• After disconnecting the batteries, wait 90 seconds for the controller capacitors to discharge.
• If wires are removed or replaced, make sure wiring and wire harness is properly routed and secured.
Failure to properly route and secure wiring could result in vehicle malfunction, property damage,
personal injury, or death.
• Lift only one end of the vehicle at a time. Use a suitable lifting device (chain hoist or hydraulic floor
