Do not work on this equipment when mentally or physically fatigued. GUARD AGAINST ELECTRIC SHOCK Disconnect electric power before removing protec- tive shields or touching electrical equipment. Use rubber insulative mats placed on dry wood platforms over floors that are metal or concrete when around electrical equipment. Do not wear damp clothing (particularly wet shoes) or allow skin surfaces to be damp when handling electrical equipment. Disconnect batteries to prevent accidental engine start. Jewelry is a good conductor of electricity and should be removed before working on electrical equipment. Use extreme caution when working on electrical components. High voltages cause injury or death. Follow all state and local codes. To avoid possible personal injury or equipment damage, a qualified electrician or an authorized service representative must perform installation and all service. Exhaust gases contain carbon monoxide, an odorless and colorless gas. Carbon monoxide is poisonous and can cause unconsciousness and death.

It symptoms persist, seek medical atten- tion. Shut down the unit and do not operate until it has been inspected and repaired. Protection against carbon monoxide inhalation includes proper installation and regular, frequent visual and audible inspections of the complete exhaust system. 1-PIEM
