Toengineersinchargeof Repair or Inspection of our products:
Before repair orinspection, make sureto follow the instructionsso that customersand Engineers in chargeof repair orinspection can avoid sufferingAny riskorinjury.
1. Use specified parts. The system uses partswithspecialsafetyfeatures against Fire and voltage.Useonlypartswithequivalent characteristics when replacing hem. The use of unspecified parts shall beregardedasremodelingfor which we shall notbeliable. The onus of product liability (PL) shall notbeourresponsibilityincases where an accident orfailureisasaresultofunspecified parts being used.
2. Place the partsandwiringbackintheiroriginal positions after replacement orre-wiring.
For proper circuit construction,useofinsulationtubes, bonding, gaps to PWB,etc,isinvolved.Thewiring connection and routing tothePWBarespecially planned using clamps tokeepawayfromheatedand high voltage parts. Ensurethattheyareplacedbackin their original positions afterrepairorinspection. If extended damage iscausedduetonegligenceduring repair, the legal responsibilityshallbewiththerepairing company.
3. Check for safetyafterrepair. Check that the screws,partsandwiresareputback securely in their originalpositionafterrepair.Ensurefor
safety reasons there isnopossibilityofsecondary p oblems around therepairedspots. If extended
r damage is caused duetonegligenceofrepair,thelegal responsibility shall be withtherepairingcompany.
4. Caution in removalandmakingwiringconnectiontothe parts for the automobile. Disconnect the battery terminalafterturningtheignition key off. If wrongwiringconnectionsaremadewiththe battery connected, a shortcircuitand/orfiremayoccur. If extensive damage iscausedduetonegligenceof repair, the legal responsibilityshallbewiththerepairing company.
5. Cautions in soldering Please do not spreadliquidfluxinsoldering. Please do not washthesolderingpointaftersoldering.
6. Cautions in solderingforchipcapacitors
Please solder the chipcapacitorsafterpre-heatingfor replacement because they areveryweaktoheat. Please do not heatthechipcapacitorswithasoldering iron directly.
7. Cautions in handlingforchipparts.
Do not reuse removedchipsevenwhennoabnormality is observed in theirappearance.Alwaysreplacethem with new ones. (Thechippartsincluderesistors, capacitors, diodes, transistors,etc). Please make an operationtestafterreplacement.
8. Cautions in handlingflexiblePWB Before working with asolderingiron,makesurethatthe iron tip temperature isaround270.Takecarenotto apply the iron tiprepeatedly(morethanthreetimes)to the same patterns. Also take care not toapplythetipwithforce.
9. Turn the unitOFFduringdisassemblyandparts replacement. Recheck all work beforeyouapplypowertotheunit.
