Disassembly/adjustment prohibited items

A. 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.

B. 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 repre-
sentative screw may be marked with the red paint.

C. Variable resistors on board

NOTE
• Do not turn the variable resistors on boards for which no adjusting instructions 

are given in Adjustment/Setting.

D. Removal of PWBs

CAUTION

• When removing a circuit board or other electrical component, refer to “Handling of 

PWBs” and follow the corresponding removal procedures.

• The removal procedures given in the following omit the removal of connectors and 

screws securing the circuit board support or circuit board.

• Where it is absolutely necessary to touch the ICs and other electrical components 

on the board, be sure to ground your body.
