10. CONTROL UNIT (GUN)
In order to prevent any electric shocks or short circuits, be sure to turn the power off before performing any work that involves touching
the interior parts of the product. Be careful not to damage the wires. Damaged wires may cause electric shocks or short circuits, or present
a risk of
fi
re. Be very careful when soldering. Handling a soldering iron carelessly may result in a
fi
re or burns.
When securing the plastic-made parts, do not excessively fasten screws and nuts. Failure to do this may damage the parts, and
fragments resulting from damage may cause injury. When reassembling the Control Unit (Gun), be sure to check the connecting portion
and the trigger, etc. If the reassembly work is insuf
fi
cient and/or incorrect,
fi
ngers may be caught and result in injury.
Make sure that there is no gap when attaching cover L and R. A gap or crack may trap hands or
fi
ngers and lead to injury.
Do not cut the tie belt securing the wires in the Control Unit (Gun). Cutting the tie belt may cause malfunctioning of the wire connection. If
you cut the tie belt when replacing the wire etc., be sure to secure the wires using a new tie belt as before. After taking the Control Unit
(Gun) apart, always use “Tightening Adhesive” (part number: 090-0012). Apply an appropriate amount to the screw and then tighten it
up. If you do not use “Tightening Adhesive” there is a risk of looseness or the Control Unit (Gun) coming apart. Only use the tightening
adhesive speci
fi
ed by this manual. Using any other “Tightening Adhesive” may cause a chemical reaction that renders the screws useless or
damage the surface of the Control Unit (Gun). Follow these directions carefully to avoid damaging or losing small parts. After exchanging
any parts, always enter Test Mode and adjust/check the Control Unit (Gun).
If there appears to be a problem with the gun and adjustment in Test Mode makes no difference, part of the gun is most likely broken. Use the
following instructions to take the gun apart and replace the broken part. The exterior casing, comprised of cover L and cover R, must be opened
up in order to change interior parts. As some internal parts are connected to cover R, work with cover R face down on the working surface.
