Maintenance Data:
Operational Precaution
• When removing the battery, the disconnect sequence of cable terminals should be strictly observed
(First disconnect the negative cable terminal, next, the positive cable terminal.)
• The model of the spark plug and the tightening torque.
• The ignition timing.
• Removal and installation of AC generator.
• To recharge the battery, remove the battery from rack without removing ventilation caps
• Unless in emergency, never rapid charge the battery.
