13. ACCELERATOR & BRAKE
● Before starting to work, ensure that the Power SW is OFF. Failure to
observe this can cause electric shock or short circuit.
● Use care so as not to damage wirings. Damaged wiring can cause
electric shock or short circuit.
● Do not touch undesignated places. Touching places not designated
can cause electric shock or short circuit.
● This work should be performed by the site maintenance individual or
other skilled professional. Performing work by non-technical personnel
can cause electric shock hazard.
● When performing work such as parts replacement other than those
specified in this manual, be sure to contact where you purchased the
product from. Confirm the work procedures and obtain precautions
from where you purchased the product prior to performing work.
Inappropriate parts replacement and/or installation with erroneous
adjustment can cause an overload or the parts to come into contact,
resulting in an electric shock, a short circuit, and a fire.
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.
