Before starting the engine, check the oil and coolant levels. Look for: * Leaks. ¢ Loose or damaged parts, especially in fuel or exhaust systems. * Worn or damaged belts. « Any change in engine appearance. ¢ Odor of fuel-gas. 7-5 Check Operator’s Report or Log-sheet The engine must be maintained in top mechanical con- dition if the operator is to be safe and get optimum sat- isfaction from its use. The maintenance department needs daily running reports from the operator to make necessary adjustments in the time allotted and to make provisions for more extensive maintenance work as the reports indicate the necessity. . Comparison and intelligent interpretation of the daily report along with a practical follow-up action will elimi- nate most failures and emergency repairs. Report to the Maintenance Department Any of the foliowing conditions: Low lubricating oi! pressure. Low power. Power increases or governor surge. Abnormal water or oil temperature. Unusual engine noise. Smoke. Excessive use of coolant, fuel or tubricating oil. Any fuel, exhaust, coolant, or lubricating oil leaks. Fuel-gas odor. Erratic or no throttle control or response. Check and Bring to Proper Level ¢ Engine Oil Level - Checking Never operate the engine with the oil level below the ADD mark or above the FULL mark. Wait at least 5 min- utes after shutting off the engine to check the oil level. This allows time for the oil to drain to the oil pan. The oil level should be as close to the FULL mark as possible.
