A Few Words About Safety

Service Information

The service and repair information contained in this manual is intended for use by qualified, professional technicians.

Attempting service or repairs without the proper training, tools, and equipment could cause injury to you or others. It could also

damage the vehicle or create an unsafe condition.

This manual describes the proper methods and procedures for performing service, maintenance, and repairs. Some procedures

require the use of specially designed tools and dedicated equipment. Any person who intends to use a replacement part, service

procedure or a tool that is not recommended by Honda, must determine the risks to their personal safety and the safe operation of

the vehicle.

If you need to replace a part, use genuine Honda parts with the correct part number or an equivalent part. We strongly recommend

that you do not use replacement parts of inferior quality.

arise in performing service and repair procedures. Only you can decide

whether or not you should perform a given task.

Important Safety Precautions

Make sure you have a clear understanding of all basic shop safety practices and that you are wearing appropriate clothing and

using safety equipment. When performing any service task, be especially careful of the following:

· Read all of the instructions before you begin, and make sure you have the tools, the replacement or repair parts, and the skills

required to perform the tasks safely and completely.

· Protect your eyes by using proper safety glasses, goggles or face shields any time you hammer, drill, grind, pry or work around

pressurized air or liquids, and springs or other stored-energy components. If there is any doubt, put on eye protection.

· Use other protective wear when necessary, for example gloves or safety shoes. Handling hot or sharp parts can cause severe

burns or cuts. Before you grab something that looks like it can hurt you, stop and put on gloves.

· Protect yourself and others whenever you have the vehicle up in the air. Any time you lift the vehicle, either with a hoist or a jack,

make sure that it is always securely supported. Use jack stands.

Make sure the engine is off before you begin any servicing procedures, unless the instruction tells you to do otherwise.

This will help eliminate several potential hazards:

· Carbon monoxide poisoning from engine exhaust. Be sure there is adequate ventilation whenever you run the engine.

· Burns from hot parts or coolant. Let the engine and exhaust system cool before working in those areas.

· Injury from moving parts. If the instruction tells you to run the engine, be sure your hands, fingers and clothing are out of the way.

Gasoline vapors and hydrogen gases from batteries are explosive. To reduce the possibility of a fire or explosion, be careful when

working around gasoline or batteries.

· Use only a nonflammable solvent, not gasoline, to clean parts.

· Never drain or store gasoline in an open container.

· Keep all cigarettes, sparks and flames away from the battery and all fuel-related parts.
