1. Disassembly/adjustment prohibited items
1.1 Paint-locked screws
NOTE
▪ To prevent loose screws, a screw lock in blue or green series color is applied to the screws.
▪ The screw lock is applied to the screws that may get loose due to the vibrations and loads created by the use of machine or due
to the vibrations created during transportation.
▪ If the screw lock coated screws are loosened or removed, be sure to apply a screw lock after the screws are tightened.
1.2 Red-painted screws
NOTE
▪ The screws which are difficult to be adjusted in the field are painted in red in order to prevent them from being removed by
mistake.
▪ Do not remove or loosen any of the red-painted screws in the field. It should also be noted that, when two or more screws are
used for a single part, only one representative screw may be marked with the red paint.
1.3 Variable resistors on board
NOTE
▪ Do not turn the variable resistors on boards for which no adjusting instructions are given in Adjustment/Setting.
1.4 Warnings for disassembly
WARNING
• When accessing a hard-to-view or narrow spot, be careful
about sharp edges and burrs on the frame and parts.
They may injure your hands or fingers.
WARNING
• If it is absolutely necessary to service the machine with the
door open or external covers removed, always be attentive
to the motion of the internal parts.
A normally protected part may cause unexpected
hazards.
WARNING
• When removing a part that secures a motor, gear, or other
moving part, disassembling a unit, or reinstalling any of
such parts and units, be careful about moving parts and
use care not to drop any part or unit. During the service
procedure, give sufficient support for any heavy unit.
You may be injured by a falling part or unit.
