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 and/or others. It could also damage
this Honda product 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 special tools. 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 his or her personal safety and the safe operation of this product.
If you need to replace a part, use Honda Genuine parts with the correct part number or an equivalent part. We strongly recommend
that you do not use replacement parts of inferior quality.
For Your Customer’s Safety
Proper service and maintenance are essential to the customer’s safety and the reliability of this product. Any error or oversight
while servicing this product can result in faulty operation, damage to the product, or injury to others.
For Your Safety
Because this manual is intended for the professional service technician, we do not provide warnings about many basic shop safety
practices (Hot parts-wear gloves, for example). If you have not received shop safety training or do not feel confident about your
knowledge of safe servicing practice, we recommend that you do not attempt to perform the procedures described in this manual.
Some of the most important general service safety precautions are given below. However, we cannot warn you of every
conceivable hazard that can 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 anytime you hammer, drill, grind, or work around
pressurized air, pressurized liquids, 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 engine-power equipment up in the air. Anytime you lift this product with a hoist,
make sure that the hoist hook is securely attached to the product.
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. 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 gasses from battery 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 store gasoline in an open container.
Keep all cigarettes, sparks, and flames away from the battery and all fuel-related parts.
Improper service or repairs can create an
unsafe condition that can cause your customer
or others to be seriously hurt or killed.
Follow the procedures and precautions in this
manual and other service materials carefully.
Failure to properly follow instructions and
precautions can cause you to be seriously hurt
or killed.
Follow the procedures and precautions in this
manual carefully.
