The symbols used throughout this Owner’s Manual are explained below.
II. SAFETY NOTICES Read and follow the information in the owner’s manual. Fully charge the battery after every trip and prior to using the scooter. If you do not frequently use the scooter fully charge the batteries every two weeks to prevent battery failure. If the battery gauge drops to red, charge the scooter as soon as possible. Completely discharging the batteries may damage the batteries, or shorten the expected life of the batteries. Batteries contain lead and lead compounds.
II. SAFETY NOTICES Avoid exposure to moisture, standing water, rain, snow, ice or salt when possible. Store in a clean and dry condition. Do not drive your scooter at night without proper lighting. Do not remove the anti-tip wheels. Keep your feet on the foot board at all times during operation. Do not stand on the foot board. Keep your hands and feet away from moving parts while driving.

III. SAFETY GUIDELINES GENERAL GUIDELINES Before operating your scooter fully read and understand this Owner’s Manual. Be sure to follow the setup instructions prior to using your scooter for the first time.
