4. CHECKING AND ADJUSTING
• To avoid accidental short circuit, be sure to attach the positive cable to the positive terminal before the
negative cable is attached to the negative terminal.
• Never remove the battery cap while the engine operates.
• Keep electrolyte away from eyes, hands and clothes. If you are spattered with it, wash it away completely
with water immediately.
• Keep open sparks and flames away from the battery at all times. Hydrogen gas mixed with oxygen
becomes very explosive.
• If the machine is to be operated for a short time without battery (using a slave battery for starting), use
additional current (lights) while engine operates and insulate terminal of battery. If this advice is
disregarded, damage to alternator and regulator may result.

[1] BATTERY
Battery Voltage
1. Stop the engine and turn the main switch off.
2. Connect the COM (î›) lead of the voltmeter to the battery's
negative terminal post and the (+) lead to the positive terminal
post, and measure the battery voltage.
3. If the battery voltage is less than the factory specification, check
the battery specific gravity and recharge the battery.

Battery Terminal Connection
1. Turn the main switch on, and turn on the head light.
2. Measure the voltage with a voltmeter across the battery's
positive terminal post and the cable terminal, and the voltage
across the battery's negative terminal post and the chassis.
3. If the measurement exceeds the factory specification, clean the
battery terminal posts and cable clamps, and tighten them
firmly.

Battery Condition Indicator
1. Check the battery condition by reading the indicator (2).
• The factory installed battery is of non-refillable type. If the
indicator turns white, do not charge the battery but replace
it with new one.
