User manual YAMAHA YT-220

[. . . ] Turn the power switch OFF before unplugging the motor power cord from the AC outlet. ⷠIf the motor should automatically shut off for any reason, turn the power switch OFF and eliminate the cause of failure. After a few seconds, the power can be turned ON, and the motor will run normally. [. . . ] ⷠAvoid places with high temperature or humidity and do not store in direct sunlight. ⷠNever use wetted cloths or solvents such as thinner or benzine to clean the instrument. ⷠAlways apply the caster brakes except when moving. Top quality materials for tone bars The clear and soft tone produced by the tone bars is a result of using the finest quality aluminum alloy possible. To prevent rust and give a soft, satin-like finish, the tone bars are finished with a hairline silver alumite finish. Perfect Tuning Tuning technicians use their highly trained ears as well as strobe tuners to tune each individual tone bar. To assure accurate pitch, tuning is performed on the overtones of each tone bar as well as its fundamental pitch. Tuning is performed to the same level as concert and pro use instruments to ensure that pitch is perfect and even over the entire range. Easy to use, lightweight yet sturdy frame. At the bass end, first, attach the pedal stay as shown by A, then attach the leg stay below the pedal stay as shown by B in the diagram below. Place a washer between the wing bolt and the stays and firmly tighten into place. At the bass end of resonators, if the room temperature is more than 22 °C (72°F), insert resonators into the shallower grooves; if room temperature is less than 22°C (72°F), insert resonators into the deeper grooves. At this point assembly for models YT-220/280D is continued with step #11 "Adjust the pedal stroke" on page 12. After completing the assembly go back and make sure all wing nuts are tightened firmly. There are two controller mounting pins on the high sound side of rail (1). Align the two holes in the controller mounts with these pins and hook the controller onto the pins one side at a time. Connect the MOTOR IN terminal of the driver with the MOTOR OUT terminal of the controller using the supplied 8P DIN cable*. To connect align the arrow mark ( ) on the plug with the screw next to the jack. [. . . ] * In case the 8P DIN cable is misplaced, the following spare part may be ordered: First, wrap the synchro belt around the driver pulley and then carefully slide it over the fan side pulley. * Note For Service Personnel If the belt cannot be mounted because the distance between pulleys is too wide, or the belt slips due to a too narrow pulley distance, loosen the two driver positioning screws (see illustration below) to adjust the pulley distance (belt tension). * In case the belt is misplaced or worn, the following spare part may be ordered: Loosen the center rod fixing bolts to adjust the protruding length of the center rod to the desired pedal stroke, and retighten the bolts.
