Description
• Observe the following precautions for safe and proper maintenance.
• Only qualified and appointed persons shall inspect, repair, or adjust the vehicle.
• Keep the workplace and tools clean.
Safe Work
• Do not run the engine in a place which has no exhaust ducts and which is poorly ventilated.
• Ventilate the workplace well and do not place a combustible thing there. Take extreme care when handling a combustible
thing or a hazardous material such as gasoline.
• Dispose of the replaced oil, parts washing oil, etc. according to laws.
• When working on parts which become hot, rotary parts, or sliding parts, take care not to burn or injure yourself.
• When working in a pit or a closed place, ventilate it to discharge harmful materials in advance.
• Do not work on the vehicle jacked up. When working on it, support it by the specified parts on wood blocks, etc.
• When lifting up the vehicle, support it by the specified parts and
apply a safety device.
• When removing a heavy part such as the engine, vehicle body,
etc. take care not to drop it by unbalancing it.
• Do not smoke while maintaining the vehicle.
• When maintaining the vehicle, take off rings and necklace to
prevent a short circuit in the electrical system.
• Before starting repair which does not need the battery power,
turn the key switch OFF and disconnect the negative (–)
terminal of the battery.
• Take care not to touch the hot metal parts just after stopping the
engine. While the engine is still hot, do not remove the radiator
cap or another part of the coolant system.
• Use the specified proper common tools or special tools for safe
and efficient repair.
