Group 177 General Safety Advice Never operate a diesel engine in an area where hy- drocarbon vapors (gasoline for example) are present or are suspected to be present. Hydrocarbon vapors can enter the air intake and make the engine over- speed, causing severe damage and/or explosion or fire. Serious personal injury or death can occur. Always chock the wheels before working under the vehicle to prevent it from rolling. Failure to do so can result in unexpected vehicle movement and serious personal injury or death could occur. When entering and exiting the cab, use caution. Al- ways have a firm hand hold and/or stable foot position before transferring weight to that position.
Do not carry anything when entering or exiting. Make sure the soles of your shoes and the cab steps are free from dirt, grease, oil or moisture before using the steps. Failure to do so can result in a fall, and serious personal injury or death may occur. If using a jack and/or jack stands, choose proper fault-free equipment. Failure to do so can result in equipment failures and personal injury or death may occur. Note: During the Preventive Maintenance inspection, check the condition of warning labels on the vehicle. If a label is damaged or defaced to the point where the mes- sage cannot be read, note on the inspection form to have it replaced. 7
