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
bums or cuts. Before you grab something that looks like II can hurt you, stop and put on gloves.
Protect yourself and others whenever you have Ihe vehicle up in the air. Any time you lift the vehicle, either with a hoist or a Jack,
make sure Ihat 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 othelWise. This will
help eliminate several potential hazards:
Carbon monoxide poisoning from engine exhaust. Be sure there is adequate ventilation whenever you run the engi ne
Burns from hot parts or coolant. let the engine and exhaust system cool before working in those areas.
Injury from moving parts. If the lnstruction tells you to run the engine , be sure your hands, fingers and clothing are out of Ihe way.
Gasoline vapors and hydrogen gases from batteries are explosive. To reduce the POSSibi lity of a fire or explOS ion, be careful when
working around gasoline or batteries.
