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 (e.g., Hot parts-wear gloves). If you have not received shop safety training or do not feel confident about your knowledge

of safe servicing practices, 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 equipment hoisted 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 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 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
