Charging the battery (fig. 59) Before charging the battery, it is best to remove it from the motorcycle. Remove the l.h. body panel (page 52), undo the screw (1) and remove the upper bracket. Always disconnect the black negative terminal (-) first, and then the red positive terminal (+). Warning Batteries develop explosive gases: keep it away from heat sources and flames. Charge the battery in a ventilated room. Connect the battery charger leads to the battery terminals - red to positive terminal (+), black to negative terminal (-). Important Make sure the charger is off when you connect the battery to it, or you might get sparks at the battery terminals that could ignite the gases inside the cells. Always connect the red positive terminal (+) first. Reinstall the battery on its mount and secure the upper bracket with the screw (1). Connect the terminals. Use some grease on the fastening screws to improve conductive capacity. Warning Keep the battery out of the reach of children. Charge the battery at 0.9 A for 5-10 hours. E 1 - + fig. 59 61
