Maintenance Data 
Operational precaution 
y  When remove the battery, the disconnection sequence of cable terminals shall be strictly observed. 
(First disconnect the negative cable terminal, next, the positive cable terminal.) 
y  The model of the spark plug and the tightening torque. 
y The ignition timing. 
y  Adjustment of headlight. 
y  Removal and installation of AC generator. 
y  The maintenance free battery requires no inspection of electrolyte level and refilling of distilled water. 
y  To recharge the battery, remove the battery from rack without removing ventilation caps. 
y  Unless in emergency, never rapid charge the battery. 
y  The voltage must be checked with the voltmeter while charging the battery. 
y  As C.D.I assembly does not require an ignition timing check. In case ignition timing is incorrect, check 
C.D.I and AC generator. Verify with an ignition timing light after replacement if necessary.
