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 man-
ual and other service materials carefully.
Failure to properly follow instructions and precau-
tions can cause you to be seriously hurt or killed.
