Charging Battery

WARNING: Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the state of California to cause cancer and reproductive harm. Wash hands after handling.

Keep battery fully charged, especially during cold weather.

causym CAUTION: Never charge a frozen battery. Thaw at room temperature before connecting to battery charger. Only charge batteries in a well ventilated area. Disconnect both cables from battery terminals when charging batteries in machine.

Disconnect both battery cables and connect charger positive cable to "+" terminal and charger negative cable to "-" terminal.

Follow instructions provided with charger or reference the charging chart below. Always charge batteries with a 12-Volt charger.

Ventilate the area where batteries are being charged.

causym CAUTION: DO NOT charge a frozen battery. Warm to 16°C (60°F) before charging.

NOTE: Attach a ground strap to negative "-" battery post so ground connection can be made away from the battery.

IMPORTANT: DO NOT connect or disconnect live circuits. Turn off charger and connect ground cable last, away from battery.

Stop or cut back charging rate if battery cable feels hot, or is venting electrolyte. Battery temperature must not exceed 52°C (125°F).
