10. ACCELERATOR & BRAKE
Be sure to turn power off before performing work, and avoid touching undesignated places. Failure to do so can result in electric shock and short circuit accidents.
Be careful so as not to damage wirings. Damaged wiring can cause electric shock and short circuit hazards.
When performing work such as parts replacement other than those specified in this manual, be sure to contact the company the product was purchased from and confirm the work procedures and find out any precautions prior to performing the work. Inappropriate parts replacement and/or installing with improper adjustment can cause an overload or the parts to come into contact, resulting in electric shock, short circuit, or fire.
After having performed the adjustment or replacement of the volume, be sure to check the variation of the volume value under INPUT TEST in the test mode.
If Accel and Brake operation is not satisfactory, adjustment of Volume installation position or Volume
replacement is needed. Also, be sure to apply greasing to the gear mesh portion once every 3 months.
