The discussions contained in this part are designed not only to teach how to properly operate and maintain aircraft tires, but also to demonstrate why these techniques and procedures are necessary. We’ll make it easy to get rolling Many times we tend to ignore the necessary maintenance needed to keep the tires safe. With motorcycles, there are only two small contact patches for the rider to rely on, so it is extremely important to keep the tires in top condition. Tire failure may create a risk of property damage, serious personal injury or death. To reduce the risk of tire failure, we strongly recommend you read and follow all safety none contained in this brochure. Serious personal injury or death may result from a tire failure. Many tire failures are preceded by vibration, bumps, bulges or irregular wear. If a vibration occurs while riding your motorcycle, or you notice a bump, bulge or irregular wear, have your tires and motorcycle evaluated by a qualified service person. More commonly if air is lost, it will be gradual. http://aeronautike.com/userfiles/brother-p-touch-pt-80-user-manual.xml

If you do experience a blow out or sudden tire failure, the following none should be helpful: When the failure occurs, slowly decrease the amount of throttle, hold the handlebars firmly, and steer to maintain your lane position. Once the motorcycle has slowed and is fully under control, apply the brakes gently. Gradually pull over to the shoulder and come to a stop. This is an important requirement for tire safety and mileage. Your motorcycle owner’s manual will tell you the recommended cold inflation pressure. On some motorcycles, the recommended front and rear tire pressures will be different. The pressures stamped on the sidewall of the tire are only for maximum loads. On some occasions, these pressures will also be the manufacturers recommended settings as well. The tires will build excessive heat. This can cause a sudden tire failure that could lead to serious personal injury or death. The tires are more likely to be cut, punctured, or broken by sudden impact. Serious personal injury or death could result. Do not exceed the pressure indicated on the tire sidewall. Consult your owner’s manual for the recommended inflation and other tire none. Inflating an unsecured tire is dangerous. If it bursts, it could be hurled into the air with explosive force resulting in serious personal injury or death. Replace them when mounting new tires. Use caps (finger tight) on the valve stems to keep dust, dirt and moisture away from the valve. Be sure to use an accurate pressure gauge. Recheck the inflation pressure when the tire is cold. Normal riding causes tires to run hotter and inflation pressure to increase. If you release air when your tires are hot, you may dangerously under inflate your tires. Consult your local dealer for an inspection. We recommend avoiding extreme maneuvers, including sudden acceleration, maximum braking and hard cornering, until you have become accustomed to the performance of your tires in conjunction with your motorcycle. http://chromoink.com/updates/brother-p-touch-pt-2710-manual.xml

Overloading causes excessive heat to build up in your tires. This can lead to sudden tire failure and serious personal injury or death while the tire is overloaded or at some later date. Before a trip, determine the total weight of luggage, equipment, and rider(s) to be added to your vehicle. A damaged tire can suddenly fail causing serious personal injury or death. Have your tires regularly inspected by your local dealer for damage. A tire may not have visible signs of damage on the tire surface. Yet, the tire may suddenly fail without warning, a day, a week, or even months later. Bumps or bulges may indicate a separation within the tire body. Have your tire inspected by a qualified tire service person. It may be necessary to have it removed from the wheel for a complete inspection. Wear on one side of the tread or flat spots in the tread may indicate a problem with the tire or vehicle. Consult your local dealer. If you have a bent or cracked rim, it must be replaced. An improper repair can cause further damage to the tire. It may suddenly fail, causing serious personal injury or death. To be safe, go to your local dealer for proper tire repairs. Aerosol fixers could contain a highly volatile gas. Always remove the valve core outdoors, away from sources of excessive heat, flame, or sparks and completely deflate the tire before removing it from the rim for repair. At this tread depth, the tire is worn out and must be replaced. Such tires cannot be properly repaired and must be replaced. Using plugs alone on any type of tire is not a safe repair. Such tires cannot be properly repaired and must be replaced. Thereafter, it should be treated as a non-speed-rated tire. This is especially important when the service operator inflates the tire. If the tire has been improperly mounted, it may burst with explosive force causing serious personal injury or death. http://www.drupalitalia.org/node/76783

Attempting to mount tires with improper tools or procedures may result in a tire explosion causing serious personal injury or death. This is a job for your local dealer or other qualified tire service location only. The tire must match the width and diameter requirements of the rim. For example, when mounting 16-inch diameter tires, use only 16-inch diameter rims. The rim must be free of cracks, dents, chips, and rust. The tire must be free of bead damage, cuts, and punctures. The tire service person must never inflate a tire beyond 40 pounds per square inch (psi)(276kPa) to seat the beads. Be absolutely certain beads are fully seated before adjusting inflation pressure to the level recommended for vehicle operation. Some rims require tubes. A “tubeless” tire must be installed on a “tube type” rim when the appropriate tube is inserted. Insure that the tube marking matches the radial tire marking before installation to rims that require tubes. Be sure to match your tire size to the size allowed on the rim. Improper rim width may affect handling and stability. Consult the sizing none of the tires you want to install for rim width allowances. Be sure that there is proper clearance between the tire and swingarm and any fender areas. Be sure to equip the bike with radial tires only when they are required by the bike manufacturer. Riding your motorcycle with an improper mix of radial construction tires with bias or bias-belted construction tires is dangerous. Your motorcycle’s handling characteristics can be seriously affected. You could have an accident resulting in serious personal injury or death. Consult your owner's manual or your local dealer, for the proper tire replacement. Consult the motorcycle manufacturer before equipping replacement Radial tires to insure the proper specification and combination for your motorcycle. Old tubes may become stretched and cause a crease which could make the tube fail. https://www.figlitornatialpadre.com/images/bridgeport-series-1-interact-manual.pdf

Check the size markings on the tube to ensure the tire size appears on the tube. Do not fit tubes in radial motorcycle tires, nor fit radial tires on rims requiring tubes, unless it is specified by the tire manufacturer. High-speed riding should be left to trained professionals operating under controlled conditions. Race tires are constructed in such a way that they are very unstable under normal street riding conditions. These tires also require higher operating temperatures for proper performance. These temperatures cannot be obtained within legal speed limits. The stress from this process may result in tread compound degradation and possible tire failure. Call 1-800-367-3872 for a referral for more technical tirename. If a service description IS NOT included, the tire manufacturer must be consulted for the maximum speed capability. If a service description is included with the size description, the speed capability is limited by the speed symbol in the service description. While these tests relate to performance on the road under those conditions, remember that real-life driving is rarely identical to any test conditions. Your tire's actual speed capability may be less than its rated speed, since it is affected by factors such as inflation pressure, load, prior alteration or damage, driving conditions, alignment, wear, vehicle condition, and the duration for which high speed is sustained. A tire's speed rating becomes void if the tire is repaired, retreaded, damaged or abused, or otherwise altered from its original condition. Thereafter, it should be treated as a non-speed-rated tire. The tire's speed rating designation appears on the tire sidewall with the tire size.Under some conditions, a tire may be spinning at a speed twice that shown on the speedometer. This could cause serious personal injury or death to a bystander or passenger and extensive motorcycle damage. https://lalitas-thaimassage-spa.de/wp-content/plugins/formcraft/file-upload/server/content/files/1628789a4909c5---Calculadora-casio-fc-200v-manual.pdf

Broken or loose spokes may cause wheel wobble, which can lead to instability and premature tire wear. Check rim tape condition. A protruding spoke can damage a tube and cause a tire puncture. Storage surfaces should be clean and free of grease, gasoline, or other substances, which can deteriorate the rubber. Improper storage can damage your tires in ways that may not be visible and can lead to serious personal injury or death. Use a clean, damp cloth to remove these chemicals from the tire. Never apply any other materials, cleaners or dressings to enhance sidewall appearance. These items may degrade the rubber and remove inherent ozone cracking and weather checking resistance. When you purchase replacement tires at an independent tire dealer, you should be provided with a registration card on which the tire serial numbers have been recorded. Be sure to fill in your name and address on this card and mail it promptly. You need not register tires, which come as original equipment on new vehicles, as the motorcycle and tire manufacturers handle that for you.

It is common for a jet airplane tire to carry loads as heavy as 60,000 pounds while operating at ground speeds up to 235 miles per hour. To accommodate these operational conditions, each tire has specific load and speed ratings. Tires are carefully designed and tested to withstand operation up to, but not necessarily beyond, these ratings. However, on occasion the speed rating of tires can be inadvertently exceeded during takeoff. This does not appear to be a new issue. Rather, advanced data acquisition tools on modern airplanes have made operators more aware of tire speed exceedance events. alrashed-alsaleh.com/userfiles/files/camera-manual-settings-explained.pdf

Boeing is not aware of any of these overspeed events resulting in thrown treads, which suggests that airplane tires in good condition can withstand these small speed exceedances without damage. However, it is important to remember that at high speeds, heat is generated within the tire structure. This heat, combined with extreme centrifugal forces from high rotational speeds, creates the potential for tread loss. Ensuring that tires are operated within their speed ratings will help prevent possible tread losses and the potential for airplane damage. While rotation and liftoff speeds are generally expressed in knots indicated airspeed, the tire speed limit is the ground speed, which is usually expressed in statute miles per hour. This means that a tire rated at 235 miles per hour is designed for a maximum ground speed at liftoff of 204 knots. Typically, this occurs when an airplane is dispatched at or near the tire-speed-limit weight and: Tail clearance and tail strike concerns are often the reason flight crews give for opting to use a slower rotation rate than recommended by Boeing. (More information about tail strike prevention can be found in AERO first-quarter 2007.) In addition, a slow rotation or under-rotation could significantly increase the runway distance required to reach the 35-foot point, which is another important reason for adhering to the Boeing-recommended rotation procedure. In comparison, the tire-speed-limit weight lacks any such conservative wind factor.The operator sporadically exceeded the tire speed limit even though the takeoff analyses showed a notable buffer between the tire-speed-limit weight and the actual dispatch weight. The airline approached Boeing for assistance. Under similar dispatch conditions on a This is in addition to the increase in all-engine takeoff distance associated with the slow takeoff rotation (see fig. 3). {-Variable.fc_1_url-

Based on many years of service experience, this approach seems to have worked well because very few, if any, tire tread losses have been attributed to an overspeed event. Based on this service experience, Boeing has typically not objected to this practice even though there is no overspeed takeoff capability specifically designed into the tire. At this time, operators, in conjunction with their regulatory agency, must determine the most appropriate maintenance action based on the tire-speed-limit exceedance event. By taking the following steps, flight operations personnel can reduce the possibility of tire-speed-limit exceedance during takeoff.

Bridgestone Aircraft Tire Europe uses it to check the air tightness of retread tires. Their main objective was to find a measurement technique that would make the decision (taking away the responsibility of an operator to make the decision) as to whether a tire is air tight, or whether it should be discarded. Bridgestone has assessed several techniques, such as loss of air pressure or infrared thermography. They opted for ultrasound air tightness testing after confirming that this method was the best to address their issue. The next step dealt with the validation of the measurement capability and repeatability of the ultrasonic technique. It consisted of testing the air tightness of all sizes of tire at different pressures, using an SDT portable instrument. Their aim was not only to check, on a large enough sample, that all leaking tires were detected as NOK, but also, that all airtight tires were rated as OK. Based on conclusive results, Bridgestone has entrusted SDT International with the development of an ultrasonic air tightness measurement system to be fitted on a new testing machine. The Principle of Ultrasound Detection After applying overpressure or depression to the part to be tested, the ultrasound technique consists of measuring the sound pressure level. This is achieved using sensors set around the part to be tested. If there is a leak, the air that is released through the leak hole generates an increase in sound pressure, thus raising the pitch of the sound. The technique therefore consists of the measurement of the sound level increase. The online system then issues a discard part alarm. The measurement of the sound pressure level is carried out over a frequency band typically centred on 40 kHz, hence the ultrasonic measurement name. Of course, the leak needs to be noisy enough to be detected. It is easily confirmed using a portable instrument. This technique shows many benefits. For instance, it is not sensitive to the temperature effect resulting from the part’s pressurization. The stabilization time is then eliminated and detection occurs immediately after pressurization. Bridgestone has developed a semi-automatic control machine. It includes an SDT Online4US system and 4 ultrasonic sensors set on the surface of the tire. The loading and unloading of the tire are the only manual operations. A mandrel system is used to clamp the tire, which is then pressurized. The PLC sends an order to the online system to start its measurement cycle. It also controls the tire rotation: It should perform at least one full revolution. Throughout the entire test cycle, the online system processes, individually and in real time, the signals delivered by the 4 sensors. It measures the signals and sends them to the PLC through a serial line. The decision on air tightness is automatic. It is no longer made by the operator. Detection and Localization of Leaks One of the outstanding features of the ultrasound technology is its capacity to localize the leak origin, in addition to its detection function: the closer the sensor to the leak, and oriented in its direction, the higher the ultrasonic signal. We then call it a local method. In Bridgestone’s case, by saving the tire’s angular coordinates when the ultrasound signal reaches its maximum, the PLC can determine the exact position of the defective area. When an air tightness fault is detected by the SDT Online4US system, after the testing cycle, the tire is presented in such a way that the incriminated area is placed in front of a laser marker. The operator can then confirm or not the presence of a leak and discard the tire. If the tire is in good condition, the operator can validate the test status. It allows the tire to proceed to the next steps of the retread process. After a predefined period of activity, airline companies return their aircraft tires to Bridgestone Aircraft Tire Europe, the leading aircraft tire retreading factory in the world, to have them refurbished. In addition to the layout of new gum, tires are subjected to a rigorous series of inspections. One of the tests consists of checking the air tightness criterion. The FAA (Federal Aviation Administration) recommends a maximum pressure loss of 5 percent over 24 hours in its decree AC20-97B. Designed for critical and remote access assets, its versatility is limited only by your imagination. This modular online monitoring system combines ultrasound, vibration, temperature and rotation speed measurements and provides a condition check-up of the tool and issues alarms in case of drifts. It monitors any type of rotating machine with 4 condition indicators and some electrical facilities. It also allows controlling the operating of valves, drain valves and steam traps and detecting leaks on gas fluid networks. The system allows the coupling of many standard interface sensors. Measurements are performed continuously and simultaneously on all connected sensors (up to 32 sensors inputs). Its large colour screen offers all user information and programming at a glance and a touch. The IP65 rated enclosure and sensors mean worry-free operation in the harshest environments. Quick cable management makes installation simple. The system offers a complete online asset condition management solution evolving according to needs. You can add measurement channels, inputs, outputs, and communication features. Pay for what you need today with the flexibility to scale the system for the future. By combining or adding required modules, the user can set up a customized control system to meet all requirements and production rates. Typically, air dryers have an average service interval of fewer than two years. The AVENTICSTM RDD (Roll-Up Desiccant Drying) and RDDmin air dryers have a service interval of eight years or 25,000 operating hours. But which ultrasound instrument works best. Which features are truly game changers. What should a program leader look for when procuring an expert ultrasound lubrication solution? One of the crucial factors in achieving production efficiency lies in choosing the right maintenance strategy. Typically, air dryers have an average service interval of fewer than two years. The AVENTICSTM RDD (Roll-Up Desiccant Drying) and RDDmin air dryers have a service interval of eight years or 25,000 operating hours. Thanks to the new collaboration, researchers will be better equipped to develop computationally demanding artificial intelligence applications for research and industry use. Two Nasa astronauts took the first all-female spacewalk. It was not just for fun, Christina Koch and Jessica Meir were responsible for replacing defective equipment from the International Space Station (ISS), and in that way also formed the first female maintenance team in the space. It is the ideal moment to reflect on maintenance in a European context. Euromaintenance is known as the summit for all involved in maintenance across Europe, it’s the place to be. The conference, with the support of the EFNMS, is the only commercially independent conference covering the topics we deal with in the maintenance world.
