vacío: 8 mm Diámetro:120 mm Longitud de la manguera:110 mmLa tierra está cubierta por una capa de aire: la atmósfera. Tal como sucede con el resto de la materia, la fuerza de gravedad también atrae las moléculas de aire y, por tanto, éstas se concentran sobre la superficie terrestre. La presión atmosférica, ejercida por la masa de aire que rodea la tierra, tiene su mayor valor al nivel del mar, y disminuye si aumenta la distancia con respecto a la superficie terrestre. De manera análoga al comportamiento de los fluidos, la presión atmosférica actúa homogéneamente sobre todos los lados de un cuerpo determinado. En un cuerpo que posea una cavidad abierta, existe siempre un equilibrio entre la presión externa e interna del aire. Si la presión interna se vuelve menor a la externa, fluirá aire hacia el interior, con lo que se restablecerá el equilibrio. También en el caso contrario, si la presión interna se torna mayor a la externa, se mantiene la misma tendencia de equilibrio puesto que el aire fluirá hacia el exterior. Si el cuerpo se3B Scientific GmbH ▪ Rudorffweg 8 ▪ 21031 Hamburgo ▪ Alemania ▪ Nos reservamos el derecho a cambios técnicos© Copyright 2018 3B Scientific GmbHencuentra cerrado, en el primer caso, la fuerza resultante de la diferencia de presión entre el exterior y el interior actúa sobre la superficie del cuerpo, apretándolo, y, en el segundo caso, se ejerce una presión hacia afuera, la cual tiende a provocar la explosión del cuerpo.El físico y burgomaestre de Magdeburgo, Otto von Guericke, fue el primero en demostrar la acción de la presión atmosférica. Sus estudios sobre el vacío empezaron en 1650 y llegaron a la cima con el espectacular experimento del año 1654, realizado en Regensburgo: Las semiesferas de Magdeburgo, hecho que contó con la presencia del emperador Ferdinand III. Guericke evacuó dos semiesferas de cobre, de un diámetro de 42 cm, hermetizadas gracias a una junta formada por una correa de cuero impregnada de aceite y cera.
